§ 02 / About this part
What it is
Vertex piston kit Ø56.00 D to fit the KTM SX 144, model years 2007–2008, and KTM SX 150, model years 2009–2015.
This D-sized piston is intended for small-bore cylinders that have seen heavy use and require the largest oversize to maintain compression. It sits in the top-end and is a critical service item for high-revving engines. Frequent replacement prevents the piston from rocking in the bore, which can lead to catastrophic failure. The kit includes the rings, gudgeon pin, and circlips. Measure your cylinder carefully to ensure this 56mm D-fitment provides the correct clearance. Always fit a new small-end bearing when installing a fresh piston kit to ensure top-end reliability.
