Hot Cams Camshaft for Honda CRF 450 R 2010-2016 1259-1

Stock camshaft profiles limit your CRF 450 R's potential, leaving horsepower and throttle response on the table. The HOT CAMS 1259-1 delivers measurable gains across the powerband while maintaining compatibility with your existing valve springs—no spring upgrade headaches or machine work required. Choose your power curve: Stage 1 for aggressive low-end torque or Stage 2 for peak horsepower that pulls hard through the top end.

Both profiles feature HOT CAMS' Improved Throttle Response (ITR) technology, giving you sharper, more predictable power delivery when you roll on the throttle. Whether you're dialing in a motocross setup or maximizing performance on closed courses, this is a straightforward bolt-in upgrade that pays dividends on lap times.
