2025 Honda CRF450RThe Honda CRF450R has been turning heads at the track for over 50 years. This Honda 450cc dirt bike has plenty of low- and midrange torque, giving riders faster corner exits and the ability to pull taller gears on the track. The CRF450R is a winner! Honda GDR racer Dylan Wright rides the CRF450R, and took home his fourth Triple Crown Series championship in 2023. The chassis is robust and results in great stability, optimized suspension performance, and tight handling. As a bonus, its muffler is strong, helping to prevent excess noise from your bike. Features may include: Engine & Drivetrain 450 cc Unicam EngineHonda Unicam cylinder heads combine the best of single- and double-overhead-cam designs. The configuration contributes to a compact engine that saves weight over a comparable dual-overhead-camshaft motor and also permits a narrow included valve angle. This flattens the combustion chamber to facilitate ignition flame propagation, allowing a high compression ratio. Since less space is taken up in the cylinder head, the camshaft sits lower in the head for a more compact engine and a lower center of gravity. Smoother AirflowTo help the CRF450R breathe more freely, engineers redesigned the entire air-intake system. A new airbox, new filter position, and new intake funnel combine to reduce restrictions to airflow. The result? Better throttle control and more consistent power delivery. Revised ExhaustIn combination with its less-restrictive air-intake system, the CRF450R’s revised exhaust with straighter airflow means smoother engine operation in the mid- to high-rpm range and more-controllable acceleration. Chassis & Suspension New Aluminum FrameThe CRF450R’s aluminum frame has been radically improved for 2025 with the aim of increasing rigidity and stability. Using 70% new components, Honda engineers have managed to improve torsional and lateral rigidity in every direction, resulting in more-controlled and predictable handling — particularly in rough conditions. Improved Showa ForkTo complement the new frame, the CRF450R also boasts an extensively revised Showa spring fork. Everything from the outer tube to the axle was rethought and redesigned, resulting in improved low-speed damping, reduced friction, and enhanced rigidity. It all adds up to better control and lower lap times. Easier Shock AccessWhen you’re riding, you’ll appreciate the revised Pro-Link rear suspension with a new link system that’s less prone to flexing, and the redesigned shock with smoother action. When you’re wrenching, you’ll love the new ease of access to the rear suspension assembly. Removing the shock used to take about 21 minutes, by our watch, but can now be done in about 9 minutes. No more removing the seat, muffler and rear frame.
