When I was having my 2014 Rocket roadster dynode the dyno guy said he had recently tuned a Harley with that motor in it plus the owner had spent a lot of coin on extra **** for the motor and the best he could get it to was 125hp at the rear wheel. He overlaid my tune over the Harley tune and mine was around a half inch higher on the graph than the Harley. My bike was a stock standard motor but I had added ramair induction, the bigger throat mufflers and a decat pipe system for a nice airflow. The R3 ended up 134hp at the rear wheel. BUT.....you cant put a guy down cos he likes Harleys...I have some good friends who just love their Harleys like I love my Rocket....alls good as long as you ride right?
