I'd like to see what the actual bike would weigh in at. Not to mention that they'd have to do some serious modding to the engine because that Revolution engine is a very slow revver. Powerful, yes, but revs slow as hell. When we do roll-ons on the freeway, my KTM is up and gone and my homey's Street Rod could never catch up even though it puts out 20 more horses. You rev the throttle on that Revolution engine and you'll wait for a couple of seconds before anything kicks in. So, I'd like to see what Roeher did to solve that problem.

Well the obvious solution would be to lighten the crank/pistons. Not to mention the super charger which should get things spinning alot faster. They claim a 425 dry weight and they say "modeled" after the hd lump so they might have a cnc/lightened version of the engine. They had to save weight somewhere considering my bike weighs about that.

As far as the price goes,it's not THAT much more than the MV,Bimota or Ducati specials we've all seen and it's still cheaper than most of the choppers riding around. I read an article about this guy almost 2 years ago,he just about hand made everything on the prototype himself.

Why Polaris won't make a sportbike has always been beyond me. Harley tried it and failed. We probably wouldn't buy it even if one of the American Companies did produce a sportbike.... I'm still hoping Buell will do something now that they've broken with HD engines! They're definitely heading in the right direction.

The price doesn't bother me if the quality and the performance are there. It's not any more expensive than a special edition Duck or MV. BUT I really like to see how he overcame the weight issue. Unless that V-Rod engine is totally remade with aluminum, magnesium, and titanium, he's not gonna be able to shed that much weight. The BMW HP2 Sport has a 1200-cc aircooled boxer twin engine (no water pump, no radiator, no water jacket) with the most exotic parts BMW ever made for that engine, coupled with a lightweight trellis frame and a carbon fiber subframe, lightweight PVM wheels, etc., yet it still cracks in at low 400-lbs. Or the KTM RC8 with the 1200-cc (okay, 1150) watercooled V-twin weighing in at around low 400-lbs too.

So, in order to overcome that heavy ass Revolution engine's weight, Roeher must have done some wicked shits. I'm sorry but I'm skeptical until I see some real data and engine/frame designs.

maybe Ford or GM will decide to try to "Revive" their companiers by going the sportbike way..........

Bottom line is I would buy an MV, Ducati 1098R long before i would buy a H-D powered anchor!

They did a nice job of copying the MV Augusta's looks.
