Selling a used Penske Double pulled from my 08 R6, I used it for about a season, never had any issues just decided to change my suspension setup. Currently has a 600 spring on it, setup for around a 170lb rider at the mid to pointer end of the pack. I will also include a 550 rear spring as well. Looking to get $650 shipped to the lower 48 with a spare spring. I will also have it at the CCS Summit Round next weekend.
