What are your thaughts on the 4stroke racing dirtbikes and 2stroke

[MX125dude]

What do you guys think of a 4stroke racing with 2strokes and how the 2strokes and starting to go away. My opion is it sucks. I love 2 strokes i have one, a 2003 CR125, there so fast and powerful but yet the tree huggers want to get ride of them. They think they polute too much. But there arent enough 2stroke dirtbikes, quads, ect. to polute that much. Its all in factories and other things. I just wish yamaha never made the yzf400 :mad: . But what do you guys think. 4stroke racing dirtbike good or bad.

Well obviously you havent riden one of the new 450's or 250f's. Ride one then make a decision. The 4 strokes have a better power curve and they stay on the power much better than the pingers. The 4 stroke techonology is a help to our sport and is advancing the bikes every year.

Well i did ride a 2004 CRF250 and it felt kinda slugish to me. the 2strokes just seem to have a better acceleration to me. But its not that i dont like 4strokes cause the enduros are great but the fact that the 4stroke racers and going to make the 2strokes faid away isnt right. its what started motocross and shouldnt faid away. even if they do pollute more they should find someway to lower the pollution and put more effort into making them better. I just think its wrong. the only reason theyre becoming so popular is cause of polution but theyre arent enough 2stroke anything to make that big of a difference.

if it was slugish it wasnt running right. there are lots of two strokes besides motorcycles and atv's theres also trimmers chain saws and stuff like that. there are enough to pollute. dont get me wrong though econazis are still wrong. fourstrokes are cleaner running and in alot of cases make more power. i perfer four strokes but i dont think two strokes are bad. the four stroke revolution happened on the street it was only a matter of time before it happened in the dirt.

[MX125dude]

yeah i know theres other 2 stroked other than dirtbikes but its not like they are the only thing killing the ozone, if its even true. its all in other things to like airsole cans and power plants and other things.

WOW with that comment I am amazed by your lack of intelligence, they are becoming more popular because they are a all around better bike. I dont think any rider has chosen the thumpers over the pingers because of poluton. Riders dont care about polution its the tree hugers, now i'm happy it happened tho.

[TrikeKid]

i didnt choose a fourstroke bike because of pollution i chose it because it was what i needed and wanted.

[coyote killer]

I like to see all the development being done to the 4 strokes but I think they should reduce the maximum size allowable in the 250 class to 400 cc and reduce the 125 class to 200 cc because its clear the big 4 strokes have to big of an advantage....A holeshot on a 2 stroke is history.....

[MX125dude]

umm im not lacking intelligence, iv read all about the four stroke racers. it not that i hate four strokes i just hate the ones that race in the 2 stroke classes. there only more powerful cause they have to cheat by upping the ccs of the engine. its making the 2strokes look weak when their really more powerful then fours and thats why they up the cc on fours to make the power kinda equal but its still not fair to the 2strokes. they started motocross and because of the pollution most of the companys focus on the 4s to make more powerful not the 2s.

[TrikeKid]

if you look at hp numbers they are equal. they have to focus on 4's because they 2 strokes will be done away with in the next few years. fourstokes are the new thing. i have no problem with two strokes and will be racing one soon i prefer fourstrokes and probly always will. fourstrokes are here today and you just have to live with it. there are no "two stroke classes" there are bike classes. i think alot of two stroke riders that gripe about fourstrokes are mad because they are getting their butts handed to them. its still more rider than anything. a two stroke can beat a fourstroke on any given day and vice-versa.

I disagree...Whens the last time a 2 stroke got the holeshot in the pro's???Look at Stewart,,,,he never gets a good start because hes on a 125....

I get them all the time, wait you wanted pros. So now your comparing pro bikes to regular bikes. Rember they are COMPLETLY diffrent,nothing is left the same on them, so you cant compare a stock bike to a pro factory backed bike. Go to your local races and watch. At the track i race at i always get the holeshot (too bad i cant ride the rest of the track) then about 2 125's right behind me. I can smoke any 250f, (but i have a yz175, he he i got a big bore 125) but even with a stock 125 they keep up, if not beat a stock 250f. To make the new thumpers run decently you have to get a pipe and jet it. Straight from the factory they run like crap and any deascent 125 will smoke em.

The pro's is the only place where extra HP makes any difference....In the intermediate and lower classes the only thing that counts is the skill of the rider.....I ride a YZ490 but I cant use all that HP anywhere other than a dragstrip.....Dont tell anyone,,,,but I know 80cc riders that can smoke me and my 490...LOL!!

Heres the 2004 dyno tests.....the 4 strokes have a 5 HP advantage or more throughout the powerband....Thats roughly 25% more hp....A BIG difference....Unless they reduce the max allowable 4 stroke displacement then you are witnessing the death of the 2 stroke....

see thats what i meen they are focusing more of the power and developement in the fourstrokes, and it is because of the polution!

[TrikeKid]

no sh!t sherlock. they're focusing on them because they are banning the production of two strokes in a couple years

[MX125dude]

well is it because of the pollution? and if they are banning them does that just meen they have to quit the production of them or no one can even ride a 2stroke?

[speed20]

Just look at it this way.....it takes twice as much power for a 4 stroke to equal a 2 stroke, so the 4 stroke bikes are going to be heavier, harder to manuever, and 2 strokes may stop being produced, but they cant take them away from us. its like ford and chevy, whichever you grew up on or believed was better, you would get....Ive rode a crf250 and a yz426f, and they are nice bikes, but i love my 2 stroke 250 because its peppier, and is lighter than the 4 strokes, which makes it easier to manuever and jump. I dont think they will quit producing 2 strokes personally....it gives the big companies like Yamaha, Honda, Suzuki, Kawasaki and KTM more competition this way....what fun would it be to have all the same bikes in a class??? it wouldnt be, there would be no competition between the bikes, its all in the riders capabilities. Ricky Carmichael prefers the 4 stroke Honda, Chad Reed Prefers the 2 stroke Yamaha, Clark Stiles prefers the 4 stroke Honda, James Stewart Prefers the 2 stroke Kawasaki....its hard to get used to riding a 2 stroke when you were raised on a 4 stroke and vice versa. I think putting 4 strokes and 2 strokes together is a good idea....its pretty much putting old technology up against new technology.

[coyote killer]

Reed may prefer 2 strokes but he still has to ride the 4 stroke to compete....

[speed20]

I dont believe that he has to ride the 4 stroke to compete....he seems to win or atleast get second alot....before Carmichael came back, he won pretty much all the time....its not because Carmichael is on a 4 stroke, its all rider ability.

[TrikeKid]

well is it because of the pollution? and if they are banning them does that just meen they have to quit the production of them or no one can even ride a 2stroke?
yes its because of polution they are doing the same kind of ban they did on trikes they're just stopping production.

[coyote killer]

I ask again,,,,when is the last time you saw a 2 stroke get the hole shot???That pretty much tells the tale right there.,..
