THE POWER OF TRACTION

The heart of this model is the unmistakable 297.3 cc 4-stroke engine. Designed specifically for trials, it offers exceptional torque at low revs and incredibly smooth power delivery. It allows for millimetric throttle control and superior feel, maximising grip on any terrain.

ASYMMETRICAL OPERATING SYSTEM

The right stanchion contains the spring and is dedicated to managing elastic operation; on the left is the open cartridge for hydraulic adjustment, combined with a Ø12mm hard-anodised aluminium pump rod, 2 mm larger than the previous model.

TWO MAPS

The mapping switch on the tank cover allows you to choose between two engine maps (Rain/Dry). “Rain” softens the power delivery for slippery terrain and beginners, while “Dry” unleashes all the engine torque for maximum performance.

SPECIAL FORK SETTINGS

The EVO 300 4T is equipped with a 38 mm fork with a specific hydraulic setting, designed to adapt to the different power delivery and weight distribution of the 4-stroke engine, ensuring maximum balance and precision in the front.

TOTAL CONTROL, CONSTANT TORQUE

The EVO 300 4T is a bike that teaches you to “feel” the terrain. Its progressive engine and balanced frame allow you to find grip where others cannot, overcoming obstacles with unrivalled progression and linearity. It is the perfect choice for those who prefer constant traction to throttle response.
