    Typo in 16.2.3 Next Gen 1 500: The 126-250 is not correct for this class.

      That’s the only typo/misspelling/random capital letter/incorrect punctuation/missed ‘normal’ editorial style item you found??

      Keep looking — it’s like an Easter egg hunt, only easier… 🙂 🙂

    Keep evolving AHMRA. Nice to see a forward thinking organization. Some would rather see it sink than swim! Change as change is needed!

    One small correction for Suzuki: 1987 Suzuki RM125 had a rear drum brake stock and would be Pre-Modern. 1988 was first year rear disc for RM125. The RM250 information listed is correct.
