Positioned in CR&S's naked motorcycle lineup, the 2012 CR&S VUN VR2 Road Underpowered features a 652 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 29 HP (21.2 kW) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. 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 VR2 Road Underpowered measures 152 kg (335 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.24 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, while factory top speed is listed at 180 km/h (112 mph).
