2-stroke VS 4-stroke Bikes
-
What is the difference between these two bikes in comparison?
Any websites out there that hav information regarding these two comparisons?
Thanks alot cos I have to do a report regarding their difference..... . -
http://www.howstuffworks.com/two-stroke.htm
the above is for 2 stroke.
as for 4 stroke leh, see: http://www.howstuffworks.com/engine.htm
cars oso run on a 4 stroke engine
hope the info is useful. i realised a lot of things i dunno -
jia sai la Vspec...next time dun ask me gai siao u jobs.

4 stroke is so much smoother!!!.... anione selling xr4? me tinkin of changing bike.Originally posted by VspecR34:What is the difference between these two bikes in comparison?

is it possible that a 4 stroke bike having a bigger HP compared to a 2 stroke bike?? Lets say same c.c.

everything is posible!Originally posted by eric_jugonz:is it possible that a 4 stroke bike having a bigger HP compared to a 2 stroke bike?? Lets say same c.c.
but unlikely they will b any 4stroke with HP bigger than 2 stroke on road!
anyway 2 stroke will beat 4 stroke flat if same cc. even bigger cc!
example will b phantom 150 vs phatom 200cc -

1st lets see the example of phantomOriginally posted by eric_jugonz:is it possible that a 4 stroke bike having a bigger HP compared to a 2 stroke bike?? Lets say same c.c.
150cc 2 stroke vs 200cc 4 stroke.
150cc sure out performs the 200cc.
reason being 2 stroke more power.
pickup is good for 2 stroke but the wear and tear is very much higher. and need 2t oso
how often do u see a 4 stroker like a car changing piston or changing valve.
car change piston i never even hear b4 sia.
MotoGP got a chioce to see 4 stroke or 2 stroke machines mah
y do u think they choose 2 strokers ?
its your chioce lah.
to me 4 stroke more wu hua. no nid use 2t liao -
2 stroke burns once for every engine rev.... 4 stroke burns once for every 2 engine rev. The 1st rev is to compress the gas, second rev is to burn....so you would roughly get twice the hp for 2 stroke bike as compared to 4 stroke wif same cc.Originally posted by VspecR34:What is the difference between these two bikes in comparison?

This is in theory but practically, it all depends on the compression ratio, mechanical efficiency, friction, weight. In short, bike and engine design that determine the performace of individual bike. -
actually i know how the 2 engines works, and the differences but my friend say my phantom 200 pick up quite fast... and he riding KRR 150!! that's why i'm asking this loh...Originally posted by Aprilia Rider:1st lets see the example of phantom

Thks for ur replys guys....
But I really need lots of information for the report in Sch.
One thing for sure is the bad emission frm 2 stroke...., seems like there's little info I can find on the web...
Why issint the upcoming MotoGP, their changing 4 stroke instead? -
becoz 2 stroke = fast.Originally posted by VspecR34:Why issint the upcoming MotoGP, their changing 4 stroke instead?

U compare the bike's sprockets firstOriginally posted by eric_jugonz:actually i know how the 2 engines works, and the differences but my friend say my phantom 200 pick up quite fast... and he riding KRR 150!! that's why i'm asking this loh... -
erm... dun understand, if can please explain...Originally posted by operator:U compare the bike's sprockets first -

2 stroke engines use this process called "scavenging" to recharge the cylinder with a new air/fuel mix everytime. it's due to the engine design of not having valves like a 4-stroke engine (but the piston and crankshaft in a 2 stroke act as valves). as such, it's highly possible that unburnt air/fuel passes out the exhaust pipe with every engine revolution. this is the main emission issue regarding 2-strokers. hope this helps.

the larger the rear sprocket, the better the pickup. physics, but i can't remember which topic liao... hahaha... go tell a bikeshop mechanic that you want to fit "bicycle chain", and he'll know that you want a larger rear sprocket. of course, your top-end would be hurt if you do this.Originally posted by eric_jugonz:erm... dun understand, if can please explain...

oohh... thanx...Originally posted by l3stat:the larger the rear sprocket, the better the pickup. physics, but i can't remember which topic liao... hahaha... go tell a bikeshop mechanic that you want to fit "bicycle chain", and he'll know that you want a larger rear sprocket. of course, your top-end would be hurt if you do this.
but phantom 200 top-end very poor liao... dun think will sacrifice this... -
why GP phasing out 2 stroke is due to environmental issues, soon the whole world will follow suit and 2 stroke bikes will be a part of history. yes it is true... no duobt abt it.
the science and engineering behind the engine mechanics is too far beyond our knowledge capabilities. there must never be a general statement abt de differences and advantages of 4 stroke vs 2 strokes, simply bcos every single engine make is different, down to every small millimeter affects the compression ratios and blah blah blah....
the differences can be stated, but their pros and cons cannot be generalised.
Vspecr34 if u need more info on 2stroke and 4stroke lemme know. i bring u to my library help u find. -
eh... it's not really about top-end lar.. cos after all, how fast can you go? and for how long? don't risk that license... instead.. pickup can save your life from errant and blur drivers.. get you out of life-threatening situations... but of course.. get used to the new sprocket first...Originally posted by eric_jugonz:oohh... thanx...
but phantom 200 top-end very poor liao... dun think will sacrifice this...

Ur top end is weak...bcoz ur pick-up is gd. If u compare p200 with nsr. The back sprocket(Gear) would have been bigger and the front sprocket(pinion) would have been smaller.Originally posted by eric_jugonz:oohh... thanx...
but phantom 200 top-end very poor liao... dun think will sacrifice this...
Basic mechanical stuff -
Just ride 4 stroke bike lah... save money..
low maintenance.... Moreover, how fast u can
go in S'pore...!!!! haha...

2-stroke wears out faster than 4-stroke.
2-stroke gives it's best power at high rev.
4 stroke has great pulling power at very low revs, but they often hav respectable spread of power over a wide r.p.m range.
My opinion, 2 stroke better to "Lut" lah, hahaha..., think you guys will agree with me.
Hey, I3stat, I can't acess to the website that you gave me: //sbo.co.za/tech.
Pls reply...., thkz! -
er.. i think the webhost got problem, cos other pages from that site can't be viewed as well, tried to access the cagiva planet and mito review for another post, but didn't work. try another time? it used to work... =/Originally posted by VspecR34:2-stroke wears out faster than 4-stroke.

sorry but i wan to ask, does 2 stroke bikes got valves anot?
i saw in the website that 2 stroke engines doesnt have valves unlike 4 stroke engines have...
but i always hear ppl say go wash valve on their SP, or other bikes leh..
care to enlighten on dis?
thanks
