Driven Racing EVO TECH front sprocket for Kawasaki Z125 with 420 chain.

Driven Kawasaki Z125 front sprockets are available in 13t and 14t options.


A few rules regarding gear ratios for sprockets are as follows:

  • Drop teeth on front/add teeth to rear = increased torque, increased acceleration, wheelies, racetracks with short straights
  • Add tooth on front/reduce teeth on rear = increased top end speed, open road cruising, lowers RPMs, better gas mileage, tracks with long straights
  • 1 down on the front is like adding 3 teeth on the rear
  • The bigger the rear sprocket, the lower the gearing and the faster the acceleration
