Aprilia RS660: Probably the world's most powerful parallel twin.?
Aprilia claims 100HP and a dry weight of 375lbs. Probably around 400lbs wet.
To put things into perspective, the legendary Kawasaki H1 Mach III had a wet weight of 405 pounds and made 50ish horsepower.
Not too shabby for a 4-stroke 270 degree parallel twin, eh?!
I'm impressed. This bike isn't for me but I'm definitely impressed.
