Hi gents I expect mainly the VFR/rvf crowd may help
I’m in the process of buying a bros650 to race and I’m looking at potential weight savings and upgrades!
The bike is amk11 so has 18” rear wheel!
May stick with it or look at vfr/rvf replacement as I think there lighter?? How do people get on with bt09 tyres for track ) not allowed warmers)
Does anyone have spare front wheel a fork lowers I could graft onto bros’s legs?

Cheers mark

If you mean you're considering replacing your 18" rear wheel with a rear from the NC30 or NC35, you ought to know the NC35 is 17" and costs a bleedin' packet. Seen them offered at £500+. The NC30 18" is considerably cheaper but I've no idea if it's a straight swop.
