Trail / Enduro Dirt Bike · 250CC
YKF-1 250CC Trail Dirt Bike
Real off-road geometry on a proven CB250 platform. Built for entry-level trail dealers and emerging markets that need a bike that’s easy to ride, easy to fix, and easy to move by the container.
Why YKF-1
Three reasons it sells
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.
Simple to service, anywhere
Air-cooled single, PE28 carburetor and the proven CB250 platform. No EFI service barrier and parts available worldwide — ready for markets with limited fuel quality or workshop support.
Container economics
Shipped SKD, 99 units per 40HQ. Tiered wholesale pricing drops up to 33%, leaving real margin for your channel.
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.
