well you're right in a general sense, but it depends on what you
want out of a bike? what makes a 2B 4-stroker suck?
ever heard of scavenging? that is a problem that all 2-stroke
engines face, no matter how intelligent or creative the engineer
who designed the engine is, he cannot get rid of this effect. a
2-stroke engine can never efficiently expel all its exhaust, the
details of which i won't go into, some fuel always gets ported out
with the exhaust before the next combustion. hence poor fuel
efficiency. 4-strokers don't have this problem. plus the cost of
2T? if low maintenance and high fuel efficiency is high on a
bloke's list, 4-strokers, 2B or not, definitely do not suck in this
aspect. and believe me, 2B 4-strokers offer more efficiency than
class 2A or class 2 4-stroke bikes, per litre of petrol. ask around
if you don't believe it.
as ah^huat has mentioned, the power for a 2-stroker comes faster,
since there's 1 power stroke for every 2 strokes (full engine
cycle); while there's 1 power stroke for every 4 strokes (full
engine cycle) for a 4-stroke bike. this makes the engine very
peaky, and have a narrower power-band. suitable for racing, but for
normal road use? you decide. the power delivery for a 4-stroker, by
contrast, is smoother, and with the larger 4-inline, or V4 engines,
you'll get a wider power-band, with a larger range of rpm at which
you have torque to play with. not quite the wild horse now, but a
more comfortable ride. which do you prefer?
2B V2 bikes include the honda varadero 125 and shadow 125, yamaha
virago 125 and dragstar 125.
it's all up to the individual. you wanna get started on a fast
bike, have some fun while you're at it, but bear higher maintenance
costs, get a 2-stroke. if you just want fuel efficiency and ease of
maintenance, get a 4-stroke. i suppose everyone's heard of the
process of burning carbon out of a 2-stroker's exhaust pipe?
ok i'm just generalizing here, but i think i've not made any wild
sweeping statements like 2-strokers suck ass. i could be wrong, in
which case, i'll stand corrected. hope i've not offended anyone
here. both types have their virtues, just up to the rider to choose
which they want.
