At some point it becomes a numbers game... I have more than you have kinda thing... It's all about what feel comfortable to YOU... I rode a Raider the other day... to me, it feels heavy and sluggish to respond to manuever... has a nice feel when you roll on the throttle though... I had my wife on the back of my STRYKER and was neck and neck with the raider at 95mph... We both had plenty of gas left... for real though... max speed limit is 70mph on most hwy's... 85mph would most likely get me a huge ticket and my bike impounded....
