hey all, don't know if this has been posted before, but would like to know how many teeth on standard rear sprocket, and does a larger sprocket give better acceleration. (just lookin for a cheap mod).
any help appreciated. ![]() |

44T for your faired bike
45T for a Naked Yes larger rear sprocket will increase acceleration & reduce top speed Alternatively std front sprocket is 15T & the opposite smaller front sprocket will increase acceleration & reduce top speed - it will have 3 times the effect, or equivalent to going up 3t on the rear. You can always do both, just watch out chain lenth, eg 14T front would have no effect ![]() HTH |

how much reduction in top speed are we talking, will it still pull 100+?

Blue worked it out as 127 revs per tooth & I reckon one more tooth on the front reduces my revs by 500 in top.
So say your top speed now is 135 at 11,000 revs 3 Teeth up on the back would be 125 at 11000 revs (but maybe the engine will have enough power to rev higher as you are going at a slower speed?) |

I read about changing the front sprocket in this months RIDE magazine, and they say it will make a considerable difference. Has anyone on the org actually done this, and is there a big difference in the pull off? would I need to do the reverse of more teeth on the rear - by shortening the chain with this mod?
I assume this mod is like putting lighter rollers in the variator of a scooter, thus giving higher revs and giving more bite? It's nice to read about things like this, but I'd prefer 'hearing it from the horses mouth' so-to-speak. Chin

Just a bit of due warning about doing this - reducing one tooth on the front sprocket greatly increases the wear on the chain, and front sprocket - and therefore the rear chainring as well.

I changed the rear sprocket to 46T......can't say I noticed a discernable difference in acceleration. However, I preferred the way the bike rides with the standard sprocket if that makes any sense. When the 46T wears out, I'll be dropping back to standard I think.
Probably everyone else on the org will disagree with me though.....horses for courses and all that ![]() |

1T up on the rear is hardly noticable! I'd go to a 14T on the front for any noticable difference, and the wear isnt that much faster than the standard 15T. I depends how well you look after your chain too.
