Thread: 2's Vs. 4's

thats awesome how often u get to ride, but have u ever let him ride yur bike and u ride his 450. i believe u that u beat him, if u ride a 2 stroke right it is technically faster, but if u fall of of yur powerband yur screwed. ive ridden 2's before, but i just enjoy having power even way down low. its rider pref and skill that determines whos gonna go faster.

where do u guys ride?

good stuff, have u even been to st. joes? thats a pretty nice place with sand flats and trails and its only $3

man im not lookin forward to the next teardown of my rmz250. there are a lot of parts that need replacing on a 4 stroke if u want to do it right. next rebuild is definately gonna cost at least $1000. going for full set of kibblewhite valves, wiseco high compression piston, hinson basket plates and springs, and of course new tires. if i have the extra cash i might look into new cams, such as hot cams. anyone had much experience with those? noticeable diff from them? ya i guess all this work is worth having the power of a 4 stroke.

well, ill answer questions 1 and 3 first. so even though the engine has twice the displacement, and many more parts it only weighs around 7lbs more. my rmz250 is titled at 203 and yamaha claims 196 for their yz125. in my opinion dealing with 7lbs more is worth having real usable bottom end power. also 4 strokes do cost many many times more to rebuild. I MADE THE SACRIFICE to ride a 4. i know wat things cost and am currently dropping $1500 on my bike. i couldnt afford a 4 and started with a 2 but i worked my way up to a 4 and the difference in power is insane. also if a 2 stroke was a superior engine dont you think the pros would be racing on 2's instead. granted i know many pros still use them, but lets look at supercross. ampd mobile world tour, 4's. now theres got to be a reason........???? the engines are superior. its just that simple, if 2 strokes were better they would be using them but they dont! also wat does it matter if displacement is double? its actually kinda sad because bigger displacement == more friction on the walls because of more surface area and a heavier piston, BUT THE 4 STROKE REVS HIGHER THAN THE 2! plus not only is there more friction and weight in the piston, there is also so much more rotational mass such as a pair of cams, the force of the valve springs on the cams, the cam chain, and cam sprockets. yet somehow the 4 is still reving higher than a 2. so as far as #1 i dont know why the settled on twice the displacement but it works. #2 if u want to ride a 4 you're going to have to make the sacrifice in cost. i barely have money but riding is my life so i sacrificed other things for my bike. #3 would people stop saying that 4's are so much more in weight. wat is 7lbs. you wont even notice it, plus the enigine angle and the height of where the engine sets in the frame makes 4 strokes feel nice and light. ya i know fmx pros roll with 2 strokes because of that 7lbs not to mention that all the rotational parts throw them off in the air. #4 ya, i know, 4 strokes are better. those are my feelings and thanks for letting us know yours. happy to have you on this site.
