RM-Z450 underwent a massive facelift with aggressive styling that mirrors the RM-Z450WS that the MXGP race team ran, SHOWA Spring forks? Yep. First production bike with SHOWA’s BFRC rear shock? Yep. More power? Yep. New Frame? Yep.
2018 RM-Z450 underwent quite a few mechanical updates to the engine that were also matched to an improved ECM and an updated S-HAC system, biggest change comes internally with the removal of the cross support within the tube. This not only improves cornering performance, but also aids in the absorption of shock to the frame, translating to a better feel at the rider’s hands
