While testing out at Glen Helen on Thursday, the MXA Wrecking Crew saw a 2023 KTM 250SX two-stroke absolutely shredding around the National track. Once again, it’s Marvin Musquin out testing with the KTM R&D department, this time riding a pre-production
250 two-stroke and going extremely fast. Enjoy this RAW video we put together quickly after a day’s work at “the office.”
