Dunlop K70 a bit shite ?

 Maybe the motorbike shop is looking at the K70's from a moto GP perspective. I certainly hope so.

 Dunlops K70 was at one time the AMA specified Class C racing tire.
Times and technology have changed and the K70 has long been surpassed as the race tire to beat but it is still more sporty than most people actually need and they continue to serve many, many satisfied riders the world over.

Great tire for our bikes. I bet the motorbike shop has never even seen or sat on a RE with K70s! Go for it and you will love it.

 I currently have a pair of K70's on my Bullet and can attest to their superb grip, stability and response.

K70 is a damn fine tire.  it is soft, so, the lifespan is reduced.....  but, it is the best all-purpose tire around.

You cannot do better for the price. You cannot do better for the bike on pavement and retain the old time look. Go for it. I did after quite a bit of research.

Hi steve,like they said great tyres cheap and sticky. i got about 8k from my last rear and the front is still good at 14k.  i suspect the shop dude is trying to extract more of your wallet contents. they're great on the dirt too.cheers.

sounds great. yeah i doubt they know anything about RE. So whats a good size for a C5 with 110/80-18 rear and 90/90-18 front? He tells me the sizes are limited in the K70's.

The only k70s (I'm told) available in oz in 18's are 400/18. At present there is only about 1cm clearance each side between front tyre and mudguard . Problem is I can't see the tyres. Thy need to be ordered and if they're wrong I'm stuck with them- just like I'm stuck with the 10 year old metzlers that won't mount.

Oz, guess that the price to pay to live in a enchanting place.. Just make sure when u order tyres that u are careful. Everyone who has the k70's love them for street riding..I'm still on the Avons but I'm not in a big hurry to change up ..That stated, they seem to last a long time and handle the dirt/gravel roads at a good clip, not sure the k70's  are as effective in that manner....

I just put k70s on my Iron Barrel.  I put the rear one on a month back then just last week brought the front in to the shop nearby my house for them to do and dude says to me: "Let me get this straight, you want me to put on an inferior tire to the one you have currently which is fine (a stock avon)."  Ummm...yes.  Never going back there again.

But anyway, love the tires.  Look good, feel good.  When these wear out they will be replaced by k70's.

I have my balancing done at the local Triumph dealer and the mechs have commented about the K70 being great tires.  I haven't had any problems in rain, wet pavement, anything really.  They stick to the road well.

I had three sets of 3.25-19F and 3.50-19R on my G5. I ran the hell out of them, no wanker stripes, but they handled quite nicely. They were on good for 3500-4000 miles, but they were very satisfying. For the price I felt the short life vs handling was worth it. I did change to Pirellis MT66s as the last set on the bike. They were even better handling and were appearing to last a lot longer than the K70s for about $20 more. I recommend the Pirellis over the K70s, or any of the other tires that I have second hand experience with.
They are essentially the same in feel as the Pirelli Sport Demons that are supposed to come on the cafe racer and that My Guzzi came with. I'm lovin' 'em.

Thanks all for the replies and thank you for the chart bullet man. i was looking for that :)
Im confused(again) THe avon roadrider AM26 chart says that the imperial measurement is 3.8 on front and 4.4 on the rear. Then you guys say youre using 3.25 front and 3.5 rear.
Just trying to find a motorbike shop that has a clue is hard. I guess once you find a source its all sweet, but its alot of ringing around initially!

The 3.25 front and 3.5 rear are the stock tire widths that come on all of the RE's sold in the US.
I don't recall what it is but there is a limit to how wide the tires can be before they start rubbing on things.

As a side note, I'm running the Dunlop K70 3.25 X 19 on the front of my G5 (Electra) and have over 2000 miles on it.
I don't ride like bare does so while he only got about 4000 miles out of his K70's, my front tire shows very little wear.  I wouldn't be at all surprised to get well over 8000 miles out it it before it needs replacing.

 3.50-19's are mounted front and rear on my Iron Barrel.
The UCE Bullets have more distance between the arms of the of the swing arm than the I.B.'s do.

 I should raise the front mudguard by a bout 3/4 inch just to be safer.

"In K70 , 4.00*18 is the only 18" we bring into Australia. There is another tyre called TT100GP available in (heaps of sizes etc) "

This was the mail message from Dunlop Australia.

So the moral of the story here is: no you cant buy K70's in Australia for a 2012 C5 with 18 inch wheels from Dunlop.

I thought I read in one of the other many tire/tyre threads that the 2012 C5 (19" front and 18" rear) would accept up to a 4.10 rear?

If so, the K70 at 4.00 for the rear would fit.

If you want the same pattern, look for a 3.5x18 Kenda K265 for the front tire/tyre.  It has an identical tread pattern as a K70 and might be easier to find in Australia.  This is also on EBay and Amazon....cheaper than K70, little less heavy duty, but works just fine.  You can also put the Kenda 3.5x18 in the rear of the C5.  I ran these for a few months before I put in a 19" front wheel.

Another option is to put a 3.5x18 Kenda up front and a 4.0x18 Dunlop K70 in the rear and you will be all set.

Did a little more searching and the TT100 is known in the USA as the K81.  Those familiar with the K81 can give you their opinions on it - supposedly comparable to the K70?

K81 got the moniker "TT100" for being the first tire to do an average lap over 100 mph on the Isle of Man course on Malcolm Uphill's Triumph in 1969.  They were the tire for the 70's.

the rear isnt the problem. ill get the 4.00 on there. the problem is what to put on the front. no way the 4.00 will go on the front without hitting the guard.
I bought some metzler lasertecks. Will see how they go.
Yes can get k81. maybe next time! gonna be doing alot of dirt tracks at xmas, so ill give the k81s a burl then.

I pulled a K81 off of the rear of the Blackhawk before I installed the Shinko 705s.  The K81 was a fine tire and handled both pavement and dirt quite well, but I don't think it would handle loose dirt very well.  It still had new tread on it, but the bike sat for over 20 years and the rubber was dry rotted and weather checked, so I needed to replace them.  I will say that the Shinko 705s are the best dual sport tire I've ever run on any bike.  My friends' BMW GS650 that I just did an adventure ride on over the weekend also has the Shinko 705s.  I had them up to 55mph on loose dirt roads and up to 95mph on the pavement, never once skipped a single beat.

The front K70s probably would have made 8000 miles. The rears are the short lived ones. But I changed them as pairs. The tire changing guys got some pretty good front tires to of the deal.
As for the Metzeler Lasertecs vs Pirellis, the Guzzi comes with either of them and the the Pirellis are preferred for better stability and roadholding.

Many early C5s had a tendency to wobble at high speeds due to their frame and fork geometry.  RE corrected this by first adding 19" front wheels and calling it a C5 "special" and then they completely changed the front fork to straight shocks without the offset at the lower end to fix this issue.  Nfieldgear sells a 19" wheel and spoke kit for this and Hitchcocks sells complete 19" slightly used wheels for the C5.  I had cured most of the wobble by other tweaks, but decided to put it to rest by lacing up a new wheel.....best decision ever and the resulting ride with the K70s is perfect.

for everyday riding you will be fine.  However, a racetrack star would probably have a different opinion.

If you have a Skidmaster on the back, it will make a big difference on how well the bike steers. Since the Avon is designed for sidecars, it is very flat across the profile. This slows down the steering considerably and doesn't have much rubber on the ground as the bike leans. The bigger question is how do you ride? Do you just putter around and never challenge a turn? Or do you like to kinda to "tear up the Twisties"?. If the former, it doesn't really matter what tire you run. If the latter, your best bet was to have gotten rid of that rear tire yesterday! You would like the way the bike steers much better if you do get rid of it. Just about anything is better!

Bare, how do you like that Moto Guzzi? It looks like one hell of a great machine.

The Guzzi is quite nice. I've got just about 4000 miles on it now,and we are getting on quite nicely. it handles great and sticks really well with the Pirellis. It's not particularly fast, but it will do the ton. It's been averaging 52 mpg, a long way from the Bullet, but it's got the performance to justify it. It's not quite as comfortable as my Bullet was, but it's close enough for gummint work.
It's not much of a challenge to ride as the Bullet was. I don't have to judge car passes or steep hills, it just goes!
It does get attention, almost as much as the Bullet. Most people think it's an old bike. I wish I could've waiting for the RE Continental, but that was 3 months and 4000 miles of riding I would've missed and still be missing, so I'm really glad I bought it!

The V7 Racer is just a super cool looking bike.  I'm betting if you really want the Continental when it gets here, you could sell/trade the Guzzi and have enough capital to get it.  Though at 535cc and with more HP, it may be closer to Guzzi perfomance than your old steed.

Jack and I discussed getting another one, but we kinda decided we'd "been there, done that", and it was time to move on!
However, the dealership where I got the RE has been considering getting the Guzzi dealership. They're in the process of buying a new location and when they finish moving, they are going to look into it. Be fine with me, I like those guys!

 Plenty of clearance in the rear and just enough up front for road riding.
We do ride in the rough however and a bit more space between the front tire and fender will be welcomed to more easily pass rocks picked up by the tread.

Only thing that matters, is not the mixing of the two, but that the stock rear "skidmaster" just i'snt good enough to keep using. I didn't feel safe on mine, & suggest you replace yours. I'm running a 3.50X19 CHING SHIN  K70 Clone on the rear, they were great tires but no longer available. My new front Dunlop 3.25X19  K70 was "made in Japan" with a more modern rubber compound than the old Brits had. They both work great for general utility, or sporty riding.

When mixing and matching front and rear tires the most important thing is never to get a stickier back tire.  If one tire is going to let go at the limit, you don't want it to be the front.  That said, when mixing tires the profiles and lots of other characteristics of the two may or may not work well for any given bike.  Also a bad idea to mix one bias ply with one radial.

 The Safety Mileage is a good rear tire for plodding about and served me well as a commuter tire. It outlasted three Speedmaster MkII front tires. I only replaced it ( with another SM ) due to age hardening and cracking.  The replacement SM is still serviceable and is tucked away along with the SMkII front for just in case.

 The square shoulder of the S.M. does make for an "interesting" riding experience at hard lean angles. By that I mean that in a good lean when the tire is riding up on the shoulder it feels like a tug of war is going on in rear and the bike wants to both dive down and stand up at the same time.

 The contact patch in between tire and road at that position is incredibly small and the rubber is of harder compound. There is absolutely no room for error.

 In theory a K70 up front would be an improvement over the straight rib SMkII front especially in the wet and on steel deck bridges but I would not mix it with a S.M. rear as it would make it that much easier for me to get up on that tires square shoulder.

 Out of necessity I have mixed and matched tires types in the past as a short term "get me by for now" type of thing but was acutely aware of the risk and consequences. I recommend against it.

  The K70's mounted on TIMEX now have more grip than the K70's I remember from the past. Certainly they allow for a more sporty ride than the standard tires. Whats more important though is the increase in traction that affords a wider margin of safety in normal riding.
No matter where you go, there, you are.

I've been discussing the mounting of a K70 3.5x19 tire on the front wheel of the B5, which has the fully strutted fender and fork cover tubes like the C5.  I currently run 3.25 front, 3.5 rear, but it's just too darn cold (below zero F) in my garage right now for me to go poking around trying to estimate how the larger front tire would fit under the fender.

Am I correct in stating that the only difference between the sizes is the width?  If so, the tire should easily clear the fender - except maybe for where the fender bulges inward on the sides to clear the fork cover tubes.  Anybody put any thought into this, or try it?

EDIT:  I found this other post

http://www.enfieldmotorcycles.com/forum/index.php/topic,16727.0.html

discussing this very issue, but no real resolution.  Boots, did you ever mount the 3.5 K70 on your B5?

Tires with that sizing standard have a 100% sidewall, so a 3.5 is .25 taller than a 3.25.  Should be fine.

We once tried to fit a 4.1 on a G5 front.  It fit but the clearance was too close for comfort so we didn't run it.  I suspect the 3.5 would fit just fine.

The small number in non-metric tire sizing is the cross width of the tire, not the height.   A 3.5" tire is going to be .25" WIDER than a 3.25" tire, not taller.  To it can be confusing because when you put a wider tire on a narrower rim it forces the tire upward making people think it's taller.

I believe it's both the width and the height.  That sizing system assumes 100% sidewall, so tires are as tall as they are wide.

That stated, they seem to last a long time and handle the dirt/gravel roads at a good clip, not sure the k70's  are as effective in that manner....

The K70s outperform the Skidmasters in any situation except treadlife. But they are are superior in any situation that has anything to do with keeping the painted side up! Or the rubber side down.

I worked that on my 130/80-17 Sport Demons. The calculater works out a diameter of 24.19" diameter.
I measured the circumference of my tire by marking the tire and floor and rolling it one revolution, then dividing the result by Pi. Also measured the diameter as well as I could. The diameter came out to be 24.67".
This equates to about a 2.5 mph difference  at ~120 mph.
Close, but no cigar.

Gents,

I am really very sorry for not having responded to your inquiry sooner, but I honestly haven't been on the Forum ever since I got rid of the Bullet.

So, I did indeed fit the 3.5 K70 on my B5 and it LOOKED AWESOME! It was a tight fit under the full fender of the B5, but it did indeed fit. Lots of riders loved the look and commented on it. However, the bike seemed a bit more "floaty" and handling was hampered in the sense that it wasn't able to fall into corners nearly as easily as before. High speed cornering was much stiffer and required more effort. Also, low speed handling was definitely hampered. Now, this of course is a question for the individual. Do I go for looks over performance? It depends upon the riding you do. Are you carving canyons? If yes, then I wouldn't advise it.

I originally did this in an attempt to to steady the ride on freeway rain grooves, but it did nothing to mellow the wobbles. I loved m B5, but the harmonic speed wobbles that I encountered on rain grooves ultimately sealed the bike's fate.

Last summer I traded her in on a 2013 Crystal White Triumph Bonneville. In all honesty, I haven't looked back. The Bonnie is rock steady on rain grooves, confidence inspiring in the mountains and very capable for long haul touring. Recently I added some performance pipes and a remap of the EFI so the bike runs and sounds like true Bonnie. To each his own.

I wish you all the best,
Boots

Sorry, I only have  few pics of the B5 from when I first got her, none with the K70 up front.  :(

But I have attached a pic of the fellow from the Her Majesty's Thunder blog. He runs a 4.0x19 Domiracer tire up front and back I believe. I think it looks awesome! This is just how the k70 looked and fit under the front fender of my B5.   ;)

Cool! Chris' bike looks awesome with those tyres.

Just to confirm, the 3.5 didn't rub against the front fender where it kind of 'bulges' inwards for the fork legs, right?

Putting the big ROCK CRUSHERS on it will be an EXPENSIVE MISTAKE. Who would willingly make their bike handle like a pig. Pretty sure I mentioned this several times already. The bike handles best with the stock size tires, K70's are a very good choice.  Spending the money you save on fancier riding gear will help your image far more than Tires to make it less fun to ride..
Just my experienced opinion.

The Stock rear tire on my G5 Deluxe IS 3.5, It could use a 3.25 on the rear. I would NEVER put anything bigger than a 3.25 on the front.  I would call anything on the rear BIGGER than 3.5 a Rock Crusher.  Who would willingly run miles in Construction Work Boots? - same principle.

+1 Although I will have to add that putting on the 90/90-19 and 100/90-19 Pirelli Mt66s actually improved both the steering and stickiness on the bike. These are both front tires, so the arrow needs to be flipped backwards on the rear. They were only a few dollars more than the K70s from Bike Bandit and were destined to last a lot longer. Unfortunately the bike was crashed before I got to wear them out through no fault of the tires.
And you guys know I am a great fan of the K-70s, but the Pirellis are better.

 :D Sure the 3.25 is the desired size at the front, but I am willing to experiment. Call the 3.5 a rock crusher, but I am sure the little change in handling is not going to bother me a lot. I am not going at light speed here like an R1, CBR1000RR, Panigale or S1000RR, nor I will be doing the Isle of Man TT on an Enfield Bullet.

I will be riding for pleasure...whether it be city/town or the twisties, and I am prepared to put an extra effort in entering a corner with a 3.5 up front. It can't be that bad and I am sure I can drag the left footpeg + right brake arm all day long with the 3.5 up front also.

Again, this is my personal choice and will surely report on the ride when I swap to the K70s. Craig, do not get angry at me for this lol, I am 22 and I am a little rebel  :-X

I have been riding old or antique BMW's for 44 years.(Just got my first new C5). Two things I have done to every one, from the little 250 R27 to the five R100S/7's. Remove stock handelbars for low sport bars. Second, as soon as practical, put on K70s. The combination looks good (to me) and the ride is proper. I will do the low handlebar to the C5 and K70 my tires as soon as needed......my opinion!

Hi Tom, You could consider your K70's right away, nothing is getting any cheaper. Selling your "Take Off, Nearly New" Tires on Ebay will nearly pay for the upgrade. I used SUPERBIKE Brand Euro type Low Bars from Bike Bandit @ approx. $25., Think I got the K70's there as well.

FWIW, it seems almost everyone who has changed tires, no matter what they changed to, has liked what they got better.  I put Bridgestone BT 45s on my C5.  The Avons were ok but always felt a bit vague.  The BT45s track like they're on rails and stick better in the wet.

What Avon's are you talking about?
Since you mention C5 I assume you refer to Speedmasters? Which indeed have not a good reputation for our kind of road surface.
On the G5 Avon Roadriders (AM26) are mounted which are very long lasting and excellent on all roads, mud excluded ::)

Yes, the Avon AM26 Roadriders.  They were ok but did not track well when leaned over.  The reward was easy to skid, especially in the rain.  Acceptable, but the BT45s are sooooooo much better.  They did last over 10k with no too much wear.

I've got my third Sport Demon rear and second front sitting in the garage. I got 6500 mile put of the first rear tire and coming up on 10000 miles the front original still has a couple of thousand left in it. I am spending slightly less for the Pirellis than I was for the K70s with the additional mileage. The Mt66s would have been considerably less on the Enfields.

Please, it's the corsa not the strada; so enduro tires. Max speed is 150 kph (95 mph), would make the Ducati shake with laughter.
However there is a lot by Ducati in our new bullets, so...  ;D

Here, they are at competitive prices:
Pirelli MT60 corsa = 92.98 euro
Dunlop K70 = 95.48 euro
