The guys with earlier ohlins need to be the most careful. they had 8mm holes for the bolts whereas later ones were 6mm so less material removed. Radial braked bikes also have a 2mm more material thickness around the spindle.
90% of the breaks are avoidable so be careful and i always prompt a tyre fitter if they touch it as to how tight to do the pinch bolts rather than leave it to chance.
