Stud (bottom) engine to frame (10½ in. O.A.)
A 10½ in. bottom engine-to-frame mounting stud, Triumph part 21-0572 (alias S572).
This is a bottom engine-to-frame stud, 10½ in. overall length, listed under Triumph part number 21-0572 (older parts books show it as S572). It shows up in the parts-book sections covering engine unit fittings and footrests, which tells you it's one of the studs that bolts the engine into the frame cradle at the lower mounting points.

These studs take the load where the engine hangs in the frame, so they're worth checking for stretch, corrosion, or thread damage any time the motor comes out. If you're replacing one, it's a good idea to check the others in the same mounting group while you're in there.
Our catalog record spans several years of appearances in these fittings figures, but it doesn't spell out which specific model years or engine sizes each listing covers. Call the shop and we'll confirm fitment against your engine before you order.
