A Winner Right Out of the Gate - the 2016 Yamaha YZ250F
This week, we're featuring one of the pre-owned gems from the lot at Surdyke Yamaha at the Lake of the Ozarks - the impressive 2016 Yamaha YZ25OF! A winner right out of the gate (like all of the dirt bikes for sale at the Lake of the Ozarks we carry, both new and used), this Motocross and Supercross Champion could be the perfect bike for you.
Top Features
- Innovative Engine, Updated for More Top-End Power: Liquid-cooled, DOHC 4-valve, fuel-injected engine with the same forward-positioned, straight intake, rear-inclined cylinder and rear positioned exhaust layout as the YZ450F – now with further optimized crank balance and even more advanced piston technology between the cases.
- Advanced Fuel Injection: The four-titanium-valve cylinder head is matched to a battery-less fuel injection system that provides optimized power at any rpm. The fuel injection system instantly adjusts the air/fuel mixtures depending on altitude and temperature, for a hesitation-free engine that delivers no matter the conditions.
- Bilateral Beam Aluminum Frame: The aluminum Bilateral Beam frame offers a superb rigidity balance and provides unmatched lightweight handling, with updated suspension settings for smoother damping feel.
- Wraparound Rear Positioned Exhaust Layout: The exhaust pipe has an innovative layout, circling the cylinder, giving the exhaust pipe proper length for an excellent exhaust pulse effect. At the same time, the exhaust pipe has three different diameters throughout the exhaust tract, bringing out excellent power characteristics. This layout allows the silencer to be moved forward, behind the side panel, making it closer to the middle of the bike for centralized mass for superior handling.
- Mass-Centralized Ergonomics: The layout of the seat, fuel tank, air box, and wrap-around exhaust system moves the bike’s mass towards the center for exceptional handling. The front intake layout with large air filter element adds the benefit of reduced air filter maintenance due to its positioning away from dirt roost from the rear wheel.
- New 270mm Front Brake: Beefy 270mm front disc brake coupled with new pad material offers outstanding braking power and performance, with exceptional controllability.
- GYTR® Power Tuner Ready: Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons, as well as monitor engine diagnostic codes.
- Innovative Engine Design: A liquid-cooled, DOHC 4-valve, fuel-injected engine with the same forward-positioned straight intake, rear-inclined cylinder and rear positioned exhaust layout as the YZ450F. The engine, with its straight and symmetrical intake and exhaust ports and compact, high compression combustion chamber, delivers outstanding engine character in the high speed range.
- Advanced Fuel Injection: The adjustable fuel injection system uses a 44mm throttle body fed by a high-pressure battery-less electric fuel pump. This ensures optimum fuel atomization and air/fuel calibration for excellent rideability in a wide range of riding conditions. The system controls the volume of fuel injected and the ignition timing based on engine rpm and throttle opening, providing hesitation-free response and controllability.
- New Piston, Rod and Crankshaft Balance: The all-new, flat-top designed forged piston now features a bridge-box design for additional strength, yet is even lighter for 2016. The piston, rings and new DLC-coated piston pin, along with the offset cylinder configuration, all reduce friction loss and contribute to quick response, while the updated oil cooling jet ensures high rpm reliability. As before, the YZ250F’s intake/exhaust ports, cam profiles, ECU, carburized crank and newly optimized balance ratios for the crank and balancer all work together to create the YZ250F’s outstanding engine character with more power in the high-rpm range.
- Wraparound Rear Positioned Exhaust Layout: As with the YZ450F, an innovative exhaust pipe design is adopted to increase mass centralization and improve power development characteristics. This layout moves the rear end of the exhaust pipe farther forward and enables a muffler position close to the center of the mass. Adjustments are made in the pipe diameter in its various sections resulting in excellent exhaust pulse effect that contributes to high rpm power output, while a new muffler bracket reduces weight.
- Compact Engine Layout: The compact wet sump lubrication system with new piston cooler spray jet maintains excellent engine durability and eliminates the need for an oil tank, which lowers engine weight. This creates a more compact engine that contributes to mass centralization and unmatched handling.
- Updated Clutch: The clutch and shift mechanisms are updated for 2016 to reduce drive-force loss during gear changes and produce smoother shift action under the heavy demands of motocross racing.
- GYTR® Power Tuner Ready: Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons, as well as monitor engine diagnostic codes.
- Mass-Centralized Exhaust System: The aluminum muffler is positioned closer to the machine’s center of gravity as it is almost completely hidden by the side number plate. The layout contributes to centralized mass for a lightweight handling feeling.
- Updated Suspension Settings: Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping features revised valving for improved suspension feel and balance in each section of a corner, from entrance to exit. The KYB® rear shock also features settings optimized for ideal damping characteristics.
- Race-Ready Construction: The large diameter 22mm front axle and beefy top triple clamp provide rigidity for unmatched handling and front-end feel. The four-position adjustable handlebar mounts are rubber mounted to improve comfort and reduce handlebar vibration.
- New 270mm Front Brake: A new 270mm front brake disc is the same system fitted to the 2016 YZ450F and is a huge 20mm larger than the disc fitted to the 2015 model, using an all-new pad material for exceptional stopping power and braking control.
- Compact Fuel Tank and Air Box: The Yamaha-exclusive fuel tank and air cleaner box layout positions the fuel tank mass closer to the center of the bike which improves handling feel. Furthermore, the air box is positioned in front, away from the dirt kicked up from the rear wheel and can be accessed without tools for easy serviceability of the air cleaner.
- Embedded Graphics: Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.
