Motorcycles With Car Engines: A Brief History of Two-Wheeled Absurdity

By | General Posts

In their own way, each of them is outrageous. But some are more so than others.

To make this list, the resulting car-hearted bike needs to have been a streetable production model, although some were series production and some were conversions or customs built in bulk. There are plenty of one-offs out there with even wilder engines than these, but we’re using this criteria to pare things down.

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

By | General Posts

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 partnered with the likes of Roland Sands Design and Mustang Seats to offer factory-approved accessories to help make the R18 more your own.

Unlike the R NineT, the R18 features multiple ride modes which include Rock, Roll and Rain. The former being the most aggressive ride mode, with access to the bike’s full power and torque. Roll mode is analogous to most motorcycles’ Road mode, while Rain offers softer throttle response and more limited power and torque.

The bike’s suspension is pretty neat in that it looks very much like a hardtail (aka no rear suspension) but, in fact, is merely hiding its rear suspension bits. The bike’s front fork legs are each a whopping 49 millimeters in diameter and look suitably old-timey — though I’d have loved to see a modern BMW interpretation of the classic Earles fork design that it used in the 1920s and 30s.

The R18 will be available in two flavors at launch: the standard version and the First Edition, and it’s the latter one that really gets my attention. The First Edition pays the closest homage to the classic Beemers with all kinds of pinstriping and chrome. It also comes with some neat extras like historically accurate tank emblems, slotted screws (to look period correct while also annoying your mechanic), a leather belt, a screwdriver, gloves and a book celebrating the BMW motorcycles’ 97-year history.

The standard R18 will set you back a surprisingly reasonable $17,495, while the First Edition will go for $19,870. Bikes are currently slated to hit dealers later on in 2020, but given the dramatic effect that the coronavirus outbreak has had on the industry, that could be pushed back.

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

By | General Posts

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 customization program there includes parts from Roland Sands Design, Mustang Seat, or Vance & Hines.

Full details on the BMW R 18 can be found in the press release section below.

 

Stripped Down Harley-Davidson Muscle Bike Is the Treat to Wait for in 2021

By | General Posts

by Daniel Patrascu from https://www.autoevolution.com/

Despite the fact that it is probably the world’s most famous motorcycle brand, Harley-Davidson seems to be struggling to come to grips with the realities of the age. Plagued by financial problems, Harley recently lost its CEO, and more stormy weather seems to be looming ahead.

There are however plans in place for a turnaround. These plans cover everything from new models to the reinvention of the dealership network.

As far as new products are concerned, we already talked about the two new motorcycles Harley plans to launch by the end of this year. Both – the Bronx and Pan America – are built on a new middleweight platform and use new Revolution Max family of engines.

But perhaps more exciting than anything is the return of the bike maker to the custom scene, with a yet unnamed motorcycle announced for 2021.

Previewed at about the same time with the other two, the custom machine is described as one with “a muscular stance, aggressive, stripped-down styling and 1250cc of pure performance.”

Officially, that’s about it when it comes to this product fom now, but by the way it looks (see in the gallery above) and given the fact that the Pan America will use the same 1250cc Revolution Max engine with 145 hp and 90 lb-ft of torque, we expect the specs on the custom to be even more extraordinary.

All the bikes we mentioned here are part of a plan meant to reinvent the company by 2022 and increase the number of Harley customers by 1 million by 2027, for a total of 4 million in the U.S. alone.

“The bold actions we are announcing today leverage Harley-Davidson’s vast capabilities and competitive firepower – our excellence in product development and manufacturing, the global appeal of the brand and of course, our great dealer network,” said in a statement back in 2019, when the moves were announced, Matt Levatich, at the time the company’s CEO.

“Alongside our existing loyal riders, we will lead the next revolution of two-wheeled freedom to inspire future riders who have yet to even think about the thrill of riding.”

BMW R 18 Motorcycle with Monster Big Boxer Engine to Be Unveiled on April 3

By | General Posts

by Daniel Patrascu from https://www.autoevolution.com

It’s been a long time in the making, but BMW Motorrad’s newest entry to the cruiser segment, a bike aptly called the R 18, is just around the corner. On Friday, April 3, the Germans will pull the wraps off what is to become one of the most potent motorcycles in its segment.

And this bike owes it all to a new engine BMW likes to call the Big Boxer. First shown on a bike called the Concept R 18 at the Concorso d’Eleganza Villa d’Este in May 2019, the engine moved over to two custom builds, before getting the official thumbs up at the end of 2019.

The two-cylinder powerplant has a capacity of 1,802 cc, which should make it the highest-capacity engine ever used on a production motorcycle. According to the specs revealed by the Bavarians, the engine has a power output of 91 hp and 158 Nm of torque, and that should also make it the most powerful boxer ever built by BMW.

It’s the R 18 that will see the first application of the Big Boxer, and on the bike it will be linked to a single-disc dry clutch that sends torque to the 6-speed transmission. Although the power ratings have already been announced, the performance specs are still unknown.

“All of us at BMW Motorrad are very much looking forward to the absolute highlight of the year for us – the world premiere of the BMW R 18,” said in a statement Dr. Markus Schramm, Head of BMW Motorrad.

“BMW Motorrad achieved record sales for the ninth year in succession in 2019. With the R 18 and the associated entry into the cruiser segment, we are consistently pursuing our growth strategy with the clear goal of becoming the number one in the premium segment worldwide.”

More details and official photos of the bike will become available at the unveiling.

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

By | General Posts

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 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.

BMW Motorrad says ‘Big Boxer’ is its most powerful boxer engine ever
by Sven Gustafson from https://news.yahoo.com/

BMW is dishing new details on the newly developed but throwback-style 2-cylinder boxer engine that features in four Motorrad concept bikes unveiled over the past year that look increasingly likely to presage production motorcycles.

Dubbed the “Big Boxer” by BMW, the 1,802 cc (1.8-liter) flat-twin features in the Concept R18/2, shown earlier this month at EICMA, the Concept R18, and the Motorrad-suppported concepts the Departed by ZON and Revival Cycles’ Birdcage. It’s said to be the most powerful BMW boxer engine, making 91 horsepower and 116 pound-feet of torque and is said to balance high pulling power and running smoothness.

BMW says the engine harkens to the first air-cooled Motorrad boxer engines that debuted in 1923 and stayed in production for about 70 years, with the same overhead valve drive and separate engine and transmission housings and built to be reliable and easy to maintain. but the new Big Boxer is air- and oil-cooled, of course, and the quenched- and tempered-steel crankshaft has an additional main bearing at the center to prevent against unwanted bending vibrations in the large-volume cylinders. It also has a vertically split aluminum engine housing. A wet sump lubrication system supplies the lubricating and cooling oil via a two-stage oil pump and a sleeve-type chain driven by the crankshaft.

It was also inspired by the 2-cylinder engines of the R5 and R51, from 1936 to 1941, and the R51/2, from 1950-51, that featured two camshaft driven by the crankshaft via a sleeve-type chain and similarly positioned to the left and right above the crankshaft. That makes for shorter pushrods and reduced moving masses, among other advantages, plus improved precision and higher speed stability. Rather than employ modern hydraulic elements for valve clearance, the new engine also borrows the legacy Motorrad boxer method of employing adjusting one screw and a lock nut for each steel valve.

The transmission is a constant mesh six-speed, with a reverse gear available as an option, and torque transmitted to the rear wheel via a propeller-shaft or universal-shaft drive. Both the propeller shaft and the universal joint are nickel-plated and open in another wink to Motorrad history on models through 1955.

Hennessey’s Venom F5 engine bench tested at a furious 1,817 horsepower

By | General Posts

by Loz Blain from https://newatlas.com

It’s only been live for a week, but we’ve already had to update our list of the world’s most powerful cars, after Hennessey Performance surprised itself with an extreme dyno reading.

The Venom F5 is the car Hennessey hopes will demolish not only the fastest production car record now held by Bugatti, but also the 0-400-0 record recently reclaimed by Koenigsegg. With a long enough piece of road, there’s every chance this wild machine could be the first to break 500 km/h (310.7 mph), which is the next nice round number to aim at since the Chiron hit 300 mph (483 km/h) last month. That’s if Koenigsegg’s Jesko doesn’t get there first.

To claim the record, the Venom will need power. Lots and lots of power, to fight through the massive force of wind resistance you get at speeds more than four times faster than highway limits. Up until this morning, Hennessey was saying the Venom F5 would make some 1,600 horsepower, a truly staggering total and enough to place it equal fifth on our list of the most powerful production cars available, alongside the Jesko and the Chiron Super Sport 300+.

But the engine hadn’t been dyno tested until now. And while 1,600 horses was the target, even John Hennessey himself appeared surprised with the bench test readout of 1,817 hp and 1,193 lb-ft (1,617.5 Nm) of torque.

“We exceeded our target horsepower number. Actually, we blew our target number out of the water by delivering over 1,800 horsepower,” said Hennessey. “The F5 engine has a very broad power band with over 1,000 lb-ft of torque available from 2,000 to 8,000 rpm. Give it the full throttle and it’s the most furious engine that we have ever built. Thus, we gave our F5 engine a special name: ‘Fury.’”

Fury indeed. Check out the rage in action on the dyno below, and imagine that sound happening when you put your foot down in a lightweight, sub-3,000-lb (sub-1,361-kg) hypercar.

And how might you squeeze 1,800 hp out of a 6.6-liter, twin turbo V8, you might well ask? Well, Hennessey has seen fit to publish a detailed set of components and specifications, which we have reproduced in full below.

Hennessey Venom F5 V8 Engine Specifications:
