Google says the R1 is 382 dry, 426 wet, and the Warrior is 606 dry, 658 wet. But I've got 100 ft/lbs vs: the R1's 75, so if I lost 100 lbs (aluminum or composite tank, fender, R1 wheels, swingarm, mated to Warrior drive pulley, though, perhaps, a couple teeth smaller, and a smaller, better designed frame) I might be able to keep up in spite of the severe rev handicap and the the lack of a 6th gear. Pretty sad for 700 cc's more displacement, but, hey, pushrods and air cooled. It would be unique, though, and that's a good thing. If I lost 150 lbs... I could *really* make it go. And then if I did some work to the internals, programming, and induction system on the engine, it could also make more power. (And get even worse gas mileage...
In fact, that would be one major advantage of raising the gas tank and leaving the motor where it was, the airbox would eat less of the tank's volume, and it might actually develop a decent range. Plus, while I was at it, I could make the sportbike of my dreams, namely, one that fits.
Yes, I realize it's somewhat hubristic for someone without a full engineering team to talk about improving the frame design, but they were also handicapped by a certain set of aesthetic limitations (they intentionally made the frame look like a welded tube style 'old-school' bike frame) even though it's aluminum. So there is probably room for improvement. And, I'm a welder, a machinist, a computer programmer, and I have an engineering degree, so it's not impossible.
Ah well, I have to finish building my car first. (Not to mention pay off the bike, before I start taking it apart...
