front brake disc - torx key size?

[WindyChuffer]

Whats the correct size torx key for installing / removing front discs on a 12GS?

(before I go and round them off with the wrong size key !)

Cant see an answer to this in this forum / riders manual / haynes manual

thx.

try them all, the biggist one that still fits is the correct one, dont forget to heat the bolt up to soften the threadlock

All done, thx.

Cant remember which size Torx I actually used, but used the biggest that would fit. Top tip.

Easier than I thought to do a complete wheel change (including front pads + fit discs).
