The RM series is a model range of two-stroke motorcycles manufactured by Suzuki. The letters "RM" stand for "Racing Model" and the motorcycles produced with this prefix in their model names are suited to use in motocross racing. The first in the range was introduced in 1975 with the RM 125M, followed by the RM 125A, RM 250A, and RM 370A in 1976. Preceding the RM lineup was the TM series, which included the TM 75, TM 100, TM 125, TM 250, and TM 400. Motorcycles within the RM series continue to be manufactured today, the famous RM125 was discontinued in America in late 2007 . The 100 cc Rm100 was discontinued in 2005. The Rm250 was discontinued by the 2009 model year. This may possibly be related to changed class structure and lessened demand for 2-stroke motorcycles in the USA. From 1999 to 2004, changes to the RM250 made 15 more stock horsepower, and a lower seat height.
