The case for Kenny Roberts
Three consecutive 500cc world championships from 1978 to 1980, the first of them as a rookie, from a career of only 60 Grand Prix starts. Roberts took 24 wins, 22 in the premier class, and 44 podiums, having already won back-to-back AMA Grand National titles in 1973 and 1974 and completed the Grand Slam of victories across all five American dirt-track and road-race disciplines. His influence outweighs his totals. He imported dirt-track technique to Grand Prix racing, deliberately breaking rear traction to steer a 500cc two-stroke, and every rider since has ridden some version of that. Off track he was equally consequential: his threatened breakaway World Series in 1979 forced the FIM to improve circuit safety and lifted rider payments dramatically. He later ran his own team and built his own three-cylinder 500cc machine.
The case for Jorge Lorenzo
Five world championships: 250cc in 2006 and 2007, and MotoGP in 2010, 2012 and 2015. Lorenzo took 68 Grand Prix wins from 297 starts, 47 of them in the premier class, along with 114 premier podiums and 69 career poles. He is the purest exponent of the corner-speed style that Yamaha's inline-four M1 rewarded, a rider whose lap times could be laid on top of one another for an entire race distance. Two moments define him: riding at Assen in 2013 two days after surgery to plate a broken collarbone, and the 2015 championship, won by five points from Rossi in a season that ended in open hostility. His Ducati years from 2017 to 2018 were slow to start but produced three wins once the bike was adapted to him, before a difficult final season at Honda.
