Give your 125cc two-stroke new power and reliability with the Vertex 53.95 mm Piston with Dual Piston Rings – the high-performance piston that fits perfectly on KTM SX 125 (2001 and newer), KTM EXC 125 (2007-2016), Husqvarna TC 125 (2014 and newer), and Husqvarna TE 125 (2014-2016)!

Vertex has been a leading brand in the two-stroke industry for years, delivering race-grade pistons. This 53.95 mm piston (standard oversize) is crafted from high-quality forged aluminum with a special coating for optimal heat dissipation and minimal wear. The dual piston rings provide improved sealing, higher compression, and a longer service life – ideal for intense motocross use, training, or competitions.

This piston includes the proper rings, wrist pins, and clips, and fits 100% plug-and-play into the original cylinder (or after a light honing). It delivers more power, sharper throttle response, and cleaner combustion compared to a worn factory piston. Whether you’re completing a new big-bore build or simply rebuilding your engine, this Vertex piston will restore your KTM or Husqvarna to top condition.
