All I can say is it's just like a CR 500 power band. Unreal fast, power comes on and the front end pops up instantly. Quality of the parts not to great, everything is cast and looks rough wasn't impressed by that at all. Most the panels are nut and bolt. Which is shitty to work on.
The power is way to much if your ever thinking of getting the dualsport version. I couldn't imagine riding it on tight nasty trails you would be fiighting the bike all day.
As a motard this think is going to rip hard on the track. In the right hands this bike will fly. I doubt a beginner would be able to ride it too it's potential. It does look really cool and will be turning heads all day. It sounds really good like a hyper V twin. You'll know it's an Aprillia coming before you even see it.
Overall I like it.
