Nobody likes to be considered to be among the slowest bikes on the track, least of all Honda. But, when CRF250 sales dipped 27% in 2017. Honda was ready to retire the old warhorse. Luckily, Honda had an all-new bike waiting in the wings for 2018. How new? It shares almost nothing with the 2017 CRF250 and almost everything with the 2018 CRF450.
