Would it be possible or worth while to make a trx 250R/Raptor 660R hybrid? The frame of a 250R with the big ass 660 motor. Has anyone done anything like this?

Anything's possible with the necessary tools and a lot of time. Although I've never heard of such a hybrid.

250r is a good machine, but I think it would take a bunch of welding and relocating the gas tank. Four stoke engines sit taller than the 250 2 stroke. Id see a 250 two stroke in a yfz frame to be a good one. I also like the yz80 motors in blaster frames.

i bet it lowered the c.o.g. too. :grin_nod:

The 660 is a tall engine, you'd be better off using an xr650.

cr500 if it wouldnt kill the welds on the frame

I have seen (on the net, not in person) KTM 525 2-stroke motors in customized 250R frames. Now there is a quad I would like to try out.

Pretty sure the biggest ktm 2 stroke is a 380 and it was just discontinued not long ago. 520 and 525 are thumpers.

There is always the ATK 700 2 stroke. That there is just crazy.
