Frequently asked
What chain size does a Yamaha YZF-R6 use?
GarageDex's manufacturer-catalogue data shows the 2006-2020 Yamaha YZF-R6 uses a 525 chain with 16-tooth front and 45-tooth rear sprockets from the factory. (114 links) Chain and sprocket sizing varies by year - see the table for each range.
What is the stock gearing on a Yamaha YZF-R6?
16-tooth front and 45-tooth rear from the factory, part numbers front JTF1586RB, rear JTR1876.
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 Yamaha YZF-R6 chain have?
114 links at stock length and gearing, per the manufacturer catalogue.
