having read through all this i may just may have found what most seem to want.a level playing field.yes?well you never going to get it.unless you go back to junior school where egg and spoon races are banned..you could do what suzuki do with the gsxr cup.all the same machines and u draw by lot which one u get.it seems to be about getting a replica.if you dont get one your not riding fast enough and should take up something else.or just ride and enjoy it.derek minter went round at 100 miles an hour nearly60 years ago on a circuit which was nothing like the motorway you have now.and on tyres you would reject for going to work on.and with brakes that faded coming down the mountain leaving little to stop for governers.and no 90 bore motor....for me bring on the mv and everything else lets have some variety..im off to read my poster by h.l.daniell that lap at 91 in 1938..bet he got some reps...he once said i would be a good rider if only i would let the brakes off !but i got a rep...
