Sorry but I don´t agree with you about to fit cheapo alternatives on brakes.
Alf, it's not me your disagreeing with, it's the wider global motorcycling community.
I looked hard to find someone that would criticise them but could only find glowing testimonials, and I covered a lot of sites. As I said, it may have happened to someone, but by sheer numbers, they are a winner.
The only negative feedback I could find was an FJR site that said you may as well throw yourself of a bridge, you at least get to choose the time and place.
Funny thing was, not one of them, or anyone they new first hand, had a problem, it was all hearsay.
Alf, ignoring my own experience with these, do a bit of research (as I did) and you will find little support for your opinion on these rotors.
Pick a make, pick a model, pick a country, pick a forum, they are very popular.
A failed rotor is after all a matter of fact, not opinion.
You are of course entitled to your opinion, as we all are, and I'm not disputing your experience but I think in this case the numbers alone are against you. Everybody here is happy with these brakes, and I'm sure there are some very heavy brake users amongst us, and this should be the advice we pass on.
