Key specifications
Overview
Introducing the 2008 CR&S VUN Underpowerd, a striking naked bike that embodies the spirit of Italian craftsmanship and design. Positioned for those who appreciate the blend of retro aesthetics and modern engineering, the VUN Underpowerd captures the essence of cafe racers and superbikes, as suggested by its name. The bike stands out in the crowded market of naked bikes, designed for riders seeking an authentic and engaging riding experience with a unique flair that only CR&S can deliver. At the heart of the VUN Underpowerd is a spirited 652cc single-cylinder, four-stroke engine that produces 29 horsepower at 6,000 RPM. While it may not be the most powerful option on the market, the bike compensates with a robust torque delivery of 37 Nm at 4,000 RPM, ensuring that riders experience a lively performance in urban settings and winding backroads alike. The liquid-cooled engine is paired with a 5-speed gearbox, providing smooth gear transitions and a responsive power delivery that enhances the overall ride. The lightweight design of just 135 kg (297.6 lbs) and a power-to-weight ratio of 0.2148 HP/kg further contribute to the bike's agility, making it an exhilarating companion for both new riders and seasoned enthusiasts. The CR&S VUN Underpowerd is not just about performance; it’s packed with features that enhance the riding experience. The bike boasts a durable steel tube frame complemented by machined light alloy plates, ensuring both strength and a lightweight feel. The front hydraulic fork and rear swingarm suspension offer 120 mm and 128 mm of travel respectively, providing comfort and stability on various terrains. The single disc brakes, with a 320 mm diameter up front and 220 mm at the rear, deliver reliable stopping power while maintaining the minimalist aesthetic that defines naked bikes. With a seat height of 800 mm, riders of varying heights can enjoy the VUN Underpowerd's commanding riding position. **
