How long do motorcycle shocks last?
In general most OEM shocks are shot by about 30K miles or so. Whatever brand shock you use, you are either going to have to replace or rebuild it every 30-40K miles if you want it to continue to perform well. The advantage of aftermarket shocks is that you can have them rebuilt and recharged.
How do you know if your motorcycle shocks are bad?
Symptoms: The ride will feel soft or vague and as speed increases, the rear end will want to wallow and/or weave over bumpy surfaces and traction suffers. Loss of traction will cause rear end to pogo or chatter due to shock returning too fast on exiting a corner.
