2011 Kawasaki KX250F Overview

The 2011 Kawasaki KX250F is a cross / motocross motorcycle built around 249 cc of displacement. Under the tank sits a Single cylinder, four-stroke engine running DOHC valve actuation, a compression ratio of 13.5:1. The bore and stroke measures 77 x 53.6 mm. From a practical standpoint, the 2011 KX250F tips the scales at 105.6 kg, carries a 7.19-litre fuel tank, offers a seat height of 945 mm and spans a 1,476 mm wheelbase.

2011 Kawasaki KX250F compared with other bikes in the Cross / motocross category

Here is how the 2011 Kawasaki KX250F stacks up against other bikes in the Cross / motocross category in our database. Each model counts once, using the model year closest to this one, and the comparison covers up to 200 models.

Wet weight of 105.6 kg is lighter than that of 77 of the other 128 bikes in the Cross / motocross category.
Only 86 of the other 199 bikes in the Cross / motocross category have a taller seat height than the 945 mm of the KX250F.
Narrowing the field to the 66 models within five model years of it, the wet weight of 105.6 kg is lighter than that of 30 of the other 65.

Versus the 2010 model

Compared with the 2010 model, seat height was lowered from 955 mm to 945 mm (-10 mm). Wet weight and displacement are unchanged.

2011 KX250F - Pros & Cons

Strengths

Strong front braking: The single disc front brake gives excellent stopping power and responds well to aftermarket braided lines.

Considerations

Carburetor fuelling: Carbureted engines need occasional jetting attention and can be reluctant in cold weather or at altitude compared to modern fuel-injected alternatives.
Tall seat height: The 945 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
Modest fuel capacity: The 7.19-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.

Wear Points & Servicing Notes

Carburetor maintenance

The KX250F uses carburetion rather than fuel injection, which means jetting is altitude- and temperature-sensitive and benefits from a clean-and-rejet after extended storage or an exhaust change.

Valve clearance checks

DOHC valve actuation on the KX250F means clearances should be checked at the manufacturer's specified interval - they can tighten as mileage accumulates, and a light top-end tick is usually the first sign.

Brake disc and pad wear

The single disc front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the KX250F runs 47mm inverted Showa SFF telescopic fork with spring preload adjustability and 22 position compression and 20 position rebound damping adjustability/ 12.4 in and Uni-Trak linkage system and Showa shock with 19 position low-speed and stepless high-speed compression damping, 22 position rebound damping and fully adjustable spring preload at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Final drive maintenance

Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.

Frame & chassis check

The frame is Aluminum perimeter - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

Low-speed handling

At just 105.6 kg, the KX250F is light enough to manhandle easily at a standstill - one of the practical advantages of its class.

KX250F - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2011 Kawasaki KX250F with its 249 cc cross / motocross, start with the basics: check the service book for oil change frequency, inspect the drivetrain for wear, and look for oil seepage around the engine casings and rocker covers. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 15 years old, this cross / motocross is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. A cold start test is invaluable - a well-maintained KX250F should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task for the KX250F's 249 cc single cylinder, four-stroke. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. With a 13.5:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Always use the correct viscosity grade as specified in the owner's manual.

Carburetor upkeep

Keep the carburetors clean and free of deposits. If the KX250F has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.

Valve clearance service

Check that valve clearances have been adjusted at the correct intervals on any used KX250F. A bike with clearances out of spec doesn't always feel obviously wrong - but tight clearances accelerate valve seat wear. Ask for service documentation proving it's been done.
