From when I started biking in the 70's I only ever had Jap bikes (...well apart from a brief spell with Bultaco Sherpa 250 in 82' ) and I had some but extremely few problems over all (There was one major one in 87' Kawasaki GTR1000).
Fast forward to 95' and I deviated from the norm and went full blown Italian by having several Moto Guzzi's exclusively for over a decade. Everyone in the mainstream thought I was in for a whole load of trouble, but actually what I experienced was that the reliability statistic was pretty much the same as with the Jap bikes.
In 2006 I went all orange with a KTM 990 Adventure and was massively impressed with the quality and engineering design. It was an incredible bike, but even 'it' let me down by the side of the road in the second year of ownership. Turned out to be a loose battery connection, which I discovered by chance and fixed thankfully, but I was convinced at first that it was going to be expensive.....was I lucky? Maybe.
On my next bike (Harley Davidson XR1200) I ended up properly stranded in the middle of nowhere with a collapsed front wheel bearing but not much else. (Was very frustrating at the time though).
Prior to buying this Rocket 3R, i'd not heard of any significant reliability problems with Hinkley Triumphs. I have a mate who has had his 1997 Triumph Daytona 995i 'forever' and he rides it all year round most years and he's not had any major issues with it and regards it as a faithful friend. I keep thinking that it's getting worn out by now but it just keeps going just fine.
I do have a gripe though, about the latest bikes......all this electronics, sensors, software....gizmos.........I wish it wasn't necessary. Is this stuff making bikes better??
