[2] The engine was lubricated by the proven Suzuki Posi Force system,[2] which injected oil onto the conrods, big ends and cylinder walls.

The model used the front forks, 24 mm carb engine, tail lamp bracket, seat and clocks of the T21.

[5] The T250-II (Mk 3 in Japan) had a new teardrop tank, seat, front forks and individual instruments.

[8][9] Larger 26 mm carbs were fitted to the '71 model along with wider tyres and there were cosmetic changes to the paintwork[2][5] along with new switchgear.

[5] Only available in the UK, the TT250 shared the same tank and side panels plus cylinder heads as the T350 Rebel.
