What is the shift pattern for Triumphs in the 60s and 70s with a right foot shifter? The Nortons are one up and the rest down, BSA seem to be one down and the rest up, so I wonder what exactly Triumphs in this period actually are for the shift pattern.

= Up for up.

BSAs were also 'Down for up' - until around 1960.

BSA is the same as Triumph, first is down, 2,3,and 4 are all up. Not sure what L.A.B. meant.

Pre-unit BSAs (up to about 1963) were up for 1st (from neutral) then down for 2nd, 3rd and top. I think that was what Les (LAB) meant. So they were different from Triumphs of the same period which were the opposite (down for 1st from neutral etc).

Triumph's of the 1960's and 1970's with right hand shift per your question is 1 down 3 up for four speed transmissions and 1 down 4 up for five speed transmisions.

Yes that was indeed what I meant.

I didn't realise the terms "Up for up" (one down, and then lift the pedal UP to change up) and "down for up" (one up and then press the pedal DOWN to change UP) maybe isn't widely understood outside the UK?

As Tridentman said, pre unit (4-speed) BSAs both singles and twins would normally have had one up and three down (down for up) gear selection, which was the more common pattern, - until the early sixties, when BSA changed over to the 'Triumph' way.

I certainly understand the "up for up" designation but then I brought that understanding over to US with me from UK.
I guess that BSAs changed over when the change from pre-unit to unit (A7/A10 to A50/A65) was made. Triumph were always "up for up" as far as I can remember.

The (L/H gearchange) Norton Commando 850 MkIII being the exception, = one DOWN, three UP.

(The first motorbike I ever rode was an early sixties 90cc H*nda C200, and that was = one up, - three down, although it had a rocking heel and toe gear pedal, so I suppose one could say that the gears were, in fact, all DOWN) wink

It is understood by American riders too. Probably just loses some in the translation of black and white on a computer screen.

Actually, some pre-unit BSAs could go either way since the gearbox casting accepted installing the shifter cam detent plunger from the top or bottom. A Triumph pattern could probably be reversed too except that the cases were never drilled for the top position.

Just bought a Triumph T120 1962 and find that the shift is one down and 3 up, which is the opposite of my BSA 1963 Rocket Gold Star. Very annoying. Always crashing the gears on one or other bikes. My BSA has a RRT2 box with the gear lever reversed to the rear footrest. If I put a reverse cam plate in the RRT2 box would it result in the gear shift pattern being the same as the Triumph ?

Yes, or fit rearsets to the Triumph and reverse the gear lever.
