We were bar to bar all the way. NO difference. Except mine had a head start being a four stroke & quicker off the line plus 50cc less. Work that out. Also when we go riding we would swap bikes. Within 5 minutes I wanted the CRF back. Way more fun. Instant power & allways having to sit on the petrol cap because all it wants to do is mono. I think stock for stock the 4 strokes have the advantage but ive got a 2001 CR250R that I bought from a guy who runs the bike dyno in town and he'd spent a fair bit of time getting all the jetting right, has heaps of low down power for a 2 stroke. I have not come across a 4 stroke anywhere that beats me in a straight line drag race. Always pulls away from any 450 I have raced both standing start and roll on and thats 200cc less not 50 more... There is one guy I know with a full race setup YZ450 that goes bar to bar with mine, they're so close it really comes down to the rider and how good of a launch you get. We ran them over and over and you couldn't get more even. I'd say theres a fair chance your mates CR500 isnt running to full potential especially if you're swapping bikes and asking for ya 450 back within minutes cause the CR500 doesnt have you sittin on the petrol tank trying to hold it down... 2 stroke 500's are scary as **** when setup properly but if the jetting is not right its not going to perform. I wouldnt judge all 500 2 strokes on that one bike. The new Service Honda CR500's are mint! Dont get me wrong tho im not a 4 stroke hater by any means haha the new 4 strokes are awesome, really usable power! I think the dude saying its like a turbo 6 and an 8 is a spot on comparison. If you wanna compare em head to head it really comes down to the bike in question, how well its setup/tuned and who's riding it not whether its a 4 stroke or a 2 stroke cause they both definitely have there advantages. I wouldnt mind the new service honda 2010 Stealth 500AFX, sick bike but there pretty expensive by the time you get it to oz dont think they make them locally! http://www.servicehonda.com/custom-bike-gallery Heres mine, it's been awesome bang for buck only cost around 3 grand. been meaning to get a new seat, dude I bought it off used it for fmx.

Them service hondas are sooooo sexy. 10 grand+ though. Not sure if that even includes shipping. It's a death trap.

Before anyone says two strokes are better has anyone ridden a 4 banger. The reason I didn't like the CR500 was because it felt like sh!t. The hole seat & weight thing was wrong and your saying a 250cc two stroke would beat a 450 race bike. M8 you must have stones in your head. lol. I haven't had any 2 stroke beat me yet.

Ive ridden plenty of 4 strokes, there great and stock vs stock i think they do have an edge especially in an average riders hands. The CR500 you rode is from the old breed its actually more like 15 years old in terms of frame/suspension etc. Have a read of this, its pretty much a shootout between your bike and your mates bike of which they all claim the 500 is faster and more explosive but with **** handling using 92 model frame/suspension: 08 CRF450 vs 01 CR500 shootout. (http://twostrokemotocross.com/2008/10/mxa-shootout-crf450-versus-cr500/) The new Service Honda 500AF's however use the latest CRF250 frame/suspension etc but with a 500 2 stroke engine, they are an awesome machine. Take a look at the AMA Championship list (http://www.motorsportsetc.com/champs/ama_sx1.htm) it was dominated by 250 2 strokes from the beginning all the way up till 2006 and that is when all the top guys stopped using 2 strokes and the teams switched to the new breed of 4 strokes because they're easier to ride reliably fast lap times with the power being much smoother and more predictable. James Stewart actually won a bunch of motos around 2006 on a KX250 against the other top guys who had switched to 450's before he made the jump as well. The 2 stroke 250's might take more skill to put down the same lap time but don't count them out in terms of sheer acceleration when setup properly. Wikipedia lists the 2001 CR250R (http://en.wikipedia.org/wiki/Honda_CR250R) as being regarded as the best 2 stroke MX bike of all time. I dont see how its so hard to believe its every bit as fast and faster than all the 450's I ride with considering its highly modified and has been dyno'd with correct AF's for where I live. If you think your 450 can flog any 2 stroke 500 you're the one with rocks in ya head mate

Q:AND THE POWERBAND WINNER IS� A:Need you ask? The CRF450 wins the overall powerband category.

Yeah, because it is smoother and easier to ride for noobs. Q:WHICH ONE MAKES THE MOST POWER? A:Stock for stock there is no comparison—the CR500 two-stroke pumps out approximately 55 horsepower, to the 50 horsepower of the CRF450. If you doubt those numbers, you will be convinced by turning the throttle wide open on both bikes. The CR500 explodes, while the CRF450 churns its way forward. In a test of sheer power, the CR500 wins. And that is virtually a 1992 model CR500 they're comparing with the 2008 CRF450, not the 500AF they're producing now which uses the same frame/suspension as the latest 450's but with even more power again and a more usable powerband. In terms of raw power its no contest mate, you're dreaming if you think otherwise.

Next thing your going to say that the CR500 rev's harder or higher lol. Also you'll be saying a two stroke is better for the bush. It's all about putting the power to use. Who won the blue light rally where I live. A four stroke. With over a 1000 riders of two & four strokes. A four stroke won. Well I be dammed.

There's always going to be pro's and con's on both types of engine and there is always going to be a never-ending debate on which one is better. At the end of the day it comes down to your own personal preference and type of application your looking to use the bike for and whatever your comfortable riding. On another note let's get some pictures up Some original photos have not been recovered yet.

Mate I've continually said four strokes have a much smoother more usable powerband which makes them easier to ride and therefore faster in a race track situation. There is no debate the four stroke is faster around a track unless you get the right guy/right track for a 500. You know KTM have released a 350 four stroke, and that it beat the 450's in the first race they put it in? Power doesn't equal fast lap times. It's more to do with the rider, there's no reason the same guy who won your rally couldn't have won the same race on a KTM300 or CR500AF. In fact most of the euro trail/offroad races are won by KTM300 2 strokes and they're considered some of the best trail bikes around. Have you ever seen Red Bull Romaniacs? Im not trying to wipe 0.5 seconds off my laptime and prefer the raw power delivery and scream of a 2 stroke plus they're vastly cheaper to run. You're ignorant as **** if you think 2 strokes can't compete and are a thing of the past.

Just face it, 2 strokes are being slowly out phased. They will be the thing of the past. Love the sound of a rev limiter on my CRF450R. BTW I don't think AMA will bring back 2 strokes to soon anyway. I sick of argument. This could go on for days. Let's just leave it at, I like my 4 stroke & you like your 2 smoke. Wasn't this thread about 4 stroke motocross bikes??

2 strokes are going to be around for a while yet mate, the new KTM 300's are an awesome bike and are selling well all over the world. If you actually took the time to throw a leg over a Service Honda 500AF you'd be singing a different tune I think. Just the same as there will always be turbo 6's and people who love them even though they don't race V8 supercars anymore. Is a V8 superior to a Turbo 6 because it makes more low down power and can deliver it smoother? Maybe to some people, but to others the feeling of a turbo hitting boost is what they enjoy. All im saying is don't be close minded and think four strokes are the only thing worth riding... a screaming 2 stroke 500AF is something to be respected regardless of preference! The thread might be about 4 strokes but that doesn't mean you can bash 2 strokes freely and not expect anyone to defend them Some original photos have not been recovered yet.
