Challenge of the Americas Ruling on Engines Permitted for 2021

Challenge of the Americas is moving forward with the same class structure for the 2021 season as the series contested in 2020. The ROK Cup USA and the ROK Promotions announced on December 16 a move to Vortex-only engines for their events in 2021, including the upcoming Florida Winter Tour. FTK Promotions owner Andy Seesemann confirmed with eKartingNews that the engines allowed for the 2021 Challenge of the Americas will not be changed from what has been published, more specifically the 100cc divisions.

“Our class structure is moving forward unchanged,” stated Seesemann. “The 100cc categories will include both the VLR engine and KA100, with the remainder of our categories following the ROK Cup ruleset. Of course, we have adapted to the new LeVanto KRT as the spec tire for all categories in 2021 and I look forward to its debut at our opening event in roughly one month.”

Seesemann added the many teams and competitors have received their first shipment of LeVanto tires, hitting the track for initial tests. Reviews have been very positive about the new tire for all divisions. The spec fuel will be Sonoco Supreme with Motul Kart Gran Prix as the spec oil for 2021.

Registration is now open for the first two rounds of the 2021 Challenge of the Americas on January 22-24 at the Phoenix Kart Racing Association in Glendale, Arizona.
