How fast would a 05 450r be with a +3 stroker a13:5:1 pistion a hotcam stage 2 a led exhaust and a k&n jetted carb be as in mph

Same exact speed as bone stock.

Gearing / Tire size / Rev limit control your top speed, not the power of the engine.

The power just gets you to the top speed faster.

as john said, people always think cause they got a buncha motor work and parts that they can now do 90mph. a stock *** bike will be able to keep up (in top speeds) with a fully modded engine bike if they have the same gearing, the motor work jsut helps u get there way faster hence it seems like the bike is super fast, and prolly is depending on how much motor work u have.

Would it be possible to brake 100 mph

It's almost impossible to hit 100 mph on a quad. The'res simply too much drag & not enough horses available. I've gone 91 (measured by vehicle) on HIGHLY modified Banshee, but it's gonna take a MEGA-BUCK four stroke to do that.

Quads in my opinon are not made to go that fast. They are ATV's you can't go 100mph's in the desert,trail,woods.

turning even a little bit feels tippy at just 60mph on a road(not that I've done that before;) ). I can only imagine what 100mph feels like...

What's the fastest I can go with the set up I am doing

I always wondered about this myself as well, when the magazine gives the stock speed of 74 or whatever it is (old DW shootout of 04 YFZ/TRX) is it aerodynamically limited, or does it pull the limiter fairly easily in 5th gear?

because my girlfriend used to have this piped YFZ and it felt like id haul *$$ in 5th, and I know its a tooth down in front. so if it could pull the limiter stock then I wasnt going anything near 75.

we broke 3 digits on a raptor 660. 720 big bore and a few other mods. extremely small rear sprocket and a big front one. slow as hell until he got it goin. i say we did it but all i did was install the fox flats, american racing tires, and change up sprocket and chain. another friend rode on a streetbike next to him and got the speed.

after hi did it he said he would never do it again. it was stupid.

like I said, as fast as any stock bike with stock gearing and stock tires.

thats about 81.4mph but with wind resistance and drag your looking at mid 70s

ITS ALL IN THE GEARING. doesnt matter if you have a 70 Pro mx RAGE bike and a stock *** 450r, if both have the same gears and tires both will do the same speed.

I built a banshee about 8 yrs ago. It was a 570 stroker. I did a lot on modifications. About 12000-13000 in the engine alone. Built it for asphalt racing. Playing around with the gearing and a long staight road I got 128 mph with a radar gun. I've also blow a tire off the bead a time before with the same bike shifting into 6th. The bike was definitly a death trap, I was just lucky. After that its got beadlocks all around. anyways
With the mods you have I would exspect 85-90.

Only if he does a massive gearing change.

I don't care if you get 400HP out of ur R engine. If it has the stock rev box, stock tires, and stock gearing. It will not break 72-74mph.

TitanMotorworks
02-12-2009, 08:54 PM
yes I agree 100%. I must have missed it that he was running stock gearing. Just going up 1 tooth on cs on a stock bike runs just over 80

02-12-2009, 09:29 PM
I have a rev box and what gearing should I go with with so much power

maddmatt02
02-12-2009, 09:33 PM
try going up one up front and down two in the rear. you could probably just go up 2 in the front and still be fine but you might want more low end, also not sure how large you can go without having to ditch the case saver. so then youd go up one in front and down about 4 on the axle. do you have any spare sprockets laying around at all? I know my old boss had about every honda sprocket you could wanna run.

andrew24
02-14-2009, 03:50 PM
No spare sprocets

maddmatt02
02-14-2009, 04:11 PM
Id say research to see if you can run a sprocket 2 teeth larger up front and still run a case saver, if not just go with one tooth up, but definately do that, and if its not enough drop a few out back.

I rode a 460ex, 11:1 was all, with a stg 2 cam, and it was up one in the front and down two in the rear and it pulled it easily, probably could have gone even higher, but top end was fast enough and the low end was nice. with +1/-2 F/R you could get going damn fast, especially if you got an extra 1k R's . depends on how fast you plan on cruising at, if I hit 70 occasionally I wouldnt gear up much, but if I planned on doing steady 65+ cruising through the desert Id go up quite a bit so I wasnt sitting at 9k steady.

I think with high enough gearing and a long enough road you can push a quad to go 100mph. Different motors and i'm pretty sure you can get there (cr500 or xr650). I wish my friend still has his quad all built up I would have boughten him sprockets just so we could do 100mph on a quad. It did 86mph so I think another 14mph would have been possible

maddmatt02
02-16-2009, 07:32 PM
I think theres lots of quads that could do it without swapping engines, all the 450's ktm/pol. 525's pred 500, ds650, raptor 660/700, kfx 700(dont remember gearing options on that one though), probably even very highly modded kfx/ltz 400's or 400 ex's.

sure theyll all take work, and some longer roads than others, but you definately dont have to swap engines to hit 100, you gotta have a nice road and some balls.

02-17-2009, 03:20 PM
I have a road near me its a loop at the end no houses just woods along it. Its over a mile or straight road. I mean straight, if you had a good car alignment I bet you could go atleast a mile without touching the steering wheel. On pavement I can top my quad out real quick. On pavement I usually find myself pulling the clutch in to hit another gear that isnt there.

iv been 91 on my 07 with a hand held GPS i dont know how accurate that is, that was befor the piston or head work and with stock gears and 20s and i ran out of road but still wasnt hittin the box.. its kinda hard to lok at the gps and the road

maddmatt02
02-18-2009, 07:28 PM
so then that answers my question finally, stock top speed of a 450r isnt electronically limited, its areodynamically limited. so if you can hit 90 with mods on stock box/tires and still have room to go, I might have gotten going pretty damn fast with a modd'd 450 with a tooth down up front.

I know my uncles handheld gps is accurate, not sure about them all.

Unless its a 1/4 mile or longer strip or it has a turbo, Im calling bullsh#t on that one. On a long stretch I could see it. But in a 500ft dirt drag, it aint happining. My fully decked out zilla on alky wont pull 90 mph at a drag strip, let alone 100. I have never been beat by a 4 stroke yet. On a longer road and the right gearing thats a different story

my cousins 07 450R with HRC kit and HMF slip on hit 86 mph with a garmen gps in his pocket. that is with a 13t front sprocket and 20 in tires. imagine if he put 22in tires and a 15t sprocket on the front, i'd bet he could get in the 90s! does this seem normal for a 450r or does he just have an abnormally fast one? lol im being serious....

one good thing ive fond useful with all this high end speed is wen the cops try and pull you ove fr driving down themain street of your town on a one wheeeled wheelie all you gotta do is get er back on all four and hey havent got a chance hehe

03-01-2009, 10:41 AM
Fenders do add resistance so take them off and try it lol. I'm serious just put the seat on and try your top speed run.

It,s all gearing! the guy that said 13 tooth front and 20in tires way off 86mph maybe 70mph now if he had 15 /40 and up gearing 22in tires I can see 86mph alot of desert quads go in 80-90mph but thats about it if more would have no acceleration at all.

don't get me wrong ,i like going fast as any one ,but aren't the tires only like 2 ply ,...........thats not the tire to go that fast on.

I can't believe all the action this one post is getting?Sounds alot like the salt flats on here instead of off road atv's!
What's all the excitement about top speed?Its about who gets to the finish line first.Handling,riding ability,reliabilityand power get you there.Not top speed?
When is it ever top speed on a quad that wins on atv off road racing?

that will not get over 80 flat unless you have got different gearing.

I had an 87 zilla and sold it a few years ago.I'am sorry I sold it.
80 is fast enough.Always can change the gearing if you want.Thats the nice thing about a zilla.There is always plenty there if you want more!

When is it ever top speed on a quad that wins on atv off road racing? Not everyone is a racer. Some people like to hit 5th gear pinned down a straight away. It is fun to open a machine up.

Oh I agree but lets face it atv's are not set up for top speed nor is that there purpose.
Nobody likes to go faster then me.So when I get the urge..which is quite often I take out my blown 32 ford and really get my jollys off.I leave the quad for off road riding.

I'm with you, the only time my quad sees pavement is from the garage to the truck. You are right, quads are not built to go as fast as their counter-parts with 2 wheels.

I agree, Its about acceleration, not top speed. If I wanted my zilla to do 120 it would do it, at the salt flats with about a mile stretch lol.

Thanks for the compliments on the zilla guys, shes not even my favorite. Here is my baby lol. Found her about 13 yrs ago rusting away, motor full of water, sitting outside for 5 yrs

Baja quads are like SuperMoto quads ... they have incredibly powerful engines with a lot of torque and horsepower to get them going (acceleration) but it's the gearing that gives them their top-speed. The difference of course is that a Baja quad must be bullettproof reliable compared to a SuperMoto racer.

To increase top speed, you must either increase the size of the front sprocket, or decrease the size of the rear. Generally, there is a 1:3 relationship between front/rear.

Personally, changing gearing one tooth here and there is smart, as you are adjusting the quad's performance to the riding conditions (MX track versus open desert for example). Going to the extremes to see "how fast" you can go doesn't prove anything.
