Why does my quad only go 60mph? stock gearing, 19" tires

cam/pipe/weight etc don't come into it .. they get you too max rpm quicker.. a lot quicker in many cases, but your top speed will always be determined by the max rpm / gearing / tire size, the only performance enhancer that will change top speed is an aftermarket CDI or green wire mod on the 06's that increase the rev limit.

There's an online gearing calculator online somewhere.. (it's called QuadCalc) that you can plug in your tire size / gearing and it'll tell you what you speed will be for each gear.. I've got it but it won't work on my Mac or I'd run it for you... when I was looking at gearing options 83 wasn't far fetched.. I've just come back from the desert today, I went from 14/37 to 14/39 (22' rears) and noticed a big difference in top speed on the wide open sections.. was better for the rocky technical bits though...

Yeah I knew that I was running the 83, and suprisingly it doesnt take that long to get up there oh and I do have the green wire mod..

With 14/36 it should do ~90... that is a lot of gear... probably takes for ever to get up to speed though

90 with 14/36. hahahaha! ok so 14/38 is stock which means he only went down 2 teeth on the rear which is less severe than going up 1 tooth on the front. Even going up 1 tooth on the front wont' give you 90mph.

if i see video of your 14/36 doing 83 on a gps i'll bite my tongue, but i don't it didn't do it.

His stock gearing is 13/38, so he went up a tooth in the front & down 2 in the rear.

Sometimes you don't know everything.

I personally have nothing to prove to you or anyone on this site... **** I don't have anything to prove to anyone on the internet at all, so I am not going to reply after this, but you must have a very fulfilling life arguing with everyone you can on the internet.

did i say my quad was amazingly fast? don't be a jerk, just because i'm giving it straight.

mine tops out at 74mph, that's the real thing down a straight road with several gps attempts. i've had 74.6 ,but never hit 75. that's not me saying "mine does 90 or mine does 83". that's what my quad actually does. stock gearing, 20's.

Im not trying to be a jerk am i calling you out on that your bike doesn't go 74? Why must you call someone out on there bike when its not yours to say what it can and can't do? My quad does 83 and i have nothing to prove to you, but have a good one man, we all should be on them now instead of these fricken computers! Well have fun with yours and i'll have fun with mine.
