I have a set of 26mm risers that fit the strom. I'd say they will fit with the standard brake lines but mine are braided and a little shorter than standard.
the risers fitted but only comfortably after I dropped the forks a little more.
I took them off after a few days.- I liked the extra height when standing on the pegs, but not while sitting... I felt like I was riding a Harley with ape hangers and my wrists started hurting after 10 mins.
So some people like em, I don't. But when I fitted the things to the Deauville they stopped the pain in my bad back, and the same on the CX500ec.
