These were used two weekends by the guy I bought them from. I was going to use them on my 2012 Gsxr 1000. I just got a new bike that is eligible for contingency in supersport so I won’t be able to use them. They come with spacers to enable use on the 09-16 Gsxr 1000 but spacers can be bought to use on any 108mm caliper. Also included is two sets of race pads. Retail on these calipers is $2205 not including pads, spacers or shipping. The brake pads retail are $343.96 for the 2 sets. $1850 shipped or picked up from Denver Colorado. Again these are used calipers that have a couple small blemishes that I’ve tried to show in the pictures. If you want a better pic of something please ask. More info on the calipers can be found here https://www.superbikeunlimited.com/beringer-100mm-108mm-aer… These will be posted on other forums.
