This thread scares me.
This "Upgrade Kit" is a silent customer goodwill action that Triumph has decided to do for the time being. I am sure, that Triumph, having limited resources, felt that doing this through through their dealership network was the only way they could help those in need and still afford to do so.
So, I am sure that each is approved on a case by case basis that is judged by parameters that I know nothing about.
Again, Triumph does not have to do this. This is not a recall. This is not something that will happen to every bike. Some bikes will get passed over due to things like abuse. Bikes that have no verifiable problems will not get it. We don't really know what problems will qualify a bike except for possibly the major issues.
Triumph's legal and ethical responsibility to these bikes ended at the end of the two year warranty period. After that, they owe no one nothing.
I don't want to see a thread like this imply that all bikes should get an upgrade kit as in a recall situation. I wouldn't doubt that this will cause a frenzy of inquiries and in a worse case scenario cause Triumph to suspend doing this for the few who actually need it.
