It's the owners manual that strated this rumor. The owners manual states "Use BT020 or Metzler Roadtec Z6 only".
Like I said, unless the ABS is some how pre-programmed for those 2 exact diameter tires and any other diameters (same size tires from different manufacturers can vary quite a bit) screws up the ABS.
I'd hate to be stuck with just 2 tire combos.
I'll see if Triumph NA has other ideas. I already complained about the stupid seat attachment to them.
Thanks,
