The winning features of this engine are its ridability and user-friendliness - but there's no compromising on performance. Thanks to numerous finely-targeted improvements, performance has been further boosted compared to previous versions.All engines benefit from the many upgrades presented on the 2017 standard Evo models, to which the following new developments have been added:

250 cc 2 Stroke Engine:

  • Black magnesium engine main cases: provide major weight savings compared to the standard version.
  • Titanium exhaust manifold: boosts performance significantly while cutting weight.
  • Ignition mapping: specifically tuned for enhanced ridability and better throttle response.
  • New silencer: which increases performance with respect to the standard version.
  • Profiled clutch discs: maintain clutch precision and control even under the most extreme conditions.

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.
