I highly recommend talking to Ted at Beemershop.com in California. He's really passionate about BMW and suspensions and will talk as long as you need him to explaining your options and letting you know what's out there based on your particular wants. He spent 45 minutes on the phone with me when all I was looking to do was set preload and rebound on my stock Scrambler before trying to sell me any upgrades. He's sold me some upgrades to previous bikes and I really trust the guy.
