I have a few questions. First my plans are to us kx65 forks/ brake with bbr clamps, kx 60 rear hub with extended swing arm. 1) I am looking at the stock shock TBR swing arm but Is it an extended swing arm that uses the stock length shock? 2) Is does the TBR swing arm have the anit-spin tab welded on for the kx60 drum? 3) I already have a renthal sprocket for a 60 hub but it is a 44t, What size front sprocket will keep the gearing stock? So far my parts pile include new black excel wheels, kx 65 front end w/ brakes and hub, kx60 rear hub w/ drum brakes.
