Length is the same as the stock forks, 760 mm if I'm not mistaken. A GSXR 400 SP has exactly the same forks by the way. 6 pot calipers is just masturbation
It brakes very good though but 4 pot calipers will brake just as good, and a 4 pot caliper stays cooler under extreme conditions. The rear shock I use is also from a GSXR 750 W, I had a 750 K2 shock before but the 750W one is much better.
My first priority is to get some other mirrors, these are crap
