This 1965 Rupp Grand Prix go-kart was purchased by the current owner in 2023 and was subsequently refurbished. Work included powder-coating the tubular steel frame in metallic red paint, re-chroming hardware, and rebuilding the twin McCulloch MC-91 two-stroke singles. Equipment includes centrifugal Hortsman Rev-Grip dry clutches linked with chain-driven sprockets, 5″ turbine wheels with bright trim rings, a chrome seatback fuel tank, a single drum brake, a black vinyl bucket seat, and a three-spoke steering wheel. This Rupp Grand Prix is now offered by the seller on behalf of the current owner at no reserve in Gilbert, Arizona, on a bill of sale.

The frame is said to have been stripped and refinished in a metallic red under current ownership along with the matching Nassau panel that features a #1 race number and a manufacturer’s plate labeled “Grand Prix”. Additional features include rubber seat and engine bushings, a polished aluminum floor pan, and a chrome five-quart seat-back fuel tank.

The 5″ turbine-style wheels feature chrome rims and center caps and are fitted with Vintage Speed slick tires. A drum brake with chrome hardware is mounted on the rear axle. The tie rod ends and brake rods have been re-chromed.

The driver is provided with a single seat reupholstered in black vinyl with white piping and a Dart Kart logo, while a three-spoke Rupp steering wheel is mounted aft of chromed foot pedals with black rubber covers.

The twin McCulloch MC-91 singles are equipped with velocity stacks, Tillotson carburetors, and Azusa pea-shooter-style exhausts. Power is sent to the rear axle via rebuilt Hortsman Rev-Grip centrifugal clutches, drive chains, and replacement sprockets.
