Welcome. If you post a thread in our Dual Sport Forum, I'm sure you will quickly get several good tips on finding the correct battery for your HSUN bike.
Bought a 2009 Hsun 200 endure, she is sitting in storage awaiting a battery. The adventure begins. Lectured all 3 places I went too how my bike was made in China & I will have to schedule a trip to the moon to find a battery. Reading post to get the hang of the bikes exotic needs.
