Be the vehicle porky in the Dry/Kerb weight department (As a dry weight penalty will be obviously carried over when you tank up and load up the consumables), the effects will be:

1). Since the engine would lug more weight, one would see slower response to changes in direction/speed. However, the difference would only be tangible if one rides a lighter vehicle.

2). Due to the extra weight, FE might suffer too as you'd push the engine more to extract the performance desired. Heavy wrist action on a heavy bike would certainly be heavy on your pocket

3). Braking might suffer only if the weight of the machine is significantly high. In the GS's case, i don't see 5 kgs making an impact when the entire 150cc brigade (Save for the RTR, R15, FZ16 although these aren't part of the 'brigade' ) runs 240mm dia front discs.

Cheers !

Nope I am in complete diagreement with you here, even I have driven P150, kzm and cbz enough to pass on my judgement and GS doen NOT feel heavy while zipping through. Plus is all about what bike you were used to driving BERORE you stepped on to this one.........and ofcourse how well you adjust to the current one........The only time I felt its heaviness was while pushing it to n fro on stand still ( and that does not mean a thing). And saying "engineering a bike involves proper distribution of weight" is like challanging suzuki for an engineering fault....lol....cant be as biased an openion than this one.....as if suzuki is a "just launched" couple of years newbie company.........just because their bike have not captured the market as may be HH or Bajaj, you think its just another run of the mill company prone to engineering flaws.........think before you post a statement......

sam9s, how long have you been riding this bike? and how r the brakes working? i guess rusting may be due to the improper storage of bike before selling it...

heyy guys.. as i was tellin tht i will go to a local mechanic for my "ROUGH RIDE" problem, i met one.. acc to him its rough for a new bike.. he checked the valves/tappet, which could be causing the problem but he found it perfect.. he dint open the engine fully as it would have lost the warranty.. he asked me to wait for 2nd service..
i went for a long drive today(around 150 kms).. looks like this bike is made for long drives only.. its very smooth at high speeds and rough below 60(in my case only, no1 else has this problem).. touched 120 today, but it started wobbling heavily which scared me, so brought down the speed.
talkin abt brakes, i am not at all impressed my the brakes.. rear one is almost insignificant, and the front one is sluggish too.. i mean it works but a little later than usual disc brakes..
wen i came back in the city, my bike skidded at gravel.. thnk god, i was ridin at 20 only, so dint get hurt badly.. my right leg has swollen from here n there but i think its fine.. nothing wrong from bike side, it was my riding fault.

i think suzuki should have put a little wider tyre...

next time when you go for the servicing,pls raise the breaking issue...

Vibrations at 3000 to 4000rpm

in GS when u drive it in this rpm range u feel a mild vibrations (very small magnitude). this is not engine flaw... if it is engine flaw then the bike should vibrate even at stand still (stationary) at 3-4k rpm range... but i checked it doesnt THE ACTUAL REASON FOR THIS IS piston crank mechanism cant be completely balanced (fact) so all engines will produce vibrations, the point is to minimizing(using balancer shafts) it and damping(rubber mounts) it... there is some thing called resonance( if the exciting frequency matches with natural frequency of the system then the system will vibrate in high amplitude) here GS is system and its engine is the source of vibration... Shock absorbers, Tyre's stiffness contributes a SPRING and entire weight of vehicle is MASS this will contribute a spring-mass system... well it is known that these two parameters determine the natural frequency... i think GS's natural frequency lies in this range so it produces resonance... there is nothing to worry about this, GS has cute engine As sam said they are minimizing as the time... BIKES WILL SHOW ITS BEST PERFORMANCE AFTER completing 10000kms or more... So enjoy the ride

OFFTOPIC:
brother,,,,, i think you should think before you point out towards someone
now why ru ranting about its a SUZUKI ...... even YAMAHA and SUZUKI have made models which have failed in the market !!! ....... they had some flaws which are corrected in the later editions...... the sentence again n again u are telling that " it is a suzuki " ........ is because suzuki has made bikes like THE HAYABUSA N THE GSX and ............ but telling that they cannot be behind in terms of engg is stupidity at its height .....
the previous bike i rode before and adapting and all i understand it
u keep on telling this n i always told u that i rode many bikes ,,,,,,, n i dont think pulsar is light ...... or any other for that matter ..... yes i own the 135 but that does not mean i dont ride others
i was just posting information so that people might keep these points in mind while taking the test ride and see for their self whether it is correct or not or they are able to tackle the weight or not ........... no way i am against the bike u own or changing people ' s mind to not to take this GS 150R ............... and i also made the same point that at stand still n at LOW speeds at corners the weight might be a problem ........... otherwise in motion its ok ............... please DO READ PROPERLY what i say then shout at me

i love this bike .....yes i LOVE THE GS 150R so i am in this thread .......... otherwise it does nt concern me at all .............. i am here since u were the only owner here n i was one of the very first to take test ride
and i am just giving my OPINION.............. i think i have the right to do so

see above how mr.ssivakumar has tried to explain something instead of shouting at me ..... come on brother i am only a human n have no shame in agreeing that i am wrong and neither telling that i also dont have sufficient knowledge to talk about ENGINEERING of a bike may be ........
so you come out with a mistake in my statements with explanations and i will readily BOW my head and accept that i was wrong ............

i can tell out stuff but seriously i just dont want to speak anything more
just that dont want people to regrett afterwards
it very difficult for a normal person ,,,, hope u understand!!!!
so actually i was just telling them point which they should keep in mind while taking a test ride ......... if fine then go ahead with it

infact when shadowfax was confused it was me who told him that every bike has some flaws ..... even the high priced ones.... nothing is prefect.... even the GS has ....... everyone shouts out its a good bike bt does not comment on the cons ........ i think I am not getting paid like magazines to false praise it ...... read in every statement of mine that i tell people to test ride n decide n not to fall out for my statement

if u have any problem with my statement come out with proper criticism rather than acting ironical ,,,,,,,,,,,, and actually it was ur review that made me test ride this bike ,,,,,,,,,,,, so THANK YOU for that

phew ,,,, sigh
peace and sorry if you felt offensive
enjoy the ride

wider tyre would result in lesser mileage.. n one of the attractions of GS is its 50+ mileage... i find the tyre width is as par with other 150 cc bikes..
n ya, i hav to talk abt the engine n braking issues to the SC guys again.. lets see.

@outwardly_maniac - whoa bro!! tht was a huge post

i wished the tyres to be wider coz the bike has more height and weight compared to other 150cc bikes....

abt breaking, pls be strict with them....abuse them if possible :P but pls take the issue seriously with them...

sorry bro ..... but my friend angered me somewhat
btw i love ur dp..... its cool

Now where does it appear, that I am shouting, you posted your openion and I gave mine. I seriously think you over reacted. Again I would say failing in the market does not mean the product has engg flaws. All I conveyed from what I said was that your statement "engineering a bike involves proper distribution of weight" was to heavy consider its a suzuki we are talking about (you think they wont know that) ......again that does not mean suzuki is some God lord of engg technology but as an automobile company I think it has proved enough in all segments for us to actually question their engg..........

There is nothign personal against you bro....which by your post I presume you took........so chill out n peace here as well :-)

very well explained and good to see that some one realised that its not all vibs but hint of resonance that the bike has. I kept saying this but most of the people mistook it and labeled their fear as skeptical about going for this bike as there are vibrations.........I think your post would clear most of the doubt.

see the problem above !!!
get well soon brother

one thing..... designing a bike isnt a piece of cake ....... it takes tremendous amount of effort n genius to do so........ so when executing a project ..... however hard u try ... some flaws creep in .......... i would be stupid to doubt suzuki ' s engg definitely ............ but while running their concept.... they may have founded out that it was heavy ..... n now if they found out ..... what would they do???? design it again for reducing its weight .......... also the resonance effect and all that mr ssivakumar is talking about is also the effect of the bikes geometry n the things used ........... even that is not considered as a good piece of engineering

as i said in an earlier post that suzuki seemed in a hurry ......... it they had taken some more time ,,,,,,,, they could have taken over the rest of the market very easily when it came to 150 cc commutters
just imagine if these things were right .... it would have been simply unbeatable!!!
1. weight
2. brakes
3. that stupid flaw in 3k - 4k
and tell u what ,,,,, we would have had a wonder of a machine mate

but alas as i said .... making a bike is a headache ..... n takes a lot of effort!!! ..........

btw : how do u find its suspensions in pot holes n rough roads??????
i could not go in pot holes a lot so cannot comment to much ,,,, but i felt comfy ,,,,,,, what do u say/.?

thnx yaar.. its jus swellin till now.. mayb a hairline fracture, gotta see a doc..
i read mr. sivakumar's post and i had to re-read it twice to understand it.. its quite informative..
no other GS owner here is reporting the problem i am mentioning with my bike.. i am not worried about the 3-4k rpm vibes.. for me its rough at lower speed(<60).. for ex 3rd gear speed 30 it will start making a little sound and you will feel that the engine is taking a lot of efforts to pull it.. and SC guys rode it and told me its perfectly fine, that was the most irritating part.. at higher speeds it simply glides, no probs at all..
one more ques i have for all the bikers.. the max speed i had done till yesterday was 105 on a pulsar, but yest i rode at 120 on GS and it started wobbling heavily.. is it common for all the bikes/bikers?

he he... they have already spent more time developing the GS150R than anyone else did for any other bike made in India. Well over 2 years.

Dunno what Suzuki's take on these petty niggles

wobbling depends on various factors. First, 120 KMPH is a lot of speed and many cars wobble at such a speed. Dunno how good the GS150R is at such speeds but several factors do add in to the situation -

- tyre pressure - are you absolutely sure that your tyres are not over inflated? Tough one as most air filling points have inaccurate meters.
- how much of cross winds did you have? open highways generally have a lot of it.
- how smooth/rough the tarmac is... unless it is a smooth black top you don't get very good grip for your tyres at that speed with cross winds.
- Don't worry, in such conditions even the ZMA, P220 and R15 face this problem... the intensity would vary a little bit among each bike.
