40mm LONG STROKE Crankshaft Crank -66/80cc Motorized Bicycle 2 Stroke – RUNWELL!
40mm Long Stroke Crankshaft Crank by Runwell
Official Runwell PK80 crank. No markings on the con rod means it’s real!
This crank ONLY accepts Type A pistons. This is a piston with a LOW wrist pin location. ZEDA’s and GT5’s use a Type B piston – these will not work.
Big, Fat cranks for type A pistons and lots of power! Some minor blemishes and scratches are possible on these. We also recommend that you clean it up thoroughly before installing it.
