Hi Chaps , Decided on the front end for my 350lc track bike which will be Tzr 250 2ma forks with a F2 wheel , 320mm disc + spacer and a blue/gold spot yam caliper . But i'm struggling to find a disc to fit . Been looking at a 2004> FJR 1300 disc (320mm / 6 bolt pattern) which might fit but seem a bit pricey and can't seem to find any other model using same disc D'oh !. Have read somewhere that a 2004 R1 disc fits but the 320mm ones i'v looked at have been 5 bolt pattern and earlier ones with 6 bolt pattern are 298mm (pants). Could use a standard lc wheel with tzr disc + spacer but would like to use the f2 wheel as its slightly wider to fit the am22 tyre + lighter . Any info would be most welcome . Thanks.
