I had my dealer replace my rear shock with the BRP "2 up" shock. Item 1, I have never in more than 50 bikes replaced a shock -- not less in less than 2000 miles! Item 2, this is the shock the bike should have come with! Item 3, I could not justify the after market price for replacement shocks. Item 4, the bike handles much better and does not drag over speed bumps. The best $200 I've invested.
