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

Fit 1999 Honda trx300ex Sporttrax quad. Piston was lighter than the stock Honda part but I used it without issue.****Keep in mind there is a 300ex fourtrax which is different so don't get them mixed up! This is for the Sportrax sport model not the rancher style.***Should fit all 1993-2008, hope this helps!

Made my 2000 Honda Trx 300 ex run better that ever. Rings end gaps were almost all in spec, except for one but no big deal. Overall great product.
