Yes...the 70’s were the heyday of Triumphs, BSA’s, Nortons, and the other Brit Bikes.
I actually saw a Royal Enfield with a sidecar on the road last month! (TWICE!)
I took a spin on a Royal Enfield one. Can only compare it to a tractor. Only the shifting, clutching and braking took getting used to. That was a different animal.
I bought a new 72 Norton after hearing my buddy’s bike. Sold it a few weeks later when the oil leak from the points cam kept fouling it.
