The solution to the main bearing problems was the much-fabled bearings designated "Superblend" by Norton in a 1972 Service
Release. These bearings were a 'special' with additional crowning, marked 6/MRJA30 and made by R&M (later RHP). Early in 1973 a superseding service release referred to Extra High Capacity Main Bearings. These were in reality just a higher load capacity roller bearing NJ306E made by FAG. The piston issues were resolved by removing the slot for oil drainage behind the oil ring, and drilling a series of holes instead, so that the piston crown didn't separate from the piston at higher

The high performance Combat engine gave 65 bhp (48 kW) at 6,500 rpm using 10 :1 compression ratio. It was too much for the stretched old 1948 Model 7 497 cc-based design, with main bearing failures and broken pistons being reported in the press, along with quality control issues.

traditional single cylinder four-stroke models were finished. Matchless and AJS badged models, with Norton motors, were assembled till 1969. In 1968 all models had new carburettors, ignition systems and an ignition lock. The G15CS, N15CS and M33CS had improved cycle parts for 1968–69.

Triumph motorcycle activities. The government offered a financial rescue package contingent on a merger of the two groups and

The 1969 Commando S was introduced fitted with a high-level left-side exhaust and a 2.5-imperial-gallon (11 L) petrol tank, primarily aimed at the export (US) market. The original model was thereafter referred to as the
