MXA’S FULL-RACE KTM 250SXF AMA NATIONAL BUILD

MXA’s 2025 KTM 250SXF Factory Edition was turned into a Pro AMA National race bike for test rider Ezra Lewis, to pilot at the Hangtown National. This build was a collaboration between REP’s Mark Johnson and Twisted Development’s Jamie Ellis. Mark pens his “Suspension Simplified” column every month, and Jamie is the author of our “Twisted Logic” page. Mark and Jamie are masterminds in their field sof work, and both have previously been employed by factory teams before they branched out to open up their own businesses.

For the last year, Ezra Lewis has been working at REP, and Mark encouraged Ezra to line up for Hangtown, and he helped him build up our KTM 250SXF Factory Edition to do it.
