Can't tell if someone has posted this.  This makes me hawt!

Road legal version has 53 hp, 308lbs wet, 650cc Rotax single (same as BMW model) and Italian designed.

Track version has 68hp, weight is 128 kg dry.. WOW..  Has Marvic Piuma magnesium wheels.. sweet.

I want one.  I think we are going to Milano now.

[pointy knees] I don't know about that headlight/beak assembly [/pointy knees].  Otherwise, sexy as hell.  Wire spoke wheels give me a chubby.

Don't like the vents for the radiators.  Other than, I think it looks very nice.

A Husky 450 will put out the same power, is 50 lbs. lighter, has spoked wheels, 50mm inverted forks, and radial Brembos.

You could start with one of those, lower the suspension, ditch the MC style bodywork, add a real seat, and have a better bike.

And a Japanese 1000 will smoke a 1098... What's your point?

The weight alone makes it interesting to me.

We're talking single cylinder motorcycles here.  I don't know of any Japanese twin that will smoke a 1098.

Rotax makes great powerplants but the 650 mill that BMW has been using is heavy and underpowered.  If you are looking to make a nice sporty single cylinder bike, there are much better starting points.

All the numbers I've seen on the SM450 show 45hp, not 68.

Where did you see that the SM450 put out more than 45-50 hp?

You'd be doing a lot of work rather than buying something "pret a porter"..   Sure, if you have a workshop and a personal metal or plastic fabricator handy, you could make just about anything.

The Vun bike actually exists -- the bike you describe doesn't.

The SMR 450's I've seen on the dyno put out 53 at the wheel.  The 650 Rotax would be lucky to get that at the crank.

True.

also to mention that 50lbs less weight would feel a lot more like the extra hp in the track bike. That bike looks sweet the way it is but there's some obvious weight saving opportunities on it as well.

I think it'd take some framework to make the husky really doable though more so than just lowering the suspension.  almost looks like the rake is a little longer on the VUN.  i'm only debating this because I'm trying to picture what I'd have to do to my husky to make it function like a MITO or VUN....

You'd have to really mess around with the suspension and geometry to get it into road race mode. I think the swingarm and shock would be the difficult part. I can be done, there are some new supersingles based on motocross frames, engines and swingarms with sportbike front ends and road wheels.

Roland Sands converts 450 mx bikes into track bikes, that seem to be better than this VUN, But me likey the Vun styling

I've been following this genre(?) of bikes for a while and the most promising is a rumored KTM sport single, hopefully coming out in the summer.

Regardless, what I want is:

Road Legal
Under 300 lbs
Sportbike (i.e. decent suspension)
At least 50 hp.
And doesn't require a complete rebuild every 2000 miles

Basically, everything my built-out RZ-350 had back in 1989.

Seriously, is 20 years long enough to wait to get four strokes back to what 2 strokes used to give us?

Those singles require so much maintnance its retarded. ... measured in hours not miles.  they are all designed as race bikes.  With an external oil cooler and larger capacity, swapping out the titanium valve pieces for stainless you probably still are looking at a top end every couple thousand miles that if you kept it off the rev limeter you could extend to 5-7k.
