New 500cc 2-stroke motor revealed

Interesting stone scoop

3 cylinders and a smell to die for Emissions?

Tempting

The engine sounds interesting but that sure is an ugly concept bike...

Shame its ugly as hell, won't do the two stroke image any good

+1 to both of you. That is one ugly bike and i dont really know if it being the only 500cc 2 stroke will be its saviour.

I think i would still prefer a classic RG500

Hell yes or a rd500. but thats me, I'm a yam kinda girl.

Posted: 21/03/2008 at 21:27

Yup RG or RD for me as well but a bit of progress is not a bad thing.

Get a polish 500 smoker and swap the lump into something that looks pos handles better and there you go

Padgetts had and RD500 for sale the other week, I couldnt see any RG500s there tho

RG500 is one of my must own bikes alsong side a 70's Z and a cafe racer

Those exhausts will have to change - no expansion chambers in the pretty ones they've drawn.

S'just what I was thinking. Interesting looking bike, mind. Wonder where the carbs sit and what shape the airbox takes - or if it's as well designed / thought out as the exhausts.

I get a feeling the bike might be some MA student's final project / not really feasible, but likely to score a first.

Let's see and hear it running before believing all the marketing hype.

I thought Ford had a 2 stroke car of 2 litres in development, don't know if its a radial or what but apparently with direct injection to the crankcases plus full exhaust catalysers/spark arrestors etc they can apparently be made to run very cleanly.

Whether this cures the perennial problem of 2 stroke cooling and lubrication deficit I don't know but obviously if this is a radial motor the problem is rather sidelined as you simply don't have the bore issues.

I would have thought it's a 4 Cylinder since it's an X4 radial motor.

looks like a four stroke to me.

Posted: 24/03/2008 at 21:44

You can see in this picture it is indeed a radial 4 cylinder motorcycle and the carbs are on the side of the cylinders.

I quite like it, but I've always had a thing for radial engines. I saw a 1930s motorcycle with a radial engine mounted in the front wheel at an exhibition a few years back and looked amazing - probably handled shite.

It looks horible and as for being a two stroke it should be consigned ton the graveyard
