That is, if you turn your key on, and the dash does not respond with temp warning lights, etc., then you will not be able to jump start it, like you can with carburetor cycles.
so the answer is NO... that is all i wanted to know

yes ,,, if the battery is beyond dead , the cells will go and you will not be able to push start (usually the lights will not come on or dim if the batt is too low)


...but if those cell are good , then yes you can push start her and recharge the battery


sometimes , a dead battery is because someone has not been riding their motorcycle at least once a week , ... think they call them "week-end warriors"


if the battery cells are bad , check out Ridersdiscount on this site , they have Alien technology

My 2012 cbr250r wouldn't start on a completely drained battery. Left the key in and light on for ~2 hours, when I went back to it, nothing lit up, dash was off. Tried push starting without the battery (because I took it out but didn't bring the tools to put it back in). It would turn on for a few seconds and I can get it to rev pretty high, but then the orange check engine light would flash and the motorcycle died. Then put the battery in (still a dead battery) and it still did the exact same thing. It feels like the motorcycle decides it doesn't have enough power and so gives up. I had it revved >6k rpm from the sound of it, the dash would turn on and off quickly, tachometer would spin up and down, and no matter what the bikes turn off after a few seconds.

Now I'm just gonna leave it on a battery charger. hope that'll fix it. The battery was good before I left it draining yesterday

A battery can be drained of it's charge and still be good enough to hold a new charge.
It can also be drained and possibly have a weak cell and no matter what you do to it, it will never be dependable.

I tried it once when I was playing with accessory lights and the battery got too low to crank well but was otherwise "lit up". It didn't work. I could only get 3-4 bumps per attempt and it wouldn't start.

different experiences, different outcomes for different people..
all you can report is your own experience[s], which for me
was key in overnight, 'nothing' in the morning, tried clutching her
as usual for other [carburetted hondas] similar situations, on a slope
with good runup, jumped on dropping clutch in second and she fired
up almost immediately first attempt..

parked on slopes for next 4 days or so, clutch starting only to avoid
direct drain on battery.. started each time.. then back to starter..
same same similar event months later, same results..
no problem with battery etc since [now 18mths in]..

ive seen many attempts at clutching motorcycles
by many people, some failing while others start
the same motorcycle.. luck, sweet spot, whatever,
but it can be done as i have done it in 2 separate events..

Why is it that you push start a bike in second gear?

I left my key on for a couple hours, ans had to push start it. I couldn't get it to start in second, so I did it in first and got it. Is this bad?

stepho - depends on gear ratios of the vehicle
with other factors such as run speed and road slope
also effecting the process.. a four speed gearbox
motorcycle or car [say] may be more suited for 1st
gear with its ratio being closer to cbr250r 2nd gear..

you want the engine revolving as quickly as possible
in the short time its being clutch started, without
a high 1st gear ratio working against, the engine revs..

just like changing down from high speed to lower gears
may result in locking the rear wheel, similar effect may
happen when dropping the clutch in 1st..
of course its possible to clutch start in 1st,
or in any gear probably, but 2nd on cbr250r
gives the engine a good shot at turning fast enough
and for long enough to allow the engine to fire up..

ratios are a factor, along with slope and run speed..
i used 2nd because ive clutch started other hondas
using 2nd, so used the familiar process here as well..
no doubt on a long sloping runup you could use 3rd..

starting your car is different in that it has heaps more
mass/weight to keep its momentum going once
moving well, plus it will have a certain gear ratio
which is not likely to be as 'high' as cbr250r 1st..

clutch starting is obviously second choice for starting,
but many people have clutch started many vehicles
without causing obvious damage to their vehicles..
[i had a vw 1600 superbug which ate batteries
but otherwise was a very motorcycle-like car
which i clutch started many times similar to
a motorcycle, runup in neutral, holding steering
wheel and open door, jump in, into 2nd, clutch out,
and bobs your uncle]

there are probably fine degrees of 'better'
but no need to worry about it being "bad"
(:

Just for reference. Running the engine without any battery is not a good idea. The generator and regulator electronics are designed to work with a battery load and the spikes you might get without it could easily damage almost any electronic components on the bike. The same goes for jump starting from a running vehicle.

These small batteries will only take a limited number of discharges before they will no longer take and hold a charge, at which point they are junk.

I'm surprised at how people are able to somehow forget to turn their ignition key to the off position... one more reason for not using the emergency engine stop switch to shut the bike off.
