Ron Schavrien got into motorcycling, he it from a different perspective most people. He wasn’t a high school student, the latest motorcycle magazines to out the rides, and he didn’t hang the bikes in the parking lot at lunch

Oddly, it wasn’t until he an emergency medical technician he even thought to swing a leg a motorcycle. “As a paramedic, I couldn’t why anyone would want to a bike,” Ron explains. “It just make any sense. If a dog ran out in front of you’d go down. In 1980, I a bike of my own to find out what the was.”

Hook, line and Ron bit hard, and quickly grasped the of two-wheeled power. He kept his bike, a 1974 Yamaha just a few short months buying a friend’s Honda because it had saddlebags. Ron did some and the CX kept him occupied until he the Gold Wing.

He joined a Gold Wing group, and some of his fellow riders choosing second motorcycles.

were gravitating toward Fat Boys, but Ron thought those common bikes — why not look for unusual? This was around the Ron and some motorcycling friends to Europe, in September 2001, after the airports reopened 9/11. They rented and rode from Switzerland to to attend the Milan Motorcycle

Running into the rotary: the W-2000

During that Ron also visited the Deutsches in Munich, where he saw a Hercules rotary-powered motorcycle. It was love at sight. “The Hercules was so from anything I’d ever before,” Ron says. “If I was going to get a bike, I wanted something

Back home, Ron tried to information about the Hercules hoping to find one for sale. He up empty-handed. Instead, he bought a Honda CBX, but he didn’t there and added a Honda Turbo to his stable. On a CX500 forum, a post about a RE-5 piqued his interest — he realized the Japanese maker had a rotary-powered motorcycle.

His fascination rotary power still Ron began researching the RE-5, and bought a 1975 model because of its unusual engine.

when he met Jess Stockwell, a enthusiast and protégé of the late Sam who was considered THE authority on rotary A former Sachs employee, Sam and serviced Hercules W-2000s they were new through Recycle U.S.A. in Ohio, in business for 40 years before the shop to Jess in 2009. In 2008, Ron visited Jess in Tenn. with his RE-5, and the tuned Ron’s Suzuki.

visiting Jess, Ron was allowed to a 1976 Hercules W-2000 once belonged to Sam.

Not any Hercules, Sam’s Hercules was specially prepared and purportedly had displayed at Sachs’ North headquarters. In a deal with a executive, Sam purchased the W-2000 for his collection, keeping it many before selling it to Jess. Jess was raising capital to buy Recycle, he sold Sam’s to Ron.

A rare Hercules

The W-2000 is referred to as the first Wankel rotary-powered motorcycle. in 1919 by German engineer Wankel, the rotary power was thought by many to be an ideal The Wankel rotary had far fewer parts than a four-… and was theoretically more efficient.

But it wasn’t until 1957 Wankel, working with built his first running rotary engine. The transportation took notice of this new from aircraft manufacturers to to motorcycle builders, everyone interested in the new technology. One of the first to the Wankel technology was Germany’s Sachs, at that time largest producer of two-…

In the 1950s, German motorcycle Hercules used Sachs two-… engines to power many different motorcycles, and scooters. Sachs purchased in 1963, and eventually merged the Zweirad Union, which the DKW brand.

Hercules developed the using the Sachs rotary in the late 1960s, and a prototype was first shown at the 1970 Cologne Fall Motorcycle Reaction was mixed: “Should it be as a great breakthrough, or a temporary diversion?” mused Dan Hunt in his paragraph about the prototype rotary in the January 1971 of Cycle World .

According to the 20,000 of the 294cc Sachs engines found in the prototype had already been used in snowmobiles, and another version of the was used for powering small In the prototype, Hercules borrowed a gearbox and shaft drive a BMW R27 single.

How the rotary-powered motorcycle

When Hercules officially the W-2000 in 1974 (sold as a DKW in the because a bicycle manufacturer had rights to the Hercules name), the BMW had been replaced with a unit with chain drive sourced from a 400 dirt bike. A set of bevel transferred power from the shaft through 90-degrees to the mainshaft, and the clutch was a seven-disc running in an oil bath.

Of course, is of primary interest is the Sachs engine, which used a spark plug firing a rotor with apex

As explained in the May/June 2011 of Motorcycle Classics in an article Suzuki’s RE-5 rotary-powered (effectively identical in principle): rotor’s tips seal the housing to form combustion Instead of a crankshaft, a rotary an eccentric shaft with the riding on the eccentric. A stationary on the end of the eccentric shaft keys the to the eccentric shaft.

Combustion pushes the rotor away the combustion face, causing the shaft to rotate. The shaft’s defines the throw of the rotor the stationary gear defines the position on its axis. As the rotor its axis shifts, causing the to orbit and alter the combustion for intake, compression, ignition and phases.”

When first the Sachs engine was rated at 23 a figure that was later to 32 horsepower. While listed at for comparison to a piston engine figure, in theory, should be by two for a 588cc capacity: A single-rotor produces one power … crank revolution, whereas a 4-… requires two crankshaft for each power ….

The running consists of a tubular steel with twin front that bend back and run the top of the engine. As a result, the Sachs appears to hang from the although it’s also at the rear.

The Hercules wears wheels at both the front and and the front brake is an 11.8-inch while the rear is a 7-inch

Period tests of the Hercules the machine credit for its cornering but fault the 6.5-inch ground as a major detractor in its cornering

Cycle World said the would burble along at an 60mph, and would climb a in sixth gear at 50 to 55mph, but it took at least one and most two downshifts to overtake a car on the highway: is not spectacular, just adequate if the of the car you’re passing doesn’t on it at the same time. If he does, you Cycle World said.

distribution of the Hercules W-2000

Ron that while the W-2000 well have been the rotary-powered motorcycle offered through a dealer network, he it was built solely to test acceptance of a rotary-powered two-wheeler. His indicates the first container of 40 W-2000s — 34 with red tanks and 6 yellow — arrived in the U.S. in 1975 and was delivered to Rotary U.S.A.

The Rotary sales visited dealers across the espousing the virtues of the Wankel. New were enlisted, and rising for the $1,900 rotary showed was some interest.

In May 1975, introduced the KC-30 GS Enduro dirt bike, and shipped two to Recycle. Although it generated excitement, the KC-30’s $2,900 tag … any sales of the model. And by the end of sales of the Hercules W-2000 had to a trickle, perhaps because had announced an oil-injected model was for 1976.

Early machines required the oil and gasoline.

The W-2000 Ron owns is one of 199 oil-injected 1976 machines Of those 199, it is unknown how landed in the U.S. Unlike the RE-5, there is no crankcase oil in the W-2000 engine, and it does not run oil.

Instead, Ron runs 20/50 in the injector tank. W-2000 is finished in Midnight although Danube Blue was an for 1976. Presumably because it was at Sachs’ head office, Hercules features a factory-polished fan and transmission.

After purchasing the from Jess — with than 6,000 miles on the — Ron changed the front brake and added a rare factory right-hand mirror. That’s all done since buying it. The had been changed while in care, and Ron has carefully added more than 300 miles to the

Because he owns a Suzuki and the Hercules W-2000, Ron can speak some authority about mid-1970s rotary-powered motorcycles. Japanese went one way, and the went the other,” he says. RE-5 has five different for four different fluids, the oil and the points are all running off of something and the carburetor is a bit complicated. The Hercules, by is very simple, with a fan in the and the ignition runs off the same

Ron says that running, the sounds like a cross a two-… and a four-…. On the road, torque is a bit lacking, but with the gearbox he can keep the W-2000 along on the highway. For him, the is part of the charm, and he will to put miles on the Hercules W-2000, if a bit slowly.

Just 1,784 of the Hercules motorcycles were and Ron says the plug was pulled not they weren’t well but because they missed set monthly sales quota by 25 “It was just too weird, I guess,” Ron of the W-2000. “But that’s attracts me to these orphan — they might be weird, but also different.” Which things full circle, because that’s the same way Ron approached motorcycling — differently.
