Mine is also a Optimate 4. I have never heard of the cold having a detrimental effect on batteries (Unless yer in Iceland) . (Yes, you will have slow cranking going on due to the oil thickening and a tighter engine) I haven't heard of any current drain issues with the s1000, unlike my GSXR1000...
For me it's important to have more than one line of defence, that's why I have a cctv camera which sends a photo to my phone if triggered. A text alarm when triggered to a 2nd company phone and one other secret device.....oh and the tracker.
Welcome. Just leave it in Race mode. 3 of us on 15 S1000's playing about with all the settings in Almeria last month when we all got destroyed by this chap on a S1000. "I just leave it in Race mate" was his words.
I got caught as well mate. Bought one of those ?11.99 units which was accurate to a mile lol. The Maplin device contains its own battery which lasts about 4 days if the bike battery is disconnected which also helps when installed on the drone.
