TEC 19 tooth gearbox drive sprocket.

This will drop revs and also save you fuel.

“Like having a 6th gear”.

If you are sick of looking for top gear when you are already there then this is for you.

We have both 520 and 525 size sprockets for the corresponding length chain.

Triumph models from 2000 up to 2012 are 525 chain size.

Triumph changed the chain size to 520 on some bikes for the 2012 model year, so if ordering for a bike from this year or beyond, check the chain size.

You can check your chain sizes on the side links of the chain it will have either 520 or 525 stamped on it.

This part will ONLY fit air-cooled Triumph Twin models. It will not fit any water-cooled models.
