I can supply standard Yamaha OE JT in black or gold for £127,
Or
RK 530 GXW Race spec kit for £139
Or
DID 530 XVM-X Top spec kit for £154
I personally do not like DID kit, I know a lot of people swear by them, I have fitted and sold quite a lot of the standard fitment ones now and although a little dubious at first I have had good feedback from them.
