200litres
There is no TZR 125 being in production now, but if it was a 2 stroke I calculated it would go an easy 145-50Km/h. If it was a 4 stroke it would get up to about 130 and 110 cruising speed. If you mean the old TZR 125 then that bike got 110 4 strokes and 140 2 strokes top end.
the 4dl belgarda tzr 125 shares the same deltabox frame as some of the 250 tzrs and the szr660 so yess i believe you can fit a 250tzr engine fairly easy into one. however finding a tzr 250cc engine would be hard to as they are getting more rare by the day . and the 250 fetches more money than the 125 .

TZR's are available for purchase from motorcycle retail stores. It is important that the store includes Yamaha motorized vehicles, otherwise one cannot find a TZR at that establishment.
You can usually contact the manufacturer and receive a diagram. You can also call auto places in your town like Advanced or NAPA.
