Key specifications
Overview
Introducing the 2007 CR&S VUN Underpowered, a unique entry into the naked bike category that embodies the spirit of cafe racers while embracing a modern aesthetic. With a name that playfully suggests a lack of power, the VUN Underpowered is anything but ordinary. Crafted by the Italian manufacturer CR&S, renowned for its bespoke motorcycles, this model stands out with its striking design and a commitment to minimalist elegance. The VUN is designed for riders who appreciate the art of motorcycling in its purest form, offering an experience that prioritizes style and agility over sheer horsepower. At the heart of the VUN Underpowered is a 652cc single-cylinder, four-stroke engine that delivers a modest yet spirited 29 horsepower at 6,000 RPM and 37 Nm of torque at 4,000 RPM. While the numbers may not scream performance, the bike’s lightweight frame (weighing in at just 135 kg) and responsive handling create a riding experience that's both engaging and accessible. The 5-speed gearbox and wet multiplate clutch allow for smooth gear transitions, making city commuting or weekend rides a sheer delight. The VUN's design encourages confident cornering, complemented by a hydraulic fork and swingarm suspension that offer 120 mm and 128 mm of travel, respectively, ensuring comfort and stability over various road conditions. The CR&S VUN Underpowered is not just about looks; it is packed with thoughtful features that enhance the riding experience. Its steel tube frame, combined with machined light alloy plates, provides both strength and a lightweight profile. The bike's fuel injection system, integrated by Walbro, ensures efficient fuel delivery, while its liquid cooling keeps the engine operating at optimal temperatures. With a fuel capacity of 14 liters, riders can enjoy longer journeys without frequent stops, all while the adjustable seat height of 800 mm accommodates a range of rider sizes, making it approachable for many enthusiasts. **
