Features

  • 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.
  • 90% PRE-ASSEMBLED, RIDE-READY KIT Ships 90% assembled for quick final setup, fits riders 5'4"6'2" up to 265 lbs and is built for ages 16+. Includes gloves, goggles, anti-fog spray, backpack, hydration bladder, tool kit and carry bag, backed by a 12-month core-parts warran-ty and pro tech support. For off-road use only.

  • Carburetor that comes with is non serviceable
Color: White Size: FX125-17Pro
The bike is awesome, but there’s one issue I have, I’ve only had the bike for 3 weeks and I’ve had carburetor issues. So I took the carburetor off and they make it non serviceable so you can’t work on the carburetor. They drill off the end of the screw of the carburetor. So you’re required to buy a new one instead of just being able to work on it which is an easy fix. So just take that into hand if you buy the bike, buy a replacement carburetor that you can actually service yourself so your not required to keep having to buy the non serviceable ones. ... show more

  • Great budget bike
Color: White Size: FX140-17Pro
It's actually a pretty good budget dirtbike for the price. I already have 400 miles on mine. I have had no issues other than the kickstand spring falling off. Which was my fault. Overall great bike. Highly recommend
