Googled and found this relating to Florida :
Zem Bower Auto Centerand although it relates to cars, it would seem that the answer is, "No" !
In the UK the answer is NO, providing the Service schedule is followed,
any such work is carried out by a competent person,
and parts used are either genuine "Triumph" parts,
or are of an equivalent specification and quality.
To be certain though I would fire off an email to Triumph
asking them specifically, so you then have their reply in writing

Cheers
