Note the over the fender support and the lack of a sidecar entrance step. (This is a Chinese CJ-750, however.)

 

An older military sidecar.

Note machine gun mounts: plural.

 

 

A unique feature of Soviet plunger suspension bikes that BMW R-71's didn't have is a re-inforcing gusset. The oldest re-inforcements at the plungers, to cope with stresses from poor Soviet roads and terrain, are perfectly triangular.

 

Later ones had curvature like this.

 

These were the most plentiful M-72's ever built. The "M" models were actually civilian variants and not military as one might assume. Some of an M-72's defining features are a high mount front fender, rear fender support loop from the bottom of the plunger, an fill hole on the side cover of the final drive (not the rear of the FD housing like all other M-72's) and castellanated (bottle-cap) wheels with holes in them (not pictured here, but visible on the M-61 and M-62 pictured below).

 

 

Visually the same as an M-72M except for a 650cc OHV engine, modern telescopic forks, a taller rear plunger, and KMZ/Dnepr K-750 style knee pads with concentric ovals.

 

The M-61 (and maybe some M-72M's) was probably the only model to ever sport this sticker ("Irbit" in cursive Cyrillic). At any rate, it was certainly the last.

 

The M-62 was the first Ural to actually carry the Ural name.

Basically an M-61 with new fenders, upper fork shrouds, and a rubber cushion under the seat instead of a spring. Maybe the inspiration for the Ural Retro?

 

The first Ural to use a rear swingarm suspension. Notice that unlike the KMZ/Dnepr bikes, the swingarm is on the outside of the frame. However, the M-63 still used the older style gas tank.

 

 

 

Visually, an M-63 with the newer style tank with white trim.

 

The first of the "modern" Urals. Notice the straight frame with no arch at the the upper shock joint.

Basically, the same frame in use today.
