Yamaha Announces 2017 Motocross Models
Corporation, U.S.A., is pleased to introduce its
championship-winning and bLU cRU-inspired
2017 Motocross model lineup, which includes the YZ250F and YZ450F
four-stroke machines, along with the iconic YZ250, YZ125, and YZ85
For 2017, the YZ250F incorporates many changes including revised intake geometry for additional downdraft effect, which is matched to a shorter intake funnel in the airbox for improved top-end power. Inside the head, more aggressive camshaft profiles and valve springs boost output further, while larger valve seats ensure excellent sealing and reliability.
Also, the 2017 YZ250F's entire diecast crankcase features a new heat-treating process that was developed to increase strength. Inside, a new nickel-chromoly steel connecting rod offers additional durability to handle the increased power output.
New gear dogs, revised gear-tooth designs, and a host of smaller changes to the transmission on the 2017 YZ250F provide smoother shifting, as well as a stronger overall powertrain for improved durability.
Revised engine mounts and a reshaped swingarm pivot section on the 2017 YZ250F's aluminum frame improve lateral rigidity, while 5mm lower footpegs help lower the rider's center of gravity for improved machine balance and control. Also, suspension settings have been revised at both the front and rear to match the chassis updates.
In addition, a redesigned air cleaner cover on the 2017 YZ250F helps prevent contact with the quick-release quarter-turn DzusÂ® air box fasteners and provides tool-less access to the air filter, which is positioned at the front of the bike to avoid roost from the rear wheel.
The 2017 YZ450F receives updated rear brake-rotor material providing better heat resistance, durability, and braking feel. And, as on the 2017 YZ250F, the YZ450F features a redesigned air cleaner cover for 2017 that helps prevent contact with the quick-release quarter-turn DzusÂ® air box fasteners and provides tool-less access to the air filter that's positioned at the front of the bike to avoid roost from the rear wheel.
The YZ250, YZ125, and YZ85--all three of which are powered by legendary Yamaha liquid-cooled, reed-valve inducted, two-stroke engines--are back again for 2017.
For 2017, the YZ250 has a new 270mm front brake rotor (up from 250mm) and new front brake-pad material for exceptional stopping power and control to make more aggressive corner entries.
The YZ125, with its agility and power, is the perfect transition from the YZ85 to Yamaha's YZ250F. For 2017, the YZ125 is also equipped with a new 270mm front brake rotor and new front brake-pad material for improved stopping power and control.
Each 2017 YZ will be available in Team Yamaha Blue. The YZ450F and YZ250F will also be available in White/Red as a second model color. The YZ450F will retail for $8,699, the YZ250F is priced at $7,699, and both bikes will be available in Yamaha dealerships beginning in June. The YZ250 carries a MSRP of $7,399, the YZ125 is priced at $6,499, and the YZ85 will retail for $4,099. All three two-stroke models will be available in Yamaha dealerships beginning in August.
