Re: Honda CBR 250R

I got an Amaron ProBiker 9AH for 1800 in Kerala. The guy had to file away part of the clamp to fit it in. But it works fine without any issues- benefit is that I can use the horn for longer time without fade.

Re: Honda CBR 250R

I considered doing the earth wire mod, having read shivs thread multiple times. However, I have full electrical power when the random stalling happens. And the bike invariably starts again, without a problem. So I've kept the earth wire mod as a last resort.

The indicator switches get hard to operate after a while. Pouring oil in them makes them smooth again.

Re: Honda CBR 250R

Then this is similar to the issue I faced - rust and fungi in the wiring assy, from the ignition coil till the battery. I had to replace the rusted part and cleaned the fungi infested part.

Re: Honda CBR 250R

OK, here is another test result, this time about the Honda 10w30 mineral engine oil.

A couple of guys had advised against using mineral in summer stating that the oil would not be able to control the engine heat. So I ran my bike for an hour in traffic, to find out if the CBR overheats in Chennai summer.

Ambient temp : 34*C

Petrol : Shell normal

Distance : 30 km

Engine oil usage : 600 KMS so far on the Honda 10w30 mineral.

Usage : First and second gears only. First was used till 30 kmph, around 6-7k rpm. Second was used till 9k rpm, around 60-65 kmph. Bike was revved till 4k rpm when idle in traffic.


No overheating detected. Bike rode smoothly, and temp gauge never went above three bars. Fan was on for most of the ride.

Re: Honda CBR 250R

I'm still confused over synthetic and semi synthetic....

Re: Honda CBR 250R

Go for fully synthetic bro. I changed my FS Honda Throttle at 6k kms, no issue at all. I just used mineral for a trial. Next, I'm gonna try Shell Advance 10w40, or the Gulf Pride 4t Plus 10,000 kms oil. I emailed gulf about their oil last week, but didn't get a reply yet.


Just remember that you will lose mileage and top speed slightly if you go for a 40w oil.

Re: Honda CBR 250R

I'm using semi synthetic at the moment, I change my oil every 3000-3500km , before this was service centre oil where they use castrol, I think from next oil change I'll try motul fully synthetic, I have a doubt is there a problem from changing from semi synthetic to synthetic ?from usage terms, its been 1500kms, and bike feels fine, its pretty smooth for me, not faced any issue, maybe a bit if heat but negligible but being in Chennai that's normal, my temp gauge has never ever gone above 3 bars.

Re: Honda CBR 250R

I was having the same problem itself, riding around casually on 2-3 gear at 3-5k rpm and suddenly thn bike kills itself, one push to the starter and it starts without any problem. It used to happen likr once every week or so, but later i tried that earthwire mod and to be honest it actually didnt work that well right after doin it[emoji29] but slowly after a month or 2 the i had no such problem again and the bike now doesnt kill itself anywhere. Idk how it happened and if because of earthwire mod then why after so long and not right after.

Re: Honda CBR 250R

Absolutely no problem I had faced when changing from FS to SS to mineral. Advantage of FS is just longer life. The manual does not forbid us from using SS or mineral, so its up to you to experiment and choose which oil suits you.

Funny thing about the 5 k rpm vibes is that it goes away for around 1k-1.5k kms after each oil change, then reappears. If I top up the oil, those vibes then disappear for another 500 kms.

Re: Honda CBR 250R

Hey guys,

As day before yesterday one of my friend bought a used CBR250 Repsol Edition late '13 model, the bike costed him around a lac and has done just above 14k kms.

So as i had went for Mumbai-Bangalore-Mumbai in under 30hrs ride so i couldn't go with him to take the delivery and as he have no idea about servicing or any other thing. He got his bike serviced by a local mechanic near his place.

Things he did:-
1.Oil and filter change to motul idk the name of the oil but it costs 550rs per ltr and golden in colour.

2. Both Brakepads changed but not genuine Honda but some locally manufactured ones 1000 bucks for both ( very cheap compare to 3000rs + for genuine honda ).
3. Chain tensioner changed bcz of tick tick noise
4. Coolant top up.

So after all these things made, he calls me up saying " dude i did all that u told me to but by some local mechanic but the bike is heating alot". Now after i reached back to mumbai yesterday 6pm i directly went to him and saw the bike clean and polished it looked soo good [emoji7] . So yeah he explained to me whatever happened and then we started the bike, it was cold he started it up and within a minute the temperature bar reached 3 points and we went to that mechanic to explain it him which is not more than 500m away and no traffic. As we reached the fan started up and was on for like 5-6mins.
I asked the mechanic to flush the coolant and put another new one which he did but still the bike kept heating alot ( it doesn't go beyond 3 points )

So my point is what could be the problem? Why is the bike heating so much?

Sorry for such a long story [emoji43]

Re: Honda CBR 250R

Seems okay to me.

Too many posts on engine oil. Read the manual. Nowhere it says FS, SS, or minerals! Just stick to grades and viscosity.

Re: Honda CBR 250R


There are 2 tricolors.
The original is the Pearl Heron Blue color for the 2012-2013 models. It was changed to Pearl Sunbeam White - new tricolor. This was applicable across all versions, both international and national. The newest sticker jobs are not found in the international versions of the CBR250R.


1) Why use aftermarket brake pads? If one is willing to spend 1L+ for a bike, why does the extra 2K matter (which might be a life saver)
2) If you read the thread, you will find the temperature bar goes to 3 bars and stays there for the CBR250R. You need to bother about high temperature only if it goes above that.
IF the ambient weather is hotter, you'll feel more engine heat, simple fact.

Finally, you should only use genuine Honda blue Type 2 coolant as other coolants might have materials that damage the radiator seals in the long term. Also, while replacing the coolant, it is imperative to do it in the proper manner i.e. top up the radiator, turn on the bike for a minute to let it circulate, and then top up the lower reserve tank up to the "Upper" level indicator.

Re: Honda CBR 250R

Hi Guys,

I faced a very peculiar issue today with my CBR.

I in fact had to pinch me to check if this is real or not, the following are the things I did exactly from yesterday night.


1. Yesterday I had a ride of around 35-40 kms with 2 stops, and the bike behaved normally.
2. Night(around 1 am) I used the bike for drop a friend to his home which is a 2kms ride up and down. Did not observe weather the fan kicked in or not.
3. Today morning started around 11:30 am to office, stopped the bike in 750 meters for a juice break(fan did not kick in for sure).
4. Had ridden for 5-6 Kms with pillion rider, then dropped him and continued to office riding single for 30+ kms(mostly with speeds around 70-90 Kmph in highway). Fan must have kicked in for sure but had not observed it closely.
5. When I was about the part the bike in the multi-level parking in office, I observed that the fan is at full speed. As usual I used the engine kill switch to stop the engine(and fan too), but the fan was running continuously.
6. I tried toggling the engine kill switch to on and off position couple of times to check if the fan is cut-off as usual, but it did not.
7. I have turned the key to off position(and later to pulled the key out) and to my surprise the fan was still running. This is where I was not sure if am dreaming or not, but what ever I tried the fan was continuing to run.
8. I finally removed the fuse of the fan from the fuse box, and finally the fan stopped completely.
9. Then I removed the negative terminal from battery, replaced the fan fuse locked the bike and came to my work place.


I know I need to get it check at ASC, but I cannot do it today or even this week. Will definitely visit ASC by next week.

In that few minutes, I managed to observe that engine kill switch is functioning normally(except turning off the fan) like fuel pump priming, self starter button is not cranking when the switch is in kill position. And the ignition key is working normally(again except turning off the fan) like console showing its self check, lights/headlight switching on when the key is in on position.

Its been almost 6 hours since I left the bike with negative terminal of the battery disconnected. What are those things that you guys want me to check before I take the bike again(which is around 7:30 pm).

Although I started the bike and I found no issues anywhere else except the fan issue, so I guess it should be rideable till its next ASC visit.

Re: Honda CBR 250R

Thermostat wiring or fan wiring is shorting again and again , this is causing intermittent problems. Check the wiring , it must be either cut or shorting somewhere.
Also swap thermostat / remove it and try whether it is working.

Re: Honda CBR 250R

Thanks for the words, but my question is more on why the fan kept running even when the ignition key is removed from the bike??

And do you have any pointers on where the thermostat is placed in CBR 250?
