01

A real off-road chassis

21″ / 18″ wheels, 320 mm of ground clearance and a 900 mm adjustable inverted fork — genuine trail geometry, not styling that only looks the part.

Powertrain

Proven 250cc single

The YKF-1 runs a 250cc air-cooled 4-stroke single (CB250D-G / 165FMM platform) producing 12 kW @ 7,000 rpm and 17.5 N·m @ 5,500 rpm, paired with an international 5-speed gearbox and #520 chain drive. Electric and kick start come standard for reliable cold starts and field backup. A mature platform means consistent build quality and a global service and parts network — the low-headache factor dealers and fleets value most.
