Not the most attractive of the RM125s, this was the last year for the aircooled engine and the last year before the addition of the Full Floater suspension. Suzuki had won every 125 Motocross World Championship up till that point (4 of them), the 125 class had only started in 1975. Suzuki continued its winning streak for another 5 years, losing to Cagiva in 1985.
Which year was the best looking? My vote goes to the RM125A.
