I fitted first Migsel and then SW Motech lowered pegs on my 1100GS, both of which put the pegs lower and slightly further forward. I fitted an adjustable Touratech gear lever so that there was enough space to get my boot under the peg, and then I made up a longer connecting rod so that I could lower the lever. I found that the o/e rod end fouled on the silencer slightly so I substituted a rose joint.
For the brake I just had a section inserted into the lever to bring it forward, there is enough adjustment in the connecting rod to put it in the correct position.
