Excellet point here for newbies.
This friend of mine started riding m/cs as soon as he came over to Cdn (from the UK) in 1945 on a 98cc, then a 125 & finally up to a 350cc AJS 4-stroke single then had to give up to support a family.
Back to riding in late 80s with a used 400CC twin & by next yr bought a good 'used' BMW & later a NEW 1000cc Beemer-----here is a rider with experience that even when he went back to riding with experience to feel out what it was like to ride again on a sort of guttless used 400. At 76 yrs of age he is still riding & in his complete life has never had a m/c accident or a cage accident. A rider with the OLD SCHOOL OF LEARNING being a step by step in time!!!!!!
