KICK START QUADRANT A65
Kickstart quadrant for the BSA A65, engaging the kickstart shaft to turn the engine over.
This is a kickstart quadrant, and the catalog description names it for the A65 — that's a BSA model, not a Triumph, despite what our manufacturer field on this listing says. The quadrant is the toothed arc that engages the kickstart shaft pinion, translating the arc of your kick down into the ratchet action that spins the engine over.

In the parts books it turns up under the INNER TIMING COVER and GEARCHANGE MECHANISM figures, which fits how this piece works: it lives behind the timing cover and interacts with the gearchange side of the kickstart mechanism. Wear here usually shows up as a kick lever that slips or doesn't engage cleanly, so if you're chasing that complaint this quadrant and its mating pinion are the first things to look at closely.
Our records only show this part turning up in two catalog rows, both from the same narrow window, so we don't have a long fitment history to lean on. If you're sourcing this for an A65, double check the tooth count and shaft fit against what's already in your engine before you commit to it.
