FULL DESCRIPTION

KTM EXC/EXC-F 70mm Swingarm Extension CNC Alloy Blocks

These swingarm extension blocks are precision-engineered from 6061 T6 aluminum and CNC-machined for superior weldability. They are designed to extend the swingarm by 70mm.

Originally developed for KTM-based sidecars by TAG-Z Motorsports, these blocks are also utilized by dune riders seeking improved stability on high-power bikes and in hill climb applications. Please note that you are purchasing the blocks only, not the swingarm itself.

Key Features:

  • Constructed from durable 6061 T6 aluminum for an optimal balance of strength and weldability.
  • CNC-machined for precise fitment and performance.
  • Designed to add 70mm of length to the swingarm.
  • Suitable for specific KTM EXC and EXC-F PDS swingarms.
  • Will not fit linkage swing arms.

Installation Requirements:

  • This is a weld-in modification. Installation requires cutting the existing swingarm and TIG welding the extension blocks into place.
  • Installation must be performed by a skilled fabricator.
  • Full preheating of both the swingarm and extension blocks is essential for a proper and secure weld.

Important Disclaimer: Installation of these extension blocks is undertaken at your own risk. While instances of successful installation are numerous, responsibility for any damage or failure of the swingarm due to improper installation cannot be accepted.
