RM, I believe the Vulcan 900 is rated at 53HP. Not much HP but pretty good torque. I boosted the HP by installing Cobra 2 into 1 Pro pipe HP. Haven´t dynoed it but believe that it should be about 58 by now. Also needed to install the Cobra FI2000R fuel management system. I am waiting to see aftermarket air cleaners for my bike as well. That should help tremendously. I´ve had my 900 for 6 months now and have about 5,000 miles on it. Good luck
