    The vertex piston oil ring was pretty cheesy

    Not to sure how long this thing will last . Over all every thing was allright but the oil ring was pretty cheap . You would think they would give a better oil ring thats the only thing i could see going wrong .the stock pistons oil ring was 3 times stronger. Will let u know how it holds up thanks

    Tons of Compression

    I didn't realize how much power my engine had lost until I installed this cylinder kit a few weeks ago. My DRZ is like a new bike. It sounds like a throaty 4 stroke again and is much more responsive. The kit was easy to install and reasonably priced. We'll see how it holds up long term but it looked and felt like a quality part while I was installing it.

    GYTR Head

    Expensive engine mod but if you are serious about powering up your YZ grab this and get to the front. Need to use VP u4.4 but you should already be using that if your racing at all . Be sure to set the new mapping to the ECU !

    Put this on my bike along with the Dr. D radiator lowering kit and the two together made my bike handling a lot better than it ever did before. Recommend both kits for anyone with a 10-13 yz450
