Price on application! Due to the various permutations of wheel spindle size, caliper colour and other details, price is very variable, and stocks are low on some rarer combinations. Some 2 valve twins built between 1974 and 1980 had only one front brake disc. This conversion includes fork slider with caliper mount, reconditioned brake caliper, twin feed master cylinder, disc and all mounting parts, and a new set of pads. Dramatic improvement in stopping power! Price reflects a kit made entirely with used and reconditioned parts (except pads!); if some parts have to be sourced from new stock, price will be more. Brake hoses are not included and there a several options to choose from. Please phone to check availability and discuss options. Please note; this kit DOES NOT APPLY to models built from 09/1973 to 09/1974, due to the extreme rarity of the right hand fork slider! Also, /6 models will be supplied with the later 17mm diameter master cylinder, not the original 16mm item.
