MBK X-Limit SM 2007 — Specifications

In 2007, offering a 50cc supermotard with injection would have been heresy. MBK knew this, and that’s why the X-Limit SM runs on two-stroke and pure gasoline, with a Dell’Orto PHBN 16 serving as an artificial heart. Its liquid-cooled single-cylinder breathes with a compression ratio of 12:1, figures that still speak to DIY enthusiasts who like to adjust the transfer port and play with hot plugs. With 2.8 horsepower delivered at 6750 rpm and 3.3 Nm of torque, performance is far from staggering, but that’s not the point. This machine is a statement of principles: the pleasure of two wheels begins long before a full license.

The chassis displays clear intentions with a 870 mm seat height, a wheelbase of 1350 and 317 mm of ground clearance. These figures outline an aggressive posture, ready to lean. The 100/80 tires at the front and 130/70 at the rear, mounted on 17-inch rims, confirm the pure supermotard DNA. Braking, provided by two 260 and 220 mm discs, is more than sufficient for a dry weight announced at 98 kg. It’s a lightweight motorcycle, nervous in its design, which requires the rider to actively participate, to play with mass transfers and anticipate slowdowns.

The six-speed gearbox is a surprise for such a displacement; it allows the modest single-cylinder to be revved without constantly howling. The 6.5-liter tank reminds you that journeys will be short, but intense. It’s not a machine for eating up the highway; it’s a tool for transforming a dirt track into a circuit, a deserted street into a playground. Liquid cooling helps maintain a stable temperature during intense sessions, a detail that counts when pushing the small engine to its limits.

Faced with a Derbi Senda or an Aprilia RX 50 from the same era, the MBK X-Limit SM does not seek a horsepower race. It focuses on balance, mechanical accessibility, and a straightforward geometry. Its price at the time positioned it as a credible alternative for young people aiming for an A1 license, or for enthusiasts of raw sensations without electronic complexity. Today, it finds its place with the collector of two-strokes or the experienced rider seeking a simple and modifiable platform. It’s a motorcycle that doesn’t cheat; it exhales a scent of castor oil and old-fashioned freedom in an increasingly aseptic world.
