What a wonderful little bike.

We did not get the GT80 in the UK, or if we did, I never encountered one or even heard of one.
We get imported ones appearing now and again and when the DT is sorted, the GT may be my next project.

What we had in the UK was the Trial 80, which was a juniors trials bike. They look like very close cousins.
Back in the mists of time we had six TY80s on fleet, so no stranger to rebuilding those.
Not that I remember much about them.

TY80. I would guess the engine and frame is the same. They went like stink for what they were. Very perky motor.
