2016 Yamaha motocross range
A few enhancements to the engine and chassis in the four-stroke models, including an updated launch control system on the YZ450F for "quicker and smoother race starts"Yamaha has released details on its 2016 motocross tackle, with revisions concentrating on fine-tuning already capable packages.
As always, the two four-strokes – the YZ250F and YZ450F — have garnered the most attention, with both now featuring a 20mm larger front disc brake (up from 250 to 270mm), new pad material, updated shifters ad revised suspension settings. They will be available in two liveries — Team Yamaha Blue or 60th anniversary yellow.
Other changes to the YZ450F are:
- A new launch control system, ideally suited to hard surfaces;
- New intake and cam exhaust profiles to improve the bottom-end and mid-range;
- A reshaped swingarm pivot and updated engine mounts, moving the dimensions more towards the YZ250F; and
- New triple clamps reduce trail with a 25mm (formerly 23mm) fork offset to improve front-end feel.
The YZ250F has a new, lighter forged piston, which together with revised EFI mapping is claimed to improve performance. The engine also has revised piston oil jets, an updated crank, and a new ECU.
The wet weight of the Bridgestone-shod YZ250F remains at 105kg — or just a smidgeon under — and the YZ450F tips the scales at 112kg wet. The YZ450F has Dunlop rubber.
The two-stroke range — YZ250, YZ125 and YZ85 — is unchanged apart from a gold chain and black wheels now adorning the 125.
