    Vintage motorbike - BMW R75/5

    Iím currently considering acquiring a vintage motorbike, a BMW R75/5. It has had a full nut and bold rebuild several years ago and appears extremely clean with quite low miles. I have a 2016 BMW GS 1200 but an older bike is appealing as I would hold it long term. In reality it would get limited use, the odd Sunday run out etc so no more than 1,000 miles per year.

    Does anyone have experience of these bikes, are they easy enough to maintain?

    Thanks

    Pop over onto Ukgser and look up a guy called Mikeyboy. He is an airhead specialist. I donít believe there are many horrors with these. Unleaded valve seat mods plus usual work on the final drive.

    Please post some photos when you get them

    Easy to maintain and great to modify.

    I have a 1975 R90/s that I have owned for over 20years but have not done more than about 20k miles on it in that time.
    Many upgrades/mods are possible and mine got a fair few when I rebuilt it all those years ago.
    I have had problems recently with "ethanol" modern fuel. BM's of this age left the factory with a red oxide coating inside the fuel tanks and the latest fuels attack the coating and fill the carbs with red gunge!
    Most tank lining products are risky if you are not intending to have the paintwork redone.
    The only thing that I would check is if the R75 is a SWB or LWB model. The earlier SWB could be a bit twitchy I believe.

    Thanks for the replies. The bike I was interested was a SWB model but after some research, think Iíll keep an eye out for a LWB.

    Nothing wrong with /5 , apart from the pain in the arse slide carbs.

    I prefer the 90/6 model.
    I've been in business for 30 years looking after bmw's and have almost one of every model in my collection :D..

    I think this requires its own thread, with plenty of pictures of each.

    I think if Neil (step toe) posted his collection of bikes up here there would be a LOT of soiled undies, the man is a legend in the BMW world.

    Come off it - 30 years - don't you mean 50 - lying about your age again

    I've had a few - nice bikes, but I thinking "pinking" comes to mind - certainly with the 60/5 - even with "lead additive(s)" - by the way, can you still buy "lead additive" these days - still got a couple of bottles, (plastic), in the shed

    I drive a R80 ST (modified) and a 1200 GSA and there is no competition between both, the modern one is a comfy long haul bike and everything is easy on it. The old beemer is so much more rewarding when finding a good line (the square Avon tires are long gone ;-), working the scary brakes when the bend approaches quick and its quite hard on the suspension. If I would have to decide in a one bike only situation, I`d keep the airhead. The /5 would be my choice just because of the nicer front light/speedo combo than the /6.

    The 60/6 was renowned for pinking, there were base gaskets available to lower the compression to help with the pinking.

    It is easy to maintain and you no need to have mechanical know-how of technician to perform simple-home tasks, some decent tools and a little common sense are you all need to keep your bike in shape. Always check enough gas and choose the best oil to maintain the engine well, i find it in this link https://www.theriderbase.com/best-motorcycle-oil/
    Try to take one and have more experiences of it. Good luck to you.
