My Suzy is currently in the workshop, engine off etc. so I took a good look at the frame and asked the mechanic "why don't we fit 'normal' foot controls and leave the forward pegs as highway pegs?"
It definitely would improve both ride quality and bike control in city driving (Europe-wise, at least).
He pointed out that unless there's a way to tap into existing bolts (such as, engine to frame) there's so much work to be done I might as well manufacture a new frame altogether...
(Now this is where BMW and Guzzi designers show their wisdom... the frame is made of a top half and bottom half bolted together by awesome mighty bolts; the top half is generally the same on all models, then cruiser, GT and sports bottom halves differ for footpeg and other fittings moving +/- front or rear)
Sooo... I'll look at the frame again next time I go, one thing is to manufacture a looong floorboard front to rear, another is to actually move the pivot points of brake and gear pedals.
