The Suzuki TM125 Challenger, produced from 1973 to 1975, was a motocross motorcycle renowned for its racing-oriented design, directly inspired by Suzuki's factory machines.

The 1973 model (TM125K) featured a black-painted engine, an aluminum cylinder, and a Pointless Electronic Ignition (PEI) system, with a 5-speed manual transmission. The fuel tank was Aspen Yellow with Suzuki stickers. In 1974 (TM125L), a new fuel tank design emerged, featuring dark green and white stripes. The 1975 model (TM125M) introduced a new swinging arm and suspension units, along with an entirely yellow tank featuring a "rising sun" type Suzuki logo.
