Roadworthy, how would you do that (bump HP)? I would be interested in more ponies, but never at the expense of reliability or longevity. In all honesty, I'd probably be just fine with the stock version. But I'm surprised that my VStrom actually generates more HP (I didn't look, but I believe it's rated at 65hp). I admit my ignorance on this subject, but I'm going to assume the higher HP out of the VStrom's smaller engine is due to the Vstrom being water-cooled?
