Re: Honda CBR 250R

CBR has very mild vibes at that particular RPM, but it isn't bothersome per se. A good set of gloves and helmet should help negate the vibes issue. Some amount of vibes will always be present.

Re: Honda CBR 250R

Shift at 5000 or 4000rpm bike needs to be right in the middle of the rpm for the Sweet spot.

Re: Honda CBR 250R

If I buy a CBR 250 R BS4 now, will there be any spare part issue for the next 10 years? Or do you guys already have spare related problems?

Re: Honda CBR 250R


No chance of spares issue. Just for easing your mind every manufacturer must supply spares for vehicles upto 15years(not entirely sure if its more) post the date the model production is stopped.
Even considering the worst case scenario you should be covered. The CBR250R is not a India specific bike so parts will be easily available from outside sources also.

Re: Honda CBR 250R

Check your Engine mounting bolts and re-torque them...This may help.

Re: Honda CBR 250R

Hi guys, I've been facing a persistent issue since I bought second hand 2018 CBR250R ABS which had run ~7500 KM when I laid my hands on it. Now it has run ~11,000 kms.

First sound: It makes mild krrrrr ( ~50 % of the riding time ), rattling / resonance kind of sound noticeable after speeds of 30, 40 kmph which comes and goes intermittently.

I ignored it initially and thought to be some kind of rattling sound from the fairing. My trusted mechanic also didn't pay much attention to the sound.

But yesterday I insisted him to check properly and fix it, after listening to this sound more carefully, he guessed it to be coming from engine head, related to valve clearance. But he's not sure and suggested me either to take it to good ASC for second opinion or keep on riding until the sound gets more prominent.


Second sound: But sometimes ( <1% of the riding time and after riding for considerable amount of time ), I get bit loud noise ( khat, khat ) from the front area (like a stuck stone or a loose nut in a tin can) when I accelerate the bike within a gear on a slight incline. It's very difficult to predict the onset of noise otherwise I could capture the sound in my phone. Sometimes this khat khat kind of sound is mild and sometimes it's quite loud and feels as if something would break and fall off from the bike. This sound lasts for ~5 - 10 seconds and generally comes inbetween 3000 - 4500 rpm while relaxed riding in the ghat roads.

There is no strange sound at idling, fuel efficiency and power of the engine are quite good.

What can be the issue? Can the 2 sounds be related to each other. Can I keep on riding the bike like this. I'm scared of taking it to Honda ASC and leave it to their hit and trial methods.

Re: Honda CBR 250R

Went to showroom today. Both CBR 250R and CB 300 R are not available now. Honda also responded the same. CB300 R will be manufactured in India and will be relaunched in 2021.

A bit off topic:
The sales manager said they have their test drive CB300 R for sale. It's 1170 kms on the ODO. They are asking 2.6 lakh with all taxes included. Is it a good deal? Also, as this is a test ride vehicle, what all things might have worn out? The piston and cylinder wearing can be abnormal?

Re: Honda CBR 250R


Yeah, that was expected being the BS4 deadlines already right in front of us.

Test ride bikes are always a gamble. Most of the time the bike is handled by a huge number of people who may or may not know how to ride a bike properly, moreover all the antics are done on this bike itself.
There is no guarantee of proper oil change intervals and there is this epidemic among many Indian mechanics that oil filter need not be changed, I myself had to fight with mechanics during my Pulsar days to get them to change it.

Then many times proper fuel level or good fuel is not maintained on these bike and fuel level is almost always less, so chances of fuel tank rust/ fuel pump wear and tear issues are also higher.

Now since it is a Honda engine it can withstand quite a lot of abuse , and since you say its just a smidge over 1k run the chances of too much damage is also less.
I am not sure about the price, I always felt they were grossly overpriced and feel the same with the prices quoted here too.

Ride the bike, check for damages negotiate on the bike price. IF the bike rides well then might be worth it. But i'd suggest to go fishing in the 2nd hand market for CBR250R, I am pretty sure you would find a few good examples if you take time and look.

Re: Honda CBR 250R

Thank you for this input.
I was thinking the same about price and getting Used CBR 250R. OLX has good number of listings, but finding out something without any major damage or false ODO is the problem. Anyway, I'll dig a little deeper into it.

Re: Honda CBR 250R

Hey guys

I want to change my CBR250 fork oil to a higher grade (20W motul fork oil) for better handling, default is too soft front. Recommended grade is 10W in service manual. Can 20W be used in CBR forks without any issue?

I guess I would need 2 bottles @350ml each

Do I need new fork seals or the old seals can be reused?

Any other suggestion or advice please?

Re: Honda CBR 250R

@krish2778
Regarding used CBR 250R, I read the thread by @shv18 which has almost all the details to be considered while getting a used bike. However, I don't have a mechanic to inspect the bike as I live in Hyderabad, and belong to Kerala. In this case what can I do? Any suggestions? Thinking of taking the bike (once I find one) to nearest honda service centre, but don't know if they will be honest about it.

Re: Honda CBR 250R

A basic list of items should be good enough.
Any engine noise would be apparent enough. The CBR sounds buttery smooth on idle and blipping so if any funny noises are there it would be very evident.
But one thing i would suggest is, any bike you go to look at in person, be very specific to ask them that you want to hear it on a cold engine. So essentially the bike should not be warm or hot when you are going to listen to it the first time.
Most of the sound vanishes once the engine is upto temp.

Main things to look at are rust in and around frame / rotors (not surface, but mounting points) / frame / chain.
Look at consumable life like chain sprocket, brake pads, tyres
Listen for tappet noise(sewing machine like sound is what you need to look for, if its present then the valve clearance needs to be set.)
Ride and see for alignment issues, clutch slippage(gives an idea of clutch life) and in general the ride should be vibe free unless you are in the 3-4k rpm range where a slight vibe is always present. Also look for the radiator fan kicking in, a CBR that is running well will never cross 3 bars in the console indicator.

Also, Shiv has prepared a wonderful thread which you can look into to get the bike back to factory condition if at all any small issues are there.

Re: Honda CBR 250R

Thank you, krish. I'll look into options and get back when I stumble upon something.

Re: Honda CBR 250R


been using motul 20w for over 6 years now. stock used to be 5w maybe now its 10w for CBR.
the stock quantity as per service manual is 331ml per fork.

get a motul 20w bottle , well sealed and use one bottle each fork. accounting for some wastage you have close to 345 ml each fork.
the rebound will be better. if you want stiffer suspension get spacers made from old used splendor forks. been using custom spacers and motul 20w for a long long time now.

where in hyderabad ? am in hyderabad too. PM me. lets talk.

cbr is known for rattle and slight vibes at 5500 rpm however it should be something thats numbing your hand. check below
chain tension
chain clean and lube
air pressure.
fuel quality.
idle the bike for 60-90 seconds at cold start ( have seen this multiple times without idling the bike does run harsh sometimes ).

Re: Honda CBR 250R

Just to add what fellow Bhpians have mentioned. I am using the 20w Motul oil on my CBR and the front end feel is much better. The stock oil is 10w, and the correct quantity is 331 +- 10 ML. I've used 350 ML per fork and so far so good. Make sure while pouring oil, the fork is pumped well to remove residual air, so that it helps prevent air pockets. As a thumb rule, always replace fork oil seals when replacing fork oil. In case, the seal leaks, then you are in trouble. Always replace fork seals as a set when replacing fork oil.
