AJC Battery Compatible with Yamaha YZF-R1 M 1000CC Motorcycle Battery (2004-2017)
The AJC battery is a direct replacement for the YZF-R1, matching the OEM specs with a 12V, 8.6Ah capacity that fits the R1's tight battery compartment without modification. Terminal placement aligns correctly, so installation is straightforward. It covers the 2004–2017 model range, making it a reliable option across multiple generations of the bike. Caveat: it's a sealed lead-acid unit, so it won't match the cranking performance of a lithium alternative in cold weather.
