A lightweight 125 cc two-stroke enduro with a kick start, a carburettor and a fully adjustable Ohlins rear shock. Reviewers praised its low weight, agile handling and strong low and midrange power, while noting it needs more gear changes than a 250. The model was a cheaper alternative to the 250 with the same chassis character.
