Shock swap 1200 Speedmaster

Hi folks. I have a suspension upgrade on order, a wilbers rear shock and front springs and oil. Just wondering, has anyone changed their rear shock on a 1200 speedmaster? It looks a lot more involved than on the bobber. Are there any shortcuts? Thanks

Sorry I can't help you there, but I am very curious as to why you are upgrading both front & rear, and what gains/benefits you are expecting from each one? And what research led you to this decision?

Oh, and how much for them? Same as BMW? $1,400.00 for front and rear?

TIA!

Looking for better damping and spring rate, particularly when I've got a passenger. The standard suspension isn't too bad but I like to have it a bit tighter. Shock and springs all up (without fitting) $1000 Australian dollars, which is probably about $700 US. Not installing valves in the front at this point. It's really the only performance I'm making to the bike, I'm finding everything is pretty good. I think if I was only going to be riding it myself I probably wouldn't bother too much. The feedback on the shocks on the Bobber forums is excellent though, and the price is pretty good I thought.
Looking at the set up, I was concerned I'd have to remove the rear guard to get at the rear bolt, but as the air box needs to be removed to get at the front bolt, I think that would give me enough space to get at it on the inside..

RevKen -

Gotcha. Got my daughter on a new Bobber in '17, she kept in my garage a year so I rode it a lot- one-up, suspension is fine.

So you are saying two-up on the SM, is that even the pre-load adjustment on the bike is insufficient two-up?

Not a concern of mine as I won't be riding two-up on the SM.......that's what my '09 CVO Road Glide is for - puts them to sleep behind me.......
