School me on BMW models

Im reading models such as R50/2, and R75/5 and I have no idea what it means!

Ive tried looking on the net for an explination but have had no luck. Could one of you more educated types please teach me something?

Here is a link to Phil Hawksley's excellent BMW information site which hopefully should clarify thing a little. Basically anything starting with an R is a flat twin engine. The 50 or 75 tell you the engine size in these cases 500 and 750cc and the /2 or /5 is the series, the latter running between 1969 and 1973 when it was replaced by the /6, up to the /7 which ended in 1979 when things changed and they dropped the series number.
There are exceptions such as the R25 which is a single cylinder 250 and the R69 which is the sports version of the R60/2, there are other exceptions and they are listed here.
I hope you find this useful.

the first number is the engine size and after the slash is the model designation.

/6 onwards are where they get usable (and affordable) as day to day machines.

good rundown here http://en.wikipedia.org/wiki/History_of_BMW_motorcycles

Ahem , the /6 and later models is also when BMW started using plastic for cosmetic purposes and added more expensive and less field repairable components like; hydraulic brakes, electronic ignitions and other completely unnecessary stuff (I mean clocks, WTF??) Give me points ignition, tube tires and spoke wheels and I will ride around the world all day any day!

Do I take it you're on of those /2 riding hippies or one of those white knuckle /5 riders who take 50 yards to stop from 30 Mph with their old school drum brakes

All you need to know is /5 is 1970 to 1973. /6 is 1974, 75 & 76. /7 starts in 1977. That's it. Everything that comes before this is an antique, we like them but nobody rides them and everything that comes after is modern crap.

Rob, I get the impression you've never ridden a /5 with properly adjusted and updated modern brakes? I can out stop a /6 with single disc any day (unless you're talking about my '74 R75/6, upon which I've actually done a "stoppie"...)

it's all tongue in cheek BB nothing serious. I've ridden /5's with very, very bad brakes and one or two with decent ones. I know you can get them to work well but unfortunatly most seem to be neglected when you buy them. For a potential new owner without airhead experience it's a lot of hassle to start fettling brakes as soon as you buy a bike.
