2010 E-Ton Viper ST Exl-150 Technical Analysis & Specification Breakdown
Positioned in E-Ton's atv motorcycle lineup, the 2010 E-Ton Viper ST Exl-150 pairs a 149.5 cc (9.1 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 57.4 x 57.8 mm (2.3 x 2.3 inches) with a 9.7:1 compression ratio.
On the scales, the Viper ST Exl-150 measures 170 kg (375 lbs) dry. Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,110 mm (43.7 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
