This 1986 Yamaha YZ125 is finished in red and white and powered by a 123cc two-stroke single paired with a six-speed transmission. Equipment includes a Mikuni carburetor, Yamaha Power Valve induction, an expansion-chamber exhaust system, a piggyback-reservoir monoshock, Monocross swingarm linkage, a front disc brake, a kick starter, number plates, and gold-finished rims. Acquired in 2025 by the selling dealer, a Local Partner, this YZ125 is now offered at no reserve in New York for off-road use only with a bill of sale.

The plastic bodywork is finished in red and white with red, white, and blue graphics, and set over a red-finished steel frame. Details include a red vinyl solo seat with white script, folding serrated foot pegs, front and side number plates, and high-mounted fenders. The bike is not equipped with a side stand, and the pictured rear center stand is not included in the sale.

Wire-spoke wheels with gold-finished rims measuring 21″ up front and 18″ out back and are mounted with Dunlop knobby tires. Suspension includes a 43mm leading-axle fork along with a Monocross swingarm linkage and piggyback-reservoir monoshock. Braking is handled by a cross-drilled front disc and rear drum.

The cross-braced handlebar is finished in black and wears a Renthal-branded pad as well as bright levers, black grips, and black switchgear. The YZ125 is not equipped with an odometer or other instrumentation, therefore true mileage is unknown.

The liquid-cooled 123cc two-stroke single is equipped with a kick starter, a flat-slide Mikuni carburetor, Yamaha Power Valve induction, an upswept expansion-chamber exhaust system, and twin high-mount radiators.

The engine number is shown above, and the frame VIN number JYA1LX004GA008316 is captured in the gallery.

Power is sent to the rear wheel through a six-speed transmission and a gold-finished drive chain.

The bike does not have a title or registration. It is being sold on a bill of sale only.
