For the track or for the street, these kits offer the performance you have
been looking for and are pre-packaged and ready to go. Driven USA aluminum rear sprockets are machined out of 7075 T-6 aluminum by a CNC & hobbing machine,
balanced and tested for trueness. The final process is color hard anodizing for
both beauty and surface protection against corrosion. The front sprockets are
made out of case hardened chromoly steel and machined to exact dimensions, heat
treated for greater surface strength and hard anodized for protection against
corrosion. All sprockets are machined to tolerances no greater then 0.2 mm which
is less then half OEM standards. Improve both the performance
and appearance of your bike with the addition of Driven sprockets!
Kit includes a Gold 520 RK Chain, Black Front
Sprocket and Black Rear Sprocket.
