ROCKER SHAFT T20
Rocker shaft for the Triumph T20, also known by the older reference B201C.
This is a rocker shaft for the T20 model, listed in the parts books as 70-3225, with the older reference number B201C also appearing on the same part. A rocker shaft is what the rocker arm pivots on inside the cylinder head, letting the arm rock back and forth as the camshaft pushes on one end and the valve gets opened on the other.

Our records on this one are thin - we don't have expanded fitment notes or figure titles to draw on beyond the T20 designation itself. If you're working on a T20 top end and need to confirm this is the right shaft for your particular engine, give us a call and we'll sort out the details before you order.
