Re: Honda CBR 150 R

No dude I don't think it's normal, In R15 the humming sound is default and it is very mild and it is same in every bike...But in CBR it's more loud(This sound was not there when i bought the bike), I am not saying about the humming during ignition but this sound resides for the whole ride......"Noise from FI is the first symptom for FI failure in cars"..I think this applies to CBR also. But I am not worried since I have extended warranty.

Everytime I check the coolant whenever the engine is too hot (I can feel it throughout my leg) but they will be normal....But as you said the foul smell may be due to rain, Me too thought about that since my radiator was covered with mud during those times...

Hi Alwin, I tried writing about the humming issue to honda but they never replied.

Anytime dude, But I think the lugging is since your engine is tuned to lower torques...Try to change the gears at higher rpms and initially don't worry about the rattle.. (But, I don't have the rattling noise...The machine is soooooo smooth)

Re: Honda CBR 150 R

I am using Honda 10w30. (edited)
Ok will have to try your suggestion. 4 months left for warranty period.

Re: Honda CBR 150 R

The sound is louder doesn't mean it's malfunctioning, the sound is louder during ignition too, not every FI bike has to have the same sound does it? Maybe there is more resonance in Cbr. I have had the sound frm the first day itself, so have a most of the riders here on xbhp. Bike performs the way it's supposed to without any issues. Also, the radiator fan also creates a buzz. I was at long red light a few days ago and I turned the ket off and on again, the FI buzz came but turned off after a few seconds, when I was driving and stopped because of slow traffic, buzz was still there, might be FI, might be the radiator. As long as bike performs well, nothing to worry about.

AAAAAAAALLLSSSOOO,
Please tell me what wax you guys are using, I have zoomed in on Collinite 845. Works both fr fiber parts and metal tank....Although, can't be used on the black matte plastic parts, what do you guys use on those?

Re: Honda CBR 150 R

My cbr is only 1 month and 14 days old but it somehow feels life time not because i m bore with it but because as i now i can feel it. I have ridden it 960 kms now and believe me its the max that i can do in given time because only weekends and national holidays are the time when i take it out for a ride.... a significant ride..... since some of the problems that are being getting discussed are things that i have noticed too in my bike i would like to share my observation....

1: from day one i m getting the buzzing sound from the bike and from this forum only and from my bike frenetic frnds i came to know it was the FIP, which i completely know how it works and all....so somehow... i stopped noticing it .....the sound is ofcourse still there but no way to the extent that i will find it irritating......as per if it is normal or not....i have heard similar buzzing in my frnds cbr250 repsol special addition..... so....for me its normal....maybe either some guys have real sensitive ears or really there piece is faulty and making big buzzing sound.... if they want it to disappear...then mates.....that is not going to happen.


2. abt the gear missing while speeding down...i hve mentioned this before in thread that how i too was facing this problem but now i hve learned how to tackle it....now also i face this problem but very less frequently....what i do is since the clutch play is very large in our bike....don't press the clutch completely while u r shifting down..otherwise u will miss the gears and if tried hard...u will also stuck them......even now when my frnds try my bike for the first time they face gear missing and then i direct them what to do and in small time they get used to it.....i hve two frnds who hve ride my bike ....now n then but they never complained abt gear missing again....so u have to adjust urself a bit for ur baby blade...

3. abt lugging... i too m driving my bike at lower rpms from 2.5k to 4k...say some 50% of the time....but another 50% ...i go higher from 6 k to 8k...i also sometime ride at 6th gear at speed of 35-40 kms at rpm of 3.5k ........now that i have read some really dangerous consequences of driving this low...i m really afraid if i hve done some damage already...and will try to ride more properly...if someone can help me by telling ideal range in which i should shift my gears and speed range in which i should drive n a given gear...from his(anyone's) experience....experience should be of atleast more than an year...with healthy bike to show for it...would be a great help...


hope this helps...

Re: Honda CBR 150 R


About lugging, only yesterday xbhp was showing this tip- "The best cruising speed, primarily in terms of getting the maximum longevity and efficiency from your motorcycle during long distance riding is about 80% of your bikes attainable top speed in top gear. A better measure is to not exceed 80% of your bike engine’s peak RPM in any gear and especially for long periods of time as would happen if you happen to ride continuously at or close to WOT (wide open throttle)." :P
I am shifting right now at 7k above, initially it was above 6k but now I feel engine has become more relaxed as I am taking it to high revs more an more. So tht means around 27kmph till first, and 44 in second. If you follow the 80 percent rule given by xbhp, in first you should be cruising at around 35-37 as cbr can hit 45+ and in second around 56. :P
I think that is too high, maybe this rule is for commuter bikes. My bike is only 240 kms old, maybe the engine will open up more. But still tht is too high.

I don't have an year's experience but anyways, ignore if you want. Read more about engine lugging, google search.

Re: Honda CBR 150 R

What you have quoted in red is purely for the highway, not city. What XBHP meant was:
Say the top speed of your bike is 125 kmph, then you can cruise at 100 kmph all day long without causing harm to the engine. Does it mean one can't ride at 125? He sure as hell can! But not for extended durations.

For city riding, it depends upon the road and the rider, but since 150 is a high revving machine, it be better kept in its proper RPM band, i.e; above 6k RPM.
Regarding gear shifts:

Say my bike makes max power at 10k RPM and max torque at 9k RPM, then I'll upshift around 9.5-10k RPM so that the gears slot into max torque range and the acceleration (pull) is maintained. This is for max performance.

For the mileage concious guys like me, we prefer upshifting at 70% of max power band which ensures there's no engine knocking.

Re: Honda CBR 150 R

I understood wht xbhp meant, I was only extrapolating it to city and every gear after which I wrote it is too high and hence rule is nt applicable to all gears in city, for cbr at least. Also, above 6k is where is cruise in city in first and second on cbr which is like 53%.

Re: Honda CBR 150 R

Mr. Akash Makkar I dont want anyone sympathy.

As i mentioned earlier i did each n every servicing properly . What mistreating ? I shifting gears between 5000-6000 rpm is it wrong ? I also ride my bike in different speed (low-medium-high ) but i facing problem of high vibration and rattling sound from 1st servicing . So is this my fault ?

I changed fuel pump cost 8700/- rs each (3 times) n gear shifter cost 2500/- rs each (2 times ) still same problem occurring . Now this is also my fault ?

I facing rattling sound problem from starting so i showed it to SVC they did all. Tight all screws, use card board to fill gaps, use fevi quick but that horrible rattling sound strike again n again . So this is also my fault ?

After doing all n last no solution remain thr4 i post here . Instead helping me u saying i asking sympathy and blaming on me without any proper reason .

Tell me one thing i mentioned all my points clearly Which point u didnt understand ?

Re: Honda CBR 150 R

Dude, name calling, seriously?Let me break it down for you, you did hard research for 5 months before buying and you still didn't know FI engines make a buzzing sound or the bike is high revving, you complained to SVC who charged you a lot of money for a part tht anyways would have been in warranty and replaced for free, not even once, but thrice, even the gear shifter should have been replaced for free, You tell me. And don't change your statements now, you said you take bike to high speeds and rpm 5 or six times a year! Lol, now you are saying you took it to high during run-in. You dnt even understand what high is fr Cbr, it can go to 11.5 not break a sweat once warm. Earlier, you mentioned high being 7k rpm, tell me 7k high for cbr!Look at yourself before calling others names.----consecutive posts auto-merged-----See, this is what you wrote, 6-7k rpm is high! Dude, think before you write. You varied the speed! hell you didn't, you're changing now, this here makes it clear you don't vary speeds, 7k is medium, not high, you didn't used to take it till here, you said you do it 5-6 times a year!You also mentioned that rattling sound comes at 3-4k rpm, everything is vibrating at a certain frequency, when something emits a wave with same frequency, resonance happens and vibes become stronger, every bike vibrates a certain amount at a certain frequency, it's possible that fr Cbr150r has tht at 3-4k. Rarely anyone rides it at tht rpm long enough to notice tht rattling, if tht is not happening at other rpms, nthing to worry about. But again, you give contradictory statements, earlier you wrote it happens at 3-4k rpm, then you brought tht problem to higher rpms too, it's hard to believe anything you say, you have been victimizing yourself, you wrote twice, no one feels or thinks like me? You wree asking fr sympathy, I am trying to help you!I am the one insisted against advice of at leats three people to not void your warranty and you are ! Ungrateful

Re: Honda CBR 150 R

Are 4000+ rpm pe bike agar old diesel engine ke tarah vibrate n shake kar rahi hai uper se bike main se bhayanak sound aa raha hai to tu kya karega ?

R u maker of CBR ? Can u take guaranty that all CBR are perfect ? No quality issues and other issues in it ?

Honda launch CBR 150 in March . I purchased it at 13/7/2012 . That time not a single review released on net . This ownership thread created at 4/08/2012 means after i purchase.

So tell me from where i get FULL info/review abt new launched bike ?

Re: Honda CBR 150 R

I am done helping you. Decide what problem you have first instead of inventing them, now it's 4k rpm above which your bike vibrates, in a few days, you'll write the bike exploded when you turned on the ignition. Good luck! Let someone else help you, at least thank me for not letting you void your warranty.

Re: Honda CBR 150 R

Stop fighting like kids guys!
Rahul bhai, aap engine oil grade change karke dekho. Put a 10w40 or 15w40 grade oil. Vibes will reduce for sure. Also, get the clutch plates examined as well.
And yes, first of all, change your SVC to a different one.

Re: Honda CBR 150 R


Teri baat samajhte hain. Your only help is Honda SVC. If they do not listen to you, send a mail to Honda 2 wheelers. Escalate and create as much noise as possible. If still you dont get proper help, try help from outside.

Agar phir bhi solution nahin mil raha, either sell the bike or live with it trying to solve the problem for ever.

Re: Honda CBR 150 R

As per ur accusation(Noise equates to failure), my(and other owners of the bike) fuel pump should be kaput long ago! Im new to this FI in bikes but I got this buzz or humming sound for first 2500 kms for the entire time the bike is running but its gone now.

A member here posted that the buzz must be due to higher resonance. So all owners are learning new things.

Re: Honda CBR 150 R

I think that was me. :P

I said might, just in case it's not. :P
