OK-N Simplicity of design

There is nothing superfluous in an OK-N engine. A 125cc, water-cooled, two-stroke, single-cylinder engine with a direct chain drive on the rear axle is as simple as it gets. The elimination of the clutch, electric starter, battery and electrical wiring contributes to the overall weight reduction and increases reliability, in parallel with the limitation of the maximum engine speed to 15,000 rpm. Six major competition engine manufacturers have now responded to the call by homologating their engines to ensure healthy commercial competition for the benefit of competitors.
