there are 2 classes that CBR250 can join.
1. OMR CBR250. all cbr250 compete become the first.
2. National championship. Kawasaki ninja 250 and Cbr250 compete become the first. basically this class is for honda and kawasaki factory team.

omr250 class has limited regulation on engine, therefor we maximize it on suspension etc.

this is CBR250 Astra Racing Team facebook who won last year all seasons championship.they are Factory team.
