what does the sr in triumph sr stand for

[rockerboxer]

i think i remember reading somewhere that sr in triumph sr stands for street racer, can anyone shed and light on this?, im currently building an sr engine.*(well collecting parts to fill my 1965 bonnie sr cases). there were a few mid 60s TR6SR models (all sent to USA) but no record of sr bonnies, however one or two t120sr models do exsist. when i saw t120sr cases on ebay i thought about an old unit frame id had for ages and i just had to throw a 65 t120sr look alike project together, any wise owls out there?

Don't think it "stands" for anything, as such. More to do with the model designation ie S for the sporty model, and R for road (as opposed to C for competition, etc)

Must admit I thought the SR moniker was for the US 500s only, rather than the 650s.

A google search shows Wiki lists about 3000 of them made 64-66.

In 65 and 66, the SR was about one third of all Trophy production.

And pics of them being restored etc.

With all the model designations, you'd have to think that some of them were just a convenient combination of letters ?

Hopethishelps.

HI.

Once upon the time "s" was for "side valve engine".  "R" I don't know.

Have a look to the forum on Triumph 3SE

Keep headlight on !

I think for the US market it just means SR (road)  and SC (competition ) for the early 60s Tiger 100s
