We knew for the 2019 model year that the R1200GS would become the R1250GS – the venerable adventure-touring machine getting an engine upgrade for the next model cycle. With 1254cc of displacement, and rumors of variable valve timing, it was of course inevitable that BMW Motorrad would bring its new boxer engine to the rest of its “R” line. We just didn’t think it would be all at once

Tipped by filings with the California Air Resources Board (CARB), we see though that the entire lineup of R1200 motorcycles will be getting a new engine for 2019. This means that the BMW R1250GS, BMW R1250GS Adventure, BMW R1250R, BMW R1250RS, and BMW R1250RT are on the way.
