Rieju 125 NKD 2007 — Specifications

In 2007, small displacement motorcycles weren't all destined to look like toys or scooters in disguise. The Rieju 125 NKD proved this with a certain insolence, planting its straight handlebars and stripped-down lines in a segment then rather timid. This Spanish brand, heir to a long tradition in off-road riding, applied its philosophy to the road here: a serious chassis, credible handling, and a simple and robust single-cylinder engine, all for a price that had to remain contained. It was a pragmatic, almost old-school approach, a world away from the plasticized and sanitized 125s.

The high-strength steel double-spar perimeter frame sets the tone. It’s not there to look pretty in the brochure, but to offer a rigid and precise base, a rare thing on a machine of this category at the time. The 35 mm inverted fork and the single shock confirm this orientation: it’s on a motorcycle architecture, period. The single disc brakes, front and rear, do the job without frills. With 100/80 and 130/70 tires, mounted on 17-inch rims, and a wheelbase of 1300 mm, the geometry announces road, even sporty, intentions. At 107 kg dry weight, lightness is a major asset, making each horsepower precious.

The engine is a declaration of simplicity. A 124 cc four-stroke single, air-cooled, fueled by a Mikuni VM20SS carburetor. With 14.5 horsepower, it won’t pulverize records, but its perfect squareness (bore and stroke at 54 mm) suggests a balanced character, capable of pulling without being too peaky. The five-speed gearbox and final chain drive complete a mechanically straightforward, easy to maintain, and everyday-friendly assembly. The 10-liter tank, coupled with modest consumption, promises beautiful ranges for short trips or student excursions.

The Rieju 125 NKD didn't target the experienced rider looking for a second machine for the track. It was aimed at the young license holder, the demanding city dweller, or the mechanically inclined enthusiast looking for a real motorcycle, not a compromise. It offered the authentic feeling of riding, with a reactive chassis and a natural riding position, far from uncomfortable mini-sportbikes. In the landscape of 125cc motorcycles of the time, it was an honest proposition, straight and to the point, which recalled that the pleasure of riding often begins with solid foundations and a defined character.
