yep its organized by dgsport, same people
ride down in one day? gee. back in 99 i had a superblackbird on loan and even if you could do then 140 mph or more on the french autoroute without much problems with the gendarmerie, I didnt manage to do london - florence in one day...
the superblackbird would do exactly 120 miles per tankfull when "cruising" at 120-130 mph.... so had to stop once an hour exactly each time, for gas (and coffe) so at the end was equal to 80 mph i guess !
alex, its a four hour thing and if it gives you an extra incentive, you'll be up against all of our national teams, quite a few fast people in there like Samuele Sardi & Oreste Zaccarelli who took third in the last Bikers classic. cut off date is 1980 so your DOHC should be ok.
if you need a rider just let me know....
