Hi guys New to the forum I’ve picked up a project and the engines wrecked so thinking about putting different engine in I’ve found a nice 2016 areox for a good price but unsure if it fits in the sr50r frame any info much appreciated
Welcome. You can buy engine mounting cradle kits that will let use certain yam engines in Aprilia frames, for example RZ350 or Banshee engines into RS250 frame so it's possible but don't know if they do a kit for your project. You could call a few suppliers and find out though.
