Hello, I'm just wondering if there is anyone with a small front sprocket on the 650, I'm thinking to put a smaller front sprocket to get more push in the taking off , looking for information in any side effects thanks

Many have done it, some along with a +2 rear sprocket, search a bit and you should find quite a bit of info. The thing to note is you will need a speedo healer device or your speedometer will be inaccurate.

Typical drawbacks: lower top speed in every gear, increased fuel usage, higher RPM when cruising, but for the most part people get the desired result.
