Technical Changes;

Cylinder Head;

Unique DOHC design; titanium valves of 31 mm for the intake, 26.5 mm for the exhaust. DLC coated finger levers design permits a 11 mm valve stroke for maximal breathing, top performance and power band up to 13,400 rpm.

Cam Cover;

Easy access to valve shims through inclined magnesium cam cover; separate cam housing; short timing chain with a hydraulic chain tensioner.

Valve Trai;

Intermediate gear above the camshaft drives water pump and the tim-ing chain. Chain length can be reduced; hydraulic chain tensioner.

Crank Shaft;

Minimum width between bearings for stiffer crank shaft; optimized balancing means no counter balance shaft is needed.

Crank Case;

A strong oil pump in a sealed crank case with a compensation port of just 1 mm sucks the oil out of the crank case and creates a depression supporting the piston work for an optimal engine response.

Carburettor;

Latest 39 mm KEIHIN FCR-MX flat-slide carburettor; adjustable accelerator pump and remote hot start button on the handle bar.

Clutch;

Magura hydraulic clutch.
