This 1969 Rupp Chevy Junior go-kart was manufactured by Rupp Industries of Mansfield, Ohio, and is based on the design of the 1965 Chevrolet Monza SS show car. The fiberglass bodywork is finished in red with white Chevrolet-branded stripes and is mounted over a tubular steel frame. The single seat is trimmed in black leather, and a 5-horsepower Briggs & Stratton single-cylinder engine is fitted out back. Acquired by the seller in 2026, this Rupp Chevy Junior is now offered at no reserve in Saint Petersburg, Florida, on a bill of sale.

The original Monza kart design was custom-built at the GM Tech Center for Bill Mitchell’s stepson and Chuck Jordan’s son. The karts’ popularity inspired General Motors to contract with Rupp to produce a run of karts for commercial sale based on an existing Rupp chassis. Rupp later marketed the kart as both the Monza Junior and Chevy Junior. This example is finished in red with white stripes, Chevrolet lettering, fender liners, and a silver taillight filler panel with quad reflectors and a “Chevy Jr.” plate. Imperfections can be seen in the gallery below.

The 5″ wheels are mounted with 4.10/3.50–5 Cheng Shin tires. The tubular steel chassis is derived from the Rupp Dart Kart and shares that model’s mechanical layout. Braking is handled by a single mechanically operated rear drum.

The cockpit features a single seat and side bolsters trimmed in black leather. The three-spoke steering wheel is mounted ahead of a semi-reflective Chevy Jr. decal.

A Briggs & Stratton 130202 5HP engine was installed under prior ownership. Power is routed to the rear wheels through a centrifugal clutch and a drive chain. The oil was changed in preparation for the sale. The manufacturer’s plaque is missing.
