newbie question but what would be the advantage of this? bigger breaks or better handling?

 

Mainly for stunting it wheelies and stoppies are much better

 

so what do you need to switch over to 954?

 

900rr 929rr or 954rr or 1000rr front wheel f4i brake calipers work but you need to trim one of the stops that keep your brake line from rotating where it bolts to the caliper. I only had to do it on one side. Handlebars are kinda challenging. I went through a few different set ups to find one that works pretty well but you lose some mobility. You wont have full lock. Meaning you cant turn the bars all the way without hitting the fairing stay or the ram air covers. Your ram air tubes are useless too. The 954 forks wider, so the tubes dont fit, you dont need them, the bike breaths fine, I cant tell a difference.. Im currently running woodcraft 3 inch riser clipons to clear the ram air covers, but like i said im still hitting the fairing stay on both sides. You dont really turn your handle bars at speed anyway so its not that bad, low speed turns can be tricky but not impossible, just takes some getting used too. If you're doing the 600rr swingarm swap you need the rr bracket for the rear caliper, the brake line and the back wheel, but you can use the f4i back wheel with custom spacers.
