heyy, i would like to know what the fastest stock sport quad is and if you know anyone thats pimped out a sport quad how fast is it??? any quad ever made from the factory and hit 85 mph let me know thx

My pred stock was speed matched to a truck at 83 and radared at 85 down hill. I know 450r honda TRXs pull away from me on flat so they must do over 85. I got a bigger front sprocket and it should do 90 according to the gearing charts for a stock pred and mine is far from stock. You will never have a chance to open it up to that unless you ride the roads thats how I got mine going that fast on roads and one stretch of trail we ride.


EDIT: The ds 650 possibly has the most parts for it motor wise I bet you could get that thing to do 100 with no problem just change the gearing alittle anything can pull 100 just how long will it take to get there and will it hold together but its all in gearing. DS though would probably be the best bet if you wanna go fast in a straight line that is probably the one with the most mods out there that I can think of. Nitrous is always nice.

Well, I know that they are claiming that the new Polaris Outlaw KTM 525 is the fastest accelerating stock sport quad on the market...I have a Polaris Outlaw 500 and I clocked it on the highway at 80MPH, and that was before my mods so I don't know what it will do now...Once I get home from work in a few days I will have to see.

Here is the truth. The fastest top end fourwheeler on the market right now is a raptor 700r. They will truthfully only do 78. The yamaha, honda 450's will do 75-76. a Ds 650 will do 76-77. A predator will do 74. A outlaw 500 will do 72. A banshee will do 72-74. A z400 will do 68. A ltr450 will do 68-69. A raptor 660 will do 74-75. A 400ex will do 65. A raptor 350 will do 62. A warrior will do 60-61. A 250r will do 68-69. A lt250r will do 69-70. A tekate 4 will do 70. And the fastest quad stock ever built was a quadzilla lt 500 from suzuki. They would do 80-82 stock. These our all dead on accurate. All mags will agree with this also. Pretty much sence the zilla quads arent allowed to go as fast as that one did. And i think the outlaw 525 does 76 from what ive seen/heard. That is the only one im unsure about. Ive noticed most radar guns show different mph than other. So a car is kinda the best bet, but they arent always right either.

The 450's deffiantly have the most motor and modifications available to them. Sence they our race qwuads and people our always looking to spend on them. Then the 400's also have more than a ds650 sence they our the most popular choice. Actually a ds650 really doent have to much choices compared to most of the atvs out their. If you go threw a magazine, they will usually list yamaha, kawi, suzuki, honda. You dont usually see brp, ac, polaris/ktm atvs as much. Unless it is predators.

You would think that too that race quads would have the most since they are usually all done up and the posers do them up too. But I mean serious kits big bores whole motors u send in and get back completely diffferent, nitrous. Before about 2 years ago DS 650s were definitly to me the most modded options because people got into them so huge and went ALL OUT. But ya now you dont hear much about them people started doing engine swaps instead of dumping motor into a stock.
Before all these other 400s and 450s came into the scene i think the DS was the most moddable out there.

thats pretty accurate on the speeds I think.. I have a modded 86 250r atc that fly's past my 450r on top!!! when you start getting over 80mph on an atv,your movn'...especially a 3 wheeler with the nose in the air!!!

I agree here, I had a Banshee with FMF pipes and it did 78 on the gun down a road, same day same radar the 660 Raptor went 72

Yea banshees exspecially scream once you get into their motors.

i race for honda so i obviously think that the 450R's are the best....AT THE TRACK the hondas and the suzuki LT-R 450 are consistantly the fastest quads. the yfz 450 handles well (i rode yamaha 2 yrs ago) but is not the fastest. a couple guys have gotten onto the KFX450R and they are right up there and are pretty good. the fastest sport quads at the track and on the trails are 1) Honda TRX 450R 2) Suzuki LT-R450. i have seen the outlaw 525's run and i dont think the are faster that the 450's and the numbers that i have seen dont show that they are faster. watch out for that KFX450R though

My Raptor 660 on pavement went 72 stock, 75 piped and jetted. My wife's YFZ450 piped and jetted will stay head to head but she will leave the hole much quicker. 8omph or higher stock seems too much due to the fact that some manufacturers decreased the top speed of their quads to under 75mph to meet CPSC (consumer product safety commission) demands. You can regear most quads and easily exceed 80mph but it can be quite unstabile at that speed and the clutch has to be modified. The quad that would do the best at high speed would be the older DS650 which was longer and wider that the new ones.

tell ya what, that 05 450r of mine is scary fast back in the woods, handles nice and more then enough power. Everbody gives me a hardtime for keeping it stock but truly has more then enough power in the woods..besides if i want to drag race I've got my built 86 250r atc for that.

I'm really happy with these new 450's. I never thought the 2 strokes would get replaced but these new liquid cooled 450's are fun, deceivingly fast. it sure was a long wait for them to come up with a 250r replacement,though..but damn,look at all the action now!!! reminds me of the 80's. very exciting

Top end

DS650

Top end

Lt500(quadzilla) not DS 650

Wonder what mine will do top end? Better go get it radared. LOL!

agreed

Love to see the two of these race though.

zilla would kill it


and the raptor 700 is faster than the ds, and the yfz will run pretty much with the ds

I ride with a raptor 660 and a DS 650 both ae bone stock and the guy on the DS is tiny and Ive personaly watched the rapturd pull out and pass the DS and just barly creep awaydown the road for a long way.

Yea ive seen the same, my yfz creeps past the 660, and my friends 700 creeps past me.

i know for a fact the 88' quadzilla did 98 mph's out of the box stock. and with a little gearing, cool head dome, and some other things she does 105

my 01 banshee w/ 16/40 gearing CPI pipes,D&D trail port,D&D cool head (93 octane),v-force 3 reeds,K&n air filer (no snorkel,holes in the lid) 4 mm Stroker w/ 5mm long rod ran 99 MPH on radar. lookin to break 100 this summer!

I never checked the actual top end of my 05 RAPTOR 660, but my seat of the pants speedo says 70-75 mph. I did check the speed of my 84 Kawi TECATE 250 back then along side my ASPENCADE...Top speed was 76mph.

I've read about 120+ hp (extremely modified) Banshees that can reach speeds close to 120 mph.

I've seen both Banshee and Quadzilla quads that had a Polaris tripple in them run at dirt drags.........that was cool

the majority of these posts are complete BS

I agree........... but unless ya want to add something usefull.

"my 01 banshee w/ 16/40 gearing CPI pipes,D&D trail port,D&D cool head (93 octane),v-force 3 reeds,K&n air filer (no snorkel,holes in the lid) 4 mm Stroker w/ 5mm long rod ran 99 MPH on radar. lookin to break 100 this summer! "




that was on pavement also not dirt

This is very accurate for bone stockers

ok i will. my 84 tecate 3 w/boyesen reeds and rejetting would do about 55 with stock gearing and tires. after a pipe and taller gearing(much taller) it'd do low 70's. stock vs stock the tecate was the slowest of the 250cc 2 stroke trikes, with the tri z being the fastest(only about 2mph seperating all 3 though). quickness might be another story... a trx 250r has about the same top speed as a 400ex, stock vs stock, neither is impressive. cannondales(speed/moto) were pretty fast for stock machines. and i believe the lt500(87) was the fatsest stock production 4 wheeler, but in stock form it wasn't as bad ass as you'd think it' be.

stock machines are geared extremely low to be doing top speed runs. and for liability, reliability, and environmental purposes they're in a mild state of tune. and always will be. magazine tests(dirt wheels is the worst) are about as accurate as the things spewing out of the presidential candidates mouths.

the 86/87 tecate 3s were the fastest trikes then 85/86 atc 250rs then last the tri-z's

i disagree.

hes right with that my honda was a tad slower than the tecate my buddy had two very ugly. fast in straight line only i would always be in front as the kawis didnt handle.

I think the Quadzilla is the fastest stock, the fastest modded = how much money you have. I've seens Turbo DS650's, the Alba Raptor, and Banshee's modded, all depends on the $$$.

The fastest stock quad ever would be the 1990 Quadzilla. They have an extra head bolt so they gont blow gaskets. The ATC250R is the fastest 3 wheeler from what ive ridden. The '86 R's rip. There crazy. I had a 660 raptor with a 700 big bore kit, stage 2 hotcam, porting, big valves, 13:1, and bored carbs with an FMF exhaust. I clocked in at 94.4 mph with stock gearing. It was crazy. Sold it to buy sled. The funny thing is, They both pulled the same on the bottom end. The 250 2-stroke quads are all in the low 70's. The banshee is around 75-77. The 250 3 wheelers are high 70's low 80's. The new Thundercat 950 should be a interesting quad. They say 80mph. Id like to ride one of those things! The DS is a stupid quad. There ass ugly and everyone thinks there amazing. There not. There fat bastards. They feel heavy like a 4x4 quad. A waste of time.

Probably not considered a sport quad, but what about a Renegade 800??

01 banshee pipes ,reeds, 86 on gps before I started going up a hill on short stretch of tar. I think she will do 90 if given a 1\2 mile stretch.

current fastest sport quad bone stock- Polaris Outlaw 525s or ktm 525xc period!

1 extra head stud doesn't make anything faster... the 87 zilla was the fastest of their breed. in 88 they added the extra stud. yes, can ams 800's are way too fast for their chassis, at least the outlander is, never rode the renegade.

800 gade by speedo-75mph. 500 zilla was fast but junk and not that much faster than a shee. zillas didn't handle for shit!

Yeah whatever, a 500cc 2 stroke against a 350 2 stroke. Both nweight about the same, hmmmm, I wonder who is going to win? And why are the 87 quadzillas the fastest?

Definetly a '93 300TRX...I've seen upwards of 45mph. & that's all stock!

03 predator would do 73mph on gps nearly all the time. Geared down 1 tooth on front 68mph. Plenty fast for a quad in my opinion. If you need a half mile to get up to speed you dont have enough power.

two of my friends had a stock o4 yfz450 and a stock 03 raptor 660. We ran them on a gps and got 68mph from the yfz and 72 out of the raptor. The yfz would get there much faster then the raptor would though.

So would I :-)


My Banshee beat my friends quadzilla 500..Barely.. The 500's just don't stay together.. They had lots of cylinder & cylinder head problems, thats why they added the extra bolt. My DS 650's will beat my banshee, but the banshee is a little faster off the line. The DS is heavy, but they are indestructable. Heres some pics of mine.. an 01, 04, & 05. And the banshee is a 95.

ok, lets line a zilla up against a rz350...

cc's, horsepower, torque, blahblahblah, gearing is what dictates top speed or quickness. so a 350 could easily beat a 500 if it was geared higher. in 88 suzuki switched to case reeds for the zilla, thus different porting and flow characteristics. my old 87 was as reliable as a tank, never had any problems with it. #1 problem with any 2 stroke is the owner.

So your telling me that if a 50cc quad had the same gearing as a Quadzilla, and they raced, it would be a tie? yeah, sorry bud, but i dont think you know what your talking about.....

86' trx 250r with a 91' cr 500 motor in it. seems stock to me!

Ya just about nailed it there Nytro. Pretty close numbers for equipment that was built 10 years before you were born....Good Job.

A little history of the ATV

In a prior life, like 25 years ago, I used to be addicted to 3 wheelers and quads. I have just about every 3 & 4 wheeler magazine offered from 1979 to 1990 in boxes in my shed. I pull them out every now and then and cry because of what the CPSC and the Environmentalists did to that once great sport. Its really good to see it come back so strong.

I bought a new Honda ATC250r 3 wheeler every year from 1981 to 1986 and then switched to the TRX250r's from '86 to '89. Still have a showroom mint condition '86 ATC 250r and TRX 250r. My brother jumped into the game in '85 with the lt250r and bought new sport quads every year till '89. He had several Zilla's. They were definately the fastest but like just about all Suzuki toys at that time had serious durability problems, and I'm not even considering the head gaskets. The rear axle and chain adjuster mechanism was a joke. Brakes were a complete joke. And we were replacing pivot bearings every few months of hard riding.

Todays quads are finally (last few years) coming around to where we were in 1990. If the 2 stroke quads were to have evolved like the MX bikes the 2 strokes would likely still be right there with the best of todays 4 strokes.

FWIW. The '88 Quadzilla was radar'd at approx 79mph back in the day. It was considerably faster than my TRX's but wasn't even close on the race track or in the woods.

Also. I always remember the Tecate as being very quick but the 5 speed gear box held them back just a little on top speed. They were tough and hard to beat when they had a good rider on them. In my area the TriZ's were never a match for the Honda or Kaw.

I know it's an old thread but it's a good one. Thanks for bringing back great memories.

The only numbers I disagree on is the banshee numbers. I am certain they are the fastest production fourwheeler ever made next to the LT500

what about the new t-cat? 77hp and 165tq stock

There is NO way in hell the Thundercat has 77hp and 165 Ft lbs of torque. NO freaking way. I have a mod 1100 doo triple that maked 220 HP and only 147 Ft lbs.
