The 2025 450 SMR is based on the updated 2025 450 SX-F and receives frame changes that save about 300 g. It gains an adjustable 48 mm WP XACT fork, a revised rear linkage, new tank shrouds, a one-piece inlet sleeve and full-orange bodywork. Metzeler Racetec SM K1 supermoto tyres on Alpina rims and smaller footrests for more lean angle complete the package.
