TURBOKIT R-TUB LACADO exhaust for 50 RIEJU RS1 4, 5 and 6 speed motorcycles

High performance muffler, deep drawn body, welded, vacuum in fine varnished jail, volumes and counter cones designed for high performance, a little hollow at the bottom but very efficient at high speed, ideal with at least a 19mm carburetor and a well released ignition CDI, possibly a cylinder with diagrams higher than the origin and good valves. Single silencer black anodized. Arises on old 50 RIEJU RS1 mopeds with 2-stroke engine 4, 5 and 6 speeds.
