Not from my experience. Ive raced a few T5 bikes and beat them all. It always seemed to be top end power that got me the win. Of course porting differences play a huge roll though.
My advise is for anybody that thinks they want to try DMC 916's... Get them. I almost guarentee youll love them. The sound, power delivery, and look are top notch. If you want everybody else has got get the T5's or some FMF's.
