The TM (ICC) was brought into the U.S.A. by TM Racing USA. in approximately 2000. The TM (and other ICC’s) are still in the U.S. and is very much alive and well. I do service on many and am keeping busy. At local tracks the ICC and moto run together to complete the shifter class. On a national or regional basis the Spec Honda has pretty much taken over on the sprint track. In the mid west where long track is popular there are more ICC’s in the field. The east coast is very well represented with the ICC now referred to as KZ.
