Finally got round to putting CBX550 bars on, very subtle difference, not sure yet whether it'll be enough. However, you get about 30 degrees of rotational adjustment so I'm playing with that. I suppose it also keeps a vaguely standard look...
TOP TIP FOR THE STUPID FOLK (ahem):
For a while, it appeared that I'd have to pull out and reroute all the wiring in the headlight, and that might not be enough to get the extra length for higher bars. This XBR is totally factory, wiring has never been disturbed, so I wasn't relishing being the one to spoil it.
And then it dawned on me... Loosen the headlight brackets, and slide them up the yokes!
Now I know this is obvious for almost all of you, but since I nearly DIDN'T realise it, I'm posting it here <red face>
