TM250J (1972)

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). Suzuki’s 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.

TM250K (1973)

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.

TM250L (1974)

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.
