My old man was a staunch british motorcycle fanatic - that was until i got my first proper motorbike - a very handsome kawasaki Z650. This piece of "jap crap" as he put it did not upset the old lady by dripping oil on the driveway, it had decent baffles, DOHC, 120mph plus - in 1977, electric start, and no need to "gunk" the filthy engine every week.
Anyway, after seeing my fine machine he was straight away converted to the "jap crap" and bought a yamaha RD400 which he swapped with me and eventually he retired with a German BMW RS1000 - and imo a very nice ride indeed - well balanced (bit ugly though).
In recent times Triumph and Norton have brought out some great machines, - although, if these companies are still British owned I am unsure.
just a bit of a waffle by OT....
