Ferrari 312PB-Style Go-Kart

This go-kart was hand-built by the seller over the past year-and-a-half as an 80%-scale rendition of 1970s Ferrari 312PB race cars, and incorporates various details that arose through the model’s development. Highlights of the build include a Honda Gold Wing 1,520cc SOHC flat-six and five-speed transmission, coil-over dampers, four-wheel disc brakes, a Polaris Sportsman rear differential, staggered-diameter wheels, and fiberglass bodywork over a custom steel frame with boxed aluminum sections. The driver is provided with a padded seat, a harness, a three-spoke MOMO steering wheel, a roll bar, a rear-view mirror, a windscreen, and a fire bottle. Work in April 2026 included an oil and filter change, replacing the spark plugs, flushing the coolant, and rebuilding the carburetor. This 312PB-style go-kart is now offered in Bradenton, Florida, on a bill of sale.

The Ferrari 312PB was introduced in 1971 and later found success, winning 11 of the 12 races in the World Championship for Makes in 1972. Factory drivers included Mario Andretti, Jacky Ickx, Carlos Reutemann, Brian Redman, Clay Regazzoni, and Ronnie Peterson.

The seller fabricated the fiberglass body panels based on photographs of various iterations of 312PB race cars and produced the panels at an 80% scale of the factory cars. The bodywork is finished in red with unfinished lower panels, and features include a front spoiler, covered headlights, white tail fins, a black roll bar, air ducts, a driver’s fairing, a windscreen, taillights, dual exhaust outlets, white roundels, Shell and Chronograph Heuer logos, a “P” designation, and a raised rear-view mirror. Opening doors with pull-cord latches also feature, together with hinged rear bodywork for access to the engine.

The tubular steel frame is outfitted with aluminum box sections that incorporate 1.25-gallon fuel tanks with black fuel doors on each side, and an inspection hatch positioned on the front allows access to the foot pedals and brake fluid reservoirs. Gold-finished 10″ steel wheels are fitted up front and wear 16×7 Hoosier FSAE wet-weather tires, while the 12″ rear wheels have 22×11 Duro Scorcher tires. Braking is from Austin-Mini-specification discs up front; out back, Polaris Sportsman cross-drilled discs, hubs, and axles are fitted.

The cockpit features a single pleated seat, headrest, and side bolsters trimmed in red houndstooth cloth, as well as a four-point harness with Sabelt shoulder pads. A black microsuede-trimmed MOMO steering wheel fronts a dash with switches for fuel pump, ignition, and exterior lights, as well as gauges for water temperature, voltage, and a tachometer. A rotary switch adjacent to the choke pull is redundant. A gear shift lever is mounted on the right side ahead of a brake bias adjuster.

The water-cooled 1,520cc SOHC flat-six engine and five-speed transmission were sourced from a 1993 Honda Gold Wing motorcycle, which the seller notes had 33k miles when installed. Oil seeps are present. Aluminum radiators are fitted on each side, with a third radiator fitted atop the engine. An air box is shown fitted in the gallery below, but is not currently used.

Drive is sent to the rear wheels via a Polaris Sportsman rear differential. The kart also features coil-over dampers and rack-and-pinion steering.
