KTM 125 EXC [2001-2017] - cast piston - solid carbide cylinder head

VERTEX cast piston for the KTM 125 EXC

The cast VERTEX piston is designed for the KTM 125 EXC from the 2001-2017 model year range. With its aluminum material and standard piston compression, it is suitable as a precisely defined component for the 2T engine. The design with a piston ring supports a clear coordination of the relevant piston data.

Design and selection

The combination of 53.94 mm piston diameter, 54.00 mm bore diameter, oversized letter A and the STD marking makes it easier to compare with the existing engine data. Before selection, these dimensions and the specified standard compression should be compared with the intended engine tuning.

Important note on use

The piston is designed for tuned cylinder heads. Use with an OEM cylinder head is expressly not intended. This requirement must be taken into account when selecting and tuning the engine.
