GP Suspension, 25mm Cartridge Kit for Yamaha R1 2015-2022 & R6 2017-2022. This New Kit was dropped into a set of forks that were a back up set which cost $1399 brand new, only used for a few sessions one weekend. Only selling as I needed the Fork Tubes, which I’ll be dropping my Öhlins Cartridges into them. Absolute Steal for $1000 shipped.
