For those who asked:
I've been quoted $1000 (AUD) for both wheels (NC35 front & rear), delivered to Perth.
I guess they are shipped from the UK on demand...

no more info from the manufacturer on the weights though.

a pair of new alloy dymags (not the composite) are less than £800 and that lets you use the 160 section rear tyre designed running the 160 on the 4.50" rvf sized rim dont feel good and flatens the profile shape.

Aftermarket wheels on a single sided swing arm ???????? may be ok for road use
remember the 1994 TT senior race a certain rider on a rvf750. Make sure there are no doubts in the manufacturer for sure .......

This Delvis seems as if it may be something to do with D&K. D&K would be more suited to tarmacing you drive than dealing in motorcycles or anything else your life may depend on! CAUTION.

DK bikes are a bag of shit worth stayin away! 1 good thing though is a young lad matt (rip) worked there and wrote off a brand new duke clean out the box HA well deserved for them c****! the spares are all good especially the new stuff they just like to charge on a person by person basis as they are stuck up there own arses and think they are better than you because they work in a shop. idiots!!

hmmm, that's interesting.
Looking at both websites, the design is almost identical and D&K has a top-menu link to Delkevic, so maybe they are quite closely allied as retailer and Manufacturer...
The addresses aren't in quite the same place, but not too far apart either (I don't know, maps of british places are all greek to me)
I did hear in the other 'D&K Motorcycles' thread that as a dealer they were a bit unscrupulous in sponging money off the unsuspecting, not that it bothers me alot as I live on the other side of the world, but I doubt whether it would affect the quality/reliability of anything which came out of Delkevic...

delkevic are russian.. D and K are a shop in stoke on trent .. just cos a shit shop sells something doesnt make the item shit.
