If you love the fast revving nature of your YZ but want to carry more momentum when you’re not on the throttle, pick up a Yamaha GYTR Off-Road Flywheel for your motorcycle.
The GYTR Flywheels are complete assemblies that come precisely tuned to increase inertial mass and give your bike’s power delivery a much smoother roll-on. With the increased weight of the GYTR Flywheel your bike won’t bog down or lug as badly if you happen to short shift. You’ll also be able to keep momentum up at low speeds without having to abuse the throttle in tight corners or more technical sections of your ride. That means you’ll be able to seemingly coast through hectic situations that would otherwise make you stall out.
There’s an old adage that says, "Slow is smooth. Smooth is fast." Find out for yourself how much of a difference smooth power can make to your riding ability with Yamaha’s GYTR Off-Road Flywheel.

NOTE: Flywheels are measured by inertia weights because the effect of the weight differs depending on where it is in relation to the center of the crank. A 4 oz. and 6 oz. weight might have the same effect depending on where they are positioned in relation to the center of the crank. - See more at: https://www.yamahapartsandaccessories.com/product/details/gytr-flywheel#sthash.Avko2Pmy.dpuf
