    Changes to the chassis are shared on all the new models – 2 Stroke and 4 Stroke – and can be summed up as follows:

    • New fork compression adjustment: for the first time - in addition to rebound damping adjustment via a manual knob - compression can now be adjusted via an adjustment screw, positioned on the left at the bottom of the fork leg, allowing riders to personalize compression to suit individual riding styles.
    • New black anodized triple clamp: ensures greater lightness and rigidity.
    • New rear suspension with longer wheelbase and shock adjustment of both compression and rebound.
    • New rear linkage ratios: more sensitive and progressive, ensuing better traction and greater thrust in front of high obstacles.
    • Lanyard-type kill switch, for safety in case of a fall.
    • Black anodized bar end plugs, to protect grips and ensure proper, long-lasting throttle operation.
    • Black anodized engine oil plugs.
    • Black anodized chain adjusters.
    • Foot pegs, machined from solid, non-slip steel, ensure maximum riding grip even under the most extreme conditions as well as a significant weight reduction.
    • Racing brake discs deliver more powerful braking, weight savings and a more aggressive look.
    • BrakTec brake and clutch pumps for improved brake feel.
    • Michelin X-Light tires, lighter with even more grip.
    • Red combustion chamber cover.
    • New Factory graphics.
