AFAIK in the old vehicle like Bullets (which had engine kill switch in 90's), RTZ and all just break the power line to the coil. (I am not very sure).

Where as the latest bikes break the power from CDi directly. Emergency in the sense when you have a fall and you wont be able to reach the key and engine is still running u can cut off the engine with engine kill.

I had read this in some post in xBhp where the discussion was more on FZ and in FZ manual it was much clear. I will try to find that document over the weekend and upload it.

^^The ignition switch cuts off power to the ignition coil and CDI. But, the engine kill switch just shorts the pulser coil signal to ground. Without any timing signal, the engine stops. The CDI, ignition coil however remains powered. So, it may drain the battery in the long term. (On a DC powered ignition system only)

I think the 'emergency' would be a situation where you need to quickly switch off the engine without taking your hand off the handlebars. What i can think of is, eg1: brake failure, you can cut the engine without removing your hand and in gear this would slow the bike. eg2: throttle got stuck. Im just guessing.

your guesses make a lot of sense. I have a P180UG3 and I have been using the engine kill switch since the very first day. It doesn't kill the engine guys!

Don't worry!

I have read in the p180 owners manual that "The engine kill switch is for emergency use only. Move the switch to off position in case of emergency."
What do you have to say??

1) (Sarcasm) If you use it frequently, it might break and get stuck in OFF mode.
That shows Bajaj's trust in their switch gears

2) Switching of with igni. key switches off every thing, but Engine kill switch switches off just the engine, not the electricals eg, brake lights, horn, indicators and in case of FI, DC bikes , fuel pump, H/L, pilot lamps etc

So at signals use it w/o any worries.
but when chatting with a long lost friend who just met you in parking lot, use ignition key.

Then why do the manufactures put such a feature on the bike if it really harms the engine...

Excellent point! Why would they do that?

For sure the engine itself is not affected/damaged whether you use the kill switch or turn off the ignition key.

In effect, as far as I know, they both kill the engine in the same way, by grounding the ignition to kill the spark. The difference is that the rest of the electrical system is still powered (lights, horn, injection pump, etc) when using the kill switch to stop the engine.

Only thing of course is that if all the lights are still on and the engine isn't running then the battery is being drained and not recharged. But overall I'd say that the electric starter motor is more likely to drain the battery if you use it every time the lights go green.

Kill switches do fail quite a bit, at least mine have done, but it's always been down to dirt, or corrosion of the contacts, inside the switch. With care and a bit of sandpaper they can be easily cleaned.

If the switch is not to be used frequently, then the manufacturers would have given it below the saddle

The main purpose of giving it near your thumb-reach is to use it often in stop-go traffic. IMHO it will NOT cause any harm to the engine.

Guys after reading this thread now i m using that switch.
Giving my trust,hopefully it 'll not kill my engine!!

**Stark23** · 02-10-2011, 12:10 AM

Whoa! I use it infinitely! I mean whenever or wherever I stop my bike first I use the engine kill switch then turn it off with the ignition.And before starting the bike when the self check completes then I turn the ON the kill switch and then drive the bike.

So is it aite ?

there is absolutely no harm in using engine kill switch at traffic lights or as frequently as you desire....i m using it from last 4 years to turn off the bike every time....i only use engine kill switch.

what is the actual purpose of engine kill switch?
let me answer it....why do you think some cars come with engine start switch, while same can be done with key also, the answer is ---

Convinience, and
To save time.

and these are the exact reasons for giving engine kill switch. it comes in handy specially at traffic lights as your bike does not have to go through self check mode and it is handy too...u do not have to move your hand from handle bar.

it is a complete myth that it can harm your bike in any way or it is meant to be operated only in case of accident. it is also a myth that it can drain battery because your battery will be drained only if you left the ignition on for several days or weeks.
