Overview

Introducing the 2009 GAS GAS SM 125 Halley, a striking example of the super motard category that perfectly balances performance, agility, and style. Known for its robust build and spirited engine, the SM 125 Halley is designed for enthusiasts who crave the thrill of city streets and twisty backroads alike. With its sharp lines and aggressive stance, this bike not only commands attention but also delivers a riding experience that is both exhilarating and accessible. As a part of GAS GAS’s lineup, it is a testament to the brand’s commitment to producing high-quality, performance-oriented motorcycles that excite riders of all levels. At the heart of the SM 125 Halley lies a lively single-cylinder, two-stroke engine with a displacement of 124 cc, delivering an impressive balance of power and responsiveness. With a bore and stroke of 54.0 x 54.5 mm, this engine offers a sweet spot in the power band, making it ideal for spirited riding. The liquid cooling system ensures that the engine maintains optimal operating temperatures, while the 6-speed gearbox allows for seamless gear transitions, enhancing the overall riding experience. Whether you're navigating through urban traffic or carving corners on a twisty road, the Halley's lightweight design, weighing in at just 99 kg (218.3 pounds), ensures that every twist of the throttle translates into immediate, thrilling acceleration. Equipped with a frame made from Deltabox rectangular profile CrMo, the SM 125 Halley boasts a sturdy yet nimble build, essential for a confident riding experience. Its suspension setup includes a 41 mm upside-down fork in the front and a one-piece aluminum swing arm with an Ohlins shock absorber in the rear, providing 255 mm and 246 mm of travel, respectively. This setup not only enhances stability but also allows for effective handling over varying terrains. Braking is equally impressive, with a single 260 mm front disc coupled with a 4-piston caliper for responsive stopping power, while the rear features a 220 mm disc, ensuring riders can confidently navigate both high-speed and low-speed scenarios. **
