125cc Dirt Bikes

The volume class of the petrol dirt bike line: the factory's 125/140cc four-stroke motocross group, with its specification table in full.

The 125cc class sits in the factory's 60cc–190cc band and is the first geared, full-specification step in the petrol range. The documented group bike runs a 125–140cc four-stroke engine (a 140cc/160cc option is listed in the table), a four-speed gearbox, a high-strength steel pipe frame, 14/12 wheels, front and rear disc brakes (hand brake front, foot brake rear), an upside-down front shock absorber and a built-in hydraulic rear shock.

The fit and freight figures: maximum speed listed as 60–80, maximum load capacity 150 kg, seat height 810mm (±5mm), wheelbase 1220mm, minimum ground clearance 320mm, net weight 70 kg, and loading of 63 units per 20ft container and 172 per 40HQ. This is also the class that carries the youth motocross market — the same group anchors the top of the kids and youth ladder and the starter end of the pit bike shelf.

Stepping up and down from 125cc

Below this class sits the 52cc two-stroke — lighter, automatic, and aimed at first-time riders. Above it, the 250cc group adds a five-speed gearbox, 240mm discs and a 900mm seat height for adult riders. Dealers typically stock the 125cc class as the hinge of the petrol dirt bike shelf: it is where a youth range becomes an adult range, and the table above is the reference for every claim made about it.
