Dropping One Tooth at the Front

Hi Guys
Has anyone had any experience of fitting a one tooth smaller sprocket on the gearbox output shaft.
I have a 96 rrt, according to my calcs it should drop the ratio by about 5%.
I know in principal it would be ok but just wanted some advice from someone who has done it.

Cheers

Sean

Re: Dropping One Tooth at the Front

Should be ok! You will move the rear axle back a bit to get the right chain slack.

Re: Dropping One Tooth at the Front

I did and am happy with the results. There is a noticeable difference upon acceleration.

Re: Dropping One Tooth at the Front

FYI, That is about = to +3 on the rear sprocket. If you plan on chaning the whole setup in the future, you can adjust accordingly.

Re: Dropping One Tooth at the Front

Cheers Bob, I may end up going up 2 on the back with a Renthal alloy sprocket.

Re: Dropping One Tooth at the Front

Be aware, with the stock chain you might not have enough tire/swingarm clearance.

Re: Dropping One Tooth at the Front

Nice improvement -1f.....quicker acceleration and you really wont loose much if any in the way of top speed as the bike will then pull redline in 6th gear..net increase of 1200 rpm's or so

Re: Dropping One Tooth at the Front

Don't forget about the need to recalibrate the speedometer.
