Genuine Yamaha Technology Racing Accessories for 2010 YZ450F

New stuff from Genuine Yamaha Technology Racing for the 2010 YZ450F:

-GYTR® Exhaust System ($899.95)

Yamaha says its Exhaust System for the 2010 YZ450F was developed through hours of dyno and track testing to produce the best exhaust system. It features include an aluminum muffler shell, stainless-steel tubing, and magnesium end cap. It's 98-dBA compliant, and completely rebuildable.

-GYTR® High Flow Air Filter ($14.95)

Two separate layers of foam provide optimized filtration with maximum airflow for this GYTR filter, and we all know that more airflow means more performance. It's completely washable and reusable, too.

-GYTR® Ported Cylinder Head Assembly ($1,995.95)
This head comes fully assembled and ready to install - no costly core charges or deposits, or exchange programs that can add to downtime. CNC milling ensures that every head is ported to the maximized design eliminating variances that hand porting can produce. Developed on the flow bench in conjunction with dyno and track testing to ensure the ultimate in performance and durability. Includes GYTR® Performance Camshaft Kit, and (for YZ250F application) GYTR Valve Spring Kit. Also includes stock valvetrain, and cam gears for durability and easy maintenance. These are the same head assemblies used by the Yamaha Factory SX/MX and ATV Race Teams.

-GYTR® Power Tuner ($279.95)

This easy-to-use plug-in fuel-injection and ignition-tuning tool from Genuine Yamaha Technology Racing allows riders to quickly adjust the fuel and ignition maps to suit riding conditions and rider preference. The tuner allows for nine adjustment points for both the fuel and the ignition maps. The user can monitor the data from various sensors on the bike, as well as adjust idle timing and see the engine running time. The power source is just two AA batteries, thus no laptop or time-consuming downloads are necessary. It does not have to be plugged into the bike to create maps, either. Its compact design means it can fit in the palm of your hand or pocket, and the maps can be shared from tuner to tuner.
