2014 Yamaha YZ250 Overview

For 2014, Yamaha offers the YZ250 as a cross / motocross motorcycle with 249 cc on tap. The 2014 Yamaha YZ250 is built around a Single cylinder, two-stroke engine, a compression ratio of 8.9:1. Internally, bore and stroke are 66.4 x 72 mm. Out on the road, the YZ250 delivers. Flat out, it's quoted at 120 km/h. In everyday use, the 2014 YZ250 tips the scales at 103 kg, carries a 7.95-litre fuel tank, offers a seat height of 993 mm and spans a 1,481 mm wheelbase. That's roughly 6.6 kg lighter than the average cross / motocross motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2014 Yamaha YZ250 spec sheet below.

2014 Yamaha YZ250 compared with other bikes in the Cross / motocross category

Measured against other bikes in the Cross / motocross category in our database (up to 200 models, one entry per model), the 2014 Yamaha YZ250 comes out as follows.

With 993 mm, the YZ250 has the 8th tallest seat height of 200 bikes in the Cross / motocross category, 10% above the category average of 902 mm.
Wet weight of 103 kg is lighter than that of 86 of the other 128 bikes in the Cross / motocross category.
Narrowing the field to the 97 models within five model years of it, the seat height of 993 mm is taller than that of 93 of the other 96.

Versus the 2013 model

The figures we track are unchanged from the 2013 model: wet weight, displacement and seat height all match.

2014 YZ250 - Pros & Cons

Strengths

Strong front braking: The single disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.

Considerations

Carburetor fuelling: Carburetion is more hands-on than fuel injection - plan on periodic jetting and cleaning as part of routine ownership.
Tall seat height: A 993 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
Modest fuel capacity: A 7.95-litre tank keeps things light but means budgeting for more frequent fuel stops on any longer ride.
Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.

Wear Points & Servicing Notes

Carburetor maintenance

Being carbureted, the YZ250 is more sensitive to stale fuel and altitude changes than a fuel-injected bike - a carb clean and rejet restores crisp throttle response after any extended lay-up.

Brake disc and pad wear

Single disc with hydraulic disc up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Suspension condition on used examples

Suspension duties are handled by Speed-Sensitive System inverted fork up front and Fully adjustable single shock, 12.4-in travel at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Chain final drive on the YZ250 means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.

Low-speed handling

The YZ250's 103 kg kerb weight makes low-speed control noticeably less effort than on a heavier machine.

YZ250 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 2014 Yamaha YZ250 with its 249 cc cross / motocross should cover the same ground every time: service history, drivetrain condition, and any oil seepage around the casings. 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 12 years old, this cross / motocross is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept YZ250 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for the YZ250's 249 cc single cylinder, two-stroke - keep to the manufacturer's interval rather than stretching it. With an 8.9:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.

Carburetor upkeep

A YZ250 that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.
