Nice. I think standard gearing is ok. Standard gearing is a hoot on the road - it's just I think the bike wheelieing whether you want it to or not - out of every corner on the track up to 3rd gear is going to send me insane! I think 3rd is going to be the most used gear on track and I want to be able to get 100% throttle without dealing with constant wheelies. The slight lengthening of the wheelbase going to 42 teeth, plus the longer gearing should just take the edge off 3rd. I'm sure it'll still wheelie you you sit up - 1 tooth off isn't going to turn it into a mild-mannered commuter! -1 tooth rear be interesting for some tracks. Note CG125 can be 100% throttle opened, lol. Challenge can be controlled feeding in on. Yes them wheelies some love them but if you have to steer to track line position then yeah they can be a tad challenging, lol.

I get what you're saying and it may be so for a CG125, but I could use full throttle on my my Busa from 2nd gear onwards (clearly not whilst cranksed over!) without fear of flipping, it wasn't stock (176bhp at the rear wheel) and it would kill an MT10 down a straight, the issue with the MT10 is short wheelbase and short gearing - not the fact it's not a CG125. If I can edge those two factors towards a slightly more stable setup with a simple gearing change then I'm a happy man.

Take the guesswork our fellas, try this www.gearingcommander.com/. Select YZF r1 2015, then alter the numbers to suit our bike (there isn't much to alter). Tihs will give you an idea of what gearing changes will do.

Though on the road it is a nice benefit for turn in on the tighter roads. Tracks entry lines and sight round does not need a short wheel base. What about lower bars and slide forks up yokes a tad to and rearsets may help keep weigh towards over front. But that motor does wanna wheelie as revs rise. Sounds like something half way between a MT-10 and an R1 be perfect for you. However, as you say 42 tooth rear may help. Best wishes. Keep us posted.

No worries, I am aware you are not from UK (so English is not your home language), but try this way next time someone makes a mistake "Thanks for the info, but the MT10 is on that site, I loaded it up last year", is a preferable way of pointing out the info exists.

Tihs will give you an idea of what gearing changes will do. I usually code a gearing spreadsheet for any bike I buy - this certainly makes it all a bit easier!

New chain and sprockets going on Monday, sticking with standard gearing! Nowt wrong with it in my opinion..👍🏻

I have switched to 42 rear and my opinion for what its worth, its a better ratio. I have run this both on track and roads and prefer it for all aspects of riding, based on the longer wheel base and slightly reduced wheelie tendency.

Finally got round to fitting my 1 tooth less rear sprocket, I'm quite frankly astonished at the difference it's made, I can now pin the throttle in 3rd without having to worry about wheelies, just light wriggling of the bars - I guess it has taken a chunk of the exciting character of the bike away. My main concern was to make 3rd gear usable on the track as I've got a few trackdays coming up and don't want to spend all day fighting wheelies. It means that I can also use 3rd for overtaking on the road now without losing my steering halfway past the cars! I preferred the character of the bike on stock gearing but I know it's going to be far more ridable on the track with this gearing.
