These are near perfect. They have never been used. There are a few minor scuffs from shipping that are not visible when mounted. These are about as good as you can get. Upper clamp is 50mm. Lower is 54mm. There is one spacer to to covert the 32mm axel hole to 29mm if needed. The bracket for the calipers is changeable and you can install any bracket you like from OHLINS . The included brake caliper brackets have a 62mm bolt distance (not radial). The original stickers for the caliper brackets have "SUZ" which might mean Suzuki. These are what Ohlins considers "universal" so you can get different caliper brackets from Ohlins USA. I think the spring is .95 for rider weight of around 175LB if im not wrong but its not for sure. 1290$ SHIPPED!!!!!
