Frequently asked
What chain size does a KTM 1290 Superadventure S use?
GarageDex's manufacturer-catalogue data shows the 2021-2024 KTM 1290 Superadventure S uses a 525 chain with 17-tooth front and 42-tooth rear sprockets from the factory. (120 links) Chain and sprocket sizing varies by year - see the table for each range.
What is the stock gearing on a KTM 1290 Superadventure S?
17-tooth front and 42-tooth rear from the factory, part numbers front JTF1904RB, rear JTR899.
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 KTM 1290 Superadventure S chain have?
120 links at stock length and gearing, per the manufacturer catalogue.
