2.5" = 2 1/2 inches = 63.5mm
8.2" = 8 13/64 inches = 208.28mm

just multiply the number by 25.4 to give you milimetre equivalent.

My humble opinion, (for what it's worth), What is the bike going to be used for ? If it is for Drag racing, Track days, etc - I would brace it. If it's for road use I would not think it would need bracing.

who knows what the future holds, 17'' rubber and hopefully ohlins all round is going to improve it, while its in bits im going to brace it, i will make it all myself and get my mate to weld it so price is going to be minimal
