Frequently asked
What chain size does a KTM 890 Duke R use?
GarageDex's manufacturer-catalogue data shows the 2023 KTM 890 Duke R uses a 520 chain with 16-tooth front and 41-tooth rear sprockets from the factory. (118 links) Chain and sprocket sizing varies by year - see the table for each range.
What is the stock gearing on a KTM 890 Duke R?
16-tooth front and 41-tooth rear from the factory, part numbers front JTF1902RB, rear JTR897.
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 890 Duke R chain have?
118 links at stock length and gearing, per the manufacturer catalogue.
