Is it going to be Argentina or Austin on Sunday at Silverstone? Two of the bumpiest circuits of the first half of the season had very different outcomes.

At the Termas De Rio Hondo circuit, Marc Márquez took off like a scalded cat to try to take the win, and claw back the valuable points from Maverick Viñales he had handed him at Qatar.

In undulating Austin, Márquez rode his usual imperious race to take victory, while it was Viñales’ turn to make a silly mistake.

The perils of a American bumps were rather bike-specific. It wasn’t just Marc Márquez who crashed out of the lead in Argentina, Repsol Honda teammate Dani Pedrosa managed the same feat.

Cal Crutchlow rode cautiously to finish third, while there were four Yamahas in the top six. At Austin, Márquez won, Pedrosa finished third, Crutchlow fourth. Valentino Rossi’s charge came too late, and he finished well behind Márquez. A year earlier, it had been Rossi making a silly mistake in Texas, and slipping off.

So how does Silverstone compare to the two American tracks (North and South)? In Austin, the bumps were on corner exit, Maverick Viñales explained, whereas at Silverstone, the bumps are on corner entry.

“So it seems more difficult to ride,” the Movistar Yamaha rider said. In Argentina, it wasn’t so much bumps as massive undulations which were causing the problems.
