I don't really care for it at all, and I'm a track racer, I like speed, But I also like functionality, It's supercharged which the only benefit I see there is in the straights but it will probably eat tires, It's Nearly 80lbs heavier than the zx10r at 524.8lbs, The wheelbase is about an inch longer, Lower compression so I would assume engine braking is not as good which could hurt times and will cost you more in brake pads.
Let's not forget the base model looks cheap, Definitely not 25k worthy, Taking a zx10r or a new R1/R1M and putting what you have left over would definitely be the better way to spend 25 grand.
It's also overhyped, Everyone just heard 300hp and suddenly it's the greatest bike ever built, I promise, Though a much more expensive and not available to the public bike the RC213V exceeds probably even the H2R's abilities.
