BETA EVO 300 4T 2019
BETA EVO MY 2019
Evolution in action
Beta launches the new EVO MY 2019 into the market.
The Tuscany-based bike builder's engineers have completed an intense development and technical refinement program to give the new Evo an even higher performance and reliability while increasing the fun factor and rideability.
The new Trial range incorporates all the race know-how built up by the Beta Factory Team (which, this year, has two top riders, Albert Cabestany and James Dabill), ensuring all riders, non-professional and professional alike, can count on the best available technology.
There are four 2-stroke engines: 125, 250, 300.
The 300 4T (4-stroke) engine has also been upgraded. One of the most important new features is a new throttle with a redesigned internal ramp that gives better low-rev power control. Like the 2-strokes, the 4-stroke inherits the new CDI control unit with new, dedicated mapping.
Much of the attention was directed at the chassis set-up, with a series of new features on both the 2-stroke and 4-stroke models:
• New shock absorber port geometry: now higher and more progressive;
• New shock absorber piston: increased suspension sensitivity and progression. Together with the modified plug geometry, the new piston generates decidedly more grip, making it more forgiving in the event of rider error;
• New pump on mechanical side of fork: ensures more progressive impact absorption;
• New fork oil: improves stability at high temperatures, maximizing smoothness;
• Renewed chain tensioner: adjustment range now wider while making adjustments easier;
• Rear brake caliper with brake pad anti-vibration system: maximizes precision and significantly reducing noise;
• New graphics and colors.
