Pitster Pro MXR 155 2022 — Specifications

This is an object that in itself summarizes a whole philosophy of two-wheeled vehicles. The Pitster Pro MXR 155 doesn’t seek to impress with an overloaded technical specification sheet; rather, it displays its pragmatism as a banner. Its 155 cc four-stroke single-cylinder engine, air-cooled and fueled by a simple carburetor, is a declaration of independence. With a square bore and stroke and a compression ratio contained to 9.2:1, this engine is designed for robustness and ease of adjustment, not for power records. Its 13.5 horsepower is more than enough to animate its 65.5 kg dry weight with a smile.

The chassis reinforces this impression of raw efficiency. The chromoly cradle frame, the 1130 mm wheelbase, and the generous 216 mm ground clearance define a geometry that forgives errors and encourages bold learning. The suspension, a telescopic hydraulic fork and a preload-adjustable mono-shock, are basic elements but perfectly suited to the jumps and shocks of varied terrain. We are far from custom tuning for a sterile track; we are in the realm of the functional and the sturdy.

This approach is also reflected in the details. The four-speed transmission and a seat height of 813 mm speak to a specific audience: those who want an accessible motorcycle, easy to take in hand, where immediate pleasure takes precedence over abstract technology. The single disc brakes, the 14 and 12 inch tires, the 3.8 liter tank, everything is sized for intense but unpretentious sessions. It is a machine that assumes its status as a pure leisure product, free from road homologation constraints.

The Pitster Pro MXR 155 will never rival a KTM SX 125 or a Yamaha YZ125 on a national circuit. And that’s just fine. It finds its place in the mushroom of private tracks, improvised playgrounds, or for first experiences in amateur competition. It is aimed at the rider who wants a lightweight, reliable motorcycle, easy to maintain and repair, without superfluous electronics. It’s a return to the roots of riding, where feeling is paramount over assistance, and where every gram of dirt on the frame tells a story of simple pleasure.
