Suzuki RM100
1976—2003

I have tried to tell the RM 100 model history on this page as I know it. This page is still under construction. I would be grateful of any contributions — sales brochures, magazine ads, magazine articles, pictures, specs, facts, corrections etc. Please scan the material in JPEG format (large enough that all the details are visible) and send them to me. Please tell me the source and the publication date if possible. If you send me pictures of your own bike, please follow these instructions.

Apparently the first generation of the Suzuki RM100 motocross bike was presented already in the mid-seventies. I have found very little information of the early models.

2003 Suzuki year code: K3

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. 2007 saw Suzuki's own RM-Z250, which has garnered critical acclaim for it's razor sharp handling, "better than anything ever built" (Motocross Action Online).
