#motocross #test #sports #bike MXA's Josh Mosiman and Josh Fout test the new 2025 Kawasaki KX450SR "Special Racer" model at Glen Helen. The update list is impressive on this bike. It has a modified cylinder head with polished intake ports, Pro Circuit Ti-6 titanium exhaust system, optimized ECU settings, Kashima coated forks with stiffer valving and an extra 4cc of oil, plus the rear shock has Kashima coating and model-specific settings as well. Of course, it features the XTRIG Rocs-Tech triple clamp with PHDS (Progressive Handlebar Damping System), Renthal rear sprocket and D.I.D ST-X rims, and D.I.D gold chain. We break down all the details in this video, our likes list, our quibbles, and what it feels like on the track. Subscribe to Motocross Action: https://hi-torque.com/product/subscri...
