Trail Bikes 51mm 12v Stroker Crank - Z50 / XR50 / CRF50 / XR70 / CRF70

TB 51mm Stroker Crank for 12 Volt Honda 50/70

A stroker crank will give you more cc's and as they say there is no replacement for displacement. More cc's is great but they actually run different.
They pull harder and longer which means you can get some good gearing and make your bike scream.
A stroker crank in a Honda 50 or 70 is amazing, you will love it.
This crank can be used directly with any & all 12 volt engines Z50 / XR50 / CRF50 / XR70 / CRF70 with the proper piston.

It can also can be used in older 6 volt engines when combined with a newer Honda or China 12 Volt ignition and correct deck height piston.

This is the crankshaft sold in the TB Parts 108cc kits and must be used with the correct supporting modifications.
