250cc Dirt Bikes
The full-size petrol group: the factory's adult pit bike line at 200cc and 250cc, published with its complete specification table.
The documented 250cc group bike is built on a CB250D single-cylinder four-stroke air-cooled engine (250cc displacement in the table) with a manual wet multi-plate five-speed transmission (1-N-2-3-4-5), a central-tube high-strength steel frame, and dual-piston caliper 240mm disc brakes at both ends. The front fork is an inverted hydraulic adjustable unit with 180mm of travel; the rear shock is a 460mm non-adjustable unit with 90mm of travel. An alloy-rim and knobby-tyre option in 21/18 sizing is listed in the table's options row.
Size figures mark this as the adult end of the petrol line: 900mm seat height, 1320mm wheelbase, 325mm minimum ground clearance, 105 kg net weight, a 6.5L tank, and container loading of 32 units per 20ft and 99 per 40HQ. The same group covers the 200cc designation — the factory lists the group as its Adult Pit Bike 200cc/250cc line — so this page is also the reference for the adult pit bike shelf.

250cc petrol vs high-power electric
At the top of the dirt bike family the petrol 250cc group now sits beside the 8000W electric group, whose factory tables list higher maximum speeds (88–95 km/h) on lithium batteries. The petrol group's counters are the five-speed gearbox, the 6.5L tank's refuel-anywhere range, and a lower entry price typical of the class. Our electric vs gas dirt bike comparison sets out the full trade-off for range planning.
