Yes it was "electric assisted starting". After my time at N-V, but I did follow that particular development.
As a resutl of the research conducted for the space program, there were major developments in the flux strength of permanent magnet materials, specifically the rare-earth magnets. These improved the torque of starter motors by an order of magnitude. My son-in-law picks up computer peripherals from places like the Salvation Army Thrift Stores and strips them down for components he can use for other things. You should find a magent out of a disk drive some time, and stick it to your fridge. You'll need a chisel to break it loose!
The Norton twin is a real bear to turn over, and Lucas didn't develop their starter to use rare earth technology before the Commando was history. As I've mentioned in other posts, Norton was a minor player and Lucas seemed to "condescend to doing business" with us.
It's fortunate that some of the other manufacturer's bits fit, When you're pushing 70, (I'm not dragging it behind me just yet) kick starting a Commando would really be difficult. Having a high-torque, relable starter motor would be a real boon.
When I think of some of the J. Michael Mouse electric starters of the past, the mind boggles. A lot of Villers engines were equipped with a system called a SIBA Dynastart, where the starter motor was switched tp being the generator once the engine was running. A college buddy had a "Maicoletta" scooter, which had a weird starter that rocked the engine against TDC until it fired. Problem wasm since it was a side-port 2-stroke, it could easily start the wrong way. Quite a surprise to put it in gear, drop the clutch and take off backwards!
That happened to me when riding a works 360 motocross bike (on Trade plates) in Wolverhampton traffic. I was approaching a tradffic light when it went red. I snicked the transmission into neutral and started braking to a stop. The engine promptly quit. I had just enough speed to drop the clutch to restart the engine and shifted into neutral. An older half-cab double decker bus pulled up behind me, the kind with the big radiator out front with the big "Leyland" logo. When the light turned green, I selected first, opened the throttle, let go the clutch, and the bike took off backwards. The "Scrambles" knobbly tyres tried to lock into the radiator hoeycomb of the bus and climb straight up. Fortunately the bus driver had quick reactions and managed to avoid flattening me.
Electric start is something British motorcycles should have had from the early 1960's. Small cars (the 850cc Mini for example) had the typical car-type Bendix system, so why not bikes?
Another marketing feature and very useful capability frittered away by the "We macho bikers don't need it" attitude combined with a lack of courage by the suppliers!
