after contemplating selling the project to make room for a newer bike, i decided to keep it and at least finish it, so someone else will get the chance to ride the bike , and it doesnt get hacked up. was my first bike and all. so heres the tire sizes alot of people have been asking for. the front tire is very close to lower forks so if you have a fender or brace you will have to moidify maybe, im not at that stage so far. shikno 10SR 712R tires rear size is 120/90-18 and the front is 100/90 -18. good tires by the way. in light rain they give just enough to mini drift. or maybe thats the unstableness and slowness of a cb360. i dunno
