EVO 2T 300 SS MY 2021

Beta launches the new Evo My 2021.
Following a path of continuous improvement and fine-tuning, the Evo 2021 has been updated with various modifications aiming to even better performance and easier use. Although competitions had been postponed due to the Covid-19 emergency, Betamotor technicians managed to keep the development activity going, working along with the factory pilots James Dabill, Benoit Bincaz, Matteo Grattarola, and Luca Petrella.
The 2-stroke version is available in four displacements: 125, 250, 300 and 300 SS. “SS” stands for “Super Smooth”. This means that thanks to additional weight on the flywheel for increased inertia and other small measures, this version is more manageable at medium-low revs if compared to the Standard version – still maintaining the racing nature at higher revs, just like her Standard sister. This makes the SS extremely easy and entertaining to ride.

SPECIAL COMPONENTS

 

Engines

Engines (except the 125 cc) feature a cylinder with a new exhaust port geometryand new timing curves. Both ofthese developments improve low-rev engine control and stabilize the power delivery, providing exceptional, stock-setting performance.

Gear selector cam

A new gear selector cam has been designed which was used in the earlier Factory models, and provides more positive shifting.
