Ok, while the Harley Revo motor is a nice motor. It still took wayyy too long for that to get here and it's still not the greatest. I was surprised that it actually was a 60* V like the Aprilia. The motors seem very close in design, except the Aprilia's Rotax motor can rev 2,000 rpm higher and makes 15 more HP at the crank. Now, sadly, that's outdated as my motor is 5 years old. The new Ducati 1198 (close to said revo motor in size and design, aside from the 90* configuration) is making 180 HP and 93 lb-ft of torque! Aprilia's last 60* V-twin in the RSVR is making roughly 150 at the crank. The revo motor is definitely not an end all motor and it surely is not up there with the likes of the other V-twin superbike motors. I'll give it to Roehr for making an original design (even if I feel they ripped the nose straight off an MV Augusta) but it's still underwhelming, overweight, and waaaaaayyyyy overpriced for what you're getting. Congrats, they stuck a supercharger on a V-rod motor. I'm a little upset that they had to S/C the motor to get the power needed. Ducati still walks over it every day in every category. Sorry.
