The ultimate YZ250/YZ250X Piston Kit 1999-2025
The ultimate YZ250/YZ250X Piston Kit 1999-2025
Looking for the best yz250 piston money can buy? Get the EXACT technology we used in our main event placing yz250 two stroke ridden by Jared Lesher.
In our development program for the yz250 over the years, we have encountered every weak link you can imagine - and the std piston under hard use is prone to shattering and causing total engine loss.
Have a stock bike, no problem! Excellent stock replacment option.
Have a mod bike, even better!
Features Include:
- This piston uses a special forging unique to our durability and performance needs
- Ring pin pinned on centerline/6 oclock position for increased durability and ability to improve the B transfer ports not allowed by stock ring pin location
- Single Ring for reduced friction, increased power
- Special size for hard pro usage
- Teflon coated skirt for last line of protection
- Special dome and ring land, underside coataing for maximum durability
- Saves nearly 10 grams from OEM for reduced vibration and improved rpm ability
- Signature series Jared Leshar laser etched in the dome
- 412 in the coating on intake side - don't worry - helps retain oil in those areas.
Support the privateer effort of Jared with every purchase!
