I've been a biker since before the enforced helmet law.
My current steed is a 1960 Norton Slimline 99 600cc.
Previous beasties from first to last have been Triumph Tiger Cub, Honda CG125, Honda RS250, Kawasaki Z400/4, BMW R80RT, Ducati ST2, Honda ST1100, Triumph Speedmaster, BMWR100RT.
Now I stick to my all time fav and inflation buffer, my good old Norton that only goes out when the weather is good coz I'm getting to old to be cold.
