Suzuki made a model called RM100 already in the seventies and early eighties, but here's the 21st century version of the small motocrosser.
”This new mid-size motocross model that bridges the gap between mini-class models and full-size 125 and 250 models. The high-revving, liquid-cooled engine has emphasis on low-to-mid rpm power while retaining excellent top-end power.”
The 2003 RM100 was actually a Kawasaki KX100 with yellow plastic as part of the Kawasaki-Suzuki alliance. Other shared models were the DR-Z110 (Kawasaki KLX110), the RM65 (Kawasaki KX65), the DR-Z125 (Kawasaki KLX125), the DR-Z400 (Kawasaki KLX400) and they jointly developed the RM-Z 250/KX-F 250. Suzuki designed the engine and Kawasaki did all the leg work, which explains how it acts nothing like any other Suzuki.
