Does not cover all models of DT50. For example, manual gives no information on liquid cooled engines. I own a 1989 DT50, liquid cooled - manual does not cover this. Manual supposedly covers models up until 1995 - not true. Furthermore, manual does not contain accurate wiring schematics for my 1989 model year either.
Binding is less than adequate also, as my manual is already having pages fall out of the seam after minimal use. Manual was written in England, in traditional British language, strange spelling, at times.
Overall, the "Yamaha DT50 and 80 Trail Bikes Owner's Manual" is just "OK" - better than nothing? It really is not all that all bad, however, could be much better.
Not worth more than $15.
