weight of a rider

[KAWSAM62]

question for all if two 400exs were built almost the same as far as engine mods and they raced with one rider 230 pd and the other rider 180 pd what would be the diff in quad lengths at the finish running full throttle thru all the gears, would the lighter rider always win? would the weight always be the deciding factor this is on clay road. tx in advance any opions welcome

Well weight is the deciding factor of max hp you will get out of it on top end, so yes it does matter. 40 pounds is enough to loose a few. (1-5) Im not a math matician, so I hanvt tried and set it up.

[KAWSAM62]

so it would be safe to assume if a heavyer rider was staying a solid 2 quads back through ever gear then that 400 must be making more hp then the lighter riders 400 cause hes not walking away right?:confused:

[wilkin250r]

the lighter rider SHOULD be able to accelerate faster, but it shouldn't make much difference in top speed.

So basically, the lighter rider will pull ahead, maybe a quad length, until topped out 5th, then stay ahead, but not increase his lead. Theoretically...

[bigsho400]

it depends on the rider period the better rider is gonna win in the race. i beat some of my friends banshees consistently and all i have are little mods. no 440 kit nothing of that sort. stock banshees are way faster than 400's modified or not

[wilkin250r]

Shifting gears properly will make more difference than 50lbs will, if the quads are theoretically the same.

Let me speak from expereince here. I'm 240 and race many smaller people from 160-190 pounds, I have nothing special done to my quad, I have found it works in my favor most of the time. when some guys come off the line there wheels are a spinnin, I use my weight for traction and to hold the frontend down, but it hurts me on some straights when we are already moving, coming out of a turn, but I agree it depends on rider and machine, alot of times through the trails we are right next to one another, moral is weight avantage or power is no match for skill(I have nether)

I also am a "well rounded" old guy and a I ride with a buddy that owns a Z400 which on occasion I am able to whip up on. Bone stock he could consistently take me by 1 1/2 - 2 bikes. But on paper the Z400 is quicker! So the short answer is like most have already related, SKILL is what will win. I now have W/B E series slip on pipe, stock jet and no air box mod and I can now take him when we get wide open out in the sand, but it is not very much. Seems my 40 plus pounds that I have on my buddy allows me to hook up better off the line, not always to my advantage. In the woods it is all about stamina. We have also switched bikes and I can usually take him and beat my own bike, argh. So the final answer after all of this rhetoric is. Consistency and rider skill will do more for you than simply weighing less. If we really knew what the key was we would go out and buy 2. Just incase we lost one.

MMMM Maybe its just the rider...... or is it I'm just faster than you
:blah

Also you are running a 15 tooth sprocket and I'm running a 16
:devil

[speedy400]

well I've proved it for you,
Last year I was at the ice drags. I raced my dad's friends super modded trailblazer. He was about 1 or 2 mph slower than the guy in 2nd for that section, all you have to do for that quad is hold the button down. So I raced it about 2 min after he did and i got him the second place trophey!By about 1 mile an hour.

oh yeah he is about 190-200 I am 120lbs

i think weight meens alot if both riders have about the same skill ,but most of the time skill wins the race not weight...

[EricB]

yeah with aceleration your gonna get hurt some, in a drag race on equal machines you'll get destroyed asuming that both riders are pretty close in skill. but as far as being big and racing it doesn't really matter if your good. i know i can smoke people on the trails on my stock 400, i'm 255 hehe. i tear up my buddy who is prooly 140ish? total guess there, he's pretty small. anyhow i tear him up on his 02 yz125 and on his 99 banshee i don't know what pipes he has, stock head pipes and some aftermarket silencers.

honestly all this talk like 90%rider 10%bike stuff is kinda BS imo when your just drag racing. unless someone can't shift or is missing shifts it's all about the speed of the bike. unless we're talking hardcore drags. but just like to see whos bike is faster it's mostly bike imo. because my 400 is simply not as fast as a z400 hehe. i got blown away 3 times consecutivly a few weeks ago. then i spanked the guy with his z when he was on the 400. an i'm guessing the guy was arround 180ish prooly too. just blows me away from start to stop really. but we were pretty evenly matched in skill i'd say. no missed shifts or anything. but i do have to say the z is fun to ride, but i do like the 400 still.

Every 10lbs you can shed theoretically adds 1hp.

Power to weight ratio

[KAWSAM62]

hmmm well see y2k400 but shouldnt the 15 tooth front get the hole shot over a 16 tooth front sprocket? and if the gearing is diff why stay exactly 1.5 quads behind thru all the gears i mean gear ratio wise the lower geared quad should have reached top speed quicker right but we were dead even1.5 quads back except for second gear were he gained the length on me:confused:

[y2k400ex]

With the 15 tooth you could pull stumps, the motor will rev out quickly. The 16 tooth takes advantage of all the low-end of the 400.

I still like the saying'' youth and talent is not match for age and trechery'' let hear it for the half skilled fat guys!!!!!!!!!!!:macho
