Mash Six Hundred 650

Mash Six Hundred 650 Euro 5

The Mash Six Hundred 650 represents the pinnacle of the Mash lineup — a full-sized retro roadster with the heart and soul of a classic and the performance of a modern big single. Built to evoke the charm of the 1960s, this 650 cc machine delivers the perfect balance between vintage appeal and real-world usability.

At its core is a 644 cc single-cylinder, 4-stroke, air/oil-cooled engine, producing approximately 40 hp (29 kW). With electronic fuel injection, a 5-speed gearbox, and Euro 5 compliance, it offers strong low-end torque, smooth acceleration, and dependable performance whether you’re commuting or touring.

Riding dynamics are enhanced by a telescopic front fork, twin rear shocks, and a rigid tubular steel frame that keeps handling stable and predictable. Stopping power comes from front and rear disc brakes with ABS, offering confidence in all weather conditions.

The Mash Six Hundred 650 features all the hallmarks of a true classic: spoked wheels, chrome exhaust, hand-stitched seat, and a teardrop fuel tank with polished details. The 780 mm seat height ensures comfort and accessibility for most riders, while its 182 kg weight maintains agility for a larger-capacity machine.

Every model is fully assembled, pre-inspected, and ready to ride, complete with a 2-year manufacturer warranty. We offer low-deposit finance and nationwide delivery, so you can enjoy the thrill of owning a big retro single without the hassle.

Whether you’re stepping up from a smaller bike or simply want an authentic, big-thumper classic with everyday usability, the Mash Six Hundred 650 delivers timeless design and serious performance.
