VUN

2008 CR&S VUN Technical Analysis & Specification Breakdown

Engineered by CR&S for the naked motorcycle segment, the 2008 CR&S VUN pairs a 652 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 54 HP (39.4 kW) at 7,000 rpm while maximum torque reaches 58.9 Nm (43.4 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 82.8 HP per liter and a 2,000 rpm working window between peak torque (5,000 rpm) and peak power (7,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the VUN measures 135 kg (298 lbs) dry, translating to a power-to-weight ratio of 0.4 HP/kg (2.5 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 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 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
