  • Wiseco Piston Kit

    LARRY in FL

    2 stroke rebuild. great option

    This is the third time i have used this piston on a rebuild. None of these have failed to perform. Each was replaced before it was needed. Great choice for replacing the OEM product.

  • Wiseco Piston Wristpin Bearing

    BERNARDO in Baja California

    Wiseco quality

    I replace this bearing Everytime I change the top end or Piston ring of my yz 125. Wiseco should include this bearing in the Piston kit. Never had any problems.

  • Wiseco Steel Intake Valve Kit

    Tim in CO

    Quality Steel valves, Yes please!

    This kit has everything you need to get the titanium valves out of your bike. If you need to replace the valves anyway there is no reason not to do this kit instead of oem valves. Wiseco makes great products and they will last longer than the bottom end if done right the first time.

  • Wiseco Racer's Elite Piston Kit

    Amy in UT

    Hole was too small for wrist pin

    Bought one for a YZ 125 and the wrist pin would in no way shape or form go into piston, the stock wrist pin would not go in either and the Wiseco wrist pin fit in the stock piston so the piston itself was bad (wrist pin hole too small), sent it back and took forever to get confirmed it was bad and I had not messed it up and account credited. I ran one previous in a KX 100 that had head milled and PC pipe, the bike was finicky before but was even more so after, would only run on VP 110 and Redline oil and could never get jetting correct, where as it ran good on any race fuel and any oil with general jetting adjustments before. Maybe you try it but be prepared to switch back to standard. Agree with others that there needs to be more quality control (to be called Racer's Elite)
