I recently bought a Yamaha TDR 125. I just done my CBT again as it was 5 years ago that i last did it! It is a nice bike all round, good quality, nice riding position, good suspension and very good brakes. But I wonder if it still restricted, I didnĀ“t think it was cause the lad who owned it b4 had put a new exhaust and had the PowerValve connected. Even so there is a way of getting 18 bhp out of the PV that I heard mention about.
