Honda's Muklada Sarapuech will compete in the Supersport 600cc class.

The 2021 OR Bric Superbike series begins this weekend at Chang International Circuit in Buri Ram.

Circuit managing director Tanaisiri Chanwittayarom said this year's championships should be more exciting because many events overseas have been cancelled due to the Covid-19 pandemic so a lot of leading Thai riders have opted to compete in domestic tournaments.
