This is a Captive racing rear wheel spacer set produced by our friends at Fast Frank Racing. RC 390 has 3 rear wheel spacers, one on the brake side and one on each side of sprocket carrier and all 3 are made of heavy steel and the inner one on the sprocket carrier is very loose and allows the sprocket to move around (not good). All 3 FFR spacers are made from 7075-T6 alloy for a very precise fit, and they will not fall out. Captive spacers are Legal for the RC390 Cup Series in Moto America so if you're one of the lucky ones, pick yourself up a set.
