Description
2026 Beta EVO 300 4-Stroke
Trials riding is a proven foundation for improving performance across all on-road and off-road disciplines, making a trials motorcycle an ideal addition to any rider's garage. Because the sport is quiet and low-impact, it can be enjoyed by riders of all ages in a wide variety of settings. Trials offers a customizable level of challenge: you can enjoy a casual afternoon play-riding in a confined space with friends or enter a local competition and choose a skill class tailored for a more structured, competitive experience. As Beta transitions to the all-new Sincro line of trial motorcycles, the Evo line lives on with the proven Evo 300 4-stroke.
For those who like thumpers, the Evo 300 4-stroke is the bike of choice. Over 8 lbs. lighter than the other brands' 4-stroke, as well as a tighter turning radius, the Evo 300 4-stroke is known for being a more gentle bike to ride while also being "whisper-quiet". The bulletproof engine design is easy to work on and will provide years of trial fun!
Features May Include
Hydro-Formed Aluminum Frame w/ Built-in Fuel Cell: Strong and rigid, providing the perfect rider feedback while offering the tightest turning radius in the industry. The rear swing-arm is also made from hydro-formed aluminum.
Tubeless Rear Tire: Provides sidewall flex while running very low tire pressures for added grip. Turn-buckle spoke nipples eliminate the rim strip for easier tire changes.
Electronic key: The key is composed of two parts: one part remains fastened to the bike's handlebars, while the other is magnetic (worn by the rider with a cord around their wrist), activating a mechanism in the event they are disconnected, functioning as a “Kill-Switch”. Unlike a normal kill switch, the new electronic key also incorporates an anti-theft function, preventing the bike from being started when disconnected, thanks to coding that uniquely links the bike to the key, protecting against theft of the vehicle when it is left unattended.
Plastic and Airbox: Minimal plastic pieces to reduce weight, including a formed tank cover that provides the proper routing of all cables and wires. The one-piece rear fender has an access lid for a quick air filter change.
