2014 Yamaha YZ250F Overview

The 2014 Yamaha YZ250F is a cross / motocross motorcycle built around 250 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. 2014 Yamaha YZ250F delivers. The factory-quoted top speed stands at 120 km/h, making it a capable performer in its class. From a practical standpoint, the 2014 YZ250F tips the scales at 103 kg, carries a 6.06-litre fuel tank, offers a seat height of 991 mm and spans a 1,476 mm wheelbase. Scroll down for the complete 2014 Yamaha YZ250F spec sheet covering every technical detail from suspension travel to tyre sizes.

2014 YZ250F - Pros & Cons

Strengths

Factory engineering: The 2014 Yamaha YZ250F represents Yamaha's engineering at the time, with a specification built around real-world usability.

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 991 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
Modest fuel capacity: The 6.06-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 YZ250F 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 YZ250F 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. Hydraulic disc. Hydraulic 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 YZ250F runs KYB Speed-Sensitive System, inverted fork: fully adjustable, 11.8-in travel and KYB Fully adjustable single shock 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 Bilateral Beam frame - 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 103 kg, the YZ250F is light enough to manhandle easily at a standstill - one of the practical advantages of its class.

YZ250F - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2014 Yamaha YZ250F, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained YZ250F 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 on any YZ250F. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. 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 YZ250F 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 YZ250F. 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.
