I have my SP1 all apart to change the fluids and add a few things....I decided to have a closer look at the battery and couldn't believe what I saw.
The battery is a Western Power Sports CTZ12S with a date code of "10-02-02". I read this as October 2, 2002, but maybe its Feb 2010? I've never seen any battery go 11+ years. Anybody have any experience with this brand of battery and the date code to verify this?
I bought this bike in late 2010, and haven't had any issues with it, but I do keep it on the trickle charger if it sits for more than a few weeks.
