Suzuki’s 2022 motocrossers are the exact same as last year.
The last time the RM-Z450 received a major overhaul was in 2018. Since then the bike’s only mechanical updates came in 2019 in the form of a lighter-rate shock spring and different damping settings for the fork and shock.
The RM-Z250 has featured no mechanical changes since its last revamp in MY19. As for the RM85, it has not enjoyed performance revisions in several years.
