diff. tranny gears for 06' wr450

[millerswrsupermoto]

Anyone at all ever changed the individual transmission gears. Ive looked into it but i dont know the countershaft ratio's, or anyone who makes different gears. the only reason I need them is Im maxed out on the sprocket sizes 16 front 40 back, and still enough motor for more speed.

id check out ballards. send them some emails
i believe they desert/enduro race WR's

no idea how u got a 16 on there without it eating ur swing arm :O

im fairly certain there was a smaller rear sprocket than 40
maybe a 39?? or something

I have a 37 tooth rear on my YZ450... thinking of going up from 15 to 16 on the front to get another 10mph... but I'm worried about swingarm interference too...

The rear is from Sprocket Specialists

07 on yamaha changed the primary gear ratio in the wr's. Maby look into that. Have you tried sprocket specialists?

thanks guy's for the info and the 16 tooth sprocket did knotch out my swingarm.
