Here is the FP Racing brake relocator bracket. It is lighter than the stock bracket but has the advantage of slipping the caliper under the swing arm like MotoGP bikes. As always, if it's good enough for the Race teams then it's good enough for me! It's worth pointing out that I was going for the Brembo underslung kit but this was a fraction of the cost and fits standard wheels (the Brembo kit does not). The bracket weighs just 319 grams and made from billet and allows the standard rear caliper to be used.
Well I doubt I will ever be brave enough to buy a conversion like this but saw these and the think they look amazing. I find that a great deal of headlight conversion often look tacky and dread it when I hear of angel or demon eyes. These however seem tasteful and do seem to suit the lines of the bike.
