Product description
Crankshaft with a 52mm stroke and so-called "6 volt" flywheel shaft journal. Cylinder capacity can be increased with a larger cylinder, but also with a longer crankshaft stroke! If you now have, for example, a 51mm cylinder on your standard crankshaft, it is now 85cc. With this crankshaft it becomes 106cc. You don't need another higher cylinder! Suitable for the OT 6 volt engines, such as SS50, CD50, C50, C70, OT Dax.
