IMHO {having ridden t120, tr6,t100, T140, A50, A65 (BSA ask a friend) Commando & dominator and then new bonnevile & t100} . Of all the classic (pre 1990) Triumphs, the new triumphs most closely resemble TR3A ie they are stodgy & boring.
Then again all the triumphs in the early list above were unreliable & vibrated like a bad air-hammer some were fast (sometimes) but those were ALL shorter lived than a 1970's honda (but longer lived than BSA Spitfires!!!!!!!).
Original Triumphs were hard edged, short lived sports bikes. If you want modern triumph buy a Suzuki GSXR
Sorry buddies
