Vortex Engine ROK DVS

The Rok DVS engine offers great and unique driving sensations, making the fun and challenge experience greater and higher.
Only a big manufacturer, with many years of successful experience, Vortex is able to realise this project.

The engine has the following features:
Single-cylinder 2 stroke engine, displacement 125cc, reed valve intake in the crankcase. Liquid-cooled through external pump (not supplied in the kit). It is also equipped with a balance shaft that reduces vibrations and power valve that improves performance and driveability.

The engine comes in a complete kit with IBEA branded ROK DVS Ø 24mm carburettor, Arrow intake silencer, exhaust with integrated exhaust silencer. Rok DVS engine does not require special efforts to start, thanks to the decompression push-to-start valve on the head. This system, combined with other technical solutions, keeps the Rok DVS faithful to the philosophy that has made the success of the Rok Cup: high performance, easy to manage and easy to use.
