WK Colt 50 2021 — Specifications

When we think of 50cc engines, we often picture plastic scooters or underpowered mopeds. The WK Colt 50, however, takes a different path, planting a trellis frame and inverted suspension in a territory usually dominated by bare-bones economy. This little machine displays clear intentions from the first glance: to look like a real motorcycle, even when its displacement is counted in cubic centimeters.

Its 49.2cc four-stroke single-cylinder engine, fed by a simple carburetor and air-cooled, isn't going to shatter any records. The 3 horsepower at 6000 rpm and the 3.4 Nm of torque, achieved at the same engine speed, are figures that align with AM license legislation. They ensure a top speed limited to 45 km/h, a necessary requirement for this segment. The bore and stroke, nearly square at 39 x 41.4 mm, promise a bit of suppleness. The four-speed gearbox and final chain drive complete a simple and robust mechanical assembly, designed for learning and short trips.

It’s on its chassis that the Colt 50 distinguishes itself. A trellis-style tubular frame, an inverted telescopic fork at the front, and a mono-shock rear suspension give it a much more serious appearance than a simple moped. With a seat height of 76 cm and a wheelbase of 1210 mm, it offers a natural and reassuring riding position for a young audience. The braking, provided by a simple disc at each wheel, is sized for urban use without surprises. The 12 liters of the tank suggest a good range for such modest consumption.

Facing competitors like the Derbi Senda or the Aprilia RX 50, often more oriented towards a motocross style, the WK Colt 50 plays the all-rounder card. It’s neither a true trail bike nor a pure sportbike, but an urban hybrid with a big-bike look. It explicitly targets the teenager who wants a first motorcycle worthy of the name, or the adult looking for a minimalist and economical vehicle for the city. It’s an initiation motorcycle that doesn’t preach, a machine that allows you to discover the basics of riding on equipment that doesn’t blush in the face of larger models.
