Victoria V 35 Bergmeister
The Victoria V 35 Bergmeister is a motorcycle made by Victoria-Werke AG in Nuremberg . It appeared in late 1953 and was built until early 1955; after that, individual pieces were created from parts stocks. The total production number amounts to approx. 5000 machines.

The Victoria Bergmeister is essentially a design by Richard Küchen , who was particularly known as an engine builder. It is characterized by the smooth housings of its motors and chain gears: both design features that are also implemented in the Victoria Bergmeister.
Two-cylinder V-engine
The Bergmeister engine is an air-cooled two-cylinder four-stroke engine that has a capacity of 347 cm³ and develops 21 hp (15 kW). It is a V-engine with a 64 ° cylinder bank angle , whose connecting rods run next to each other on a common crank pin ; this makes the engine relatively short. The cylinders are less endangered than those of a boxer engine when cornering sharply or in the event of a fall . The camshaft, driven by a chain, is located above the crankshaft and controls the valves via roller tappets , push rods and rocker arms . Because of the relatively high position of the camshaft, the push rods are short.
The electrics and carburetor are located under smooth covers, which protect the alternator and ignition distributor from dirt and moisture. However, this hinders heat dissipation, so the alternator often failed when driving at night. Retrofitted ventilation was often seen in sports use. To carry out adjustments, the front cover is lifted upwards, for which purpose a single screw must be loosened at the bottom. The carburetor cover, which consists of two shells, can be removed just as easily. A disadvantage of the elegant placement of the carburetor is the long intake paths (competing machines were therefore partly equipped with two carburetors).
To adjust the ignition, there is a viewing hole on the left in the engine housing, usually covered with a screw, through which the markings for the correct ignition point can be seen. The arrangement of the spark plugs on the inside of the cylinder heads is less maintenance-friendly. A light is fitted under the tank as standard to make repairs at night easier.
Chain transmission and cardan drive
The Bergmeister gearbox forms a single unit with the engine. Because the crankshaft is in the direction of travel, the gearbox is arranged behind the crankshaft and clutch without a special primary drive, and the rear-wheel drive with cardan shaft does not require any power diversion. The four-speed gearbox is designed as a chain gear , it has foot shift and an additional auxiliary manual shift lever on the left side of the vehicle.
Victoria supplied various gear ratios for the Bergmeister's final drive, i.e. interchangeable gears, depending on whether the motorcycle was to be driven solo, primarily on the mountain or with a sidecar. The information on the maximum speed, which ranges from 95 to 135 km / h, is correspondingly different.
The power is transmitted to the rear wheel via a cardan shaft made of spring steel. Since its center piece is designed as a torsion bar , another measure to absorb torque surges, for example from a Hardy disk , is unnecessary.
Frame and chassis
The Victoria Bergmeister has a double tubular frame made of seamlessly drawn steel tubes , which is considered to be extremely torsion-resistant and is specially designed for sidecar use. The front wheel is guided on a telescopic fork (also swing arm in the experiment ), the rear wheel on straight-line suspension . In motorsport, the plant also used versions with a rear swing arm. A rubber silent block (rubber part vulcanized between metal plates) springs the saddle. The full hub brakes with a diameter of 180 mm and a pad width of 30 mm are generously dimensioned for the time, but are also essential for sidecar operation (with the sidecar wheel braked).
Furnishing
The Bergmeister's standard equipment includes a large headlight with a built-in speedometer and electrical idle speed indicator (which is switched via the gearbox contact), a box on the left of the rear wheel to accommodate the battery and a toolbox on the right, as well as standardized connections for a sidecar. The footrests are adjustable and can be adjusted to the gearshift lever in a foot-friendly manner. There is a light under the tank so that repairs to the engine can be carried out during a trip, even in the dark. A flat 15-liter tank or a narrow and taller 18.5-liter sports tank was optionally available.

The model name "Bergmeister"
The type KR 6 was already called "Bergmeister" after Victoria won the European Hill Climbing Championship for sideboards up to 600 cm³ in 1932 with such a motorcycle. The KR 6 has a transversely installed 2-cylinder boxer engine with a capacity of 600 cm³ and a chain drive, so the two cylinders are one behind the other - viewed in the direction of travel.
Remarks
- ↑ On BMW models from the 1950s, the manual gearshift lever is on the right-hand side, so it can be fully used while driving. In the German standard DIN 73005 control lever and wheel installation on motorcycles from May 1940 "foot control for all motorcycles was prescribed. In addition, a manual gearshift lever must be available to operate the gearshift under special conditions on motorcycles with 250 cm³ displacement and above"; this standard was in force until March 1970.
