  DOHC double overhead cam
  SOHC single overhard cam
  
  its juz the number of cams above the pistons

  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?

  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......
