A close friend bought a Triumph brand new and was overwhelmed with maintenance issues. Finally forced the dealership to refund his money. Bought a Honda and never had another problem.
When I was about 12-13, A kid was killed on a Triumph the first day he bought it. His mother (at the scene of the accident) told the guys standing around to take the motorcycle if anyone wanted it.
These are my only experiences with Triumphs.
Personally on street bikes, I've always been a Harley guy and no stranger to maintenance problems either.
The z900RS Kawasaki is looking good right now.
