The straight conversion never works, I think we do a good deal better down here in the under-globe realms on the straight conversion.
As the Oz pricing is online, you're probably better looking at the starting price differential we get and convert that - assuming like Oz your prices online are the rideaway and not excluding onroads etc? Take the GT at AUD$37,550, Chrome GT at AUD$38,990 and Storm GT at AUD$39,890, I'd therefore guess with the Chrome GT at NZD$41,990 then the NZ Storm GT would land at ~NZD$43,000? Still defs not worth a trade in...
I do think that the increased rev limit is interesting, in that all the chat about raising the redline on the standard bike was all "oooo no, the TFC has different valves, don't do it" yet the official word on the Storm is other than lighter wheels the rest is tuning and aesthetics. I hope Penner Tune V2 raises the redline for the rest of us!
