KEMIMOTO Lithium Motorcycle Battery YTX14-BS/YTX9-BS, LiFePO4 Lithium Battery 12v 6Ah, Pre-Charged Powersports Battery, with 5 Universal-Fit EVA Spacers, Compatible with Motorcycle ATV UTV Jet Ski
The KEMIMOTO LiFePO4 battery works well for the Triumph Tiger 900 because it fits the OEM YTX14-BS battery slot without modification, and the included EVA spacers handle any minor sizing gaps cleanly. At 6Ah and 12V, it meets the Tiger 900's starting demands while saving noticeable weight over a conventional lead-acid unit — a genuine benefit on an adventure bike. Caveat: some Tiger 900 owners report needing to verify compatibility with the bike's battery management system before committing.
