Re: Kawasaki Ninja 250R

So the all new *2018 Kawasaki Ninja 400* is here!!

And thanks to *Anzen Kawasaki Mumbai* I got a chance to try it out!!

So press the link below[emoji652] to find out how this monstrous beast faired in my book!!

Re: Kawasaki Ninja 250R

Guys, Yesterday my bike's rear brake had jammed and later i found out that the disc was too hot.

However in the morning the wheel was moving freely. Have not rode the bike yet.

What could be the issue?

Re: Kawasaki Ninja 250R

Similar thing has been happening with a friend’s Ninja 250. Rear brake doesnt have any pressure. Feels as if nothing happens when you press the rear brake pedal.

Havent found a solution to it. It does sound very danger though.

However, i feel it has to do something with the brake fluid.

Re: Kawasaki Ninja 250R

If brakes are used continuously they tend to seize, so unless you rode downhill with rear brake activated most of the time I presume the reason for seizure is due to caliper pistons seizing, so now would be a good time to overhaul your brake system, and once done make a habit to change brake fluid at least once a year.

Inspect the system for leaks or line bulging, once that's ruled out, bleed the system.

If the issue persists then put load on the pedal overnight and see if the braking is back to normal in the morning.

Re: Kawasaki Ninja 250R

Hey guys facing some issues with the Ninja 250 and would really appreciate some help from all the 250 owners . Have some serious starting issues at time with the bike as in when I click the stater the bike doesn’t start off . The battery seems good as the headlight and the blinkers do work . This has started to happen constantly these days . When the you crank the bike all I hear is a ‘CLICK’ and headlight goes off and then on again but the bike doesn’t start as soon as I push the bike a bit ahead and put it in a gear while in motion the oust start works strange . Anyone else ever faced this issue with the bike please help .

Also if anyone can suggest a good mech for Ninja in mumbai would be helpful

Re: Kawasaki Ninja 250R

How are you sure the battery is good? Just because the headlights and indicators works?

Do you know how much power the starter motor consumes from the battery?

Re: Kawasaki Ninja 250R

Check the voltage of the battery with the engine off. It should read 12.6V or more. If it's less than 12.6V, change the battery. Tighten the battery connectors too.

Re: Kawasaki Ninja 250R

Hi did check the battery voltage on a multimeter which is 12.6 . So don’t think it’s about a faulty battery also the push button works once I roll the bike a bit and leave the clutch in gear . If the battery is faulty it should let the bike crank always . But there are times the bike starts normal and there are times when I have to roll the bike to get it started . Just a bit confused on this .. don’t know if the relay or the starter is the concern here . Have anyone you guys faced such issues

Did check the same with the multimeter the voltage shows 12.6

Re: Kawasaki Ninja 250R

Guys I apologies if this is OT but I am facing similar issue and my ownership thread has no activity, so seeking your help here. It happened just once, but I am worried it might happen again, and I would like to take preventive measures.

So, sunday night I went out to meet my friends and travelled some 10 kms and parked the bike at about 8:30. At 11:30 we decided to return back, I put in the key, the dash came on, the tachometer did its round till 12k RPM, but the bike did not start when I thumbed the starter. Every time I pushed the starter, the bike tried to crank for a second, but then the dash went off and restarted (like it has been turned off by the key and then on again). It happened everytime I thumbed the starter. Then began the diagnostics. My first thought was that the battery died. It has been 4.5 years and battery life is around 5 years. So I checked the horn which sounded strong, clear and loud, the headlights and indicators turned on with usual brightness. No problems at all, but the bike won't crank, no matter what I did. I would go Krrr for less than a second and then the dash would restart.

This was first time in all these years that my bike, gave me any trouble so I was worried. But I was with my buddies so I had support. One of them suggested to use the age old method of pushing the bike in gear and releasing the clutch. I was not sure if it would work on a FI bike, but it was midnight and I had no other option or idea in my mind. So I decided to give it a go, my friend pushed it and I released the clutch in first gear and the bike started and settled into idle as if nothing was wrong. It was really late and the bike was on, so we decided to leave and check in the morning. I went home, parked the bike, switched it off and then on again and thumbed the starter and the engine started without any hitch. repeated it several time and every time it would run like it had been doing for the past years. I was really confused, so I went to bed and decided to check in the morning. The bike started without any issues again yesterday and today also, no problems at all.

Could you help me out please.

Re: Kawasaki Ninja 250R



Check the starter relay and battery terminals. Remove the terminals, apply vasoline petroleum jelly and tighten the terminals..

Also, check the fuse box for loose fuse..

Re: Kawasaki Ninja 250R

Ok sir, will do.
May I assume that the battery is ok for now? Judging only by the fact that lights, indicators and horn are showing no signs of low battery.

In my past experience a battery's life is more or less 5 years. My old splendor, sister's active, family car etc etc, they all start showing signs of battery problems after 5 years (give or take a few months) and since this is 4.5 years old, I assume it might be showing signs of aging. I will get it checked with a multimeter and report back.

Thank you.

Re: Kawasaki Ninja 250R

Life depends upon the load given to the battery. Yes, please do get back and let us know if issue us resolved

Re: Kawasaki Ninja 250R

Battery life is 3 years for a Motorcycle.

Do a load test, Google for my article on Diagnosing Motorcycle Electrical systems, it's on Teambhp, I've mentioned the steps in detail eith pictures of the same being done on my P220.

Simply checking volts won't give you a correct read as surface charge can be misleading, hence why you need to do a load test.

Re: Kawasaki Ninja 250R

Better to change your battery. 4+ yrs is indeed a very good life and i wouldn't advice you stretching it further especially when it exhibits such intermittent behavior. These bikes depend on electronics to a greater extent than your activa/splendor and so you do not want to be straining the battery/charging system or electronics with a old dying battery.
A load test will give you a better idea on the health of the battery (especially on batteries a few yrs old) than just the voltages.
A small example of my recent experience with the battery on my D200. It is 4 yrs old and the stock battery that came with the bike. Over the past yr the bike wasn't as regularly used everyday (used to sit for a couple of weeks unused) A few months ago it popped up the low battery warning and using it for a few km, the error vanished.. but a load test (done at the ktm svc with their battery tester) did indicate that a replacement was required. I haven't replaced the battery yet and had the low battery warning twice since (with the jg error and console/clock rebooting/resetting during a start), which goes off after a few km of riding.. I have been doing some 130km runs on the weekend and this has prevented the warning appearing even if the bike sat unused for 2 weeks (due to the battery attaining 'sufficient' charge on such a long ride)... but when i thumb the starter, i do feel that there is a slight strain from the starter/cranking before it fires up and not a crisp fire up like it usually was.
I know I am pushing it and would be replacing the battery in the next couple of weeks. So I have been carrying a jump starter around in my backpack in case it dies on me.. and trust me it happens.
