The RM500 was Suzuki’s big open class 2 stroker, and while it wasn’t much faster than the 465, the revised Full Floater suspension was a bit of a revelation.
For more on the RM, check out this story on the ’84 model from PulpMX. This example underwent a “frame-off restoration” that included a repaint of the frame, all new bodywork, new seat cover, new Renthal gold chain, and new DG exhaust. The engine is on the first over bore (.25mm) and it’s “very low hour” with new seals.
