MADE IN SPAIN. Thanks to its new and advanced TFI injection system, it is able to perfectly emulate the sensations, response and feel of the 2-stroke carburettor engines, thanks to its innovative system of 2 Bosch Injectors differentiated for High and Low revolutions. All this results in an extraordinary instant and forceful response, combined with the smoothness and efficiency of modern fuel injection engines.
3 clearly differentiated Riding Modes as standard, to adapt the power curve to each terrain and riding style, optimising performance to the maximum:
Surgical precision on every impact and outstanding stability on any surface and adaptable to any rider and riding style.
It has a 48 mm KYB Inverted Fork, equipped with AOS (Air-Oil Separated) System and Closed Cartridge and a KYB Monoshock fully adjustable in Preload, Extension and Compression (differentiated in High and Low speed), anchored to a progressive system of Connecting Rods.
A modern electronic exhaust valve automatically manages its opening according to revs and throttle position, for instant and consistent performance at all times and in all conditions.
Equipped with a counter-rotating Balance Shaft, it improves engine stability, minimises vibration and allows the engine to turn smoothly, taking the riding experience to another level.
More precision, greater control and extraordinary sensitivity. Lighter than traditional models, this clutch provides greater sensitivity and significantly reduces fatigue even in the most demanding conditions.
