I’ve brought this question up before, but I’m still not convinced if there is an exact answer. I have a T214 which is a version of the T100 according to the info I’ve found on several sites but it still is confusing about the size of the front tire. And, although several iterations get mentioned but rarely do I see the T214 mentioned when specs are talked about. My bike has a 17 rear and a 19 front but about the only thing I’ve been seeing with a 19 front is the Steve McQueen version. On Bikez is specifically says 17 both front and rear. so Does anyone have a spec from Triumph that says 19" front?
Doing a Google search for “Triumph T214” and looking at the pictures in the articles and sales adverts returned it sure looks like the front wheel is bigger than the rear in all the pictures I’ve looked at. And zooming into those pictures that are clear enough to show the tyre markings shows 19" size marked.
Nice one, Sherlock.
