Yamaha YZ250 Vs. YZ250F: Which Dirt Bike Is Suitable For Me?
The YZ250 dirt bike is two-stroke, whereas the YZ250F is four-stroke hence the “F” in its name. However, they ride substantially differently due to differences in engine and chassis. Here is an in-depth comparison of both.
1. On-Track Performance
The YZ250 and YZ250F have much to offer regarding on-track performance. Besides, the YZ250 has a better power-to-weight ratio, which accelerates and tops out faster than the YZ250F.
On the other hand, the YZ250F boasts a more sophisticated suspension system and a larger fuel tank, which can be useful for longer races.
2. Engine
The YZ250 and YZ250F are powered by a 250cc liquid-cooled single-cylinder engine. But the YZ250F features a fuel-injected engine, while the YZ250 has a carbureted engine.
Moreover, the YZ250F’s fuel-injection technology can give more constant power, especially in cold or changing weather conditions.
3. Power
Both versions have a similar power output, ranging between 38 and 49 horsepower depending on the year model. The YZ250F’s fuel-injected engine can provide power more reliably and effectively.
Because the power is smoother and more predictable, the YZ250F allows you to ride faster for longer periods. Furthermore, it does not have as much vibration that busts your hands as the YZ250 does.
4. Suspension
The YZ250 and YZ250F have upside-down forks and a rear shock. Still, the YZ250F’s suspension is more advanced and adjustable. That allows the riders to fine-tune the suspension settings to their preferences and terrain conditions.
5. Weight
The Yamaha YZ250 used to be substantially lighter due to fewer moving parts. But YZ250F technology has advanced so far that they’re no longer much heavier.
However, because of the additional moving engine mass and being more top-heavy, the YZ250F will feel slightly heavier while riding.
6. Off-Road Capabilities
The YZ250 and YZ250F are both capable off-road motorcycles, but they differ slightly in terms of suspension and ground clearance. So the suspension setup of the YZ250 is simpler, with conventional forks and a single shock absorber in the back.
On the other hand, the YZ250F boasts a sophisticated suspension system that includes upside-down forks and a linkage-type shock absorber in the rear. This means the YZ250F has greater off-road handling and stability.
7. Acceleration
The YZ250F has somewhat superior acceleration thanks to its fuel-injected engine and 5-speed transmission, although both models have excellent motocross bike acceleration. Both types use the same hydraulic disc brake system with a floating rotor.
8. Maintenance And Reliability
The YZ250 and YZ250F are relatively low-maintenance motorcycles in terms of maintenance and reliability. But the YZ250F requires more regular oil changes and valve adjustments than the YZ250. As a result, the YZ250 is more reliable than the YZ250F, but its two-stroke engine has a shorter lifespan.
9. Price And Value
The YZ250 and YZ250F are both reasonably priced. However, the YZ250F costs more in the long term due to more regular oil changes and valve adjustments.
10. Cooling System
The YZ250 and YZ250F sport a liquid-cooling system that dissipates heat from the engine more efficiently than an air-cooled system.
11. Tyre
Both versions are commonly outfitted with Dunlop MX3S tires. It’s a high-performance motocross tire made for medium to hard-packed terrain.
12. Wheelbase Size
Both models have a 58.5-inch wheelbase, but the YZ250F has more modern suspension technology allowing it to handle rugged terrain better.
