Honda Dirt Bike Shootout

[Duke Nukem]

Here is a good shootout for 2-stroke fans out there. I just found it, don't know if everyones seen it by now.

interesting, I wonder what would be the result if the service honda cr500 was used instead of the 01? Unfortunity, as much as I love 2 strokes, 4 strokes are easier to ride. To race a 250r, you got to work the clutch, shift alot and brace the hit. For a 4 stroke, you can almost leave it 3rd gear the whole time, shifting the 4 and maybe 5th on the long straightaways.

cr500 ftw that bike is a beast and is the only thing that makes grown men cry its so scary fast lol the throttle is like a light switch you breathe too hard on it and your laying on the ground.

Not exactly like a light switch, but it can be explosive. I have a great deal of respect for mine. It came with a Pro-Circuit pipe and it was just TOO much to hold on to. I put the stocker back on it and it became somewhat more manageable.

man they must be fast :eek2: im not gonna lie, i think thats the first time ive heard of someone who wanted their bike to be slower

[D Bergstrom]

I miss my 2001 that I sold a while back. Whenever I rode it, it would always put a smile on my face, soon to be followed my a look of terror! I actually went with the FMF gnarly pipe, gave it alot more bottom and the the mid would not hit as hard. It sure was a blast in the dunes.

have you ever ridden or saw a cr500 in person? my uncles has a full FMF exhaust, new reeds, i forgot which air filter and a few other things, it is pretty crazy, its almost stupid because it has so much power its so hard to ride I think he took it to the drags and went 110 or 120MPH on it... crazy

[hawood]

I bored my cr500 out to a 650 and added a 30 horse shot of NOS, not a bad little bike for the tight tracks, could use a little more giddyup though.

[pro-rider46]

haha, i can only imagine a 500 two stroke, my 450 is probably to much for me, i would die on a CR500

[Kickstarts-suck]

My uncle has a KX500. They are just nuts! It scares me.

I used to have a suzuki dr500..Thing was a beast :p

[KXRida]

It's funny how they use the steel framed cr500 though... hmm I wonder which one handles better? :o It still seemed a little biased towards the 450. Anymore I'll ride any bike. 2 or 4 stroke, I just prefer 4 strokes now.

[Ruby Soho]

i think if the cr500 had the same attention the 450 gets and the recent updated it would be a better bike overall.

oh ofcourse it would. The service honda cr500 would've been a better comparison for that shootout.

i kinda thought the same but i just kept quiet, but you never know, you can get a 771 kit for a banshee.

[Duke Nukem]

I kinda think thats a lie too, this is the best I've seen on a 500.

L.A. Sleeve 540 big bore kit, FMF custom K-40 desert pipe, carbon fiber shorty silencer, Moto Tassinari V-Force 3 reed valve, White Brothers power filter, Pro Design Cool head with special 21 cc 15:1 Compression ratio dome, port and polish, stuffed cases, Wiseco stroker crankshaft kit, Vertex single-ring racing piston, Mikuni 42mm TMX powerjet Carb, DSP Power-Now Carb bore insert, Barnett dirt digger cutch, Splitfire triple platinum spark plug wiht 28 gap, 16/51T sproket combination, Redline fully synthetic racing oil, and VP Motosport 109 Race Gas. 106+ horsepower, over $13,000 invested in the bike.

something doesn't sound right there :huh

The power is only good when you can get it to the ground.

[Ruby Soho]

the one listed above, must have been a MONSTER:eek2:

[KXRida]

sounds like a flat out drag bike to me, but a high comp. piston in a 2 stroke? :confused: I dunno about all that. To me though, that would be a useless bike to have that much power. It'd be fun if I ran desert or drags, but for mx it's not even worth it.

[pro-rider46]

OMG thats crazy duke nukem. over 106 horsepower would scare the living crap outta me.

kxrida- 15:1 in two strokes arent all that uncommon, its not hi compression pistons in it. its the domes in the head that make crazy compression. my friend saw a guy with a 250r that almost didnt start cause of all the compression, and in 300ft it was doing about 80+ haha. but then he wrecked in practice so he left.

[pro-rider46]

here is a pic of it.

[KXRida]

You're missing the point. Two strokes don't have compression ratio's like that. They're not like 4 strokes. No such thing as a high compression two stroke piston. You can mill the heads, interchange heads/domes to acheive more compression, but it's not like a 4 stroke. Two completely different things.

[pro-rider46]

i understand what your saying, but some two strokes can reach 15:1 or higher.

[blasterfreak99]

my blaster actually has a 16:1 compression ratio. my piston actually sticks out of the cylinder when i take my head off, project blaster had to cut my head so the piston would fit inside it lol. im about to rebuild it as soon as my rings come in and ill take a picture.

and enlighten me on how you know it's 16:1? What fuel do you run?

my uncles CR500 has 85HP and its just a monster, it will wheelie in 5th and he can start off in 5th it has so much power and it spins the tires and digs trenches in 5th. I want to put a motor like that in a quad so you get better traction and something easier to stay on lol.

[pro-rider46]

foxhondarider, you can put one of those in a quad, but they arent balanced or something, and it will shred the frame, you need special mounts and all kinds of stuff. but it would be fun to do anyhow.

yeah i saw another guy on here with a cr500 in his 400ex. what do you mean it will shred the frame? and not balanced? like the quad now has more weight or less weight in the front or rear vs stock being pretty well balanced?

[Duke Nukem]

The engine isn't counterbalanced so vibration will shake things apart.

that sucks then forget that idea lol what i really want is to put the air cooler xr650 motor in my 400ex. it weighs like 8lbs less and makes more power stock than my 400ex could ever hope to have

[KXRida]

There was a guy that put a stock cr500 engine in a banshee. All that work and the 350 twin walked right past it. They're fast, but in a quad, not as fast as you'd think.

haha foxhonda... lots of bikes will wheelie in 5th gear and dig down lol. 85's will do that.

As far as the xr650... good reliable motors, nice smooth power, but not a great mx engine.

yea first time i rode a 450 bike at my friends house, i was going through the gears and in 3rd i gave it a little and accidently did a wheelie then did one in 4th and 5th no problem. thats when i decided im getting a bike:devil:

haha my 250F isn't like that. It does the normal first, second, third wheel pull, but after that it doesn't just come up. If I clutch it up a little in 3rd, I can bang the other two gears and get a 5th gear wheelie going.

hmm interesting, but dirtbikes that go over 100MPH in 5th gear wheelie other than a cr500? and I doubt 85's can dig a trench going 70MPH. the xr650 motor why is it that its not a great mx motor? its lighter than the 400ex and has way more power.

[Duke Nukem]

Maybe he thinks it's not good because the motor is too big size wise.

against a 450 race motor, now way would an xr650 have an advangate. Then again how many 400ex's do you see at the tracks anymore?

umm at a 70mph speed, no way is a cr 500 digging down that deep. Please. I've ridden cr500's and no way do they do that. 100mph? With stock gearing that's a stretch. :o

[Hondamaster5505]

You guys think 106 horsepower engine is crazy? Well get ready to chit your pants.

These guys modified a cr500 engine to have twin cylinders... twin 500 cylinders. That makes it 1000cc! They dyno'd it at 210hp. They sell this kit to the public too.

[KXRida]

yah there have been kits out for quite a few years that make the cr500's to the 1000's. They're monsters.
