this is hard to define and put into words.
my 9 is the first bike i consider to myself to have really ridden. not just owned, and took out on the weekends if it was nice.
10k mi. a few tires, wrecked it alot and then fixed it. as many smiles as miles. it is like an old friend. i truly feel i know it. i have ridden it to it's limits and pushed past them. i am very comfortable, knowing it's and my capabilities.
even at 2K mi on the 1125, i still am feeling it out. basically i take it easier on the more capable bike cuz i'm scared of it. it has a different riding stance and powerband. it has more power than i really need, and don't hit WOT nearly as often as on the 9. still the acceleration makes me grin EVERY TIME. it is like my mistress bike. tons of fun, but i better check my mirrors and hang on tight or im gonna get burned.
i knew i wanted an 1125 since the first of several test-rides, and had it in my sights. but the fire-sale made me pull the trigger.
i put heated grips on the 1125R, and it has a full windscreen as opposed to a bikini fairing. other than that, i have no preference day to day.
