YKF-BD 650 650CC 4WD ATV | Powerful 4×4 Off-Road Quad
650cc atv for wholesale buyers, the YKF-BD 650 is the most powerful ATV in the BD series, a 650cc 4×4 quad producing 30 kW at 4500 rpm through a water-cooled 4-stroke engine, CVT (L-H-N-R) shaft drive, and 4WD, with a 95 km/h top speed that matches the BD 500. Sharing the same 25×6-12 / 28×8-12 tires, 20-liter tank, disc brakes, and 375 kg, 2000x1150x860 mm chassis as the BD 500, the 650 steps up with more low-end torque for towing and heavy trail use.

YKF-BD 650
650cc water-cooled EFI engine. Full-time 4WD. Front differential lock. Up to 95 km/h. The BD 650 is built for riders who push hard — on trails, dunes, hillsides, and everything in between.
650cc EFI — More Displacement, More Confidence
A bigger engine changes how you ride. The BD 650’s 650cc water-cooled single delivers strong mid-range pull and a 95 km/h top end — power that keeps up when the terrain demands it.
Electronic Fuel Injection for Consistent Power
EFI keeps the engine responsive across altitude, temperature, and throttle position. Whether you’re launching off a dune, crawling through rock, or holding a fast trail pace, the power delivery stays predictable and sharp — no flat spots, no hesitation.
4WD, Shaft Drive, Front Diff Lock — Traction Where It Counts
The BD 650’s drivetrain is engineered for riders who don’t avoid the hard lines. Four-wheel drive, a sealed shaft final drive, and a front differential lock give you mechanical grip when the ground fights back.
Front Differential Lock: Standard, Not Optional
Most ATVs in this class make you pay extra for a front diff lock. On the BD 650, it’s included. Engage it when one wheel loses contact — muddy switchbacks, off-camber rock faces, rutted trails — and both front wheels pull together. That’s the difference between getting through and getting stuck.
Suspension, Brakes & Tires Built for Off-Road Punishment
Long suspension travel absorbs the hits. Dual-piston disc brakes keep control when speed builds. Aggressive tire sizing bites into loose and broken ground. Every component in this package is spec’d for sport riding, not pavement.
180mm Front / 200mm Rear — Independent Double A-Arm
That extra 20mm of rear travel isn’t an accident — it’s where the chassis absorbs the big hits so you don’t have to. Oil-gas hybrid shocks stay composed through repeated impacts, keeping the wheels planted and the rider in control even when the trail turns rough.
Two Versions. One Clear Step Up from Mid-Class.
The Standard version gives you everything you need to ride hard. The EPS version adds electric power steering for reduced fatigue on technical terrain — an upgrade that matters when rides get long and trails get loose. Both versions come with a front winch and rear hook included.
More displacement means stronger acceleration out of corners, better top-end on open terrain, and headroom when you need to push harder.
A $150 spread between versions makes the EPS upgrade an easy conversation — and easy justification for riders who spend serious time in the saddle.
The electric winch comes standard — useful when a trail gets the better of you, and reassuring to know it’s there before you head out.
Complete dimensional data, packaging weights, and two-version lineup make stocking, listing, and presenting the BD 650 straightforward for any dealer or distributor.
