    Anyone tried changing to -1 front and +2 rear sprockets on D600 '03? Going to bring her to mondello next month and thought this might help with acceleration as she's a bit sluggish pulling in lower revs. Cheers.

    Yeah I'll never be flat out in 6th gear at mondello so I was applying the same logic i.e. better acceleration with the compromise at the top end. Cheers for the answer.

    I would suggest not going smaller on the front unless you keep a very close eye on the chain slipper. They can be known to wreck the swing arm with standard gearing.

    Hi all,
    General tip, the front sprocket on most motorcycles is usually somewhere between 1/2 to 1/3 the number of teeth on the rear sprocket, so to change the gearing via the rear sprocket 3 or 4 teeth equals one on the front ! So doing one or two up or down on the rear sprocket does as little as 1 or 2 hundred rpms for the same road speeds in same gear ( top is usually where we asses) so front for major changes and rear for fine tuning !!!

    Cheers capt.

    Also going down on the front sprocket gives the chain a harder life as it's turning round a smaller radius....

    Hi Jody, sorry mate but I just can't let this pass. The difference in the amount of bend the chain would have to contend with is absolutely miniscule. We're not talking about going from an 18T to an 8T you know.

    Did I say 1 tooth less gives it 1/2 it's life ?

    No

    Does decreasing front sprocket size decreases chain life

    Yes (Even if by miniscule amounts)

    Did I say by how much

    No

    It was a general statement for if someone reads this post and decides I want loads of change and goes down 2/3/4 or whatever...

    If you could post at what size it would make a noticable difference that would help us all out for future reference :D

    If you go one less on the front the chain will eat through the slipper and gouge your swing arm over time. Happened on mine. Luckily I caught it quick and went standard again and replaced slipper. FYI.
