The process is pretty easy. Its just making sure everything fits.
The fork width is around 11", so keep that is mind when selecting bars
The diameter needs to be 1" for the mounts and grips to fit
if you have an 07+ C50, you will need longer cables if you go past 12". 12" need cable re-routing. 10" is fine. If you have an older model, you wont need to re-route cables with 12" apes, but will still need longer cables if you go up more than 12".
Allen wrenches and wd-40 and you will get it done in less than 30 minutes.
