Ok sorry to jack your thread. But iv been wanting different tires also but I'm have trouble finding the Front :-100/90-18, Rear :-130/70-18. What other sizes will fit our stock wheels with out modifications to the bike.

This is what I installed and you can see more details on my build thread.

Well many bikes have fast or slow steering BMW have always been slow, when you look at bikes like the X7 or RD these can be considered fast steering bikes really all bikes steer and handle slightly different no two bikes are exactly identical, it depends on a lot of factors weight wheel size and a number of other factors.

So are you saying "It's about the rider"?     (joke about another thread)

I get the reference 
What I'm getting at is when racing, closed track conditions allow very small adjustments to make noticeable changes.
Street riding (even fast street work) is so far away from the racing edge all of those little adjustments don't make a huge difference. For me it's adjust the rear shocks for comfort and when I mix it with friends on a mountain pass I move my weight left, right, forward and back depending on the corner. When we stop for coffee or a beer we talk about how well or badly we went through a certain corner, not how much money we invested into the thingamajig.

I like the concept of... "how well do you ride with what you got". I have had much faster (greater HP) motorcycles and this RE has the power where you need it. I rather have less HP and then stop at coffee shop and tell my friends with 600cc or 1000cc... "What happend? Your engine not working for you.... "  hahaha

They must be around somewhere. It's a common size. If you get really stuck get them sent from revzilla.

FWIW you could go up a size and not notice any significant difference. It's no biggie. I'm running 110 and 150 size in rims meant for 100 and 130 (takeoffs from my track bike cause I'm cheap) . They look a bit stupid but they work OK. Edges are a bit worn out but on the skinny rims, I'm not geting to the edge on the street.

The only things I know about them is that they are horrendously expensive and as a race tyre they will not last long on the road and unless you have good quality suspension you will thrown through a hedge long before you ran out of grip.
what do you want them for? Grip? there are plenty of other tyres out there with plenty of grip. Looks? that's up to to you, the GT is a slow turning bike and those tyre sizes will slow it down even more. Bigger is not always better.
When I replace my tyres it will be with the Conti Road Attack3 in OE sizes.

There’s no reference to racing compounds on the Continental website, and they actually refer to them as street tyres. I got the feeling that they were for older bikes that wanted bigger tyres for classic racing, and made specifically for older narrow rims. Also, my quoted sizes keep the relative front/rear aspects similar to OEM which I would think is more important per steering/ handling than simply tyre size. And, yes, I just don’t like skinny tyres😁

Bigger was an improvement for me; was using all the tread on OEM tyres and now I have a few mm margin. I think 140/70 and 110/80 are spot on for our rims.

Agreed. The original sizes and tires are just fine. But having to use the whole tire on a imperfect surface would let it scratch its way to the outside. Even then it was well behaved. These bikes really do handle very well.

But now using 110 /80 F & 150 /70 R I don't even think about the tires.

So, the downloadable brochure makes a point of which of the tyres in that range need tyre warmers. It says the CR is street legal and no mention of warmers. Makes it seem like you're good to go. prolly best to run it by the tyre shop to make sure, I guess.

I stand corrected on the compound issue!👍

Seems like sense. 😁. As usual!

Welcome back. I was covid had got you.

Thanks, cobber. Had a bit of a downturn in life for a bit there, but I’m clawing my way back to ( relative ) normalcy.😁

[grahamfirestorm]

Just be very very careful when changing to a different size tyre,will your insurance company withdraw its cover in the event of an accident,especially a fatal one,think about it,the bike wasnt built with the wider tyres on.

I used these sizes as well. Avons, though. They are rated for the stock size rims per Avon. Theres a rim size variance on each size tire
