For race fans, the American International Motorcycle Expo in Columbus, Ohio, is a den of temptation and allure. Within a hand’s reach are today’s most lauded roadracing machines. These bikes represent the pinnacle of two-wheel technology and overwhelm the eye with pristine welds, exotic milled metals, and carbon fiber so perfect it should be in a museum. More than that, these bikes are pieces of motorsport history, contributing to the never-ending wheel of racing lore and legend. Here are a few of the most notable bikes and parts that make us go weak in the knees.

What lies beneath? With the hint of the oval intake at the front and the round exhaust at the rear, race fans knew it would be the KTM RC16, the manufacturer’s MotoGP weapon and the pride of Austria.Seth Richards

Behind the stanchions sits Pol Espargaro’s bike—or at least one with his number 44. As we await to hear Bradley Smith’s future after a lackluster tenure with the rapidly improving RC16, it’s no surprise the hard-charging Spaniard is KTM’s current lead rider.Seth Richards
