Re: Suzuki Gixxer 155

On carb equipped bikes, it's generally the ignition system that performs this duty. After the set rpm, the ignition system cuts off the power to the spark plugs. No spark= no power= no raising of rpm. This eventually prevents the engine from revving beyond the set rpm.

[QUOTE=Avinash666;1124043]While I was cruising today I tried to find out the max RPM acheivable. So I put it in the 3rd gear and revved it. It rocketed to 10,000rpm. But after about 11,5000 it felt as if the bike was choking. It didn't rev up to 13,000RPM. I was at 90kmph and felt as if someone was pulling from behind.QUOTE] Hi, You are expecting the Gixxer to rev upto 13,000 RPM.!! Please note that Gixxer is a long stroke bike. with 62.9 mm stroke and 56 mm bore it has the longest stroke in this segment. There is a term called Mean piston speed, The average speed of piston going up and down during its motion.The piston travels 2 times the stroke of the engine in one rotation, multiply it with rotations per second you get mean piston speed in Meter per second. Normal engines(2 valve, cast piston, Built up crank, steel connecting rod) have a certain safe limit for mean piston speed even though they have a balancer shaft(Gixxer has one). For Indian bikes with above parts have max allowable mean piston speed some where around 20-21 Meter/second. Gixxer at 10000 RPM itself gets the Mean piston speed to 20.9 Meter/second. No way it will rev much more than that.That's what rev limiter is for. Suzuki engineers might have set it around 10000. The short stroke CBR 150R with just 47.2 mm stroke, 4 valve engine, has its rev limiter set at 11800 rpm, where its mean piston speed is just 18.5 metre/second. Ktm duke 200 with just 49 mm stroke and a single piece forged crankashaft and a forged/fractured two piece connecting rod with 4 valve engine has its rev limiter set at 10500(even though it is safe to till around 12000 RPM where its mean piston speed is 19.6Metre/second). No way Gixxer will rev much more than 10000 rpm. Then what you guys see in your digital tachometer is not correct indication of engine speeds at least near reline revs. And if it is really reviving that high (11500) it will strain the engine a lot.

Re: Suzuki Gixxer 155

This is the max RPM when the bike is on center stand and in 5th gear.
How are you guys achieving 11K+ RPMs

Re: Suzuki Gixxer 155

Mean piston speed - the term 'mean' itself implies average. So its the average piston speed. Which means the piston speed can go above it.

Re: Suzuki Gixxer 155

I received my grey gixxer yesterday. My initial response-waaav...
lot of positives.
-very responsive engine.
-superb handling ability
-all dc electricals, means no flickering of headlight
-comfortable seating
some pictures taken randomly in mobile camera are posted here.

Re: Suzuki Gixxer 155

Hi guys!! On the onset , let me first thank xBHP and all you guys for your detailed reviews and experiences of Gixxer. It not only helped me book it blindly in the first place but also helped nurture the biker spirit within me!

So coming to the bike now, booked it in October, got delivered in third week December. This beauty lives upto , if not more than ,its expectations.The blue color I feel just adds the cherry on the cake. First service over; this has turned into something different altogether, you never feel like getting off the bike itself! Have already done a Pune-Mumbai-Pune post service. Clocking 80-90kmph on the highway, I actually felt as if I was gliding; no vibrations at all. I am getting around 42 kmpl which is still ok in terms of my rough driving. Took some pictures during the said trip:-





This following one was taken just before entering the expressway from Lonavala. A very interesting thing happened here. Had got down to ask directions from a cop. While getting back on, he came running and stopped me abruptly; scared the wits out of me. Turns out he just wanted to check out the bike. Gave me a high-five while leaving!!









There have been so many instances where people just start staring at it while passing by. Gives a sense of pride just to own it! There's only been one problem though and it started only after coming back to Pune. Sometimes, the bike , on getting to neutral, gets stuck at 1-1.5k rpm. Doesnt come down below that, this usually happens when I do, say ,around 15-20 kms , not for short distances. Hoever, apart from that, its a true beauty to drive!

Re: Suzuki Gixxer 155

Mean piston is only a indicator, Nothing happens to piston because of this 20 odd Metre/second speed.It is the acceleration/deceleration of the piston at Top/bottom dead centre in magnitude of several thousand G's that loads the piston.Suppose a 100 gram piston is acted by 3000G Acceleration(gravity), the load on the puny 100gram piston is around 300KG.Mean piston speed is a good indicator to know at which level the piston is acting.Any way nothing to worry, all bikes come with Revlimiter set by the manufacturers.The bike doesnt rev beyond the rev limiter.Thats what Rev limiter is for. To limit the revs of the bike.No way any engine revs above the rev lmiter unless there is some problem.If there was no rev limiter the engine in neutral will rev to moon under full throttle and destroy Themselves.

Re: Suzuki Gixxer 155

I got the delivery of Blue Gixxer on Sunday i.e 4th Jan from Saptagiri Suzuki at Dr Rajkumar Road , Bangalore wow is just the feeling , till now have done about 300Kms on the beauty will post some pics soon enough , but mark my words it is just a brutal beast when it comes to acceleration.Till now the rpm limitor was set to 5000rpms to take care of 1st service , today got the mechanic to set it at lower i.e 4500rpms with flashing lights at the console for alarm.
But strange enough the ground clearance at 160mm does not do good in some of Bangalore's unscientific speed breakers got touched twice at the one's which are very steep but other cases where there is plenty of entry and exit there were no issues so took it to the showroom he just bent the bike and showed me that portion grazed was of center stand where I could find slight damage I was afraid tht the silencer portion was getting damaged apart from this I did not face any issues checked the mileage once with reserve to reserve method it returned at 45km/l and this was with pillion me and my wife and both of us are on the wrong side of 90kgs.
Handling wise or on the highway it installed great self confidence in cornering and rapid braking , really proud to own it , Suzuki has made a great machine after a long time Fiero was one good one back in it's days which I also owned
Meanwhile I have kept the tyre pressures at 30psi at the front and 36psi at the back with nitrogen

Re: Suzuki Gixxer 155

Hi guys,
I'm soon going to buy my first bike, (budget 80-90k) and I really like the Suzuki Gixxer. Any comments about its reliability etc? In the 150cc segment, the Gixxer is definitely my favourite. Fun to ride factor, quality and reliability are of prime importance to me. Please help!

Re: Suzuki Gixxer 155

For your problem of lower ground clearance, ask service centre mechanics to set the monoshocks to keep it in 3th or 4th step, i think it will solve the problem of engine hitting ground. My service centre personnel told me this

Re: Suzuki Gixxer 155

By increasing or decreasing the steps of monoshock will become soft or hard!
Loosening it makes it soft and tightening will make it hard!

Re: Suzuki Gixxer 155

In mangalore also the design and size of the humps are villain to bikes, so as per SC personnel, in the initial days of gixxer delivery many reported this ground clearance problem, so as per directions from company they adjusted the default setting of monoshock and now problem is not there.

Re: Suzuki Gixxer 155

Hi guys! I'm posting after a long time :-P
Got the bike and now it's due for first service.. The bike as such is not giving any problems except two.
First, the ground clearance.. With a pillion, it is inevitable to avoid the scrape on some humps, which is heart grieving
Second, sometimes when I Rev match to downshift, there is a knock kinda thing.. As though there is a reduction in fuel supply.. When I Rev again, it's back to normal... This happens rarely put it scares me when it does... :what:Is it a major problem??
And I'm giving my bike for first service tomorrow.. Any advice or suggestions??

Prospective Gixxer owner here! I just heard of some worrying reports of rusting problems for this bike. Any comments? Has anybody faced rusting issues esp. on the front forks, various nuts and the brake disc?
