It is no secret that in South Africa we ride BMW motorcycles off road* even when they were never intended for that purpose. Most of these riders are GS owners.
* I mean radical off road stuff – like jeep tracks, mud holes, deserts and dry river beds.
Occassionally standing around the braai fire (barbeque) the average modern GS owner wonders about the other R series BMW boxer engine products. Here is a quick overview so the other guys dont laugh at you . . . ( launch year followed by model).
The R Series boxer story broadly breaks up into two eras i.e. 2 valve and 4 valve.
Two valve era – R Series
1923 – R32 – This motorcycle, and all the R models that followed, are identical in concept – all the way to the 2009 R1200 – a period of 85 years. Two cylinder, opposing, air cooled, crankshaft in line with the direction the bike travels, dry clutch plate like a car and a final drive shaft – together fondly called the boxer engine.

ADDITIONAL NOTES:
K Series launched during the 1980’s featured a completely different engine and is 100% a road motorcycle i.e. the 3/4 cylinder water cooled engine.
F Series launched in 1994 featured a single 650cc cylinder chain driven Rotax engine with a wet clutch. Modern versions of this motorcycle include the 800cc and two cylinders.
G Series launched in 2006 features motorcycles with smaller engines i.e. 450 and 650cc. These motorcycles are super motards or street legal enduro off road models.
S Series is the new Sport series intended to compete with the best that Japan has to offer.
HP2 is not part of the R Series but briefly included above for convenience as it makes use of the same engine.
