The 2018 MotoAmerica season will welcome the introduction of the all-new Twins class, a category based off of popular lightweight street models. Besides giving fans the chance to watch more on-track action, the Twins will allow riders, teams, and OEMs the opportunity for more involvement in the MotoAmerica Championship.

The class will play host to several 600cc to 800cc twin-cylinder bikes, with a rule package designed to allow freedom to builders and small shops to make their own modifications and custom builds. Engines can be extensively modified, as can some of the chassis components, and an open-ECU rule will make for a tuner’s dream. Low minimum weight limits add to that – also being the reason for strong power-to-weight ratios and undoubtedly quick lap times.

“…an open-ECU rule will make for a tuner’s dream.”


Racing alongside the rest of the MotoAmerica Championship, the Twins class will compete in nine out of the 10 scheduled events, with its debut taking place at the preseason test at Barber Motorsports Park, March 26-27, before its first official race at Road Atlanta in Braselton, Georgia, April 13-15. The Twins will be on track for two days each race weekend, with practice to be held on Friday and a single race scheduled for Saturday.

With similar class structures proving successful on the club racing scene for several years, the Twins is sure to be a popular class among amateur racers and local shops nationwide. There is no doubt that a new group of teams and riders will emerge to fight for the inaugural Twins title. And like we’ve seen with the KTM RC 390 Cup (now the Junior Cup), lightweight racing is some of the closest racing there is over the course of a race weekend.

With no official name for the Twins class yet, we’ll be turning over the naming rights to MotoAmerica fans next week. Stay tuned. Also, stay tuned for part two of MotoAmerica Twins Class Explained.
