Eligibility for Pre 90
« on: November 18, 2013, 05:00:34 pm »
[color=orangeIn the MOMS for the Pre 90 classes in says "Acceptable for Pre 90 class are machines and components built up to and including the 1989 model. The only exception to this rule is where the model remains unaltered after this date."


[/color]What I would like to know is what changes were made to the KTM 500s after 1989. eg 1990, 1991 etc models.
