not sure how many amps it takes to start an r1200r or similar machine. anyway, i'm, thinking if you have a female cigarate lighter type plug connected directly to your battery and then fabricate a cable with two male lighter type plugs, you could plug one end into a buddy's car lighter plug and then jump start. my car has two lighter plugs one is probably fuzed i think the other goes dierctly to the battery. the advantage of this might be its easier to use and maybe it takes up less space than conventional cables.
i'm on the second battery (6kmi) with my 2010 bike and the battery monitor i use tells me its down to 31 percent service life remaining. not sure why the bike seems to be so hard on batteries as the bike is usually connected to a smart charger when in the garage.
any feedback appreciated, even if its just to tell me its a stupid idea.
