Tyres For Cbr 250 R

[happymanme]

hi i'm looking for suppliers of both new and secondhand tyres for a cbr 250 r in the following sizes 110/70 17 and 140/60 17 or 150/60 17.

bridgestone bt90/96 or dunlop gpr70

if anybody has these tyres for sale or knows where i can get them at a reasonable cost let me know.

also chain and sprocket set for the same bike.

if you have other makes let me know then i can decide if i want them or not.

thanks very much allan
