i have posted this in CARS…..do ure search first…this has been discussed…

KamHoe SG

I thought Bike also have the same things?

Rockhound SG

then u wait for the motorcyclist to reply lor.....this has already been discussed a few times in the CAR forum....if u search got 2 or 3 topics on SOHC and DOHC

ifv80 SG

DOHC double overhead cam
SOHC single overhard cam

its juz the number of cams above the pistons

Thanks.
Got the info.

Just have to do my "homework" before getting a bike of my own.

Rockhound SG

makes no diff for bikes.....

Class 2b.....2 strokes and some 4 strokes...

Class 2a and above...
v twins...inline 4...desmo enginess..testretta engines....dohc and sohc not so common except bigger bikes...but theyre unimportant imo....not like cars whereby need to noe...

v twins are like harleys...aprilia rsv...Hondar VTR.....their sound is a droning sound if u wanna noe...high in torque....

inline 4 is popular....R1, Fireblade, Gixxers, Ninjas...screaming sound in my opinion....faster acceleration than v twins...

desmo and testretta engines are restricted to ducatis...their own tech one...very high torque like v twins too..well actually they are v twins too..

wat else u wanna noe?

KamHoe SG

Wow. and I only qualify for 2 stroke and 4 stroke.

Smile hope to make my way up to the big ones soon.

You have a bike of your own?

Rockhound SG

actually 2 strokes are basically the 2B bikes arh....there are 4 stroke 2 b bikes too....2 stroke engines have higher power(theres a jolt in them compared to 4 strokers)....4 strokers have good low end torque...plus they combust fuel better
oh yuh...2 stroke u need to use 2t oil...if not piston jam for sure...4stroke no need...How u wanna differentiate 2 strokers to 4 strokers.....2 strokers the sound is like high pitch non stop farting.....4 strokers is more pleasurable...(well to my ears that is..)

when u go on to 2A-2...almost everything would be 4 strokes....and theres alot of kinds of 4 strokers around from v twins to inline 4s....i personally like v twins cos theyre of controllable behaviour compared to inline 4s which is all abt top end power...

nope...have a car license....but very interested in bikes....i'd like to own a ducati one day...provided i wanna take a bike license......
