The new crankshaft Modellsport is designed with the latest technology's that
has been proved in the 2 stroke racing engines.

It is for application on original Zenoah engine RC230/240 and RC260/270

Made with the best material, the crankshaft can be overhauled many times,
due to the hardened crank.
With the Modellsport R1 crankshaft the engine has much better acceleration
out the corner and revs very fast. The balance has been optimised for reduce
vibrations.
The crank is fully stuffed for a higher inertial and it will also raise the
primary compression, which will result in more power increase in the higher
rpm range.
