Not so - they are all(*) 12 volt systems and have charging voltage in the same range (13.5 - 15.3 volts).
(*) Exceptions: Some cars and bikes made before the early 1960s and some mopeds and other very small bikes have 6 volt systems but your bike is not one of them. Even a cbr125 has a 12 volt charging system that is completely compatible with any automotive charging system less than 50 years old. You can jump-start it from a car battery no problem. I've jump-started bikes from car batteries many times over the years.
Oh ok. Thanks Brian
Good to know! Cargo Brian knows what he's talking about so I guess you're fine. Congrats on starting the bike!

I have a battery charger, I'm @ don mills n Sheppard .... I don't have a bike right now so I can't come to assist with the charger. if you wanna charge your battery for half and hour or so ... you could also go buy one at Canadian tire that way you have something to charge your battery during the winter.

Just got back to Toronto, or else I woulda offered to help. Shoot me a PM if you still need any assistance later.
I ran my battery into the ground a bunch when I first got the bike and then struggled everyday through winter with it dying, so I became somewhat of a bump-start guru...

Keep an eye out on Crappy Tire flyers for the CTEK 3300 unit which is designed for cars, bikes and winter charging (with indicators right on display) and comes with multiple attachments which helps.
As mentioned above, if you cannot start it on the first go, don't bother trying again - your next best bet is to bump start the bike by throwing it in either 3rd or 4th gear (the higher the gear the better, a lower gear will not help) and just run down the street like a mad man/woman fire and pop the clutch lever quick and pull it back in and see if she goes. Sometimes this may not always works so trying it a couple of times might be your best bet (this will test your endurance
.
If all else fails, the next solution is to find someone to give you a boost with the car off and in order of installing the cables (+ then - and then when removing - then +). Give it about 15-20 sec before trying to fire it up and see it turns over. If it does, try not to turn it off until you have ridden the bike for a little bit to recharge the battery, once you get home kill it completely and then try turn it back on and see if it fires up again, if so put on the trickle charger over night.

Buy a portable booster pack. Easy peasy, can boost your bike, your car and some even have inverters in em for portable AC power as well. I keep one in my trailer for the track. Use it to run my little compressor as well and loan it out to people with dead batteries. Usually can find em on sale at crappy tire for $50-$60. I have accidentally killed my battery a few time on the track bike by bumping the kill switch when loading(no key) so it comes in mighty handy.
So you are saying that one can purchase a brand new battery, completely drain it and it will NEVER function properly again?
I have never, ever heard of this before. How about you show me the source of this information?
Yet you give bad advise yourself.
Happened to me twice with two different bikes. Afterward, I constantly had to trickle charge the battery. If i didn't ride the bike for anything more then two days consecutively the battery would be dead. I have two batteries like this sitting in my garage - one for a 125 and one for 250 you can try them for yourself if you would like to.
I don't actually know why the batteries aren't holding the charge though as I never completely drained the battery - I only suspected that the previous owner of the bike did - i.e. leaving the lights on. Also I never said it will NEVER function again - presumably maybe you could take it somewhere to get it fixed - but I just bought a new battery as it wasn't that expensive.

Dunno... my batteries been through hell.. maybe my experience with it isn't relevant though, cause I'm pretty sure my batteries powered by magic.. it shoulda been dead long ago
Whole lot of misinformation in this thread.
Discharging a battery down to almost 0% capacity will damage the sponge lead on the battery plates, so it will never be as good as it was before that. Repetitive deep discharges will kill it quickly.
You can boost start a discharged battery with another battery providing you are not applying a charging voltage eg. running engine. Using the bikes charging system to charge a dead battery is a bad idea because you can overheat the stator or rectifier from the high current going into the battery, and the battery plates can be damaged from overheating, water loss etc.
Basically, a battery should only be charged at about 1/10 it's ampere-hour rating (AH) for longest life, and most other starting/charging methods exceed that.

If u use 2nd gear, u'll need a faster speed to jump start the bike.
1st gear will bump start at a lower speed but give u a jolt (tire skid). Your friends needed to push you faster, and tell em quit smoking
