19 Tooth Gearbox Sprocket

Introducing the TEC 19-tooth gearbox drive sprocket, designed to deliver multiple benefits:

This sprocket effectively reduces engine revolutions, resulting in fuel savings and a smoother riding experience akin to having an additional gear.

If you’re tired of hunting for top gear when you’re already there, this upgrade is tailor-made for you.

We offer both 520 and 525 size sprockets to accommodate the corresponding chain lengths.

Please ensure you select the correct size sprocket from the drop-down menu on this page.

For Triumph models produced from 2000 to 2012, the chain size is 525. However, Triumph switched to a 520 chain size for some bikes starting from the 2012 model year. Therefore, if you’re ordering for a bike from this year or beyond, verify the chain size.

You can easily identify your chain size by checking the side links of the chain, where it will be stamped with either 520 or 525.

Please note that this part is exclusively compatible with air-cooled Triumph Twin models and will not fit any water-cooled models.
