Dirt Bike – 6-Speed Manual, Electric Start, 142 kg – High-Performance Off-Road Machine
Unleash your off-road potential with the ZFYC 271cc Dirt Bike—a purpose-built machine engineered for riders who demand power, precision, and durability on the toughest terrain. Whether you're tearing through motocross tracks, conquering mountain trails, or exploring backcountry routes, this bike delivers the performance you need to push your limits.
At its core beats a vertical single-cylinder, air-cooled 271.3 cc engine producing 16 kW of maximum power at 8500 rpm and 22 N·m of peak torque at 6500 rpm. The 9.29:1 compression ratio strikes the perfect balance between responsive throttle and long-term reliability, giving you confidence in every situation.
The 6-speed constant mesh transmission puts you in complete control across varying terrain. Carefully spaced gear ratios—from 1st at 2.583 (31/12) to 6th at 0.857 (18/21)—allow for technical crawling in the tight stuff and stretched-out legs on open sections. A primary drive ratio of 3.09 (68/22) paired with a final drive ratio of 3.02 (13/43) ensures power is delivered efficiently to the ground through the chain drive system.
Chassis geometry is dialed for aggressive off-road riding. The hydraulic disc front fork soaks up impacts, while the single rear shock absorber maintains traction through whoops and rock gardens. With 350 mm of ground clearance measured at the engine, you'll glide over logs and boulders that would stop lesser machines. The 1400 mm wheelbase provides high-speed stability without sacrificing nimble handling in tight corners.
Stopping power comes from a front disc brake paired with a rear drum brake—a combination that delivers reliable deceleration in muddy, dusty, or wet conditions. Roll on 4.6-17 front and 5.1-17 rear deep-tooth off-road tires mounted on standard iron mesh wheels, providing aggressive traction across loose dirt, gravel, and hard-packed surfaces.
Standing 2400 mm long, 850 mm wide, and 1200 mm tall, the ZFYC dirt bike commands attention. The 1000 mm seat height places experienced riders in an optimal standing position for technical sections, offering excellent visibility and control. An aluminum rear grab handle paired with a small iron shelf adds practical utility for hauling essential gear.
Weighing 142 kg ready to ride with a 150 kg maximum load capacity, this bike offers an excellent power-to-weight ratio for aggressive riding. The 11 L fuel tank provides ample range for full days of exploration, while top speed reaches 115 km/h—enough for fast fire roads and connecting trails. Climbing ability reaches an impressive 28°, so steep ascents won't slow your momentum.
Full LED lighting ensures visibility in low-light conditions—the headlight delivers 5W of efficient illumination, while the taillight combines 5W running and 21W brake functions. Front and rear LED indicators consume minimal power while keeping you visible to other riders. A maintenance-free 12V 5Ah battery delivers reliable starts, with an optional charger available for convenience.
The ZFYC 271cc Dirt Bike isn't just another off-road machine—it's your ticket to uncharted territory.
