350x rear disk conversion

[BigBossJake]

Will a 400 ex rear disk fit and work on a 350x? Does anyone know of a disk that will interchange?

if you are looking for a smaller rotor and better rear brakes, with some work you can get a liquid 250r caliper on it and get a 86-86 200x/85-86 350x rear rotor, cut 10mm off the diameter(not near as hard as one may think) and you got a awesome rear brake. depending on year, you may need a 85 or 86 250r bracket. A 450r rear brake can be gotten easy and cheap and could be a much better bet. 350x/liqiud 250r/250x/300ex/400ex/450r all have the same diamter axle, brake hubs are very similar and axle locknuts are. It should be fairly easy to make something work.
