1962 Triumph TR6


1962 TRIUMPH TR6 NOMENCLATURE
Of course, this is tFor the 1962 model year the only Triumph TR6 produced was the Triumph TR6 S/S Trophy. Gone were the "C" & "R" designations, leaving the TR6 to become very much a Triumph Bonneville without the second carb. 1962 Triumph TR6 S/S engine & frame numbers ran from D16189 to D20308, & were built from October 26, 1961 to July 31, 1962.

ENGINE CHANGES
Starting with Engine #D17043 the crankshaft balance factor went from 71% to 85% where it would stay until the introduction of the 750cc Triumph TR7 in 1973. This required a new crank with pear-shaped bobweights. Starting with #D17552 the troublesome alloy oil pump was replaced with a cast iron oil pump. The infamous "Slickshift" foot clutch is quietly dropped.

DETAIL CHANGES
The 1962 Triumph TR6 got new fuel petcocks designed not to jam like the units they replaced. The oil tank was now completely rubber-mounted. A Lucas K2F magneto replaced the R2FC competition magneto (for reasons of cost). Handlebars were now flatter & the seat, while shaped the same, now had a gray top & lower trim band.

The last pre-unit Trophy, a 1959 Triumph TR6 S/S, rolled off the assemblyline on July 30, 1963 with Engine #D20308.
