Not for me...I hardly ever use the back brake, except to hold the bike on a hill start so on my 888 it would just be a cosmetic exercise to look a bit tricker than standard.
Rather spend my dosh on summat functional rather than just cosmetic
: "Says the bloke who's just bought a carbon fibre mudguard for it, how's that more functional than a plastic one?"
Jools: "It saves weight and it looks nice"
: "So just cosmetic then ya dozy bastid"
Jools: "Feck off rodent"
