BSA A7 A10 Engine Sprocket – 22 Tooth 2-Lobe Front Sprocket (45-2774 / SJ828)

If you're working on a classic BSA A7 or A10, this is the front engine sprocket you need.

It's a 22-tooth, 2-lobe design, which is what a lot of those twin-cylinder bikes ran.

Part numbers are 45-2774 and SJ828, so it matches the OEM spec.

It's brand new, so no hunting for a good used one at swap meets.

The finish is silver, standard steel.

This is a replacement part for the primary drive, so if your old one is worn or you're changing gearing, this is the ticket.

Made for the A7 and A10 models specifically.

Classic bike guys know how hard it can be to find decent driveline parts—this one's ready to bolt on.
