The BSA and Triumph lightweight singles motorcycles were classic British bikes known for their single-cylinder engines and for their rugged performance.

Derived from the C15 model, these low capacity single cylinder motorcycles were ideal for beginners. Later B40, B44, B50 etc ... offered increasing power at 350, 441 and 500cc. The B44 and B50 became popular for off-road use, and was the most powerful in the lineup. These models are renowned for their simplicity, reliability, and vintage charm.

At Stainless Classics we produce many items as shown below for these singles, from cylinder base nuts, studs, side stands, springs, to rocker box bolts and much much more. All stainless, and machined to keep your BSA looking as good as the day it rolled off the production line. Always refer to the parts book for appropriate fit for your model.
