But why would it happen again. I thought the bearing failures were due improper installation and installing it correctly would solve the problem. If that is the case, it is odd that Triumph didn't pay for at least some of the labor. They've been pretty good about it in the U.S. when the failure was due to manufacturing error.

I think it's his first Mike. Low mileage so took longer to self destruct.

Historically, these "faulty" bearings needed 10000 to 16000 miles before a problem is noticed. I believe there are different issues at fault to these failures.

In the original bikes, circa 2004-2006, the bearings were cheaper non-sealed ones that needed good oil lubrication from the sump. Wouldn't you know, that the oil sump design was changed in 2006. Means to me, the bearings didn't get lubed enough and their quality came through.

The issue with some newer bikes, 2006 and later, were because bearings got installed wrong which prevented them from getting lubed. This lead to even faster failure on the order of 3000 to 5000 miles.

These days I think you can rest a little easier because the bearings have been replaced with higher quality, fully sealed ones and usually come preinstalled with the whole torsional dampener unit so there isn't any danger of bad installation. Took a while for them to get it right but I'd have confidence in the replacement if it was done within the last year or so.

My Husband BritGuy just had his replaced, Triumph covered it even though it was a year out of warranty.
Your not the first & wont be the last.
Good luck
