VUN Tuned-Up

2008 CR&S VUN Tuned-Up Technical Analysis & Specification Breakdown

Positioned in CR&S's naked motorcycle lineup, the 2008 CR&S VUN Tuned-Up relies on a 652 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 67.1 HP (48.9 kW) at 7,500 rpm while maximum torque reaches 65.2 Nm (48.1 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 102.9 HP per liter and a 500 rpm working window between peak torque (7,000 rpm) and peak power (7,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the VUN Tuned-Up measures 135 kg (298 lbs) dry, translating to a power-to-weight ratio of 0.5 HP/kg (2.01 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.
