TB Parts Primary Gear eliminates the centrifugal clutch on the crankshaft to reduce rotational weight which makes your bike rev faster. This can only be used with a manual clutch kit and will make your bike full manual only. When using this gear and removing the stock clutch off of the KLX/DRZ110 crankshaft it will shed almost 8 pounds of weight! This gear will work with our TB Parts manual clutch kit or other manual clutch kits on the market.

We also have this gear listed with a side cover gasket for the complete install kit!
