1973 Suzuki year code: K

TM125K (1973)

The TM125K production racer made its appearance in 1973 and was called the ”Challenger”. The engine for this lightweight and schoolboy scrambler’s favourite was based on the Suzuki TS125 trail bike, with many modifications. It produced 20 bhp at 10.000 rpm on open pipes or 18 bhp if the silencer was fitted. The colour is quoted in the parts book as Aspen Yellow (Suzuki colour code 163). The fuel tank had Suzuki stickers and a blue/white stripe went round the back of the tank where the letters TM appeared.

TM75L (1974) The TM75 was very much based on the Suzuki TS50, infact they both use the same frame. Mainly a schoolboy scrambler starter bike the TM75 is probably more famous as a pit bike for the road racing stars like Barry Sheene. It had a rotary disc induction with the carburettor on the right hand side of the engine. It had the Suzuki posi-force two stroke lubrication system with oil tank under the right hand number plate. The clutch was operated by a worm mechanism on the left side engine cover and unlike the other TM’s it had point’s ignition. The engine hung off the frame and the front frame down tubes were just there for show. Footrests were rubber covered folding type off the TS100 and as a safety measure a chain guard was fitted above the swinging arm. It had a rod operated rear brake and its own ally forks. The fuel tank had dark green/white stipes that did a U round the rear of the tank.

Front forks had been changed and the exhaust had a rear silencer on it to keep the noise down, as well as having a black coloured exhaust cover instead of the earlier chrome type.
