Canam370 is the go for handlebars in Australia.
I prefer to use steel handlebars for two reasons, the first (and major) is it looks 'period', the second, if (when) I crash, and it's a big enough to bend the bars, I can just put a foot on the footpeg and wrench them straight again and keep on riding.
I've had crashes big enough to bend thick wall, alloy bars and not been able to bend them straight again.
And I've never in 40 years had a pair of handlebars break on me.
