Motorcycle trailer
A motorcycle trailer is a trailer that is pulled by a motorcycle .
In Germany, “trailers behind motorcycles” are subject to special registration, insurance and traffic regulations that differ from those for car trailers. These trailers are available in many different designs. Very few motorcycles are retrofitted with a trailer coupling and the number of motorcycle trailers is very small compared to car trailers.
History and background
Beginnings

Even in the early days of motorization around 1900, motorcycles were also used as tractors in order to expand the limited transport capacities of two-wheelers with a trailer or trailer. In 1896, Jean Trancle-Armand received a patent in the USA for a connecting joint between motorcycle and trailer. During this pioneering period, the trailer competed with the sidecar , which became the more practical solution in the field of passenger transport.
During the Second World War , trailers with a total weight of up to 350 kg were used behind the Wehrmacht vehicles from 1941 onwards . The heavy Zündapp KS 750 and BMW R 75 had the so-called standard bulky hook, a pin coupling, so that these all-terrain machines could pull light trailers or artillery.
In the GDR since 1957 the right trailer for the Berlin, Troll and Wiesel scooters was offered with the Campi for 420 marks. In West Germany there were similar models under the names Campingboy and Camping-chen von Baudisch, Camping Rolly (Schumacher & Co), Flott (Calberlah), Campo (MWF), Trip (Faho) and Elan (Vögtle & Zeller). The Czech manufacturer Jawa offered additional luggage space with the single-track trailers of the type PAV-40 and PAV-41 in the 1960s, which made camping and vacation trips for two possible even with smaller motorbikes or scooters . For many people who could not afford a car, a motorcycle was the everyday vehicle at that time.
present
In Asia, where bicycles and small motorcycles are very important means of transport, trailers for transporting goods and people are widespread. In Europe and America, where the motorcycle is primarily a recreational and vacation vehicle, trailers enable motorcyclists to take more luggage with them when traveling . Manufacturers such as Schuring, EZS or Watsonian not only offer trailers - preferably for heavy motorcycles like the Honda Gold Wing and Pan European - but also the necessary trailer hitches.
In the United States , manufacturers like Tailwind and Bushtec build motorcycle trailers; Small folding caravans (pop-up campers) for one or two people are available from various providers. There is also a long history of building teardrop trailers that are pulled by smaller cars and motorcycles.
In Germany , motorcycle trailers only play a minor role in road traffic. According to Andreas Schmidt, currently the only German manufacturer, one of the main reasons for the low prevalence of motorcycle trailers in Germany is the speed limit. These individual, one-off productions of trailers are not only used to transport luggage, but also, for example, as an advertising medium .
The German Road Traffic Licensing Regulations describe the dimensions and weights of trailers. Trailers with an operating license behind a motorcycle can be driven as a license-free and insurance-free trailer with a repeat license plate.

technical structure
Motorcycle trailers are connected to the towing vehicle with a detachable trailer coupling and have an axle with one or two wheels. Usually the structure is attached to a frame, but self-supporting shell structures ( monocoques ) are also possible. Various designs such as platforms or boxes for transporting loads are offered. Hydraulic shock absorbers are not mandatory, but can improve driving stability. The dead weight of a single-track trailer is usually less than 40 kg, for single-axle trailers it is usually over 55 kg, the permissible total weight is between 80 and 300 kg.
Single track trailer
Motorcycle trailers can be built as single-track trailers with only one wheel. These lean into the curve with the motorcycle. A special trailer coupling with a universal joint is required for this, which only allows up and down movement on uneven road surfaces and a bend perpendicular to the longitudinal axis when cornering and always keeps the trailer in the same inclined position as the two-wheeler . This design is only found on light trailers, as depending on the position of the trailer wheel, up to half of the total weight is placed on the rear of the motorcycle. In a single-track trailer, the suspension is usually implemented as a one or two-armed swing arm with a strut, as is known from the rear wheel of a motorcycle. The wheels are mainly scooter or motorcycle wheels.
Single axle trailer
If the motorcycle trailer is built conventionally with one axle and two wheels, a ball coupling behind the rear wheel offers the simplest connection so that the trailer remains horizontal when the towing vehicle leans into a curve. As a special form, a semi-trailer with a 50 mm coupling ball instead of a passenger seat behind the driver of the motorcycle was approved in Germany. The wheels are mostly eight- or ten-inch standard wheels, like those on small car trailers. In the USA and Canada, two-wheeled trailers are usually equipped with very long drawbars, rigid axles and leaf springs , in Europe usually with rubber spring axles . In the USA, Tailwind offers its patented, spring-loaded and damped Duoflex drawbar, which compensates for the trailer's pitching movements, so that the effects on the towing vehicle are reduced. According to the law in Germany, a double-axle trailer is considered to be single-axle if the distance between the axles is less than 100 cm.
Designs
Box trailer
Cargo trailers with an open box structure or a box structure that can be closed with a lid made of fiberglass-reinforced plastic , aluminum or sheet steel are the most common structures and are used in Europe and America to transport luggage or pets.
Platform trailer
Open platform trailers for transporting boxes or bulky goods are indispensable in large parts of Asia as a means of transport in the everyday life of small businesses and are also offered with a wheel in Europe.
Folding caravan
Small folding caravans such as the Mini Mate or the Kompact Kamp, which in addition to the luggage transport in the trailer locker above, offer a folding tent and mattresses for one or two people, are sold by many suppliers in the USA and Canada. In Germany, however, larger folding tent caravans such as the Rhön Universal or Klappfix are also pulled behind teams .
Caravan
Closed caravans such as the 140 kg Calypso and the mini Airstream trailer with a width of one meter, especially for use behind motorbikes with berths for one or two people, are occasionally built in Europe by experienced inventors and given an operating permit by the TÜV. The Swedish Goldbrand caravan is even 125 cm wide.
Teardrop pendant
Lightweight teardrop trailers made of plywood or aluminum for pulling behind small cars or motorcycles have been a tradition in the USA since the 1930s and are manufactured by small series manufacturers or according to construction plans in amateur construction. These small sleeping cars (from 1.3 m × 2.6 m floor space) offer more generous lying areas and tipping safety due to the lack of width restrictions and external wheels. They are usually equipped with an outside kitchen under the tailgate of the trailer.
Coupling systems
Ball coupling
The standardized 50 mm ball head coupling with E-approved coupling ball is widespread in Europe. In the US, ball heads with a diameter of 1 ¼ "or 1 ⅞" are common, which do not fit European drawbars. Ball couplings allow a rotary movement of more than 50 degrees to both sides. For the Honda Goldwing, there are also hidden towbars installed under the case system, where only the detachable coupling ball is visible.
Universal joint coupling
Jawa connected its single-wheel PAV trailer with a universal joint to the tractor and the GDR scooter trailer Campi used the same technology. The German manufacturer moppedänger further developed this coupling in order to be able to separate the unicycle trailer from the motorcycle more easily and also to connect heavy trailers safely and lockable to the tractor.
Pin coupling
In the United States, as an alternative to the ball, pin couplings are occasionally used, in which a ring on the drawbar side is hung on a vertical pin at the rear of the motorcycle and fixed with a safety device on top of the pin. Rotatable drawbars are absolutely necessary for this, but they can also be used in combination with ball couplings to prevent damage to the pulling device in the event of a fall or if the motorcycle falls over.
Electrical connection and lighting
In Europe, like in cars, standardized 7-pin or 13-pin trailer sockets are installed, in America there are a large number of non-standardized connection plugs. Two rear lights, two brake lights, two red triangular reflectors and license plate lighting are required in German-speaking countries, direction indicators are only required if the trailer covers the turn signals of the towing vehicle. For side identification, at least one yellow, non-triangular reflector is required on both sides .
Brake systems on the trailer
As a rule, trailers behind motorcycles do not have their own brakes because of their low weight. The overrun brake is very rare in Europe because it increases the dead weight of the trailer and has to be checked. On the other hand, you can have a higher towing load approved for a towing motorcycle for braked trailers in individual cases (in Germany: assessment by a technical inspection agency or certificate from an officially recognized monitoring organization). In the USA there are electrically operated trailer brakes that are activated via control units with inertia sensors or the contact of the brake light switch.
Legal basis in Germany
Towbars on motorcycles
In Germany, a motorcycle must have a towing device approved by TÜV or DEKRA and entered in the vehicle documents at the registration office in order to be allowed to tow a trailer. Contrary to the information provided by some motor vehicle test centers, a clearance certificate from the motorcycle manufacturer is not necessary and will not be issued by him.
The test center can test the trailer coupling in accordance with a TP report according to § 22 a StVZO and § 13 of the Vehicle Registration Ordinance (FZV) and carry out the attachment acceptance on the motorcycle according to § 21 and § 19 StVZO.
The Road Traffic Licensing Regulations limit the trailer load for unbraked trailers to the empty weight of the motorcycle plus 75 kg for the driver divided by two. This means that, for example, a heavy touring motorcycle with an unladen weight of 325 kg can tow a trailer with a maximum total mass of 200 kg. The test center can approve a higher trailer load for braked trailers.
Approval or operating permit for motorcycle trailers
In Germany, motorcycles are allowed to tow both approved trailers and motorcycle trailers that are not subject to approval and which can be driven with an unstamped subsequent number plate with the same number combination as one of the owner's towing vehicles. These motorcycle trailers do not require registration or insurance, but must be checked by a vehicle inspection center in accordance with Section 13 EG-FGV, receive a vehicle identification number from the vehicle inspection center in advance and, upon acceptance, an operating license . They are not subject to the two-year general inspection requirement. This operating permit must be stamped by the vehicle registration office. In order to go through the procedure successfully, it is advisable to check the feasibility with the technical test center and the licensing center beforehand, as many departments do not know this special form and the legal basis.
The width of a motorcycle trailer must not exceed 100 cm, the general restrictions for vehicles of all kinds apply to the maximum length and height. Motorbike trailers that are free of registration and insurance must not be pulled by cars.
Driving license law
For driving trailers behind motorcycles no additional license is needed, it is enough of a motorcycle license .
60 km / h regulation in Germany
In Germany, the general speed limit of 60 km / h applies to motorcycles with trailers outside built-up areas, on motorways and motorways, stipulated by § 3 and § 18 StVO, which can pose a significant risk to the following motor vehicles, especially on the motorway. Petitions to lift this speed limit in Germany have been initiated several times, most recently in January 2014:
“A minimum speed of 60 km / h is required on German autobahns, so that a motorcycle with a trailer can hardly be moved legally there. An increase in the general speed limit to 80 km / h [...] would finally remove these nonsensical traffic obstacles on German motorways. […] Here in Germany there is an additional risk of being harassed by truck drivers who have to switch to the fast lane every time such a traffic obstacle appears in front of them. "
In the reason for the rejection, the Petitions Committee refers to the opinion of the motorcycle manufacturers obtained by the Bundestag, from whose point of view there is no need to lift this speed limit and that the vehicles they produce are fundamentally unsuitable for operation with trailers. At the request of the Federal Ministry of Transport, the Motorcycle Industry Association (IVM) had no knowledge of the driving dynamics of trailer combinations, and from the perspective of the IVM there was also no market for motorcycle trailers in Germany.
Motorbike combinations with trailers
In Germany, the legal provisions for motorcycle combinations with trailers essentially correspond to those for motorcycles with trailers. Due to the increased curb weight, a motorcycle combination can pull a trailer with greater mass.
For German trailer drivers with a trailer coupling installed in the middle between the motorcycle and the sidecar, there is the option of obtaining an exemption from the regional council in accordance with Section 70 StVZO. After a positive assessment by a vehicle inspection body, an exception from § 32 StVZO can be approved in individual cases and a trailer width greater than one meter can be entered for the motorcycle combination.
Legal basis in Austria
In Austria, according to Section 104 of the Motor Vehicle Act (KFG), motorcycles may only tow light trailers of class O1 that are approved for traffic . These trailers must not be wider than the motorcycle and they must be connected to the towing vehicle with a secure tow bar. As in Germany, twice the total weight of the trailer must not exceed the unladen weight of the motorcycle, which has increased by 75 kg.
If the width of the trailer does not exceed 80 cm, it only needs to be equipped with one of the lights otherwise prescribed for trailers. The triangular reflector must be separated from the light emitting surfaces of the luminaires and attached in such a way that one point of the equilateral triangle points upwards. This reflector must be permanently connected to the vehicle.
When pulling a light trailer, the speed of 100 km / h must not be exceeded.
Legal basis in Switzerland
The maximum speed for motorcycles with a trailer is 80 km / h. A separate motorway vignette is not required for rigid trailers (usually unicycle trailers), trailers and sidecars of motorcycles in accordance with Directive 15-01 National Road Tax.
Legal situation in other countries
Speed limits in km / h for motorcycles with trailers in other countries on country roads and in brackets on motorways (as of November 2018):
- 70 (70): Lithuania
- 70 (80): Albania, Poland, Turkey, Hungary
- 70 (90): Spain, Estonia, Luxembourg, Romania, Russia, Belarus
- 70 (96): Great Britain: Trailers are only permitted for motorcycles over 125 cc. The trailer may be a maximum of one meter wide, the length (measured from the rear axle of the motorcycle) may be 2.50 meters and the total weight may not exceed 150 kg or 2/3 of the fully fueled vehicle weight.
- 70 (120): Portugal
- 80 (80): Bosnia-Herzegovina, Denmark, Finland, Greece, Norway, Poland, Sweden, Czech Republic, Croatia, Latvia, Liechtenstein, Malta, Macedonia, Montenegro, Norway, Slovenia, Ukraine
- 80 (90): Netherlands
- 80 (100): Bulgaria, Ireland, Serbia, Cyprus
- 80 (130): France
- 88 to 120: USA: The speed limits correspond to those for cars with trailers; the rules vary from state to state.
- 90 (90): New Zealand, Slovakia
- 90 (120): Belgium
In Italy, motorcycles registered there are not allowed to pull trailers. This was confirmed by a judgment of the European Court of Justice on February 10, 2009. According to the Vienna Convention on Road Traffic of 1968, EU states have the right to refuse to allow trailers behind motorcycles. The Italian Republic ... however makes it clear ... that motorcycles registered in other Member States are permitted to carry a trailer on Italian territory, since they are in international traffic within the meaning of the aforementioned Convention.
Meeting and scene
In Germany, the only known motorcycle trailer meeting has been held in Schotten , Hesse, every year since 2005 on the first weekend in June . Due to the closure of the Falltorhaus motorcycle meeting point, the 2019 meeting will take place for the first time in the Caravan Park in the neighboring town of Laubach .
At the largest sidecar meeting in Europe, the EGT with over 1000 participants, motorcycle trailers can be found in large numbers every year. There is a lively exchange of experiences, especially about the handling of the legal framework by the various licensing authorities.
In Germany, trailers are often pulled behind Honda Gold Wings . In the German Goldwing forum, the drivers write about their experiences.
The combinations of the Russian manufacturer URAL sold in the USA and Europe have been approved for use with trailers in Germany since 2010.
The American and Canadian motorcyclists with cargo trailers and folding caravans exchange their experiences in a special trailer forum on motocampers.com, and the American Honda ST forum has its own trailer department with many reports.

Remarks
-
↑ In the driving-regulation is no regulation for trailers ( "E") is present behind the driver's license class A. Some authors conclude from this that the "non-regulation" implies a ban on trailers behind motorcycles. Beck's short commentary on road traffic law in the new edition shares this view :
