Just thought I'd share my recent experience with NRMA comprehensive insurance for my '03gpx250r.
I was with them last year (paid about $520), and they sent a renewal this year for same price. What was different however, is that last year I had choice of repairer - this year it is now considered an optional extra that will cost me an extra $70!
The end result was I rang around and found a competitive quote from Arista (thanks to your various references from this forum

I thought NRMA was sneaky because unless I read the fine print and noticed that I no longer had the choice of repairer 'option', I would have been none the wiser. I've also heard that NRMA will be posting pics of crashed bikes on the net forcing their repair companies to bid on the price of repairs, and NRMA will give the job to the cheapest bid...I don't like what this might mean for the quality of repairs done to my bike...
Cheers,
Troy
