Battery that came with the bike and the second purchased battery, 2 different batteries. Original battery feels sloppy and slightly heavier, but can get the beast up to 28 for a short period. New battery, 26 forever and noticably more torque and torquey 90% of the life. Both 25 miles 100% throttle.
UU750 second battery:
2 tanks of gas for the beast. No secret in my house how much I love this bike!! Thank you
