1800GS coming in 2021?
« on: November 30, 2019, 06:14:08 am »
BMW is working on the development of its biggest Boxer engine yet. The details surrounding the new engine, however, have been scarce, despite the manufacturer showcasing not one but two concepts built around the engine. The House of Munich has managed to keep the mill’s specs secret. Until now. The company has finally opened up and shared the details of the new engine. Here are the big lines.

We got our first look at the Big Boxer in December 2018, when the 1,800cc mill showed up in the R18 Departed custom design presented at the Yokohama Hot Rod Custom Show. It then popped again in Revival Cycles’ birdcage bobber custom. BMW finally came out with its own design in May, dubbed the R18 Concept.

We now know that the model is heading for production and that it will launch sometime in 2020. Until now, however, the engine that underlines the new big German cruiser has remained a bit of a mystery. The displacement and the number of cylinders were the only available specs. Not anymore! We now get a full portrait of what’s going on inside the massive block.

First off, to be specific, the engine’s displacement is 1,802cc rather than the round number it’s been referred to for the past few months. The two cylinders have a 107mm bore and the aluminum pistons, a 100mm stroke. The block alone weighs a staggering 244.3 lb—including the transmission and the intake system.

BMW 1,800cc Bower Engine
The engine’s over-head valve with dual camshaft set up is inspired by BMW’s early Boxers like the one found in the 1936 R5. To avoid excessive vibration of the crankshaft caused by the cylinders’ massive volume, an additional bearing has been added at the center of the shaft.

What about power figures? We have those too! The new ginormous Boxer is expected to produce 91 horsepower and 116.5 lb-ft of torque at 3,000 rpm. BMW adds that the engine will max out at 5,750 rpm.

Availability of the BMW R18 (provided that will remain the name once it hits production) has yet to be announced.

For those of you familiar with all the technical lingo, I have joined the full BMW press release if you want to learn more about the finer details of the new engine.

If they could build the rest of the bike out of titanium and helium composites, why not    :imaposer: :imaposer: :imaposer: :imaposer:

Yes, correct - and for 1 reason only, which is to be able to compete with in the US Cruiser market.
Quite frankly I don't see this behemoth used in a GS, because then 'whale with tits' will take on a new meaning.
For the yankees though bigger IS better, and if it only revs to 2000 rpm then that's great  :thumleft:

I still love my R 80G/S with 36 kW for the real tough stuff and my R1150GSA for mostly dirt highways etc ...
1800 cc is madness in my world of requirements and needs ....

I many times while travelling somewhere in the continent unabashedly envied the locals on their +-150cc bikes. What I would have given then for a small bike. A horse, a horse! My kingdom for a horse!

Run 2 keg lines through that motor and you have a very cool Tap mount for draught

The advantage is that current GS's is already as heavy as a 1800......HiLux.

When I first saw the designation 1800GS, I automatically thought, "Great, if they can make it the same weight as the 1200/1250's or even less, and with about 160 - 180 horses."

My mind just works that way, but of course I should know better. Today's thinking, don't give 'em more power, give 'em more torque instead. Then add an electronic torque limiter so they can't use it.

And charge what? 400 grand?  500??  ???

This is going to far now, why dont they just put in a 4 cyl Porsche boxer engine in it , 2,3 L or 3.4 methinks.
 The cars engines are getting smaller and bikes the other way nowadays lol

But the Yamaha and the Triumph are real bikes. :pot:

Ja, Chris, I cannot help myself.....but this going to 1800cc for the cruiser market makes sense, as a small capacity cruiser just does not feel the same as the big lazy revvers with lots of

low-down torque to pull high gearing.
