All you need to know about the 125...

Yamaha TZR 125

My first 125cc motorbike. After a poor start with my TZR125, like it being slower than my previous Derbi Senda - a 50cc, 55mph rocket ;) once I got the TZRs powervalve spot welded open, all was good.

It was really revvy, and had an extremely narrow powerband, but it handled pretty good, and I learnt a fair bit on it.

The newer, RR models of the Yamaha TZR 125 are pretty good to look at, and a bit quicker I'm led to believe.
