The 450R cylinder is Nikasil plated. The 500cc FST I have was bored and replated.
I have no idea about the CR250.

I do not have the answer for you but spoke to a gentleman at Maxpower regarding there 480 big bore and he seemed to know what he was talking about. But when I had my engine apart, I was looking at cylinder wall thickness , it is not real thick to begin with. Would a new aftermarket cylinder be a better and more durable choice.

Does anyone know the base hardness of this coating and how thick it's normally applied ?

(Any details about the process would be appreciated) ... As in firearms, prep is 80% of the quality of the finished job ...

I would like to know if the poeple doing this after Honda know it well enough or if it's a no brainer coating ...
Here in wisconsin we have 3 big places that do this. US Chrome, Max-power, and Millinium. The guy that is doing my motor assembly sent mine to Millinium(he has used all 3 at one time or another). Of the builders I talked to they all seem to use millinium. When I talked to Kenz down there he told me he used millinium because they are the best and thats what I here from everyone else. Millinium's site
