Triumph estimates nearly 50% of all their bikes with Ohlins will be affected and they are sending out notifications to registered owners. They are asking that you go to this Ohlins site though to check prior to scheduling a service appointment.
Well that's just great. Mine falls in the vin range. Nice to find this out only a couple weeks after setting my suspension. I wonder if they'll let me do it, it would make getting the spring measurement easier if it is done off the bike anyway.
