The Beta 300 EVO 4-Stroke (2026) is the refined choice for riders who prioritize smooth, linear power and constant traction over the aggressive "snap" of a 2-stroke. It is powered by a 297.3cc liquid-cooled 4-valve engine, specifically tuned to deliver high torque at low revs, making it an exceptional climbing machine for both amateur enthusiasts and technical competitors. For 2026, the bike features a significant suspension overhaul, including an asymmetrical 39mm front fork with a larger inner cartridge for better oil flow and a more progressive feel when absorbing large impacts. The 300 EVO 4T is built on a hydroformed aluminum single-wave beam frame, keeping the bike remarkably agile despite the slightly heavier 4-stroke architecture. It also includes Beta’s innovative Electronic Key, which serves as both a safety kill-switch lanyard and a coded anti-theft device. With its 5-speed transmission, BrakTec hydraulics, and a seat height of just 26 inches, this model excels in providing millimetric throttle control and a "whisper-quiet" exhaust note that allows you to "feel" the terrain more effectively than on a traditional 2-stroke.
