I just picked up my new HP 4. All I can say is WOW....
My current bike a 2010 S1000RR with 42,000 miles & a ton of good stuff.
BST carbon wheels, Ohlins forks & rear shock, Akrapovic titanium exhaust, PC-V w/Dan Kyle's map, Hid lights, heli bars, etc.
The suspension is unlike anything I have ever experienced. This suspension is right on on every type of road.
The HP 4 is smoother, has more mid-range & is overall a much more refined machine.
If you ride one, you will want to buy one.
