Tempo's, Munga's and Haflinger's

In the US and Britain two stoke engines have always been seen as something of a second rate engine, suitable only for power tools, snowmobiles and small motorbikes. The Germans and other Europeans however were never so reticent about two strokes and for a time they were used by dozens of companies to power everything from motorcycles, cars, trucks and aeroplanes. This article explores three unorthodox European military vehicles with interesting design features.  

Tempo G 1200

Oskar Vidal & Sohn founded Tempo Werkes of Hamburg in 1924 building motorised triporters. These little 3 wheeled delivery vehicles proved to be extremely popular and the foundation of the company's success.
By the early 30s Tempo were building three wheeled delivery trucks popularly known as the Tempo Hanseat. Hanseats were powered by a proprietory JLO two cylinder two stoke motors in either 200 or 400cc capacity. Versions of the Hanseat remained in production until 1956 and were widely exported around Europe.

Oscar Vidal shows off a Hanseat woodie. The three wheeled Hanseat's were incredibly popular vehicles. Under German law they could be driven without a license and, thanks to the small size of their engines, they were exempt of road taxes. They were capable of hauling loads that belied their tiny engine capacity. Companies such as Phaenomen, Framo and Carl Borgward's Goliath also built similar machines.

In 1936 Tempo-werke responded to a Landwehr (army) contract for a four wheel drive light utility vehicle and their response was uniquely unorthodox. The G1200 was powered by two 600cc JLO two-stroke motors, one in the front and one in the rear. Each engine separately drove the front and rear independently suspended axles in much the same arrangement as Tatra used in their trucks. Each engine had its own gearbox and could be operated together for full four wheel drive or they could be run independently for either front wheel or rear wheel drive operation. The car had high ground clearance and with the body floating over its independent suspension it was able to comfortably traverse even the roughest ground. Top speed was 70 kilometres per hour. Fuel economy was a reasonable 12 litres per hundred kilometres, which could be reduced further by running on one engine alone.
Few German Tempo G1200s survived the war but several Scandinavian and Eastern European examples survived. This example is in the German Sinshiem Technik museum. It has been posed in a position that highlights its ability to handle rough terrain. 

Despite this the Landwehr were prejudiced against two-stroke engines in both cars and motorcycles, even refusing Germany's biggest motorcycle manufacturer DKW a contract, so it came as little surprise that they showed no interest in Tempo's offering. Tempo however were not disheartened and successfully shopped the G1200 to other European armies, including Denmark, Sweden, Finland, Latvia, Croatia, Czechoslovakia & Romania. The G1200 was even sold as far afield as Mexico, Brazil and Argentina.

The Second World War put an end to Tempo's export market. The German army took over those Tempo's on the production line and seized some of those in foreign service. Production ceased in 1943 after only 1335 were built. After the war a single engined civilian version was released for a short time, but it was Tempo's three wheeled product which revived the company's fortunes. The three wheeled Hanseat continued in production until 1956 when it was replaced with a modern, four wheeled van (see photo at the top). Tempo was later bought out by the truck company Hanomag.

DKW Munga

In 1956 the Bundeswehr tendered for a replacement for the army's aging Willy's Jeeps. DKW's offering was a four wheel drive vehicle powered by their trusty 3=6 900cc two stroke engine, but with lower gearing ratios. Sales were originally restricted to the army and government agencies, such as the fire department. The Munga (which basically means multi-purpose, all terrain vehicle) was also purchased by the armed forces of other NATO countries. In late 1957 DKW released a civilian version which proved very popular with farm, forestry and alpine rescue services all across Europe. Mungas were also exported to South Africa, Argentina and Brazil. All told about 47,000 were built before production ceased in 1968.

Steyr-Puch Haflinger

In 1957 Erich Ledwinka, son of Tatra's legendary chief designer, Hans Ledwinka, left Tatra and retired from Czechoslovakia to Austria. Erich seemed unable to avoid following in his father's footsteps and took a job at Steyr-Puch. One of his first projects was for a light four-wheel drive. The result was very much a little Tatra, based around Tatra's distinctive backbone chassis with independently suspended half axles and powered by a rear mounted 640cc twin cylinder boxer four-stroke engine. The Haflinger was simplicity and robustness combined. The body was a basic steel tray without any creature comforts and could be easily and quickly be removed from the chassis. All surplus equipment, such as doors, roof, and bench seats were optional. In its simplest form it was only 600kgs and could be lifted by four men.
The first Haflingers went on sale in 1959 and both the Austrian and Swiss army bought then to replace their aging fleet of Willy's Jeeps. They were also sold as far afield as South Africa and Australia. The Australian army bought some and used them successfully in Vietnam. All up about 16,500 Haflingers were built between 1959 and 1975. Later models had optional fibreglass cabins, proper doors and detachable hard roofs. In 1968 Steyr-Puch released a much bigger version, the Pinzgauer, a large 4x4 or 6x6 truck. The Pinzgauer however was powered by a much larger four stroke engine. It remains in production today.

Blue Haze Ride 2011


The Japanese Bike Show organised a ride for two-stroke bikes on Saturday 26 November 2011. The Blue Haze Ride started at Burswood Casino carpark at 9am before heading off to the E-Shed Markets Fremantle, where the bikes were displayed as part of the Fremantle Festival.


The Ariel on arrival - for once I was mostly on time! A photo by Graelin.



Although organised by the Japanese Bike Show it was open to all two-strokes regardless of origin. It was great to see some 'oddities' out there. This is a 1972 Jawa Californian from Czechoslovakia. Jawa built the Californian with the export market in mind to bring in much needed hard currency.

A Kawasaki 750 triple and a range of modern two-strokes.

1970s Yamaha and Suzuki.

A trio of Yamaha's. Yamaha's two-stroke range started in 1955 with the YA-1, a copy of DKW's pre-war RT125 motorcycle - the most copied motorcycle in the world. http://heinkelscooter.blogspot.com/2010/04/das-kleine-wunder-story-of-remarkable.html



Very modern two-stroke sports bikes, including an Aprilla.

I'm not a great fan of modern bikes but I must admit this 1985 Suzuki is pretty damned stylish. If I had to.....

A BMW R80/7. Well, not really a two-stoke, so that probably explains why it was parked in a corner.

The group sets off. A photo by Graelin.

The main pack arrives at the E-Shed. Typically I lost my way on the ride (too slow, wrong freeway exit) so I arrived slightly before the main group, which allowed me to snap a couple of pics as they drove. The scream of the two-stroke engines was quite wonderful.

The pack settles in







As I'd arrived slightly earlier than most I parked in the E-Shed motorcycle bays. Why is there always so little motorcycle parking in Perth? The E-Shed is a popular coffee stop for motorcyclists on a Fremantle run but there are only about 10 bays (quite a lot really) awkwardly spaced around a large transformer box. I'm guessing that if the transformer box wasn't there there would actually be NO motorcycle parking there at all.

Some bikes were trailered in specially. Ray and Anne bought down their collection of British lightweight two-strokes.

Ray poses with his collection.

A 1952 BSA Bantam D-1, a 1954 James Cadet and a 1954 Francis-Barnett.

Probably the most successful British motorcycle of all time. Other British motorcycles may be more famous, more powerful, and more expensive, but the Bantam was THE bike almost everyone of a certain age first learned to ride on. The Bantam of course was the British version of the German DKW RT125.

I moved the Ariel around to join its English brethren.

The English contingent certainly drew a crowd. I was quite surprised by the number of English gents who suddenly appeared with that nostalgic look in their eye saying, "I first learned to ride on a Bantam when I was 14..." There were dozens of them and it was great to hear all their stories. I had a good chat with a fellow who did his mechanic's apprenticeship at BSA in Birmingham. He had lived half way between the BSA factory and the Francis-Barnett/James factory but went with BSA as he had more opportunity to learn from them as BSA at least built their own engines. F-B and James used Villiers engines. He'd owned a Bantam, a Gold Star (which he didn't like) and a Leader at various times.

An immaculately restored 1974 Kawasaki 750. It was for sale for $19K.

Chris' 1986 MZ ETZ250 was a latecomer to the show but it certainly drew a bit of attention. Two English guys instantly recognised it and came over for a chat. The East German eisen-schwein (iron-pig) was built at the old DKW works at Zchopau by MZ (Motorradwerke Zchopau) and exported all over the Eastern Bloc and - surprisingly - the UK. In the UK they were dirt cheap and almost became the BSA Bantam of a later generation. MZs certainly weren't flashy bikes but they could tolerate abuse and neglect and just keep going.

Another Czech Jawa. This one is roughly 1968-70. It's been restored with a mix of parts. Still looks beautiful though. The similarity with a DKW is obvious.

Looking over the crowd at about 12pm. I think it was a good turn out and there was a lot of interest from passersby's. There was good chat and discussion amongst all the riders, regardless of what they were riding. Good work Mike and the team for arranging the ride. http://www.japbikeshow.com.au/intro.htm It was a great day!

At about 1pm the crowd began to move off. Ben hops on his beautifully restored 1970 Jawa.

Now I tend to think of this as an 'old bike' problem, but no. One of the riders gets a helping hand with a push start. We shouldn't laugh as it's happened to all of us. As it turned out I was almost the last bike away. When I moved the bike to join the English contingent I forgot to turn off the petrol tap and the engine was flooded (note to self - DON'T FORGET TO TURN OFF THE PETROL TAP - AGAIN!). It needed a good half an hour to rest before it kicked over again. Thanks to Simon from Perth Street Bikes for helping try to start it with me.

The Endeavour replica was in port too so I popped over to have a look. I was only stopping for a minute to have look but another two groups of English tourists came over to ask, "Isn't that an Ariel?" Happy days!

Planes of Fame Museum


Planes of Fame Air Museum was founded by Mr Ed Maloney in Claremont, California in 1957. From an original collection of only 10 aircraft, the collection now comprises over 150 across two locations in Chino, California and Grand Canyon, Arizona. The museum aims to keep these vintage aircraft in the air and have many restoration projects underway. We visited the Arizona museum on our way to the Grand Canyon. There weren't many visitors so I had the chance to talk a little with the volunteers manning the counter - but not for too long as while Shelly likes auto museums she doesn't find aircraft museums quite as interesting.

The museum has a great and informative website too - http://www.planesoffame.org/

This magnificentLockhead Constellation airliner graces the front gate of the museum. This aircraft was the personal transport for General Douglas MacArthur during this time in Japan and the Korean war. http://www.planesoffame.org/index.php?mact=staircraft,cntnt01,default,0&cntnt01what=stplanes&cntnt01alias=VC-121A&cntnt01returnid=128

A Convair CV240 airliner. This plane is in flying condition.

View of the collection from the hanger doors. The Grand Canyon museum is smaller than the Chino museum, which holds the main collection, including a Boeing B-17 Flying Fortress and B-29 Superfortress.

A replica of the World War I Nieuport 17 fighter flown by the American fighter ace, Billy Walker. Walker was one of a number of Americans who enlisted in the French flying corps at the outset of the war. Their squadron became known as the Lafayette Squadron, after a French general who served with Washington during the War of Independence.

A World War I Bristol F2B. The British Bristol fighters were sold to the US and many Allied nations in the aftermath of the war.


A World War I Siemens-Schuckert D.IV fighter from Germany. This non-flying example is a really rare survivor. The Treaty of Versailles banned Germany from possessing an airforce and all German aircraft were commandeered for war reparations or destroyed.



A Grumman G-32-A Flying Barrel.


A Stinson Reliant executive plane. Very sweet




A Stinson Sentinel air ambulance. These planes were used as transports, spotters and air ambulances during the Second World War and Korean Wars. My great uncle John owned one of these until recently. He had found it as a wreck at an Indian airfield during an epic round the world flight in the 1980s. He later purchased the plane and a wrecked Tiger Moth, had them shipped back to Australia and restored. I'll write something about that later.

A Messerschmitt Me-109G



It looks like a Japanese World War Two Aichi Val dive bomber but is in fact an American Vultee BT-15 converted to look a Val for the movies. The museum has an actual Val under restoration.

Douglas Skyraider. These aircraft were build too late for the WWII but saw extensive action in Korea and Vietnam.

North American Trojan T-28B

Douglas Invader bomber. Built towards the end of the Second World War, they saw service in Korea with the US Airforce and also in a number of foreign airforces.

A Ford.. and a bomb!

The museum strongly believes in keeping these machines flying. Many of these vintage planes have been picked up by retiring US airforce personnel in order to keep their flying dreams alive in retirement. Many however find that the expense of keeping the planes running difficult to sustain and, as with vintage cars and bikes, they can be a lot less fun to fly that they would appear. The Stinson Sentinel for instance was a rushed design during wartime and it has some poor handling characteristics that prevented it from enjoying a post war career. Generally, unless there is a special connection, the owners' children aren't keen to take on the responsibility and cost of maintenance so planes are handed over to the museum who display them and keep them flying.

There was also an extensive of aircraft models. This is a Northrop YB-35 Flying Wing. Northrop experimented extensively with flying wing designs. A prototype and pre-production versions of these four engined bombers were built after the end of the war but were too unorthodox for the Airforce. A jet version - the YB-49 - was also built but all were eventually scrapped. The two engined 1941 prototype is the only surviving example of this amazing machine. It has been restored to flying condition at the Chino air museum.

Outside the hanger are a collection of 1950s jet fighters. Being exposed to the elements, these planes look a little worse for wear.

From left to right, a Russian Mig-17, a British De Havilland Vampire and a French Aero Delfin L29.

Republic Thunderjet F-84B

A US Lockheed Shooting Star T-33A. These fighters went up against Russian Mig-15s & 17s during the Korean War.

The ubiquitous Russian jet fighter of the early Cold War era - the Mig-17. They were a popular jet fighter and sold all across the Soviet Bloc and Middle East.

The twin boom De Havilland Vampire was Britain's first operational jet fighter. The Vampire flew before the Gloster Meteor but due to engine problems did not reach front line units until after the Meteor was deployed in the last months of the Second World War.

Surprising as it sounds the Vampire is largely constructed of wood. The wings and booms are steel skinned but the rest of the body is composed of marine plywood. The weather has certainly taken its toll on this plane and the wood paneling is badly flaking.

An aircraft fuselage awaits its turn for restoration.

This interesting flying wing was a home built aircraft based on the designs of the German Horten brothers. The Horten's worked originally with tailless gliders before moving into powered aircraft. Their aircraft were always constructed of classic lightweight materials, such as doped canvas and plywood. The builder of this aircraft constructed his of fibreglass, a much weightier material. When completed the aircraft proved too heavy to get itself airborne. It was eventually donated to museum and is awaiting its turn for restoration.

A line of engines lying in the dust. I don't know what aircraft these come from.
