What sort of riding do you want to use it for? On really heavy going, Ohlins shocks don't have a good reputation. I hate to use it but see The Long Way Down for an example... 3 shocks blown out in one day. My friends Chris and Erin Ratay had repeated shock failures on their way up through South America, on both their bikes, after getting custom built Ohlins fitted to their bikes. In the end they reverted to the standard BMW shocks, which really are not great either but at least did not suffer from mechanical failures.
I'm sure there are plenty of people who are happy with their Ohlins, but this is my personal experience, as it was me that had to box up and freight the Ratay's original shocks and send to South America from NZ.
