I get lost no matter what.  I'm always lookng for the 0th and highest+1 gear.  I do it on my 6 speed Honda and my Enfield.

Indy,  glad to see I'm not alone. I usually end up pulling the clutch in and flicking my toe up to find nothing at least a couple of times a week. Lol!  Mostly I raise my toe up and can feel if there is another gear left in there.

Actually this Indian review talks abut a 6 speed Enfield but I am pretty sure its just a typo ...

If you really wanted to get finicky with final ratios on the 5 speeds you could fit an 18/19 tooth front and then also fit a rear drum with extra teeth (you can get more teeth just cannot go smaller) to fine tune it.

Lot of mucking about for minimal benefit though.

[SimonT]

totally agree.... after doing a few highway trips recently... man the bike revs sitting on 110 km/h....

[Chiefharlock]

Yeah it does!  On Monday I was pulling 70 to just over 75mph on I-44 trying to make it to a rally point with a couple of fellow riders.  a longer 5th gear or a 6th gear would have been very nice...

 If Royal Enfield would like to throw something together for testing, I would be more than happy to do well documented test riding with it out here on all these stretches of highway here in Missouri    I am a maintenance technician after all

Call me stupid!  I just don't understand.  It doesn't matter if you have a 10 speed transmission or a 4 speed, the final drive is still 1:1, you need to change the sprockets to get more top speed, then you might loose some low end power.  These are just 500cc bikes if you really want to go fast, get a 1,000cc rocket.   

Hopefully someone with more knowledge than me will come along and straighten me out.

It's not so much about going super fast as it is just cruising at a slightly lower RPM when it is necessary that you be out on the highway.

[Land Surveyor]

Just put an 18 tooth sprocket on it. That would have the same effect.

That's the simpler solution.

I would disagree that the engine characteristics won't work well with a 6th gear, though.

Harleys don't rev very high and have high torque/low HP engines and have had 6-speed overdrives for some time now.

[PAndy]

I think just the fact that you can be cruising on the highway and try to shift up when you are in 5th already shows that an overdrive 6th gear would be beneficial.  The only time I  feel like I don't have enough power on the highway is at high revs when the torque drops off.  If there were a 6th gear or maybe stretch the 5 gears out and make 5th an overdrive gear, it would be easier to stay in that high torque band at lower revs.

I don't want to go much faster than 70-75, but I'd like to do it at lower revs.

Just my opinion.  But I think an overdrive gear would make this bike incredible.  I also do a lot of highway driving, off the highway the gearing is just where it should be.

Exactly!

spot on.

Has anyone ever put in a sprocket with 19 teeth in a C5?  ScooterBob? Ice?

[barenekd]

The bike as geared will theoretically do 93 at 5500 rpm. Good luck on getting it there. Putting a one tooth larger sprocket on it would raise the theoretical top speed to 98. However in reality you may LOSE a bit of you 83 mph top speed doing that because you aren't as high up in the power band. the thing you are lacking with this bike, my friends, is horsepower. All the gearing changes in the world aren't going to make it goo much faster, actually if you geared down one tooth you may pick up a couple of MPH because you are working in a higher RPM/power range.
If you want to go faster on a Royal Enfield, your only choice is to hot rod the engine. Build a 535 and add cams and more carburetion, better exhaust, etc. The gearing changes ain't gonna cut it, guys.
