BSA B32 Parts & Spares
The B32 is the competition 350 in BSA’s pre-unit single range: the trials and scrambles counterpart to the road-going B31, built on the same architecture as the 500cc B33 and B34. Alloy top ends, competition gearing and lighter cycle equipment are what set a B32 apart, and they are also the parts that wear out or go missing first.
We hold B32 components alongside the rest of the B-series, which matters more here than on most model pages, because a good deal of the machine is shared.

B31, B32, B33, B34
Those four names describe a grid rather than four unrelated motorcycles. The B31 and B32 are 350s, the B33 and B34 are 500s. The B31 and B33 are the road models, the B32 and B34 the competition versions. Crankcases, gearbox parts and much of the cycle equipment run right across the family, while barrels, heads, gearing and the competition-specific fittings do not. If something is not listed under B32, look at the B31 page before assuming we cannot supply it.
