Triumph is a niche brand in South Africa. We have two dealers at present - Johannesburg and Capetown - operated by the same company that imports them. It has been like this for about the last two years - not sure before that. The Jo'burg dealer, where I bought mine, knows about my slip-on and the tune I put on the bike.
I do not want to come across as a wise-4rse, but I have never been too concerned about seller warranties (implied and express) - motorcycles or otherwise. Warranties effectively limit the buyer's rights under common law and are never beyond challenge. We also have a Consumer Protection Act (CPA) in SA, which no doubt would have been based on something similar in the UK or US. And in recent years, we have gained some even more powerful avenues courtesy of the internet and social media. I am always upfront with dealers - in terms of what I install on bikes and how far I am willing to take the discussion in the case of unrelated claims. And I stick to the principal stating 'if it is not in writing, it has not been said'.
I often do not even take the bike in for the initial 'warranty' service if I disagree with the
oil specification that the dealer uses - not talking brand or viscosity/grade here and not wishing to start another oil war.
EURO-5 engines represent the pinnacle of ICE technology presently. Not only in terms of emissions and fuel efficiency but also regarding
low friction,
close tolerances and QC reliability. The new Rocket's EURO-5 mill's oil should satisfy two specifications; JASO MA-2 and API SN - see
Oil Categories in terms of the latter. I discovered my dealer uses SG and that the Triumph website promotes SH, so I performed the initial oil change myself and informed the dealer in accordance and writing.
I also keep all spent oil filters, with dates and mileage marked on them, and I take photos at oil changes.
