Changing sprocket, What size?

Post by LITTLE MUG » Sun Oct 10, 2010 8:30 pm

Hi,
Ive got an nc29 that I've been trying to wheelie unsucessfully for some time now so I'm thinking of changing the gearing to make it easier to get the front up. Only problem is I dont know what size sprocket i should go for,and do I change the front, rear or both? Has anyone else done this or have any useful info? Cheers

Many people do same. I'm using 14 front/42 rear. Rear from CBR900

I'm using the same as Parus. You'll need to make some adaptations to get the CBR900 rear sprocket to fit - alternatively get a 520 kit.

About £50 plus p&p, ex race chain and sprockets. Mine were as new off Graeme :peace:

Here is CBR900 SuperSprox spocket at my rear wheel

And following stud need to be done to fit this properly, because mounting holes is 12,5 against 10,5 on NC29
