No a 125 frame is too small to fit a 250 motor but with a cutting torch and a welder anything is possible.
The TS125 engine will fit straight into the TS100 frame. My TS100 has a 125 in it and it rides very well.
They are 8 years apart they changed the frame in that amount of time I would mesure the size and locations of the holes on both the engine and the frame but my bet is that it won't work, there is a big difference between the styling on a 1992 to 2000.
if you modify the frame it will
1999 2000 and 2001 engines all fit on each other
nope. You problably could by doing some frame cutting .
yes its is the same engine
yes
Sure will iv done 2 now
yeah
Yes it can! How much work I do not know. I saw an 80 a few years back with a 125 engine in it. I just got cr80 and I'm going to put a 125 engine in it, just to play with people at the track. I'll let you know how hard it is.
yes it can i have done it
