• It has been widely speculated that BMW may debut a new 1254cc Boxer engine.

• The new engine had been expected to power the new R 1250 GS and R 1250 RT only.

• But CARB has revealed it will power the entire “R” series.

First and foremost, BMW will reportedly introduce nine new models for 2019, but the biggest news is of course that there is a big possibility of a bigger capacity Boxer engine, hence a new R 1250 GS, which had been speculated since May this year when a new R 1200 RT was spied while undergoing road tests. Now there is also news of the new engine powering the entire Boxer line-up.

BMW R 1250 GS to be Released in 2019?

The news leaked through filings with the California Air Resources Board (CARB), California’s emissions watchdog department, revealed that BMW will drop the new 1254cc Boxer into five new models. The news has surprised us as we had initially thought that it would only be installed in the new R 1250 GS and R 1250 GS Adventure, and perhaps the R 1250 RT.

In addition to the three mentioned models, BMW has filed for the R 1250 RS and R 1250 R.

The 1254cc horizontally-opposed-Twin engine, better known as the Boxer engine, is rumored to feature variable valve timing for the first time for BMW. Power output is also speculated to hover around the 134 bhp figure. Besides that, the engine will pick up some weight.

The updates will mark another big step in the evolution of BMW’s venerable Boxer engine since becoming liquid-cooled in 2013.

There is no news regarding the R nineT range which is powered by the previous generation oil-cooled Boxer, though. In 2020, maybe, since the Euro 5 standard will begin from that year?

We foresee small updates to the designs and perhaps chassis of the new bikes, since the main update is the new engine. We are expecting to see the new models at the Intermot show in Cologne, Germany next month.
