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 balancer 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.
