As it turned out, I was in luck. The scooter was purchased from Battley Cycles and they add an SAE Battery Tender harness to every bike that’s sold. Does your dealer do that? It’s a very nice touch…
I sort of knew this — the Ducati GT1000 (blog) project bike from 2009 had an SAE harness installed, and that came from Battley also. But I guess I figured that a scooter would be different.
But in the case of the C 650 GT, you can also make your own SAE Battery Tender harness with a male accessory outlet plug on one end (photo above) and simply plug it in to the accessory outlet in the left-hand storage cubby.
Just make sure you get the hot lead (it’s the protected side) wired correctly!
In any case, I wanted to find out how hard it might be to access the battery on the C 650 GT, because I plan on adding accessories like auxiliary lighting, heated clothing, GPS and more.
Removing the Side Panel on the BMW C 650 GT
So far, BMW has not released a shop manual for the C scooters.
I sure hope they do sometime soon, because the owner’s manual is pretty slim when it comes to anything other than very basic maintenance, such as checking the oil, coolant level and tire pressure.
Funny how things have changed — the owner’s manual for the 1961 Heinkel Tourist I referenced in the BMW C 650 GT review is so complete, you could literally rebuild the entire engine using it and a set of basic hand tools. Well, almost…
The battery on the C scooters is located under the right-hand fairing side panel. The owner’s manual tells you that there are actually four fasteners, but the information is split across two pages, so read carefully.
BMW has employed Torx fasteners for almost everything on the C scooters.
Once the panel is removed, the battery is visible and readily accessible. This is when I discovered that Battley had already installed the SAE Battery Tender harness.
The SAE connector end hangs out the front, just under the right-hand side of the fairing, above the wheel.
Here’s a photo of the battery with the panel removed:
It’s a made-in-Germany AGM “maintenance free” battery, held by a metal strap. Notice in the photo that the red rubber cover for the positive terminal is loose; this is due to the connector for the SAE harness.
There’s plenty of room left on those terminals for all sorts of accessories, and the electrical system should be able to handle them with no problems, as it puts out 588 Watts, according to BMW. Can’t wait to start farkling it up!
The fuse blocks are also located in this section, just in front of the battery.
Otherwise, there’s not much else to see and it all looks packed pretty tight. It’s my understanding that Kymco partnered with BMW on some aspects of the C series scooters; I’m not sure what at this point.
So that’s all there is to it; a simple maintenance procedure — simple, at least, once someone shows you how!
ut since there are so few of these scooters out in the “real world”, I figure that any little bit of information might be useful to other owners or potential owners.
