NICHE CYLINDER
- ATV engines come with either one or two cylinders
- Displacements typically measuring between 100cc and 800cc
- It's important to note that safely riding an ATV requires a certain amount of body weight and physical strength
- Disaster can strike, for example, when a young rider uses an overpowered or a larger ATV
NICHE PISTON
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
NICHE GASKET
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.
Some Types of Gaskets:
- Head gaskets create a seal between the engine block and cylinder head. This seal establishes a proper compression and prevents fluid leaks into the cylinders
- Base gaskets create a seal between the top-end of your engine and the engine cases. Stop pesky engine oil leaks before they cause permanent damage to your engine.
- The valve cover is sealed to the upper section of the engine cylinder head by a valve cover gasket. As it passes around the camshafts, rockers, and valves, the gasket stops engine oil from seeping out.

Good top end kit for the money. Parts seemed like they were of decent quality. My only complaint is the lack of alignment dowels and the rings aren’t marked well. You must reuse the old dowels. Not a huge deal. This kit went together easy and runs great so far. I would buy it again.

I repair Atvs/Utvs and I must say, this is the 3rd time I use their products. I had one small issue with a ring prematurely breaking while I was installing them. I emailed tech support and in no time they sent me a new piston and set of rings. I like their products as they are very affordable and they do stand behind them. Bravo NICHE Industries keep making affordable quality parts and thanks for standing behind them.

Piston doesn't fit the 2008 700xp. The connecting rod opening is too narrow. Reused my old pistons with these parts. The seller agreed to a reasonable solution to this problem
