Indeed, as was most of the Brit Iron .... as a pal once said to me
"They were crap in their time and haven't got any better with the passage of time"
BSA produced the A50 and A65 for instance, making the old A7 and A10 unit construction, but they had their collective heads in the sand and didn't address the oil feed problems to the mains and big ends .... a familiar legacy unfortunately of most of the British Motorcycle Industry post war
Devimead were to sort the problem of oil supply to the mains quite successfully
Hindsight is an exact science .... if I'd kept the Arial Square Four, the Rocket Gold star, the Velocette Viper, the Sunbeam S7 (I bought for eight pounds ten shillings, complete with spare engine and drive shaft) .....
They were crap but it was all we knew at the time
For me, today,
G650XC (any of the triplets)
Versys
Yamaha TDM
VFR 750
SV650
