I recently picked up a second hand BMW G60X-Challenge with a brand new Hagon coil shock installed (the bike previously had an Ohlins but the guy I bought it off wanted to hang on to it). Since then I have put less than 30Km on the bike before the shock blew - leaking oil and no dampening. As the shock was new I rang up the Hagon distributer about having the shock repaired under warranty. The Hagon rep has asked me to send the unit to him to be inspected but also told me that the most likely cause was running a unbalanced rear wheel which may not be covered under warranty. The only time I've ever seen a rear shock blow has been under extreme riding or on a vintage bike so this all seems a bit strange to me. Has anyone here ever had a similar situation?
