BSA B31 B33 & A7 A10 Rear Engine Plate Cover – Black, UK Made (42-4272)

If you're restoring a classic British bike, this is the kind of part you want.

It's a rear engine plate cover, finished in black, that fits a bunch of the old BSA singles and twins like the B31, B33, A7, and A10.

The big selling point here is that it's actually made in the UK, so you know it's going to have that proper fit and feel.

It crosses over to part number 42-4272.

It's brand new, but it's made to look and function just like the original part that left the factory decades ago.

Whether you're doing a nut-and-bolt restoration or just replacing a crusty old cover, this is a solid, authentic piece for your project.
