Review on COPART 2Pcs 8MM M8 Motorcycle Swingarm Spools Sliders For Honda CBR150 CBR100F CBR1000Rr CBR1100Xx CBR125 CBR250 CBR400Rr CBR450Sr CBR600Rr CBR900Rr Motorcycle & Powersports by Christopher Clearfield

Umm so I bought this inert metal (2X). Can't tell if they're cast or machined, but they fit my 2020 CBR600RR swingarm. To be honest the price seems reasonable to be able to put my bike on a stand. They are red anodized and the paint has been scraped off where the stand connects to the reel when first used. It's not unexpected in metal-to-metal contacts and I can't blame him for that. I didn't measure to see if the thickness matched the description but they fit the swing arm and stand u piece so should be the right size. You know, I'm assuming they're 8mm thick.
