The number 40 machine is the 1982 Honda NS500, powered by a 498.6cc liquid-cooled, reed-valve 112 degree V-3 making 120.3 horsepower @ 11,000 rpm, weighing in at 260 pounds. This was Honda's first liquid-cooled two-stroke triple. Spencer won his first GP, over Barry Sheene, then-world champion Franco Uncini, Kenny Roberts and Randy Mamola, on this bike on July 4 at Spa-Francorchamps in Belgium, where he also set the quickest lap of the race. Next to it is the last NS500 made for Spencer in 1984 and the bike he rode in defense of his 1983 title; same basic specs, but with 125.8 horsepower @ 11,000 rpm and weighing 249 pounds. That bike was rolled out because of the disastrous NSR500 "upside-down" four-cylinder experiment.
