Donb't go puting my opinion between yours and jeffs. I sure don't want anything to do with that. Your Ninja makes pretty much the same HP that my 1100 Guzzi made. I rode that Guzzi 60,000 miles and it worked fine for me. Not sure whats meant by 'bigger' but if its 'more power' then all I can add is that I never felt under-powered at 65 rear wheel HP.
