Technical Overview
2012 E-Ton Vector ST 300 Technical Analysis & Specification Breakdown
Engineered by E-Ton for the atv motorcycle segment, the 2012 E-Ton Vector ST 300 features a 287.2 cc (17.5 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 75.0 x 0.0 mm (3.0 x inches) with a 10.0:1 compression ratio.
On the scales, the Vector ST 300 measures 225 kg (496 lbs) dry. Rider ergonomics and chassis geometry center around a 890 mm (35 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,193 mm (47 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
