    Default 1974 BMW R90 Critique

    I am looking for a correct original bike that I can enter into AMCA judging that hasn't got a lot of major faults but I know zero about BM's. I was hoping that I could get some feedback on the attached photos and some guidance as to what I should be looking for. I have also posted photos of A BMW R75/5 on a separate thread for similar feedback.

    Would be interested in a comparison as to the preference of someone who has knowledge of both models as to which would be the better touring bike.

    Hope that someone can help.

    I have both a 1971 R75/5 and a 1975 R90/6. The /6 is more powerful and more stable than the short-wheelbase /5. the /5 engine is smoother running than the /6. I bought the /6 new. From the factory the front forks on both bikes were spongy and needed to be upgrad to be more stable. I've toured most of the US on the R90/6. It has never failed to get me home. From new I've rebillt the top end twice, replaced the starter, replced the timing chain and gone through three clutches. That's it.
    Good luck with your decision.

    Ted, I think what VL is trying to determine is if the bike(s) he is looking at look correct. He wants to make sure he is buying a bike suitable for AMCA judging. Do you see anything that look incorrect? I know its hard to tell just from photos but more than anything he just wants to make sure all the major components are correct. Thanks for your input Ted.

    Mufflers are aftermarket, plug wires, shocks.

    Keith,

    The R90/6 is a good looking bike. Overall the bike looks correct. Without more detailed pictures I can't tell much more than the bike has been nicely restored and should score well in AMCA judging.
    VL asked which bike would be good for touring. While I prefer the R90/6 for long trips, properly prepared both bikes are good tourers.
