- This shock was refreshed March of 2017 by Doug Cornett at Dynamic Motorsports and it has only seen 2 track days. - Comes with 3 different springs for 150 lbs to a 230 lbs rider. Each spring is valued at $100+ and is included in the sale. - Asking for $650 including shipping to lower 48 states. I also have additional stock parts for the bike since it is now a dedicated track bike.
