Changes on the RM-Z450 include new graphics, the yellow front number plate, yellow/black shrouds (rather than the yellow/blue of the ’08), and beefed-up engine cases. Displacement. I'm more specifically looking for the top speed of a late model Suzuki RM125 to settle a claim. The average top speed of a 125cc bike ranges from 55 to 80 miles per hour (mph). What is the top speed of a suzuki rm125 1977 b? 68 mph depends on your sprockets. tf oe gj yh wg lq jo ia wc ix
