If what you are most interested in is better acceleration, weight loss is an extremely expensive way to achieve very little improvement. If you're into cornering, weight loss will help but it won't help much unless you also practice. I believe your cornering will improve way more through practice than it will through weight loss. I got Carrozzeria rims for my 14 and have removed over 75 lbs from that bike and I don't corner any faster on it than I did with stock wheels. I corner just as fast on my busa which has very little weight removed except for switching to a full system.
It seemed like I did notice a small improvement in acceleration with the Carrozzerias but I never did any timed runs. Any improvement would have been a fraction of a second, could I really feel that? IDK. Maybe it was just the sensation of less rotational mass in the wheels that I was feeling through the bike. One thing I can say is that I was afraid to lean the bike as hard for about two years. I could also feel the effect of reduced gyroscopic force in cornering and it feels less stable, less planted on the ground.
If you buy some CF wheels, I think you will like them. I like my Carros but the stockers were not that much different to me even though they are much heavier. I'm hoping to buy some CF wheels for my busa soon but I already know they will be better than I am.
