Frequently asked
What chain size does a Harley-Davidson RA1250 Pan America S use?
GarageDex's manufacturer-catalogue data shows the 2021-2025 Harley-Davidson RA1250 Pan America S uses a 530 chain with 19-tooth front and 48-tooth rear sprockets from the factory. (128 links)
What is the stock gearing on a Harley-Davidson RA1250 Pan America S?
19-tooth front and 48-tooth rear from the factory, part numbers front JTF985RB, rear JTR7085ZBK.
What changes if I go +2 teeth on the rear sprocket?
Going up 2 teeth on the rear sprocket (or down 1-2 on the front) lowers the gearing: quicker acceleration off the line, but a lower top speed, and the chain usually needs to be 1-2 links longer to keep enough wrap on the front sprocket - a shop or the sprocket's fitment chart will confirm the exact link count for that combination. This is a generic mechanical rule, not a claim about this specific model's aftermarket options.
How many links does a Harley-Davidson RA1250 Pan America S chain have?
128 links at stock length and gearing, per the manufacturer catalogue.
