fz150i 140kmh=160kmh lc135=160kmh 125z
my fz can goo 160-170kmh..so,calculate urself..
at highway,they r food to me..
muahahaaha!

support 4stroke..
say no to preeengg preeeng..2t and 2stroke..
say no to sound pollution and air pollution..
ehheehe..
NO HARD FEELING!

Vat is the engine speed when it reaches 170km/h? R U still using standard final reduction ratio?

yes..go 4 a bike in 4 stroke if possible ..Go green!!

bro ur fz fast wo..=>
my friend d fz only cn reach 140 max..but the bike FC damn good..

woaa man! ur FZ damn fast! 
im never ride my FZ more then 100km/h....
coz im juz using it as my daily commute to work...n its alwayz jam, never able try speeding more than 110
but im prettyy sure can go up till ~130km/h...btw, im using bigger tyre, maybe the meter reading not really accurate... 

im already installed racing cam + UMA racing fuel injector controller....both of them gimme more pick up...ez to reach top speed...but im rarely switch on UMA...coz its fuel cosumption....

in the process of changing my standard block to racing block...

depend on which version of 125z, old meter is on heavy side, new meter is kinda cheat.

Max speed for my 125zr , 190km/h new meter, maybe 160-170 on fz150i meter.

My Krr 150 clocked 190km/h with all stock except smaller maxxis tyre of 100/80. Now using michelin pilot sporty 110/90. It managed to do 170km/h.
Nice bike to use especially when cruissing at the highway. Last time i use 125zr. Everytime on highway when lori lalu, i will go to the edge. Now i always maintain on 2nd-3rd lane. So far no any problem such as tayar pancit at highway or what. My cadangan if u are crusing at highway a lot consider buying a 150cc bike and above. Because 1st the tyre is thick and big.So less probability of tayar letup and the bike will not goyang easily..
@nd the aerodynamic of the bike 150cc n above is high.Less air resistance and relax while cruising. I can do 160km/h in just 1 hand oh the handle. Have you seen how those using moped motorcycle such as 125z, wave or LC, creating aerodynamic by forcing theirself to be close to the motor head while on highway. This is dangerous and can cause jantung berlubang, as moped motocycles no windshield.

So if you are cruising on the highway frequently, Consider getting a bike of 150cc n above. No more hassle of forcing yourself to create aerodynamic by leaning towards the motorhead..

u r u sure?ur bike 170km/h?any mod?
did u use any GPS?izzit long run to reach?
2 stroke engine oledi enhanced/advanced, not all produce air pollution.and even better.
but the fact, let me get it right, the sound of a two stroke may be louder when you are right next to it, as compared to a four stroke, that sound does not carry near as far. The booming four strokes can be heard for literally miles away.
my bike reach 210km/h at sepang but i still believe its around 190-195km/h.tested with my friend's CB400 vtec.with GPS also.
in case, i see ur bike at highway, then u r 'food' to me. 

no hard feeling bro..

u mention that ur  using 110/80 at the front,120/70 rear, quiet big for 150cc..so ur speedometer 'heavier' than other bike.but good for long distance.comfy.
no la.my bike cant run top speed too long like 4 stroke bike. later u can catch me back. lol.at highway la.at the track there's another story 
did u run it on track?Elite track?sepang?come lets hav some fun.not race each other, just feel the corner.just for fun bro.lol

PS.. - this is ryugan posted. accidentally using sniper69(my brother) acc. sorry

Gilera SP180 2 Stroke 140kmh = 180kmh LC135.
My Gilera SP can only get to 165kmh.
My friend Gilera SP can go to letter A which is around 200kmh.
For air pollution I agreed but not for sound pollution.
Sometimes 4 stroke bike more 'memekak' then 2 stroke bike. Huhuhuuhu...

^ ya2...agree with ur opinion bout the sound...
nowadays can put lots of aftermarket exhaust...juz pick wat u wan...

but im some more love 4 stroke rather thn 2 stroke...
love the pom pom sound rather than preng preng...my 2 cent, no offense...

my former 09 er6n = 210kmh.. haha
