TUSK Lithium Pro Battery TLFP-9R for Triumph Trident 660 2021-2024
The TUSK Lithium Pro TLFP-9R is a direct-fit replacement for the Triumph Trident 660, matching the OEM group size and terminal layout so installation is straightforward with no adapter plates or bracket modifications needed. At roughly half the weight of a comparable lead-acid unit, it reduces front-end mass slightly — a real benefit on a middleweight naked. One caveat: lithium batteries can struggle to start in temperatures below freezing without a brief warm-up period.
