Wiseco Pro-Lite 2-Stroke Piston Wiseco Pro-Lite 2-Stroke Piston Dave - NM Great product "Put this in my KX500 that was a bit tired. Installation was smooth. Be sure to put the piston rings on the spring notches as your putting the cylinder back on. Went on smooth, gaskets fit fine and where packed nice. For my break in.. 1. Fresh Oil (not synthetic) 2. Warmed engine up at idle to operating temp. 3. Let cool down until engine is completely cold 4. Repeat step 2 and 3 5. Took it on an easy 20min ride at 50% through 3rd gear. 6. Let it cool down and recheck all torque specs 7. Next day compression test then took it out riding, just warmed it up and kept it around 75% riding regular dirt roads for 30min or so. Stopped and ate a snack while it cooled down.... then ripped it for 4 hours like I stole it. Hyuuuuuge improvement in response, my bottom end snapped harder and when that powerband hits in 4th and 5th on my 500.. hold the F on. Great product and it's why I run Wiseco pistons."

Engine Parts for Dirt Bikes

Staying on top of general maintenance goes a long way towards the life of your 2-stroke or 4-stroke dirt bike engine. Eventually though, engine parts break down or seize up and need replacing. MotoSport carries what you need for the simple jobs like oil changes or the major overhauls like a complete engine rebuild on your dirt bike.

Don't let a slipping clutch or blown motor ruin your planned ride day. We stock the top names in aftermarket clutches like Rekluse and Hinson or stick with OEM, if you prefer. Replace the blown motor with a piston kit from Wiseco, Vertex or Wrench Rabbit among other popular brands. Smashed radiator? We'll get you back riding in no time.

First things first, extend the life of the motor by keeping up on oil and filter changes. We've got gaskets to take care of that eventual leak, too. Find all the necessary Motocross engine parts you need at MotoSport. We'll ship it fast so you won't miss race day or that trail ride with friends.
