will a90-93 cr125 fit a 84 200x?

[bigred1]

just curious if anyone knows if it will fit..... also is there realy much diff between a 125 two stroke and a 200 four stroke

Are you talking about engine? Im pretty sure it would fit no problem. Me and my friend were talking about this earlier, and how small the 125 engines are. Top speed there not real fast, but accelleration is great on them. But then again thats in a dirtbike frame, not a trike that weights 280lbs.

It will fit, but finding a place to mount the rads might be tricky. That, and routing an expansion chamber in a 200X frame isn't fun...beleive me.
Although, since the 125 is smaller than mine, it probably wouldn't be as difficult, but still takes some creativity and patience.
With the right gearing, and a good pipe, the 125 2 stroke would probably take a stock 200X. Maybe not off the line, but as long as you kept it in the powerband, I think it'd be fine.
That engine would probably shave a good 20lbs off the X alone. Stock motor weighs 60lbs if I remember correctly, my 175 weigh 45lbs, so a 125 would be less than that.
