1973-81, 123cc t/s twin, 16hp 80mph 70mpg 260lb

What to Expect

Hotshot stroker twin that eats plugs, seals, but can be reliable and fun device. Reed valve made it more useful in town than older twins. Often needs a rebore and new crank bearings at 20k. 1976 model onwards has a square look and front disc brake in favour of the classical shape and exellent TLS drum of earlier bikes. These later models lasted for 30k, less susceptible to the ign timing and had more low end torque Also some detuned post ’81 bikes.
