Description
For those who prefer higher gearing (essential to make best use of the added power from the 902 Kit) we recommend using 19 teeth at the gearbox. These sprockets can be easily fitted replacing the standard 18T sprocket on 865cc models without alteration to chain length.
PLEASE NOTE ON 2012 AND LATER MODELS THAT USE A GEARBOX SENSOR TO FEED SPEEDO DRIVE FITTING THE 19T FRONT SPROCKET WILL CAUSE THE SPEEDO TO UNDER READ AND THEREFORE REQUIRE RECALIBRATION.
THIS SPROCKET IS DESIGNED TO USE A 525 PITCH CHAIN. SOME 2015 MODELS USE A 520 PITCH CHAIN PLEASE DOUBLE CHECK YOUR CHAIN BEFORE ORDERING IF NOT SURE. YOU CAN CONVERT A BIKE WITH THE 520 CHAIN TO THE MORE DURABLE 525 BY REPLACING BOTH SPROCKETS AND THE CHAIN.
