One of the lesser known CDI units for the XR650R is the Procom part number PE-C-MH650-A. They claim the following:

  • Improved Timing curves
  • Higher Rev Limit
  • Overrides for full performance at all times (who knows what that means)
  • Increased Spark Energy
  • Improved Throttle Response
  • Easier Starting
  • Plug-in Module Replacement (just means it’s plug-n-play)

Another option – and potentially cheaper is swapping an XR400R CDI into the XR650R.

There is also a Big Gun CDI for the XR650R.
