Technical Overview
2010 CR&S VUN Depowered Road Technical Analysis & Specification Breakdown
Built around CR&S's naked motorcycle platform, the 2010 CR&S VUN Depowered Road utilizes a 652 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 29 HP (21.2 kW) while maximum torque reaches 37 Nm (27.3 lb-ft), transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 44.5 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the VUN Depowered Road measures 135 kg (298 lbs) dry, translating to a power-to-weight ratio of 0.21 HP/kg (4.66 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,368 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
