None are built in the USA. BMW would never stoop so low. They do however make the X series AWD cars there.
The biggest baddest cruiser the R 1800 flat twin is proudly Berlin built.they are about to release a R2000, yep a two litre twin.
Also a new version of the six cylinder K1600 as a wild 1800 cc.
The biggest selling large bike model in the world is the mighty GS range, now the R1300GS, expensive yes, but sales envied by Harley and Ducati Adventure bikes.
Some of the new small 450 models are built now in China and India using their designs and machines. This makes them as cheap as the competition.
Some of the smallish parallel twins were Austrian built.
As fast road machines, tourers, adventure and racing BMW have been the top of the market for the last 20 years. Now they are tackling the small Learner approved -lams market and will sell a motza.
My current beasty is a 2005 K1200R motorsport, the new hyperbike that year with a mere 167hp, 138 nm and only 214kg. The fastest acceleration for a Bike on the planet, 2.8 seconds to 100, limited by Aero to 280km/h.
The Japanese absolutely lost their minds when a shaft driven bike slaughtered their hyperbikes. Then BMW made a six version to take Goldwing sales for those who wanted actual very high speed touring.
Then the S1000R came out and slayed the race tracks.
Modern R and K shaft driven bikes have none for the rise and fall of the shaft of old generations. Handling and brakes are world class, even a tourer will scare a sports bike rider.
