2016 Yamaha YZ450F - First Look: 2016 Yamaha YZF & YZ Models - Motocross Pictures - Vital MX

Vital MX - Get the scoop on Yamaha's 2016 model range, including some 60th anniversary YZFs and even a new 250 two-stroke enduro bike.


The YZ450F features an all-new Launch Control System (LCS) that utilizes high-precision ECU calculations to optimize power output and provide ideal acceleration out of the gate, especially on hard track surfaces. New intake- and exhaust-cam profiles and timing help boost combustion efficiency and improve the engine’s ease of use in the low- to mid-rpm ranges. And, like the 2016 YZ250F, the YZ450F has an improved clutch boss and shift-stopper arm for smoother clutch engagement feel and more precise shifting action.

Other improvements to the YZ450F for 2016 include revised engine mounts and a reshaped swingarm pivot section on the aluminum frame to improve lateral rigidity. Footpegs are now mounted 5mm lower to help lower the rider’s center of gravity for improved machine balance and control. New triple clamps with a 25mm fork offset help improve front-end feel, and a new shock spring provides an ideal balance between bump absorption and handling performance. The same as on the 2016 YZ250F, new brake pad material and a larger 270mm front brake rotor deliver improved stopping power and control for aggressive corner entries.

The 2016 YZ450F will be available in two color options: Team Yamaha Blue/White and Limited-Edition 60th Anniversary Yellow.

The YZ450F is priced at $8,590 in Team Yamaha Blue/White and $8,690 in Limited-Edition 60th Anniversary Yellow and will be available in dealerships beginning in late June.

New for 2016:

Launch Control System

Launch Control System (LCS) uses high-precision ECU calculations to optimize power output, providing ideal acceleration off the gate, especially on hard track surfaces.

New Cam Profiles

New intake and exhaust cam profiles and timing boost combustion efficiency and improve the engine’s ease of use in the low-to mid-rpm range.

Updated Shifter

Revisions to the clutch boss and shift stopper arm provide smooth clutch engagement feel and more precise shifting action when the gate drops.

Revised Frame

Revised engine mounts and a reshaped swingarm pivot section of the aluminum frame improve lateral rigidity, while 5mm lower footpegs help lower the rider’s center of gravity for improved machine balance and control.

Revised Suspension Settings

New triple clamps reduce trail with a 25mm (formerly 23mm) fork offset, improving front-end feel, while the new shock spring provides an ideal balance between bump absorption and handling performance.

New Front Brake

New 270mm front disc brake (up from 250mm) also features a new brake pad material for exceptional stopping power and control for aggressive corner entries.

Engine:

Updated Cam Timing Specs

New intake/exhaust cam profiles and valve timing increase low- and mid-range torque, resulting in added power and outstandingly controllable performance.

Wraparound Rear Positioned Exhaust Layout

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 piston cooler spray jet eliminates the need for an oil tank, reducing engine weight. The water pump employs a new six-hole impeller with increased seal durability for long-term reliability. The reduced size of the crankcase enabled by this lubrication system design is a major factor in making it possible to mount the 450cc engine on the compact frame to deliver precise and instinctive handling.

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.

Chassis/Suspension

Bilateral Beam Aluminum Frame

A reshaped swing arm pivot area and updated engine mountshighlight updates to the Bilateral Beam frame that features overall dimensions that are roughly the same as the frame of the YZ250F. This gives the YZ450F a compact chassis that provides the most instinctive handling in the 450 motocross class.

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 allows a shorter, lighter subframe and also contributes to mass centralization for lightweight handling feel.

Updated Suspension Settings

Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping features new settings and a new fork off-set, which works with the revisions to provide exceptional balance between handling and bump absorption. The rear KYB® suspension also features settings optimized for ideal damping characteristics to match the new chassis rigidity.

Race-Ready Construction

The large diameter 22mm front axle and beefy top triple clamp provide rigidity for unmatched handling and front-end feel. The handlebar mounts are rubber mounted to improve comfort and reduce handlebar vibration.

New 270mm Front Brake

New 270mm front brake system is a huge 20mm larger than the disc fitted to the 2015 YZ450F and uses an all-new pad material for exceptional stopping power and braking control.

Centralized Fuel Tank

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
