I find the seat to peg distance to be a bit snug on my knees, so I purchased a peg lowering kit from Suburban Machinery. They also offer a modified shifter (lengthened) for $140. One of the websites stated that only 50% of their customers required the modified shifter.
Guess I'm in the other 50%!
The kit lowers the pegs and moves them forward, the distance at the shifter is only 4" from the peg. The brake side is OK once I adjusted it down, but it was real difficult to get my foot under the shifter. I took a measurement from my K sidecar rig, it also has lowered pegs.
I remembered I had scavenged a shifter from my wrecked K bike.
The K shifter attached to the cast arm, so off came the shift peg.
Hole was drilled and tapped
I cut a V into the cast arm to match the back of the K shifter.
The finished product, within 1/4" of my K bike setup.
My knees are happy and I can shift comfortably!
I just looked up the shift lever on MAXBMW fiche, HOLY CRAP!
