Overview

Introducing the 2008 GAS GAS SM 125 Supermotard, a spirited machine that embodies the thrill of supermoto riding. Designed for both the urban jungle and twisty backroads, the SM 125 stands out in the competitive supermotard category with its blend of lightweight agility and powerful performance. GAS GAS has crafted a reputation for producing bikes that cater to the passionate rider, and the SM 125 is no exception. Its unique combination of dirt bike DNA and street-ready features makes it an enticing choice for enthusiasts looking to conquer both off-road and on-road conditions. At the heart of the SM 125 is a robust 124cc single-cylinder, two-stroke engine, which delivers a punchy performance that will thrill even the most seasoned riders. With a bore and stroke configuration of 54.0 x 54.5 mm, this machine offers an excellent power-to-weight ratio, allowing for quick acceleration and nimble handling. The digital CDI multispark ignition ensures reliable starts and smooth power delivery, while the liquid-cooling system maintains optimal engine temperatures during spirited rides. A 6-speed gearbox paired with a multidisc hydraulically operated clutch allows riders to shift seamlessly, capitalizing on the engine’s responsive nature. Whether you're zipping through city streets or tackling winding roads, the SM 125 promises an exhilarating ride. GAS GAS has equipped the SM 125 with a host of impressive features designed to enhance both performance and comfort. The Deltabox frame, constructed from rectangular profile CR/Mo, offers exceptional rigidity and stability, boosting rider confidence. The front suspension boasts a 45 mm upside-down fork with 295 mm of travel, effectively absorbing bumps and providing a plush ride, while the one-piece aluminum swing arm at the rear ensures a balanced and responsive feel. Stopping power is provided by reliable single disc brakes—300 mm up front and 220 mm at the rear—giving riders the confidence to tackle sharp corners and sudden stops. The bike's lightweight design, tipping the scales at just 101 kg (222.7 lbs), combined with a ground clearance of 340 mm (13.4 inches), ensures an agile and responsive ride that is perfect for navigating urban environments or taking on tight trails. **
