With a striking design that echoes the aesthetics of larger superbikes, this model embodies the thrill of the track while being street-legal and accessible to various riders. At the heart of the GPR Racing 125 lies a robust single-cylinder, two-stroke engine with a displacement of 124.76 ccm, delivering a thrilling power-to-weight ratio.

Stopping power is equally impressive, with 300 mm front and 180 mm rear disc brakes featuring 2-piston calipers that deliver precise braking performance. Additional conveniences, like electric starting and a fuel capacity of 13 liters, ensure you can focus on the ride without distractions. Available in striking black or a bold red/grey combination, the GPR Racing 125 is as much a statement of style as it is a feat of engineering. **
