TM250 1972-1975 I
have put some Suzuki TM-250 brochures and facts on this page.
Please send me more stuff to put here. I want brochures from all over
There's also a separate page with a Cycle World road test of a 1967
The new TM250J and was knicknamed the CHAMPION, After
the RH71 works 250 ridden by World Champion, Joel
Robert. It was based very much on the TS250 trail bike and shared
many engine parts including the figure of eight type Magneto cover
and clutch operated through a worm and push rod arrangement. The
sprocket cover was fitted with three diagonal slits and all the
cases were finished in a satin matt black colour. The compression
ratio was 7.5:1 and had a fan type cylinder head; the piston bore
size was 70mm.
An exhaust system with no rear silencer certainly made the machine
sound good and courtesy of a five-speed constant mesh gearbox
it produced 30 bhp at 7,500 rpm. A 34mm Mikuni carburettor was
fitted and foam air filter was boxed under the seat.
Ignition was by PEI (pointless electronic ignition). Suzukis
own Posi-Force lubrication system was used with the two-stroke
oil tank being fitted under the right hand side number plate.
Footrests were folding fabricated sheet steel type. The fuel tank
was in yellow (Suzuki colour code 163, Aspen Yellow ! ), it had
a black stripe following the outer shape of the tank and had Suzuki
badges screwed on top of the stripe. The tank cap was a steel
twist type with a breather pipe. The wheels had aluminium alloy
rims with a 300x21 knobbly tyre on the front and a 400x18 fitted
to the rear. The total weight of the bike was a very competitive
220 lbs dry.

Very similar to the 72 model the K had the following changes.
New type clutch cover with a rack and pinion type clutch operation,
although the magneto and sprocket covers were still the same.
The folding footrests were now the later type cast steel. Rear
suspension units and swinging arm were the same as the predecessor.
The fuel tank had Suzuki stickers instead of badges and a blue/white
stripe went round the back of the tank where the letters TM appeared.

Much the same as the 72/73 models the L had these
few differences. Straight type finning in the cylinder head. Smaller
type magneto cover and a sprocket cover peppered with seven holes
to clear mud easier.
A rear silencer was now fitted to the exhaust to lower the decibels.
Front forks, suspension units and swinging arm were all uprated.
The rear mudguard now bolted on to the rear frame loop. The fuel
tank now had dark green/white stipes that did a U round the rear
of the tank.

Just a few changes over the previous models for the M model. The
gearbox had some gears with different ratios. Suspension units
were again different. The fuel tank was all yellow with the Suzuki
logo written over a rising sun type design.
