BMW is marching steadily toward its promised cruiser, anticipated sometime in 2020, with the news of its latest concept bike based around the new 1,800cc “Big Boxer” opposed twin. Buried in a press release for a new Concept R18 /2 (pronounced “slash two”) were photos showing the design and production of the /2, including the most detailed shots to date of the new engine, clearly functional and roadworthy.

First, the bike. The Concept R18 /2 appears to be a classic cruiser in design, with modern flowing lines, a small headlight cowl and a slightly bobbed rear fender. Wheels are cast, 19 inches up front and 16 at the rear, with Brembo brakes and a gorgeous Candy Apple Red paint on the bodywork.

The Concept R18 /2 has a hidden rear mono shock for a classic hardtail look.

The 1,800cc air/oil-cooled boxer engine used in the /2 has a classic BMW 1960s aesthetic, finished in matte gray and black. The massive cylinders protrude past the ends of the handlebar, and dual air intakes funnel under the rider’s thighs to the airbox beneath the front of the seat. To the rear of that is a hidden single shock absorber to maintain the classic hardtail look.

We’re not quite sure why BMW wants to try breaking into the American cruiser market, given lackluster sales in the segment (and its own ill-fated R 1200 C attempt in the late ’90s/early oughts). Hopefully plans include a bagger as well…but in any case, we’re excited to see and hear more about this new R18 Big Boxer engine, clearly headed for production in the near future.

  1. “We’re not quite sure why BMW wants to try breaking into the American cruiser market, given lackluster sales in the segment…”

    My thoughts exactly. Only thing I can come up with is that it’s a warning shot across Harley’s bow: “If you’re gonna play in our sandbox (upcoming Pan America 1250 ADV bike), we’re gonna play in yours.” Other than that… beats me what this bike is for.

  2. meine liebe,

    So much effort to produce a Low Rider S, with the heartbeat of a sewing machine. Now you weirdo architect techie types, don’t be a haters, admit that imitation is the highest form of flattery.

  3. I like it, great styling, much like the older Yamaha Warrior. Comes down to price and reliability. Depending on price, If I wanted a hooligan bike most likely buy the king of hooligan muscle bikes, the V-Max. Only trouble with the V max I owned is that it was so fun I just knew I was going to start knowing the local deputies on a first name basis.

    The Beemer muscle bike looks great, however it needs stylish and functional guards for those massive jugs. Just saying, first time is falls over it shouldn’t cost $1,500 just for a rocker cover. The other issue is if the final drive will be beefy enough to handle the torque as the miles rack up. BMW has never been renowned for strong trouble free final drives.

    Stop with any hate mail, I am just playing devils advocate, saying what most of us are thinking. Beautiful bike. Much like a good woman, you know if the bike is right when walking away, you just have to turn and give it another look.

  4. How quickly the mighty have fallen.
    Concept one has all the hallmarks of a classic. Concept two has all the hallmarks of a Harley.
