the 26" mud lite has a deeper tread then the 26"bear claws but if you go with the 27" bear claw you get the same size tread as the 26" lites.
my friend had the 27" bear claws on his 03 660 griz and they were impressive.
your 750 kawi can handle them with ease.
i got 28" mud zillas on my 700 and it still spins like nothing.
my buddy has 26" claws on his 450 yammy and it has over 1500 miles on it and they are about half worn down.
your 750 will kill the rear 26" claws in no time.
i have 2500 miles on my zillas and the fronts are still like new and the rears have no grove left so there almost half.
but they still work great in the mud and in the snow also.
if you going with the claws get the 27s there better then the 26s.

 

Well after all of this talk about the claws, I think I will have to try a set of 27". I am a die hard fan of ITP, hence my good luck with them. (My 94 fourtrax has 1000 miles of tar with mudlights and they are not that bad!) But I'm always open to try a new set of tires, and I do primarily mud riding, so I hope they work as good as the lites. Thank for all the imput guys, evan though this isnt my thread haha.
