The J&J Amusements Sidekick has it all — including one of the largest cockpits in the industry! The Sidekick is J&J Amusements’ original two-seater go kart that had revitalized the go kart industry back in 1993. To reduce risk and exposure, all moving parts are covered and guarded. The stylish Sidekick go kart two-seat body has the most exterior room for customization and advertising space.
