• RELIABLE YINXIANG OEM ENGINE：The FX140 runs a 140cc 4-stroke, oil-cooled 11 HP engine built by YINXIANG, an OEM maker producing 1,000,000+ engines a year for 29 years, so you get dependable starts and steady torque on long off-road climbs instead of stalling out.
• DUAL-PISTON HYDRAULIC DISC BRAKES ： A 210mm front dual-piston and 200mm rear hydraulic disc brake deliver confident, fade-resistant stopping on steep descents and loose dirt, while 6-position adjustable clutch and brake levers fit small to large hands for precise control.
• PRO-SPEC SUSPENSION & KNOBBY TIRES ： 4.7-inch long-travel front forks and a 12.2-inch adjustable rear shock absorb rocks, ruts and jumps, while deep knobby block-tread tires grip dirt, sand, rock and mountain trails, reducing rider fatigue on race tracks and forest paths.
• 5-SPEED MANUAL & DURABLE DRIVETRAIN ：A 1-down 4-up 5-speed manual transmission shifts smoothly for trail control, a 428 high-tensile KMC chain resists stretch and breakage under off-road torque, and a high-visibility digital display shows speed, RPM, gear, voltage and odometer at a glance.
