I was fortunate to work at a sports car dealer back in the early 70's that sold both new Triumphs and Datsuns. I got to drive brand new TR6's and 240Z's quite often, and loved both. They had similar power, ride, and handling: Quick, comfortable yet firm ride, and cornered great. I take exception to the idea that the TR6 was so outclassed by the 'Z. Certainly 'bouncy' was not part of the experience (note that the cars were new, not riding on 50 year old fatigued or rebuilt components). Datsun apparently considered the Triumphs a direct competitor, as they soon demanded that we stop selling Triumph under the same roof. We had to start a separate dealership down the street and split the two brands.

I'm guessing that the author of this article may not be a big fan of the old Brit bikes. One of the reasons the Norton Commando was (and still is) popular is that the new 'Isolastic Suspension' suppressed the shaking and rattling that the British twins were plagued with. After 2000 RPM or so, they're as smooth as an inline 4 (I've owned both). As for flexing, the 1975 model also added adjustable vernier Isolastic mounts so that the owner could tune that out of the suspension (previous models required shims to do that). Regarding leaks, well, as owners say: 'What does it mean when your Norton leaks oil? It means it's got oil!' -Be happy!
