Always love these types of stories: the random nuances of MX history that are probably insignificant to casual enthusiasts but are fascinating to moto-nerds like me.
TRULY UNBREAKABLE RECORDS
Never realized the bit about Steve Lamson being the only 125cc rider to outright win a moto at the MXdN. My moto knowledge starts to get pretty fuzzy for anything pre-1990, so I always thought Johnny O had won at least one moto at Maggiora in '86 since that performance is discussed so often.
Thanks DC! Keep 'em coming!
