Hello
I'm considering the purchase of a '76 R75/6 that has a '78 R100RS motor & gearbox fitted. The seller has completed a very thorough paint and mechanical overhaul of the bike's engine, gearbox, wheel bearings etc, including upgrade to brakes (2 x cast iron PFM brake discs as per '74 R90S + handlebar mounted brake reservoir) to provide greater security vs the greater engine power. I am informed (though stand to be corrected) the "6" frame has the identical dimensions to fit the transplant of an R100RS motor/gearbox.
I'm not concerned about the mix and match of components and would use it as a weekly ride, though would very much welcome any feedback/ observations on such a bike, more so if you completed such a "transplant" or have ridden a similar example.
cheers
Patrick
