YamCafe Posted February 2, 2017 Share Posted February 2, 2017 Hi,I have a Yamaha SR 125 that I am going to turn into a Cafe racer. The engine is the main issue as I had a brand new engine rebuild that was then heat seized by a friend but that's another story. I can't rebore the barrel anymore due to it being done to its limit before. I would like to know if there are any either 2 stroke or 4 that should fit on the same mounts without the need to alter the frame. Or would it be worth to go for a 250cc and upgrade the breaks and suspension?? Quote Link to comment Share on other sites More sharing options...
