Suzuki TM75, TM100, TM125
1973-1976
I have tried to tell the model history of the Suzuki TM 75, TM100 and 125 models on this page as the know it.
I would be grateful of any contributions sales brochures, magazine ads,
magazine articles, pictures, specs, facts, corrections etc. Please scan the material
in JPEG format (large enough that all the details are visible) and send
them to me. Please tell me the source and the publication date if possible.
If you send me pictures of your own bike, please follow these
instructions. |



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 scramblers 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 TMs it had points 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.

Virtually the same as the '74/'75 models the TM75A model was the

and the side panels were yellow with black number plates stuck
on. 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.
