Below: Here is Weiss back home. With Bench Mark Works' 12 volt system and 200 watts of power, the bike has a more powerful headlight, a headlight modulator, and Hyper-Lites brakes flashing LEDs none of which can be used on the original 6-volt, 60-watt BMW and it runs beautifully. The 12-volt system also allows me now to wear an electric vest or jacket, power a Garmin Zumo GPS, and charge my cell phone, which is impossible on a 6-volt bike. Of course, the new electrical system is independent of the magneto, which still powers the spark plugs in the engine. And just looking at the motorcycle, you cannot tell it has been converted to 12 volts (unless you notice the large 12-volt sealed battery).
|Later I installed a Shorai LFX14A2-BS12 lithium battery which is so tiny it surprised me. It fits easily into the /2's BMW standard battery tray, but is just as strong as a big 12-volt battery for a modern BMW.|
The Shorai site lists this battery at $159.95. However, you can Google it and find it for $16 less or lower prices with no tax and no shipping.
Below: An LED taillight/brakelight combination, left, can be run with 12 volts, as can a much brighter headlight, right.
