Re: Honda CBR 250R

Hello everyone - joined the forum today and my first post goes here. I bought a CBR 250 pre-worshipped bike 2 months back. The riding experience has been nothing short of exciting, as I have had a very long break in riding + still a newbie.



The freedom of movement (compared to a car), the sheer acceleration at signals to get ahead of the crowd and the refinement are all making me grin wide every time I ride the bike.

Unfortunately, I ended up damaging the radiator while doing a pressure wash this week and have placed an order for a new one @ KUN Honda, Adyar. The current one still might work fine, but then am paranoid of any issues in my vehicle. The estimate is 6K and am thinking of getting a general service also done at the same time.

Which A$$ is better of all in Chennai? I guess I heard better things about JSP Honda Aminjikkarai - but that was sometime back. If you have any suggestions for a good mechanic / A$$, please do share.

I am also thinking of installing a radiator guard and came across "Carbon Racing" - just want to check if you have any recommendations on both the accessory and also the vendor?

Quoted your post as I see you are from Chennai too. Please do share your recommendations on service centres etc.

Re: Honda CBR 250R

Parts availability and service easily done in Didar egmore, next would be JSP Honda.

Re: Honda CBR 250R

Then go ahead and buy it. Check the ABS too.

Re: Honda CBR 250R

Ivin, did you check your RR before replacing the stator coil and the battery? Though the SVCs have an extremely lackluster attitude when it comes to inspecting an electrical part, sometimes it can be a faulty RR and oxidation in the pins that might have caused the charging trouble. Now that you've replaced your RR, do check for proper voltage at the terminals of the battery with the engine running at 5000 RPM with high beams on, the battery voltage at the terminal should be 15.5v, and the readouts shouldn't be more than 16 and lesser than 13v at the specified RPM.


Cheers!

Re: Honda CBR 250R


replies in bold. most mechanics talk things they have just heard since last 50 years and make no technical sense.

you blew a 10 amp fuse... open the box. there are markings for each type inside of the fuse box lid. do you have any accesories conencted to the motorcycle ?
extra horns or auxilarry lights ?
besides the starter motor which is a 25 amp fuse rest are all 10A. also there will be 2 spare fuses put across vertically on the sides.

1.how old was the battery ? 25k too early for stator coil to go.
2.once the cone set change is done tighten it a bit like 2mm or so after a few days. it gets loose which is normal however if you leave it like that the play will kill it again shortly.
3. shell ultra 10w-40 works best. tried the new ultra 15w-50 as well but did not like it.

what do you mean by damaged the raditor in pressure wash.. mine gets pressure washed directly on the raditor every 15 days and been like that for 6 years..
did it leak ?

Re: Honda CBR 250R

The silliest mistake one can make...
I applied WD 40 on both front n rear breaks. N now feeling more foolish than regretting abt it.
Although gave bike n service n the mechanic told me to drive for sometime. It'll become normal after some use.
Also read at some online forums n they suggested to use sand paper. But heart says to no more experiments.
N in the end if nothing works then I've to replace the break pads.

Re: Honda CBR 250R

pads do get glazed with time and heat. nothing wrong to rub them a bit with sand paper to get them to grip again well...

Re: Honda CBR 250R

WD 40s aren't meant to be used on brake pad surface. Though they can be used to clean the caliper when they are overhauled, any solvents be it petrol, diesel, polishes let alone WD 40 when comes under pad surface or rotor. The brake fade you observe is only temporary, and once the brakes are warmed up and hot, the feedback gets back to normal. If you feel you've lost feedback, perhaps then you can remove the pads, midly rub them with sandpaper and then install them back.

Next time, if you feel to clean your rotors, use a brake specific cleaners such as STP, they clean yet vaporize instantaneously leaving no residue as a result the rotors and pad get cleaned without any loss of feedback. Been using them in my drum brake equipped bikes and are very much effective.

Re: Honda CBR 250R

Thx a lot guys. I think I should have 40-50 kms ride n then should check the result. Now break is performing 30-40% of its full potential. Not confident enough to ride in city.
But a big lesson learnt.

Wipe off with alcohol.

Re: Honda CBR 250R

Hello experts, need a small guidance. I know this topic has been discussed a lot here but still I would like to add my personal experience there. Next month I am due for service and need to replace engine oil. After my last service with Honda synthetic oil, the bike was good up to 3k, later I was seeing very black color oil and slightly higher engine noise. Later I have changed the oil with a local garage with motul 20-40 synthetic oil, I didn't get right grade. Later bike was way better than Honda oil, engine was smooth, I can see more torque. With Honda oil, I can use 6th gear only once I reach 59+ speed but with motul around 53+ km speed bike was gaining enough power, I mean no stress to engine. Now it is close to 3.5k on motul, very recently noted a slightly higher engine noise and roughness from engine.

During next service I am planning to change to motul synthetic 10w-40 or I am not sure whether motul has 10-30 synthetic oil. I always read that shell ultra helix will go very good with Cbr but the local car garage, I heard like shell is not doing great these days and I trust those guys.

So what's you suggestion, do I need to stick to 10w-30 grade. With motul 20w-40 grade, I saw like low end torque is higher but bike high speed performance was not good. I mean once I reach 100+, I feel like I have reached very high speed.

My common observation is, bike engine showing roughness once oil reached 3.5k range. So if I am going with Honda, I am planning to collect a seperate bottle so that I can change oil at later point.

How's yours experience with engine oil? Are you using up to 6k range? Is there anyone who still using shell ultra helix? Motul 10-40, will it suit Cbr?

Honda CBR 250R

This topic has already been discussed a zillion times i guess.
It is all about your personal preference whatever oil you use. Usually altering the recommended grade is not a very safe idea in my view, yet there are a lot of people who have experimented with different oils and grades

Coming on to your query, there is no direct answer for this.
Since, i have used Honda throttle, Motul 7100, Shell advance ultra in my bike.
Below is the summary of my observations-

Honda throttle - fine for normal city use. But after 2k on odo it starts giving up gradually.

Motul 7100(10w40) - a good oil and in my experience easily lasted more than 4k km on odo. This is the most performance oriented kind of oil out of all three. You will immediately realise that engine is more willing to revv but less smoothness compared to shell. Prefer this if you are someone who likes to wring the throttle more often.


Shell advance (10w40) - most praised oil on this forum when it comes to cbr. And truly the smoothest of all but performance is less aggressive as compared to motul. Best option if you ride sedately and want better oil than Honda throttle. Also lasted more than 4k easily.

PS it is shell Advance ultra that you should go for. Shell helix, which you stated is a car engine oil. Avoid it.


Also keep in mind that the recommended grade is 10w30 which is not available with motul and shell so you can go for 10w40 for both of them. As per my knowledge there is no harm in going for 10w40. Cant comment on other grades though.

Re: Honda CBR 250R

Helloo friends,
First request is not be mad at me for repeating this oil topic.
After a lot of research and ground work,test rides, on choosing a motorcycle to rejuvenate my riding skills, i shortlisted the cbr250 r.I was almost close to booking the new one, when a casual look in one of the sites grabbed my attention on a used CBR-2013 dec model ,clocked just 15000kms on the odo. Quickly connected with the seller, found that everything with the cbr was genuine, and yes i loved that honda ''whine''. The bike was like ''new'', waiting for me.Without thinking much, i grabbed the bike and here iam with a few questions.

1. Oil has been changed just last month by seller and run close to 800 kms after that.He has no idea what grade but i believe it should be 10w30.

The manual does say the grade as 10w30 and MA spec, but not whether the oil should be mineral or semi synth or full synth.
The honda website shows the fully synth(throttle oil) which is API Sl and JASO MA.

Now, there is a servo 4T synth 10w30 oil - a synthetic blend-API SM,JASO MA2(higher than honda-but still synth blend). As far as i know, the honda fully synth is definitely not a PAO base or an Ester base(ie-not group 4 or 5).It would be a group 3 oil, which actually are not pure synthetics.Basing on this fact and the manual's information,can i use the servo 4T synth??

2. Just a day before i downloaded the manual from honda site, i happen to get a link of cbr 250r manual in which there are 2 grades(10w30 and 10w40) specified,out of which you can choose the one as per your location's ambient temperature. The one i got from honda site has only 10w30, but the arrow extends beyond the 30 degree range if one would have noted.The lower limit also crosses well below zero!! for a 10w oil.

So, has anyone tried the 10w30 servo 4t synth? I mean is it really worth trying?

3.What is a good shift rpm for the cbr 250r? i Generally try to keep the engine around 5 to 5.5k. If it down below that, it seems like individual struggling strokes.At 5k and above, the engine sounds like a hum and is able to take the next higher load.

4.Above what rpm is rapid throttle opening recommended?

Appreciate your expert suggestions..

Re: Honda CBR 250R

PAO are the normal full synthetic oils you get. Usually oils are categorized in groups from 1 to 5 with one being the least refined and the five being the best refined with man made additives added or also known as PAG. Now, it's usually an inflated term for a lingo, as it only confuses people. Synthetic and Esters make life easy, isn't it.
Now, to our topic, 10w30 is what Honda recommends, while at the same time if you inspect the manual, the grades go thicker depending on the riding condition, i.e. climate. And for varied indian conditions, 10w30 is the recommended oil as per the recommendation, unless the bike is ridden in a high ambient temperature setting, w40 is recommended. Irrespective if a given oil is PAO or PAG, the right grade and the right drain interval plays a vital role and helps keep the internals healthy.

The shift RPM that you practice is a good RPM range and where the little blade feels happy and peppy. Rapid throttle opening can be opened above 4k RPM as sometimes sudden throttle opening can flood and stall the engine momentarily, gradually open the throttle all the way up to the desired RPM.

Hope you've invested in a proper set of riding gears, helmets, gloves, jackets. Ride safe!

Cheers!
