Is the shift the same as the Hypermotard?... Ducabike Ducati Hypermotard 950 / SP Foot Gear Shift Lever (conquestracingltd.com)
Just looked at my 939 and the pedal pivot is really close (~75mm) to the gearchange shaft. I'd say it's impossible to alter the orientation without mounting the pegs/lever further back...
Hyper 939 doesn’t have that type of frame nor does it have the distance between the footrest and gear spindle to accommodate that set up. Sorry to be a killjoy. Andy
Apologies for thread interruption, I really should have said it wasn’t a proposed solution to OP’s dilemma, but a clever fix for a similar issue. Photos taken at Spa Bikers Classic where they have a round of the Classic Endurance Championship. This set up caught the eye because it was an engineered solution to having a race shift-familiar rider partnering a road shift-only rider, where changing gear shift pattern needed to be done in an instant as those two riders swapped over.
