Re: Honda CBR 250R

In some motorcycles the ground is coded black, not the case with your motorcycle(obviously) but you could confirm by checking continuity between Black's and chassis, there shouldn't be any.

Re: Honda CBR 250R

It's time for new stator. Though it can be checked for continuity/resistance and getting it patched for the time being, eventually frayed wiring would lead to poor electrical connection which in turn can cause shorting and cause overheating of the RR and fail. It's advisable to replace the stator coil assembly. And yes, three phase stators have three wires coming out of the stator and single and two phase have two wires. Most stators have a solid yellow wire for all three coming out, but some do have color coded. If it's color coded, I'd suggest you solder the wires and then tape them to make sure they don't short.

I'd definitely suggest you to replace the stator.

Re: Honda CBR 250R

True about that, if you're planning on using the old stator then anything which doesn't involve heat shrink sleeves and soldering is a bite in the ass when you least expect it.

BTW, how expensive is the CBR250R stator? If nothing you could take out the old stator and rewind it and use fresh wires if all goes well you get better output and you learn a new skill, if not then you're anyway getting a new stator.

Re: Honda CBR 250R

Indeed. A faulty solder and you're gonna fry the RR, but that's one. The cost of the CBR stator is close to 2700 if my memory serves me right. Rewinding can be done, but not unless one's sure of what he does. It's better to get it replaced, totally for peace of mind.

Re: Honda CBR 250R

try talking to a svc or a local mechanic who probably might know how to put it back together. A good soldering connection with proper insulation and you should be good to go. I don't see a reason to replace or rewind the stator since it is just the connection wires and not the actual winding that is damaged.
Pull out the cbr workshop manual (it is available online) and check the wiring diagram or pictures for reference and try to get it fixed. Even better if you can get hold of an old stator coil and maybe 'transplant' the wiring part of it.
Just needs a bit of effort if you want to save some money and still have it running well.

PS: I doubt if it were the rats.. maybe some miscreant who cut em off, i mean all the wires fully cut..

Re: Honda CBR 250R

True about the replacement bit, I would've gone about it any other day. But recently got my mind wrapped around coil rewinding and DC conversions, hence that's coming out in my replies.

Re: Honda CBR 250R

Yep its ₹2774 for stator and another ₹51 for crankcase cover gasket.

Re: Honda CBR 250R

Hi Everyone,

Recently I started digging this thread as I am planning to change my ride. I have two options in my mind one is dominor and the other one is CBR 250R. Saw so many videos in YouTube about dominor and it has many pros wrt value for money. But still my mind is not inclined towards it may be becaus of it’s engine vibration issues and not pillion friendly and at last it’s coming from Bajaj so thinking of reliability issue. Now let me tell about my experience with CBR. I have taken my friends cbr for a trip to chennai from bangalore and it was one awesome ride and fell in love with this machine.

1. I used to do long tours at least once in 2 months.
2. Pillion comfort is important
3. Reliability and refinement
4. Want to cruise constantly 110+ in highways without any stress for rider and machine.
5. Budget is 2L.


These are main things I’m considering for my upgrade.

My question is does spending 2.4L for CBR(definitely ABS version) now is worth? Is there any other competitor for this machine now? Some are telling it’s not worth to spend this much money now for CBR!

Can someone please help me with the confusions I have?

Thanks in advance

Note: I have bullet standard 350 now and I did some long tours with this machine clocking 27K kms in 2 years. But I feel I took wrong decision buying this and I’m not confident to go to tours in this machine with pillion due to many reasons like tube tires, less power , etc...

Re: Honda CBR 250R

Take a long ride of the Dominar and see if it suits you. Also try the Apache 200 RTR. It can do 110 all day afaik. The CBR is good, but the premium on ABS is too much.

Honda CBR 250R

Thanks for your help buddy. Currently, i am reluctant to change the stator coil. Although i am planning to rejoin those wires along with proper insulation for each wire. A local mechanic also suggested the same. If i notice anything unusual after joining them, i ll go for stator assembly change without a second thought.
My only concern was that those three black colored wires having continuity in them can be rejoined in any pattern. Since it is impossible to know which of the black wire on one side has been snapped off from which black wire from another side.



Tinkering with the coil is something that i would strictly like to avoid bro.
I have the workshop manual with me. Ill try looking into it and see if i can find out anything from it.
And yes it has been done by rats and rhodents only because i always park my bike inside my house so there is no possibility of anyone coming in.


In case of rejoining, there is no point in missing on insulation. I ll do proper insulation using weather seal tape. I am just worried about those three similar colored wires. Rest of the wires can be easily rejoined due to different colors. That’s pretty much it.

Re: Honda CBR 250R

My thoughts:

1. YouTube videos are crap, plus with the Internet being dirt cheap in India the number of people posting bullshit is on the rise, the viewers are no better, which is why idiots like Rachamalla and Nikhil have many folds the number of views than someone like Ari Henning, the funny part about this being that Ari can build a CBR250R from scratch whereas the manliest thing you might see the formerly mentioned idiots do is to connect an Aliexpress sourced OBD sensor to their motorcycles.

2. Reliability is a subjective term, as far as my needs i.e touring go anything with pricey spares that are hard to source is less reliable, because of the potential downtime the issue poses. As far as components used in motorcycles Honda and Hero Honda use the most expensive components in general but that doesn't mean that their motorcycles are trouble-free, as every part has a service limit after which it should be serviced/replaced and this depends on the way a motorcycle is set up, anything aggressive as the Pulsar's, Duke's and RTR's and you observe a shorter change interval compared to the lazily tuned motorcycles such as the Unicorn's etc, this doesn't mean that one is more reliable than the other it just means that it is built a particular way that's all. Not leaving that aside there are some components that uniformly face wear i.e the fueling components, control cables, clutch, suspensions components etc, and for anyone who is into touring should change these periodically to avoid an unexpected mishap en route so in that front a Bajaj is practically more reliable than any other motorcycle offered in the market if the intended purpose is reliably covering miles.

3. Pillion comfort is more or less the same on all modern motorcycles, and believe it or not for a veteran motorcyclist, the overall ergonomics is a matter of concern rather than seat foam density. so you could try researching on means to improve the above as per your tastes.

4. Both motorcycles being single cylinders and one being choked leaves no doubts as far as refinement goes, but considering the distance you do it won't make a difference at all, if it does then you need to rework on your mounting skills. What you should be bothered about for a fact as I've mentioned earlier is ergonomics and usable torque, the Dominar offers more useable torque but at the cost of some buzz, and if you've not already noticed, the CBR250R lacks decent oomph down low which is noticeable when you are climbing an incline from standstill with a pillion.

5. 110kmph is not a matter of concern for anything that has over 200cc's irrespective if the state of tune or gearing. As far as stress is concerned I would have advised against anything that has clip ons' but since your travel range is around the 500 km's a day mark it won't make much of a difference.

6. For 2L you could get yourself a Dominar, but for a little more you could get the CBR250R because;
a. Its an International machine meaning the workshop manuals are easily available online, same goes for aftermarket spares.
b. The motor is designed to be robust and has contingencies in place for a few weak spots common to liquid cooled motorcycles, so if something goes bad then you can at least limp back home.
c. The state of tune, being subtle you won't have to be bothered about replacing the head gasket as frequent as you might on the Dominar, and given the right amount of motivation she's got a lot of oomph up top for fun, though periodic replacements are a pain as Honda spares are pricey and harder to source in comparison, and contrary to popular belief there is no difference in quality.

7. Fact be told, tubeless tires are a mere convenience but as far as reliability goes nothing beats tubes and spokes considering Indian road conditions.

8. Consistency matters more than power on paper, presuming that you ride 500 km's a day taking average speed to be 60kmph you would be riding for about 6 hours, so make sure to choose a motorcycle you would be fine with riding for 6 hours at a stretch.

So do think a fair bit before commiting and ride safe!

Re: Honda CBR 250R

Do you often carry spare tubes and tools to fix punctures on your tours?

Re: Honda CBR 250R

Hey everyone, I need to know what are essentials needed to maintain this CBR.

It's been a week with my partner; done 500kms so far.. I'd be happy to know from experienced ppl so that I cud avoid common issues.

And also chain lubes, slide protector and riding gears which would u ppl suggest. Let me know.
And any meetups planned for CBR group rides in Chennai, I'd be interested.

Re: Honda CBR 250R

I am not asking you to tinker with the 'coil'. If you look at the actual coil you will understand what i am saying. You do not have to touch the winding.
You at least need to open stator side case and look at the coil and try to fix the wiring by looking at wiring diagram or another stator or probably someone on the internet has posted an informational pic/video on this. Taking the stator out will be easier for you to fix it than trying to solder the wire while in place since the cut seems to be at the end with hardly any space left for soldering them.. now that's tinkering without knowing where the wires go and is risky.

Re: Honda CBR 250R

Quintessential thing to maintain a CBR or for that matter any motorcycle is dedication. The most important deed to a motorcycle would be a thorough wash. The rest as you've tabulated follows in the maintenance table.

You can use ROLON, TriboCor and Motul chain lubes that are available off many e-commerce sites. Secondly, for riding gears, you can post your queries in the dedicated riding gear thread. There are lots of Indian brands offering riding gears, more details will be communicated in the dedicated thread.



Generic frame sliders for CBR are available online. Though there are a vast variety of brand specific sliders available abroad, purchasing them via e-commerce here in India is an expensive affair. You can perhaps try Aliexpress, they ship to India and do have a quite a lot of slider variations and designs. Do give it a try.

Cheers!
