BSA Exhaust rocker complete
A complete exhaust rocker for BSA engines, pivoting on the rocker shaft to open the exhaust valve.
This is an exhaust rocker, complete, listed in the catalog under CYLINDER AND CRANKSHAFT for engines built in the 1969-1970 span. A rocker like this pivots on the rocker shaft up in the cylinder head area and transfers the lifting motion from the pushrod down to the exhaust valve, opening it at the right point in the cycle.

The manufacturer tag on this one says BSA, and other catalog listings we've seen tie this same rocker to BSA's C15, B44, and B50 models, so this is a BSA part, not a Triumph one. If you came here looking for a Triumph exhaust rocker, this isn't your part.
We don't have much more detail on this one beyond where it sits in the catalog. Give the shop a call and we'll confirm exact fitment for your engine before you order.
