In my opinion this is the most beautiful Grand Prix road racer of all time. It is the Cagiva 500 which was raced by several Americans, Randy Mamola, Eddie Lawson, and John Kocinski. Not a lot of advertising on the bike. I saw Randy Mamola race it at Laguna Seca in 1990 and Eddie Lawsn race it at Laguna Seca in 1991. I actually got to see it close up in the tent at Laguna Seca in 1990. A team member loved my Randy Mamola T shirt with him on the Cagiva.
