The Ural M-62, built from 1961 to 1965, was the second step of the 650 cc generation. A new camshaft and an automatic ignition advance mechanism lifted power to 28 hp, the gearbox was rebuilt with gear couplings instead of dog clutches and the suspension travels were increased.

History of the Ural M-62
More power, better gearbox
From 1961 the factory built the M-62 in parallel with the older M-61. The new motorcycle received a new camshaft and an automatic ignition advance mechanism, which added 2 hp for a total of 28 hp (20.6 kW) at 4,200–4,800 rpm. Instead of dog clutches the gearbox now used gear couplings and was unified with the gearboxes of the Kyiv plant’s motorcycles. The suspension travels were increased and the shape of the front fork covers was changed.
The outfit in numbers
With the sidecar the M-62 measured 2,420 mm long, 1,650 mm wide and 1,100 mm high, on a wheelbase of 1,435 mm and a track of 1,130 mm. It weighed 320 kg and could carry 255 kg, reached 95 km/h and used about 6 litres of fuel per 100 km. The electrical system was 6-volt, with a 3MT-12 battery, and the tyres were 3.75-19.
Design and features
- 28 hp: the automatic ignition advance and new camshaft gave 2 hp more than the M-61.
- Gear-coupled gearbox: four speeds with gear couplings, unified with the Kyiv-built motorcycles.
- Longer travel: more suspension movement front and rear for poor roads.
- Sidecar outfit: 320 kg, 255 kg payload and a top speed of 95 km/h.
Ural M-62 versions
- M-62 (1961–1965): the standard sidecar motorcycle.
- M-62K: a cross-competition version built by the factory for racing.
The M-62 followed the M-61 and was replaced by the M-63; the whole family is covered on the Ural 650 page. More machines are in the Ural collection.
