Imported these from the US a few months ago and were fitted for 2 months although the bike was never used. Researched the hell out of this and these, to me, were a better option than even the Evotech option. While I was buying I also included a replacement puck just incase. Takes approx 20-30 mins to fit and can barely notice them when on. I paid approx £200 including shipping and duty, these are brand new and can’t even tell they have been fitted. https://woodcraft-cfm.com/collectio...2-ducati-monster-937-2021-22-frame-slider-kit £160 delivered.
