frame mtg points R1100 vs R1150

[arbalest]

On the engine casings, how different are the frame mounting point castings? Will a Trip Teq sidecar subframe for an R1150 fit an R1100? Or can it be made to fit?

The back end of the gearbox is quite different. Look at the area around the footrest mountings on both bikes and you'll see what I mean.
