New for the 2005 Yamaha WR250F:

• New combustion chamber shape and other head modifications, along with revised carburetion and ignition settings, produce more power and instantaneous delivery.
• A 10mm-lower and slimmer seat, narrower shrouds and fuel tank increase rider maneuverability for easier handling.
• New, 48mm fork tubes provide even better handling and comfort. New fork protectors provide greater tube coverage.
• Aluminum Renthal handlebar reduces weight, is more durable and looks cool too.
• New, shorter front brake routing gives excellent lever feel and eases brake maintenance.
• New, aluminum muffler is light and stylish.
• New front wheel collar makes front wheel removal quick and easy.
• Lighter rear sprocket for less un-sprung weight.
• Left side cover now has a grab handle for added convenience.
• Light-weight front and rear calipers with aluminum pistons and revised front master cylinder, combined with 250mm fully floating front and 245mm rear disc, deliver strong stopping power with progressive feel.
