In mid-2016, Thumpstar made its return after constant demand to revitalize the brand in the USA. Thumpstar made its debut with the TSX 125cc LE and TSB 70cc in July 2016. Then in January 2017, Thumpstar expanded the offering to include the TSB 125cc, TSX 125cc LEM, TSX-C 140cc and TSR-C 160cc models. The 2017 models display Thumpstar's signature color, Chartreuse, a part yellow, part green mélange. The TSX 125 LEM is a limited edition model with genuine Marzocchi forks, and the TSX-C 140cc and TSR-C 160cc are for competition use on closed course tracks.
