Maybe that's half the problem Paul R ? They sort of had two wheels of some description in the past, but without the c.c. graduation process?
I was a biker from '56 starting, Coventry Eagle 98cc, BSA Empire Star, 250cc, Triumph Tiger 90,350cc, AJS,350cc, Triumph T21, 350cc, Norton Dominator,500cc, Inter Norton 500cc,
BSA A7 Shooting Star 500cc, A10 650 Super Rocket, Triumph Thunder Bird 650cc,Triumph Tiger 100, 500cc, Tiger 110, 650cc, and a few more beside?
: Still reckon there comes a calendar point for most folks, not all, when bikes, especially some of the modern day projectiles, are way beyond their physical and mental competences.
Still, if you fancy one, go for it, not for yours truly, thanks, with the over congested roads, and 'loonie's' with limited vehicle experience that use them.
I started with bikes, then Tanks, Armoured Cars, HGV's, Buses, Etc.
so I suppose I am a reasonably experienced driver, but not a particularly good one, or one who thinks he is??
