BMW’s prewar-inspired R18 boxer motorcycle makes its production debut

General Posts / By

by Kyle Hyatt from https://www.cnet.com/ We loved the concept at Villa d’Este, and now the production version will haunt our dreams until it’s released. I’ve been looking forward to a production version of BMW’s R18 concept since it debuted last year at Villa d’Este, and now it’s finally here. How close does the production model get to the utterly gorgeous prewar-inspired concept? Well, pretty close, actually. Sure, there will be plenty who argue that it should be closer, that the production bike’s front wheel is too small or that BMW should have retained the concept’s fork covers, but I’m not one of those people. This thing is a handsome-as-hell cruiser-bobber style motorcycle, and I badly want to ride it already. The R18’s headline feature is its massive 1.8-liter horizontally opposed twin-cylinder engine. This is the biggest boxer that BMW has ever offered — by over half a liter — and it’s still air-cooled. This lump outputs a 91 horsepower and a whopping 116 pound-feet of torque. It’s got four valves per cylinder with dual overhead camshafts on each cylinder, and it promises to be a characterful old thing, in the best traditions of the brand. The bike also features the classic BMW boxer large single-disc dry clutch and a six-speed gearbox. Unusual for the BMW though (these days, at least) is the decision to leave the bike’s driveshaft exposed. This was done in homage to the prewar Beemers like the R5 and R51 from which the R18 takes much of its inspiration. A reverse gear ala Honda’s Goldwing is available as an option. The R18 is probably closest in spirit to the R NineT, at least as far as current production motorcycles go, and like that bike, it’s been designed with easy customization in mind. To that end, BMW has […]

BMW Goes After Harley-Davidson with Stunning R 18 Big Boxer Cruiser

General Posts / By

by Daniel Patrascu from https://www.autoevolution.com Despite being at the top of sales charts in the motorcycle industry, BMW hasn’t had an entry in the cruiser segment since the R1200 RC . That changed with the introduction of the brand new R 18 this week. Featuring the Big Boxer engine, the “most powerful 2-cylinder boxer engine ever used in motorcycle series production,” the R18 is described as a bike that blends the classic lines of older BMW bikes with modern day technology. The design of the motorcycle, and parts of its construction, like the rear swingarm, are reminiscent of the R 5, a bike designed way back in the 1930s as the first BMW motorcycle to use a foot-operated four-speed gearbox. Cues to that resemblance are also the double-loop frame, the pear-drop tank, the open-running driveshaft, the pinstriped paintwork, and of course the exposed drive-shaft. At the center of the motorcycle lies the Big Boxer BMW has been teasing for more than a year now. The 2-cylinder engine is 1,802 cc in displacement, develops 91 hp at 4,750 rpm, and provides a maximum of 158 Nm of torque at 3,000 rpm. The motorcycle comes with three driving modes – Rain, Roll and Rock – and is equipped with automatic stability control (can be disengaged) and drag torque control as standard. Optionally, reverse assist and hill start control can be specified. BMW did not announce yet when the motorcycle will become available and how much it will charge for it. When it hits the market though, it will be available in First Edition guise, adding a few unique extras like a classic black finish with white pinstriped paintwork, chrome highlights and First Edition badges. Additionally, for the U.S. market BMW partnered with several companies to give the bike a local flavor. The

BMW Unveils The Secrets Of Its New 1,800cc Boxer

General Posts / By

by Sabrina Giacomini from https://www.rideapart.com 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 engine weighs a staggering 244.3 lb—including the transmission and the intake system. 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
