Positioned in Beta's trial motorcycle lineup, the 2024 Beta Evo Factory 4T 300 pairs a 297.3 cc (18.1 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 84.0 x 53.6 mm (3.3 x 2.1 inches) with a 10.3:1 compression ratio.
Rider ergonomics and chassis geometry center around a 660 mm (26 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,305 mm (51.4 in) wheelbase engineered for quick, flickable steering geometry. The 2.8-liter (0.7 US gal) fuel tank paired with a rated consumption of 3.3 L/100 km provides an estimated theoretical range of roughly 85 km (53 miles) between fill-ups.
Within MotoLibrary's Beta archive, this model family spans 2 indexed model years from 2021 to 2024, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
