Old thread, but the above is BS about the octane power output. My friend just picked a brand new one two weeks ago. I rode it about 40 miles and it absolutely moves at ALL rpms. Throttle response is better and pulls hard the moment you whack the throttle. I am sure gearing plays a big roll here since he has a 6 speed to our 5 speed. I just picked up a roadster 3 days ago, and no where power wise does it come close to matching an octane. His bike handles nice but i really dont enjoy forward controls pushing a bike through some twisties, though its good for my knees.

I just hope when my 2 into 1 exhuast and tuner shows up i can keep up. Right now looking at a dyno chart from a stock octane vs a stock roadster based on 3500 rpm.

Roadster: 45hp / 68ft-tq
Octane: 46hp / 69ft-tq

Looks pretty close until you factor in the gearing, which gets him up to his peak power quicker and it might even be a few lbs lighter.
