YCF BIGY 150 MX 2026 Factory 26-BIGYF-150-STD

YCF BIGY 150E MX Factory – Premium Big Wheel Pit Bike with Factory Racing Components

The YCF BIGY 150E MX Factory is a premium big wheel pit bike designed for riders who demand maximum stability, professional-grade equipment, and uncompromising off-road performance. Featuring a 17/14-inch wheel setup, the powerful MOTEUR150-2 YX KLX Type engine, and numerous factory racing components, it is perfectly suited for training, recreational riding, and demanding motocross tracks.

Power comes from the reliable air-cooled MOTEUR150-2 YX KLX Type single-cylinder 4-stroke engine with 150 cc displacement and 2 valves. Combined with the large NIBBI PE28SP Racing carburetor, it delivers excellent throttle response, strong acceleration, and smooth power delivery throughout the rev range.

Power is transferred through a precise 4-speed gearbox (N-1-2-3-4). A new aluminum kick starter, stainless steel exhaust header, extra-wide stainless steel footpegs, and an aluminum rear brake lever further emphasize the professional Factory specification.

The racing exhaust system features a 94 dB silencer with a quick-removable quiet insert, providing maximum performance while keeping noise levels under control.

The chassis has been developed for demanding riders. The ZL upside-down front fork with 33 mm fork tubes offers fully adjustable compression and rebound damping and measures 800 mm in length for exceptional handling and front-end control. At the rear, the fully adjustable 355 mm shock absorber, combined with the aluminum mono swingarm, delivers outstanding traction and stability.

The reinforced BIGY frame with a newly designed airbox improves chassis rigidity while optimizing airflow to the engine. Premium components such as 7116 aluminum rims, CNC-machined aluminum wheel hubs, reinforced 4 mm spokes, and a hydraulic disc braking system complete this factory-level package.

With its 17-inch front wheel and 14-inch rear wheel, the YCF BIGY 150E MX Factory offers increased ground clearance, superior stability, and excellent rider comfort—making it the ideal choice for taller riders and demanding off-road conditions.
