Would this be legal? twin cylinder 250

Would a TZ250 engine be legal in a YZ250 frame? Would you ride it?
It would be cool if someone stuffed one in a YZ250 though.

I think it would be officially kick-ass!  I've always liked the idea of making two-strokes go multicylinder.  My dream is to one-day see a high performance car being powered by a 2T V8.  Preferably with a Dodge logo on the hood.

Here ya go, a 2 stroke V8 in a sand car.
2 Stroke V8 in a Sand Car   hope link works.

It's a Evinrude 3.6L V8.

Or click the link for pics of the Yamaha RD05 road racer. It's a V4 250cc engine with rotary induction.

I've seen that Sand-car many a time.  I'm still looking forward to a major auto manufacturer putting forward a serious car with a 2T under the hood.

Maybe an AMERICAN car company will get it's head out of it's arse and build a two-stroke car. But first they have to get through emissions testing.

Well, the snowmobile and outboard people are showing that it can indeed be done.  I'm just waiting for someone to apply that technology to the car world, just as that sand-car was using an Evinrude motor.

Yes and if I had the money I would start building cars, trucks, motorcycles,and powersports. Then my final goal would be to just beat Honda at there own game using two strokes. But only if I had money.

I remember seeing European 2 cylinder 250cc 2 stroke works bikes at the Unadilla USGP in the early '80's, but I don't remember what brand they were, maybe Aprilia or Puch.  They were in-line 2 cylinders, not v-twins, obviously hand-built, and sounded unbelievable on the track!  I would have loved to have ridden one....

I would say someone should bring the multi cylinders back!! Maybe a 125 twin from an old Yamaha in a dirt bike frame. Hell they had a TZ750 stuffed in a dirt tracker frame and raced by Kenny Roberts, so anything is possible.
But can anyone be able to ride one, most likely not. These engines produce a lot of power at the top and little at the bottom.

Somebody in Germany is racing this 250 twin ADLER with very good results,but he admits that it took him a long time to get used to the uprupt powerband.

Here's one Honda raced in the early '80s, O'mara I beleive.
Work of art that front end.

I think it was Roger de Coster.It was a interesting project by Honda just like the OVAL piston.But it never came trough.

My feeling is that the direct-injected 2 stroke would show up on a super-car before a mass produced economy car, for several reasons. First I can't imagine the general public ever buying into adding oil every month or so, but a quirky super-car has all kinds of inconveniences that its owner must deal with. The expansion chambers present a challenge that would probably best be solved with a rear engine design. And lastly, the high performance and light weight that a multi cylinder big-bore 2 stroke could offer is perfect to compete with Ferrari's, Porsches and Lambo's
