This Kit Fits:  Honda TRX400EX, TRX400X and XR400R.  See our fitment table for exact years.

Honda TRX400EX Piston Kit is a better-than-original 85mm piston kit.  It has been engineered and tested to exceed original equipment standards and performance. The set includes a piston, piston ring set, wristpin, circlips, head and base gaskets, and NGK sparkplug.

The Niche brand piston is cast aluminum and is designed to provide the standard compression of 9.1:1.  The package also contains a high-performance top end gasket kit to help give your engine more reliability and longevity.

All the pieces included are direct replacements parts for easy, hassle-free installation with no modifications or adjustments needed.

Is your TRX400EX experiencing low compression? Low compression can be caused by worn-out piston rings or worn-out gaskets not sealing the combustion chamber properly. Restore your engine to its original power with our Honda TRX400EX Piston Kit. 

Why our piston kit? We’re proud to provide excellent customer service, fast shipping, knowledgeable staff, and quality parts at reasonable prices.
