A 83.8mm bore x 83.8mm stroke result in a displacement of just 297.3 cubic centimeters.
Drive[edit | edit source]
The bike has a 5-speed, manual transmission. Power was moderated via the wet multi-disc, manual.
Chassis[edit | edit source]
It came with a Michelin Trial 21 front tire and a Michelin Trial 18 rear tire. Stopping was achieved via 185mm rotor with 4-piston caliper in the front and a 160mm rotor with twin-piston caliper in the rear. The front suspension was a 38mm Paioli while the rear was equipped with a adjustable single shock, aluminum bodied, with nitrogen valve including linkage. The wheelbase was 51.42 inches (1306 mm) long.
2013 Beta Evo 300 4 Stroke[edit | edit source]
The 2014 MY Beta Evo 300 4 Stroke is a more fuel-efficient alternative to their two-stroke models in the Evo trial bike family. The two-wheeler sports a four-stroke, liquid-cooled, 299cc paired to a five-speed manual transmission with smooth and precise gear shifts thanks to a new shift drum.
On the visual side of things, the Evo has a more aggressive look, thanks to a new rear fender and side covers. Also a plus on the aesthetic side is the red frame and white plastics.
The model is available for purchase with the long-range tank/seat combo if one prefers longer trails.
2014 Beta Evo 300 4 Stroke[edit | edit source]
The 2014 MY Beta Evo 300 4-Stroke is addressed to those riders who prefer a more fuel-efficient, but still gritty, trial two-wheeler. It sports a four-stroke, liquid-cooled, 297cc, single cylinder engine mated to a sturdy five-speed, manual transmission.
A new feature on the 2014 MY is the hydro-formed frame, derived from the two-stroke model. This new frame is more rigid and allows a larger-capacity fuel tank to be mounted, all the while improving handling and making the bike narrower.
2015 Beta Evo 300 4 Stroke[edit | edit source]
The 2015 MY Beta Evo 300 4-Stroke comes as an alternative to the two-stroke models, for riders who are more concerned for the environment or who just want better gas mileage from their trial machine. The two-wheeler sports a four-stroke, liquid-cooled, 297cc, single cylinder engine and a five-speed manual transmission. Recent tweaks and improvements to the engine ensure a lean yet pretty gritty power delivery, no matter the rev range or the conditions of the trail.
