Another update.
Someone recommended these;

Just for the record, they dont f#cking fit either
If you look at the 1st pic, the problem is the inside of the bars. You can see a smaller diameter within which stops the fitment in the 2nd pic from going in properly.
The 3rd pic is just to show the difference in length.
Fitments aside, even holding the handguards in position, they would not fit the XT.
