RM125
The Suzuki RM125 and RM250 began production in 1975 and continued until 2008. The RM125 and RM250 were discontinued due to the decrease in demand for two-stroke motocross bikes. The 2007 model had an approximate output of 41.06 wheel horsepower (30.2 kW) at 11,500 rpm, and 30.2 nm of torque at 10,500 rpm.References
