Introducing the 2001 Hyosung GF 125, a spirited naked bike that blends simplicity with a touch of style, perfect for urban commuting and beginner riders alike. As a part of Hyosung’s lineup, this lightweight motorcycle positions itself as an approachable entry point into the world of two-wheeled thrills. With its minimalist design and nimble handling, the GF 125 is designed to navigate city streets and winding roads with ease, making it a versatile choice for those looking to experience the joys of motorcycling without overwhelming power or complexity. At the heart of the GF 125 is a lively single-cylinder, four-stroke engine with a displacement of 125cc that delivers a robust 13.7 horsepower at 8600 RPM. This power output, coupled with 11 Nm of torque available at 7500 RPM, allows the bike to reach a respectable top speed of 103 km/h (64 mph). Riders will appreciate the bike's smooth acceleration and responsive throttle, making it ideal for both city traffic and weekend rides.

The front and rear brakes utilize single discs, with a 240 mm front diameter ensuring reliable stopping power. The bike’s suspension setup includes 130 mm of front travel and 91 mm at the rear, striking a balance between comfort and agility. The 13.7-litre fuel tank provides ample range for daily rides, while the seat height of 788 mm offers a low and accessible ride for a wide range of riders. Furthermore, the air-cooled engine and carburettor fuel system reflect a practical approach to maintenance, perfect for those who value ease of ownership. **
