August 1, 201214 yr Hi all been looking at a Yamaha ty175 as a project bike to restore, does anyone know if a 125cc engine unit will fit straight in for road legal reasons Cheers for any help
August 1, 201214 yr Hi Tony Ive had a few ty's. Just put a ty125 cylinder and piston kit on. The bottom half of the 175 engine is exactly the same as the 125. My first ty175 was originally a 125 with a 175 cylinder. The front exhaust pipe of the 125 is the same as the 175. Only the silencer is different. hope this helps.
August 2, 201214 yr Author Hi mate yeah thats a great help thanks very much, the bike is off road at the moment and was hoping to make it a 125 road legal bike to take test on....would the bootom half swop make it possible for me to register it as a 125 do you know?
August 2, 201214 yr You'd probably have to chat it over with the DVLA. I probably shouldnt say it but you could try and get a 125 frame and log book and put a 175 engine in it and nobody would be the wiser. On future posts, be more specific with your title i.e. 'ty175' and you will get a load more posts. Good luck with the project. Edited August 3, 201214 yr by gazzaecowarrior
