Ral Micron 40 aka Rossi R40 sport engine, mfr # 23M40 (Rossi # 23R40). This is the newest version of the classic Rossi 40 made up until around 2000. Everything is Rossi - documentation, packaing etc, just sold under the Ral Micron name. The case is machined for the Ral emblem and you can see what's left of the I at the bottom.
This version is a friendlier engine than the QB400 FISE engine, with 3 ports and a smaller carb. It'll stick kick the pants off of most engines in it's size. True ABC construction, mini tuned pipe, legendary Rossi quality and power.
Engine is 100% new in the box, has never been mounted, fueled or fired. all hardware still sealed in bags. Pipe has some dings from the less than spectacular packaging from Rossi.
