from what i'm hearing, none of them want Triumph warranty work... which begs the question, if a business only wants to pick and chose, why would the guy on the other side of that equation want that as a business to rely on?
I believe that's a direct condition of the repore' the dealer has with Newman (here in the USA). Obvious, at least to me, a dealer has to 'know' how to warrant a claim properly, do the proper paperwork and bill the time correctly. Some dealers are good at it' some aren't. That encompasses all brands, not just Triumph. I hear horror stories from KLR owners about dealers who don't want to pursue warranty claims, not that they can't, they just don't take the time to follow the proper procedure, which, is different for each OEM.
Triumph has been very good about honoring warranty claims, especially on the Rocket. I imagine that warranty issues have cost the company hundreds of thousands just for the Rocket. I've had some warranty issues with my Bonnie as well and that was handled expeditiously as well.
To summarize it, I'd say that 90% of whether a warranty claim is allowed or disallowed, depends on the dealer and the way it's presented to Triumph.
To cite an instance in another brand....BMW. I ride with a fellow that has a 1200GS. He cracked the final drive casting, BMW uses a pressure die cast aluminum alloy final drive leg. His developed a crack. The dealer was hesitant to replace it so my friend went out and rode the bike hard off road and broke it in two with the resultant drive shaft failure and collateral damage. It was replaced under warranty but it cost BMW a lot more than if it was handled when the crack first appeared. That's the dealer and how he perceives a poroblem. If the dealer had attended to the defect right away, it would have just been the Paralever casting.
Not all dealers are created equal
