A forum member ask some questions off list. I realized my response and the links may help others, so am re-posting it here.
I have Ohlins 30mm fork kit up front and a Touratech Extreme rear shock. Both were ordered with my weight and loads in mind thru Jaxon at
Ride On ADV. He's in TX and I did it via email/mail and installed the shock myself. Jaxon was awesome and helped me decide as well as asked all the right questions for weights and riding so things would be built for my needs.
I shipped the forks off to be done, they came back ready to install with the removed parts in plastic. I just used a gun case to ship them. It's better if you can get one with a cardboard box around it, but they shipped it w/o fine at UPS. All in all, it killed about $3k. You can get a nice aftermarket shock, sprung for your weight and lowered for $800-1200. Sliding the forks up in the triple trees 13mm is free.
Wilbers,
HyperPro,
Penske, Yacugar,
Progressive,
Cogent Dynamics and others I have forgotten all offer possibilities for the Super Ten. Progressive and HyperPro specifically mention lowering options.
Ted Porter's Beemer shop, (they work on anything), is one of the most knowledgeable places and Ted will take the time to talk to you, even if you're not a customer. He's a really nice guy. Sometimes super busy and on the road though, so can be slow to respond to email.
Most shops when you order a custom rear shock will help you select what meets your needs, including ride height, if thats what you want. Some aftermarket shocks allow the spring perch to be lowered, others do not. Some shops build special set ups for lowering with shorter shocks. Spring swaps are pretty easy for any good shop to do, though the stock Super Ten shock requires a spacer to fit aftermarket springs in some cases. My stock shock did, in which I ran an 1100 lb spring on my stock shock for nearly 100k before going with the custom suspension.
In my case, I didn't need any lowering. I'm 5'11 with a 30" inseam, but am fine with just a toe down. YMMV.
Nice article those considering lowering might find interesting.
