Naraku Racing crankshaft +2mm stroke for GY6 125 / 150cc

The crankshaft is a central element in an engine, as it converts the upward and downward movement of the piston into a rotary movement and, in 4-stroke engines, also determines the valve position via the timing chain/toothed belt or similar and camshaft.

More power for your scooter? No problem!

We offer you a top quality racing crankshaft from Naraku .
This offers 2mm more stroke and can be installed without major extensions using spacers or on the timing chain. Due to the increased compression, only a stronger (or two normal) cylinder base gasket should be used.
