Description

MK1003421 NICHE provides Powersports replacement parts. Some of the NICHE product categories include cylinders, brake pads, axles, off-road mirrors, and drive chains. NICHE parts are here for when you need them the most. An ATV piston is a component of engines, pumps, and gas compressors. It is located in a cylinder and is made gas-tight by piston rings. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft through a piston rod and or connecting rod Piston Anatomy A piston is a cylindrical engine component that slides back and forth in the cylinder bore by forces produced during the combustion process. The piston acts as a movable end of the combustion chamber. The stationary end of the combustion chamber is the cylinder head. Piston Components ATV Piston components include the piston head, piston pin bore, piston pin, skirt, ring grooves, ring lands, and piston rings. The piston head is the top surface of the piston which is subjected to tremendous forces and heat during normal engine operation A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

  • Working good 2013 rzr 800s
Only have around 3 hrs on it so far but it's working as it should.

  • Parts NOT CORRECT SIZE.
The media could not be loaded. Could not use pistons. Pistons are the wrong style for the Kit. In the video I am filling up the coolant. And you can see steam coming off the exhaust. But the pistons are right here on my bench, had to make use of the old pistons.

  • Nice, complete kit
Seems like a very nice, complete kit. I do wish that the piston rings had markings on them showing install direction and position. Looks good otherwise.

  • Ended up buying oem
Had installed by Polaris dealer who let me use these parts and ended up having excessive crank case pressure getting past the pistons. Ended up using oem parts and building a second time
