Looked into this afew years ago to change the wheels on my harris,,, if you just want straight spokes then mark 2 bandit 1200 wheels will drop in same spindles, bearings and most spacers are the same, disc offset is 2mm off but slingy discs fit. if you are after the 2007 wheels specifically then you need 600/750 rear as they are 5.5 inch,
1100 front brgs 20x47x14 rear 20x47x14
600/750 frnt 25x52x15 rear 28x52x12
so fronts needed are 20 x 52 x 15 which are 6304
rears 20 x 52 x 12 which are BB1B447205A
then it gets complicated with the sprocket carrier so I gave up and fitted spoked wheels instead!!!!!!!!!!!!
