Overview:
Evo 300 4 stroke provides the rider with a whisper-quiet exhaust note, traction that only a 4 stroke can provide as well as a power delivery that is almost electric. The four-valve engine with a five speed transmission is the perfect match for those who strive for the power delivery of a thumper.
The main new feature for 2024 involves the introduction of the “Electronic Key,” which plays a dual role, combining the safety of a kill switch with a tether attached to the rider but also acts as an anti-theft device that is coded to each full-size EVO to deter theft. This new Electronic Key is a patent product and exclusive to the Beta brand.
