The Tsars Motorcycles (continued)

Leave a reply

Motorcyclists and Comrades of the Russian Empire celebrating Easter. Two motorcycle rear wheel stands helped in making of a table.

1914 or 1915 Indians. They’re both Hedstrom engines, so 1915 or earlier models, not 1916. It’s a time of the First World War, the photo could be taken at any time during WW1 after 1915. The Tsars collection of motorcycles was growing.

Vodka on Easter, a fine family tradition!

Nicholas II or Nikolai II Alexandrovich Romanov, known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer, was the last Emperor of Russia, King of Congress Poland and Grand Duke of Finland, ruling from 1 November 1894 until his abdication on 15 March 1917.

The tsar was a forward-thinking man, and was aware of the industrial revolution that would sweep all before it, and as Juris said, the motorcycles ALWAYS go first!

There are several accounts of what happened, and historians have not agreed on a solid, confirmed scope of events. You can do your own studies.

Railcars

Leave a reply

The engines were put to many uses, stationary engines such as water pumps, generator sets, and the like. Another use was the railcar, a so-called motorized “draisine”, a light auxiliary rail vehicle, driven by service personnel, equipped to transport crew and material necessary for the maintenance of railway infrastructure or for other purposes. Because of their low weight and small size, they can be put on and taken off the rails at any place, allowing trains to pass.

This image shows the various things a carburettor goes through from idle to full throttle.
The throttle slide cutouts are in particular important, as they govern the transition to main jet, often the cause of a hiccup.
Some people go the measure of smoothing the cutout.

The rarest and most important motorcycle KMZ M-53

The rarest and most important motorcycle KMZ M-53.

Today (30/10/2022) I will show you the most mysterious and most significant model of the Kiev motor plant – the 500cc M-53. This motorcycle was developed by a team of KMZ designers under the leadership of M. A. Pozdnyakova in the mid-1950s and demonstrated a sharp deviation from the M-72 concept.
Alas, 500cc M-53 never went into series production, but many solutions of this motorcycle were implemented on M-72N, K-750, K-650 and defined the principled differences between Kiev motorcycles and Irbit motorcycles.
See the video for more details about this specimen. This is the debut of the M-53 in video format, before that we could only see rare photos of this model.

In this video, I’ll show you a real 1956 KMZ M-53 motorcycle from Alexey Popov’s collection. This is not a replica, but one of the few copies of the M-53 that were produced in those years. This is not just another experimental motorcycle. No, the M-53 actually determined the architecture of future KMZ motorcycles for many, many years. It was equipped with a 500cc overhead valve engine with a capacity of 28 hp, had a weight of 190 kg and only slightly surpassed the IZH in this parameter. The maximum speed of the M-53 was declared over 100 km/h, and the fuel consumption was about 4.5 l/100 km. But the KMZ M-53 did not go into series production.

But most of the decisions were subsequently implemented on the K-750, K-650 and even on the Dnieper-10-36.

Here is the bombshell! Very original and very beautiful and very stylish!

See the video!

BMW R 71 was the Icon of BMW

Leave a reply

from Motorworld by V.Sheyanov

The first thing I want to write: R71 is the legendary BMW top model with a 750cc side-valve engine which became the basis for the Soviet military M72, which distant successor of which is still being produced (*in China). And this statement should be the end of the article. But “the devil is in the detail”. The German BMW R71 motorcycle, presented to the public at the1938 motorcycle exhibition in Berlin remained an “unattainable standard” for its Soviet counterpart.

Serial production of the R71 motorcycle was launched in 1938 and lasted only 3 years, until 1941. Technically difficult, the R71 gave the impression of a very simple machine – thanks to the high-quality standards and the tremendous work that BMW engineers and designers put into the new line of their motorcycles.

In the military training camps of the Wehrmacht, we could find both models – the simpler BMW R12, which had been in service for several years, and the conditionally “tourist” R71, which was equipped with a more perfect and lighter frame with variable section tubes, soft rear suspension, and more powerful 22 hp engine with a compression ratio of 5.5:1. Nevertheless, despite the obvious advantages, the R71 didn’t become a bestseller. The army needed a low production cost instead of a machine with a high-class manufacturing accuracy and one of the most advanced, but expensive frames on the market offering high comfort.

The BMW R71 became the last side-valve motorcycle in the history of the Bavarian brand and the last one that could be equipped with a hand gear lever at the request of the buyer.
A total of 3 458 R71 motorcycles were produced, most of which were destroyed in the war.

footnote: The Ural, now being manufactured in Kazakhstan (2022) as a sidecar rig is a direct descendant of the old R71!
