Model Highlights
NEW TFI INJECTION ENGINE
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.
THREE POWER MAPS
3 clearly differentiated Riding Modes as standard, to adapt the power curve to each terrain and riding style, optimizing performance to the maximum: Race Mode (maximum power to feel like a real racer in the chrono), Forest Mode (control and power in equal parts to enjoy any terrain) Wet Mode (smooth and progressive delivery, ideal for low grip conditions).
ELECTRONIC EXHAUST VALVE
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.
BALANCE SHAFT
Equipped with a counter-rotating Balance Shaft, it improves engine stability, minimizes vibration and allows the engine to turn smoothly, taking the riding experience to another level.
DIAPHRAGM CLUTCH
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.
KYB SUSPENSION
Surgical precision at every impact and outstanding stability on any surface, adaptable to any rider and riding style.
It features a 48 mm KYB Inverted Fork, equipped with AOS (Air-Oil Separated) System and Closed Cartridge with black anodized DLC antifriction treatment, and a KYB Monoshock fully adjustable in Preload, Rebound and Compression (differentiated in High and Low speed), anchored to a progressive linkage system.
