Fit for Lifan Xpect
Bought this to replace the battery for my Lifan Expect 200 cc dual sport bike. Aside from the battery bracket not fitting over it, it’s been perfect. The battery bracket, in my opinion, is not really needed as the seat holds the battery securely in place. The bracket might fit if I bent it some or made some other modification, but I havnt bothered.

AVOID
Thank you Amazon for refunding this, but I can't imagine this battery works for anybody. No matter what I did it just COULD not hold a charge. I suspect that although the battery looks big, internally it is not anywhere near the specs it's supposed to have on paper.
