Details

    Count on the Yamaha GYTR High Compression Piston Kit to put up a 1.5 to 3 hp increase across your powerband, supplying power that won't disappoint regardless of riding type. An all forged construction, excellent wear, and superior lubricity give the GYTR piston enough strength to push the compression inside your combustion chamber up into the teens for a more efficient and powerful combustion.

    Yamaha understands the pursuit of power, that's why they set up the face of the GYTR high compression piston for additional mods with extra material taken from the valve pockets. This gives the crucial clearance you'll need if you decide to install more aggressive cams. For some models of machine, it’s possible to use this piston with stock gaskets (not included), which makes installation even easier since these piston kits don't need crank rebalancing to function properly.

    A high compression piston has never been easier to install or more optimized for your machine’s performance than Yamaha’s GYTR High Comp Piston. So whether you want a solid base for additional add-ons or just that extra little bit to put you on top, Yamaha’s GYTR High Compression Piston Kit will give you what you need.

    Specs:
  • High compression forged aluminum piston
  • 1.5 to 3 horsepower increase across power band
  • Includes piston, piston rings, wrist pin, and circlips
  • Valve pockets increase piston to valve clearance
  • No crank rebalancing required
  • NOTE: Requires minimum 100 octane racing fuel
  • NOTE: This performance accessory does not meet California standards for off-road recreational vehicle usage regardless of model year.
  • NOTE: Increases engine compression ratio on YFZ450 to 13.0:1 (stock '06~'09 is 11.2:1), on YFZ450R/X to 13.2:1 (stock is 11.4:1)

nothing better than gytr products!

Comments On May 28, 2013:I decided to heavily modify my yz250f motor and this piston was a great choice. you'll need to use race fuel,100 octane min, but if your looking for more power in this motor get an exhaust then upgrade the piston. if you still want more then get some stage 2 cams and a valve spring kit! it'll be one head rippin 250f!
