Unrestored original team

Content of

The original paintwork of his Victoria KR 6 team was applied in 1929, and Volker Mollenbeck takes care of its faded, scratched remains with great devotion: he cleans as rarely as possible.

NA motorbike that has aged in honor and for that very reason has been visibly taken along with the right understanding is not everywhere: When a photographer wanted to get a better view at a veterans rally, he quickly got on a team parked next to him. Its condition, it seemed to him, required no special respect. The owner, however, saw it differently, found very energetic words and sent the fleeing photographer afterwards that he should rather climb on A-1 restorations in the future, they could at least be restored to their previous condition. “But that was a long time ago”, laughs Volker Mollenbeck, proud and convinced owner of the said tricycle, “today unrestored originals like my 85-year-old Victoria KR 6 enjoy great recognition.”

Victoria KR 6 was considered the ideal tractor

Thanks to its smooth boxer engine, the robust Victoria KR 6 was considered the ideal tractor. A top product in German mechanical engineering, especially with the 600, which made its debut in the KR VI in 1927. Compared to the previously used half-liter, the bore had grown from 70.5 to 77 millimeters with an unchanged 64 millimeter stroke, and the power increased by six to 18 hp. Worthy of honor, certainly, but in comparison with the corresponding ohv boxers from BMW, the limits of the concept gradually became apparent towards the end of the 1920s: In the Victoria KR 6 engine with a transverse crankshaft, the housing and magnet shadow the rear cylinder the Munich competition are both in the cooling wind. Which was not to be expected, because when BMW man Martin Stolle designed the first motorcycle engine for his employer in 1919, he copied with Chinese audacity, as is well known, the also transversely mounted flat twin of the then much admired English Douglas. The first large-scale buyer of the two-cylinder engine, baptized M 2 B 15, was Victoria from Nuremberg from 1920 onwards. She became rich and important with bicycles, but was also active as a manufacturer of cars and motorcycles before the First World War.

It was very unpleasant that in 1923, immediately after the appearance of the R 32 fitted out by Max Friz with a longitudinally installed boxer and shaft drive, suddenly no more engines were sold to competing manufacturers. Which moved Victoria to hire the clever engineer Stolle, who was divorced in a dispute with Friz. He came with a bag full of new ideas – and his ohv head for the BMW engine, produced by the Munich company Sedlbauer. The Victoria KR (for motorcycle) I with the M 2 B 15 was followed at the end of 1922 by the II with its own drive, initially manufactured by Sedlbauer, and nine instead of 6.5 hp. With the III, a three-speed gearbox moved in from 1924, the output grew – of course – by three hp.

Could be ordered from the factory with a sidecar

Then the 600 KR VI, which was modernized in language in 1928. So that it fit into the grid of the recently added smaller sisters KR 20 (sv single cylinder) and KR 35 (ohv single cylinder, both from Sturmey-Archer), from then on it also used Arabic numerals and was called Victoria KR 6. Drivers – some with JAP engines – are still great successes, and that’s why the Victoria boxer story culminated in a sports version with two carburettors, encapsulated valve trains and 24 hp. At the same time as the triumph in England, Victoria also planned to switch to large parallel two-cylinder engines. Unfortunately, the engines, which were again drawn by Martin Stolle, plagued serious start-up problems, and so the boxers remained in the range until 1936. As was common with many manufacturers at the time, they could be ordered with a sidecar from the factory, and Victoria even had a teardrop-shaped boat ready for the sports driver based on her own victories.

Spacious touring sidecar on the Victoria KR 6

Volker Mollenbeck is more relaxed, his Victoria KR 6 pulls the spacious touring sidecar. It has a nice entrance door and a respectable luggage compartment under the lid that folds out to the rear, which can also be used as a ride for children. The construction of the convertible top offered by the factory shows a real joke, which when opened acts as a windshield, but when closed rises high above the passenger and then not only allows side views, but also has a small viewing window in the direction of travel. The boat – a wooden construction wrapped in oilcloth and slightly lighter than the sheet metal counterpart that is also offered – rests on a triangular tubular frame, which in turn is held at four points on the motorcycle frame. The sidecar looks elegant and light, thanks in part to the transverse boxer, the entire vehicle is quite narrow. The vehicle documents show an empty weight of 268 kilograms (which is quite high), and that makes the Victoria KR 6 from Volker Mollenbeck astonishingly easy. Your mechanically smoothly running engine must produce well over 18 hp, so easily does it increase speed, so persistently does it advance in the third and last gear of the manual transmission.

“I took it over so quickly”, the qualified engineer for wood and plastic technology rejects any suspicion of tuning and reports of fluctuating performance data for the Victoria KR 6. “That ranges from 18 to 22 hp, with mine I go from a good 20 PS off, the way it runs. ”Well, and it still runs like that today, because inside – unlike the external appearance – parts were sometimes exchanged. When Mollenbeck took over Victoria, it was cleaned extremely gently with petroleum and then partially treated with Ballistol. The engine ran, it actually ran really well, but with an old sweetheart you never know. Completely disassemble. The Mahle company supplied new pistons, those for the heat-sensitive rear cylinder with significantly more clearance. The tappets and pans of the rocker arms required refreshment, and Mollenbeck pressed hollow steel balls into the pans. “Holds up to this day without any problems.” He re-ground the valves and re-centered the oil pump rotor. The crank drive remained untouched “because it looked like new.” A machine fitter manufactured new linings for the optionally hand or foot-operated multi-disc clutch. Victoria’s own gearbox can be a little bit tricky, the sliding blocks of which tend to tilt and then block the waves. So Volker Mollenbeck made new stones and optimized their width.

Victoria suspension fork reliable and comfortable

There was almost no work on the chassis. Re-apply the brakes, insert the spokes where necessary, done. The patented Victoria suspension fork has proven to be as reliable as it is comfortable, in principle a mixture of parallelogram and telescopic fork. At the top, the fork legs have an approximately ten centimeter long slot on the inside into which the ends of the upper cross connection protrude. These act on springs stuck in the bars, one each on tension and one on compression. The horizontal movement of the fork blades is mitigated by small springs in front of and behind the upper cross connection. One of the better forks of its time that also requires little maintenance. The rims have bulbous strips in balloon format. “They were already available on request back then, and the normal format is too weary for me,” explains Mollenbeck, who now and again fetches his Victoria KR 6 out of the garage for short tours. He also attends one or two meetings. “But since many old friends have preferred to stay at home, the number has decreased.” The 67-year-old is easy to talk: Unlike many of his friends, he owns a motorcycle that proves every day how long you can run, even if the paint is almost on is off.
