Re: Suzuki GS150R

Hi Durai,

After your post I was also curious to test speed w.r.t RPM of my ride. I tried finding good time on the way to my office however it’s intermittent crowd on street within city & it’s risky too.
I decided to have a small drive city outskirt and planned for Ranjangaon Ganapati -55km away from Pune & test the GS-adrenaline.

It’s been now 4100km ODO and second servicing done recently. Before this I stretched speed up to 85km/hr but never thought of crossing 100km/HR limit coz still feel like engine needs refinement after break-in.

On highway I able to stretch up to 107km/hr. for consistent 15-20 min, I was with pillion (my wife) and overall weight approximately could be 130kg. Bike behavior changed suddenly after 85-90kn/hr. Overall reading was like this,
@6000RPM-80km/HR
@7500RPM - 95km/HR
@8000RPM- 107KM/HR

I wanted to stretch further up to 120 but my wife was so scared and forced me to slow down.

I found a guy with Karizma was chasing me desperately but he unable to catch me until I reached my destination .

Finally I came to conclusion that real world figures are more important than technical figures provided by company. Moreover rider’s faith & engine capability provided it’s well tuned.

Today I am assured, only 150cc bike that can beat 180/200/225cc Indian bikes is Suzuki GS. Controversy, only 150cc bike that is slower than 100cc bike & in 0-60km/HR is GS.

@ Durai, above figure aren’t not manipulated & I have no intention to misguide people on this forum.
@Others experts, please suggest if these figures are ok or are there still areas of improvement

Re: Suzuki GS150R

Yar Bro Happy to hear you achieved good speed figures But angry on you since tried it without providing any proper safety gear for pillion(i e your wife),you scared bhabi .

----consecutive posts auto-merged-----

Once again complain in Suzuki website that you still have problem with fork.And before that ask a good friend or mechanic the ride your bike . You can ask for replacement provided the bike hasn't met with any accidents that can damage the fork(warranty period 2 years or 30k kms whichever comes first).

Re: Suzuki GS150R

Today i bought a fuel test can and calculated FE. I filled in 100ml of petrol and did the test for 3 times. The average i got was 50KMPL. But when I do the reserve to reserve method i was getting 36 to 42. What could be the problem? Could there be any issue with fuel tank or knob? Please advice what can be done to this? Thanks

PS: I changed the fuel knob in the last service.

Re: Suzuki GS150R

When you used a 100ml test bottle , your run is short and the bottle well sealed . So you have eliminated evaporation loss .

In our climate , evaporation loss is considerable from the bike's fuel tank because of a) high ambient temperatures b) fuel tank is not hermetically sealed by design c) longer duration petrol remains in the tank owing to larger volume ( compared to the test bottle ) .
Your findings are normal , there is no problem in your bike .

Re: Suzuki GS150R

I understand this phenomenon. Also a 10% loss is fine, but this seems to be very high % loss. How do we justify this?
PS: The test bottle is not air sealed and has a very small hole on the top.

Re: Suzuki GS150R

Try testing with 500ml of petrol.You should get a more justified result.My bike a showed an impressive result of 6.5 km for 100ml thats 65kmpl but it actually returned only 40 kmpl which i found later due to choke jamming and improper tuning...

Re: Suzuki GS150R

107KMPH seems pretty much a wall for two-up riding. I reached the same speed with my wife on GS. I strongly doubt whether you will be able to reach 120 two up, unless supported by slope, tailwinds and luck.

Brother, forget Karizma or high powered vehicles. The ZMA rider was inefficient it seems. I have GS150R and have ridden ZMA as well. ZMA is pretty far ahead of GS, so no use of trying to convince ourselves how our 150cc engine beats 223ccs. Not possible as long as both are relaxed engines (forgot technical names) unlike RTR or R15 . I will suggest you enjoy the smoothness and comfort of bike rather than comparing with higher cc bikes. It will only bring unhappiness!

Re: Suzuki GS150R


Bang onnnn!! Ride with pride!

The max one can rev the engine at 6th gear is 127kmph and that is only when you put it on the stand and march with the dare. The bike is very capable as a commuter and can do the city traffic zips. Great on highways. The thing that I'm not satisfied with is servicing. It's not really up to the mark unless you beat the drum and make them work for the amount paid! Done 11500kms, 19 months old bike.

Re: Suzuki GS150R


@amimeher , I am absolutely agree with you bro. Not comparing any bikesover here but just want to focus on how two different machines can behave whenit comes to the top end speed. <100kmph.As I said overall riders faith andbikes tuning helps a lot in achieving certain speed figures. You won’t believeI had a TVS star City which was too comfortable reach to <90kmph and wascapable to smoke power Bajaj/hero bikes. Should I compare Star citywith Pulsar 150?? Surely not - coz 100ccis not high torque designed machine. So my top end momentum or accelerationcould last for a memento and gradually will lose. Same case I wanted tohighlighted when a Karizma was chasing me I felt like GS memento is uniformdelivering same power. On a highway Ican’t say a guy riding Karizma inefficient & that’s too with desperation tochase me?? Technology makes a difference this is I believe and not CC/Highpower, n that’s why many wise people prefer 150cc R15 (cost 1.35 L) thanKarizma 223cc (95k).


Though GS is 150cc there is no hesitation to reach>110kmph (& above 130 solo Ref: You tube). So Karizma being 223ccpractically we can expect 150kmph (right??) but in real life it sucks to reach120-130 kmph so marginally I can’t see so much difference. (Ref you tube forthe top end speed of Karizma)

All people on this forum might have experienced Karizma’sspeed and thrill but off course am not comparing R1 with Karizma or Hayabusawith GS to convince myself. With only cost of 80k I could understand the limit- what I am getting.


Give me practical examples/figures of how much a Bajaj &Hero bikes having relaxed engine at top end (in terms of smoothness &engine sound).

Any clarification will definitely clear the sky.

Re: Suzuki GS150R

He, animeher, is not at all an experienced rider. All his experience on a bike is nothing more than as a short distance city commuter and hence those words from him. Let us pardon him for his ignorance.
In my opinion, GS with 140 Nm torque and 95 km/h speed at 7000 rpm is superior to Karizma with mere 175 Nm torque and 108 kmh speed at that rpm. Torque of both bikes are at 6,000 rpm and is after primary and final gears.

GIXXER 155 (Full DC) specifications.
GEAR RATIOS
SPEED @ RPM.
First servicing is between 750-1000 kms. Periodic servicing in every 4000 kms instead of the GS's 2000. Engine oil and oil filter is to be replaced initially between 750-1000 kms and in every 4000 kms thereafter and the air cleaner in every 12,000 kms.
FE claimed by Suzuki is 64 KM/L. I think it is possible as there is a facility to limit the maximum reachable RPM from 4000 onwards, pre adjustable by the rider.
Riding position is slightly forward leaning than GS. The maximum speed I have reached on the test bike was about 100 kmh at about 7500 RPM. The gear ratios are favoring speed than torque but the hindrance here is the 140/60-17 tire with mere 1883 mm circumference where it is 100/90-18 with 2002 mm circumference on GS.
The larger disc brake provides sharp and precise - dangerously sharp and precise - stopping.
I didn't get a chance to check the brightness of the headlight but it is, as in any other lower cc bike, 35/35 watts.
What I dislike:
1. The smaller tyres which affect speed.
2. The toe shift gear lever which ruins the shoe of the rider. A heel-toe shifter was better.
3.Lack of sixth gear.

Re: Suzuki GS150R

If only!

RaviRaj123 : Have you ridden ZMA 225? I have for a small distance, and felt it to be superior to my GS. YMMV based on experience of rider/age and condition of machine. Physics says one thing, but experience can say another.

Re: Suzuki GS150R

Waiting for this specifications from past one week.(Compression ratio and gear ratios).
Where did you get these? ownership manual?
What about mileage figures?

Re: Suzuki GS150R

The specifications are from user's manual. Mileage claimed for GIXXER by Suzuki is 64 kml. For GS it is 62 kml but I have achieved 70 kml for test ride and, still, after 4 years 7 months and 39930 kms, getting an average of about 60 kml on it.
All gear ratios, I mean the overall gear ratios, are taller compared to GS. More than that, Gixxer's kerb weight is 135 Kgs i.e. 14 Kgs lighter than GS. This together with the advanced technology to reduce friction loss makes Gixxer more fuel efficient than GS;I hope.
Though the wheels are of smaller diameter, Gixxer gets almost the same speed of GS at the same RPM due to the rear ratios.
Due to more torque and less weight, pickup of Gixxer is excellent when compared to GS or any other 150 cc bike.
The brake disc is larger than GS's and it provides sure stop.
And there is a 'rev limiter' which limits the engine RPM from 4,000 to 9,000 in 500 RPM steps which can be adjusted by the rider.
SPEED OF GIXXER AND GS



I am planning for another test ride tomorrow to check the actual FE.
