Elite Upgear Kit
$ 64.99
When doing a big bore kit, you need gears. Without them you are never going to take advantage of the extra power. Choose whichever set fits your needs. I suggest going for taller gears, if you do a lot of flat top speed riding, and shorter ones if you like acceleration, and stop/go.
