Replacement brake disc BMW F650ST

[nigelphoto]

Some technical advice please - MOT advisory yesterday suggesting I replace the front disc on my 1997 BMW F650ST, sharpish. The choice is BMW £188 (lol!) Brembo £108 (which is actually the BMW OE disc) PFM cast iron £84 or Armstrong wavy disc at £82. My questions

1/ does the Armstrong, which has more holes than a pair of Nottingham lace knickers, actually work?

2/ what about the PFM cast iron disc?

3/ or should I just stump up for the Brembo and go to bed happy?

Answers on a postcard . . . . . any help much appreciated.

PS F650 Forum is absolutely no help on this whatsoever as its absolutely stuffed with armchair generals

can't offer any experience related advice but gut feeling is go Brembo

Personal experience of Brembo are very good. Ran a pair of these on the Exup, could quite easily out brake a mate RSV and the FZR was a heavy old bird.

The BMW one may well be a brembo one anyway. The ones on my 1200 are. Cast iron disks tend to be better at dissipating the heat but I don't think that will be a consideration on a F650 and beside they rust much faster than steel disks.

Hi Boris, yes Brembo is the BMW OE disc but see the price difference in my first post - its all in the name! I will probably go for the Motorworks Brembo disc, but I am going to visit the BMW dealer in Church Stretton on Thursday who specialises in older F65O's and see what they recommend or if they've got a good condition secondhand one.
