my triumph daytona has a 17 inch rear wheel it should be an 18 inch when built
should i have one tooth smaller sproket on the rear to compensate for the smaller wheel any body know ?
the reason im asking about this topic is because my bike dont seem as quick as i thought it would be
maybe im just use to going to quick i dont know but thought id ask ?
the bigger the rear sprocket the faster it wll pull off.......but you will lose top end, smaller rear sprocket will give you more top end but less accelaration.
wn really depends on what you want out of the bike? top speed or grunt?maybe the gearbox sprocket needs a tooth down or maybe up,up to u really,but the triumph is pretty dam quick anyway isnt it?good luck with your findings,edd
Depends on gearing Moon
Look at a push bike the smaller the back cog or bigger the front cog the faster top end but slower acceleration.
bigger wheels will be faster in a straight line but harder to steer
If the wheel is smaller than standard, isn't the gearing effectively lowered ? Therefore you'll need a smaller rear sprocket to raise it back to standard again. Not sure by how many teeth tho.
p.s. You a member on TriumphTorque, someone there's bound to know ?

It will make the trail slightly longer but fractionly shorten distance between tyre contact points. which would probably cancel each other out. was the sprocket the original for the bike or a smaller one to change the gearing for the smaller wheel.
I see no advantage in putting a smaller back wheel in unless your a short arse. surely you'd put one in the front as well.
Changing to a smaller rear wheel will reduce top speed so smaller rear sprocket will return its original speed, its about 1.05 less that you need so just drop one tooth and its going to be fine.
If the rear spindle has not moved then the wheel base will be constant but it will interfere with the rake and trail of the bike and the overall contact of the tyres, meaning lowering the rear will make the bike steer a little slower and feel a little vague the faster you ride, to compensate lowering the front will help. Caution this might have already been done.
It's a bit like having a heavy pillion and luggage it screws up the handling a little.
