The VERTEX cast piston is designed for the KTM 125 SX from the entire model year range 1994 to 2000. As a component for the upper engine area, it combines a cast piston design with the specified dimensional data for the appropriate selection and assignment.

Design and technical data

• Material: aluminum
• Piston type: cast
• Piston compression: standard
• Diameter Ø: 54.20 mm
• Letter oversize: B
• Oversize: +0.01
• Bore diameter: 54.25mm
• Stroke: 2T

The combination of the diameter of 54.20 mm, the bore diameter of 54.25 mm and the B marking supports targeted selection within the intended engine tuning. The standard compression assigns the piston to a near-series compression version.

Vehicle assignment

The piston fits the KTM 125 SX, built in 1994, 1995, 1996, 1997, 1998, 1999 and 2000. The assignment refers to this entire year range.

Selection note

Before ordering, the existing cylinder bore and dimensions should be compared with the technical data of the piston. The decisive factors are the diameter Ø of 54.20 mm, the bore diameter of 54.25 mm and the oversize +0.01.
