Do you have a question about the Kawasaki KX450F - DATASHEET 2011 and is the answer not in the manual?
High-performance digital fuel injection system for improved low-end response and smooth power delivery.
Revised silencer internals meet strict noise regulations, ensuring compliance with 2m-max noise standards.
Allows for precise rear suspension tuning with longer stroke and adjustable damping for improved traction.
High-performance piston design contributes to improved performance and lighter, stronger piston.
Changes to the shift mechanism provide a firmer feeling when gears engage.
Lightweight ECU operates without a battery, eliminating unnecessary weight and simplifying starting.
Revised ECU programme and ignition circuit improve low-rpm response and lengthen spark duration.
Pinched cut-outs in silencer chambers direct exhaust gases to reduce noise.
Simple and hassle-free use: ECU mounts behind number plate, connects via USB to PC for adjustments.
Seven preset settings, 6 hours of data logging, and choice of 2D or 3D display.
Revised rigidity balance results in a frame with moderate lateral flex for lighter turning.
Larger diameter front axle collars increase rigidity, contributing to a more planted front wheel feel.
Longer suspension stroke and precise tuning allow for improved rear wheel traction.
Slim aluminium perimeter frame with forged, extruded, and cast parts, tuned for race-experienced riders.
Revisions improve turning, rear wheel traction, front wheel feel, and cornering accuracy.
Air-Oil-Separate fork for stable damping, low-friction seals, and lighter internals.
DLC coating reduces sliding friction; Kashima Coat enhances smoothness at stroke start.
Magneto rotors with different inertias available.
Handlebar holders, rear sprockets, and brake rotors available.
Different spring rates available for front forks and rear shocks.
Optional indicator lamp warns of problems with the FI system.
