I have a 2005 DS650 and my friend has a YFZ and he says that his YFZ will walk by my DS. I was just wondering is the YFZ Faster? If so by how much?

yes i have on a strait away maybe football fields length on gravel road. started in 1st and killed him 3 times a bike in a halfs length from start to finish. he was so shocked and pissed off haha. ds650's have a higher top end speed although i still beat him. didnt race him on the track but i know for sure i would of smoked him. it all goes down to if you can ride good.

I have a YFZ450 and I think it would not beat a DS on top end speed, no way. The 650c would scream more than the 450cc. Just my 2 cents

My friend has a 2002 DS 650 (stock). We drag raced approx. 750ft (2 1/2 football fields), 6 times. I beat him each time (w/ my stock YFZ) by a minimum of 4 quad lengths. He can ride pretty good & he's 50 lbs. lighter than me.

Then I added a pipe, jet kit & air filter... :hey: It's no contest now. 5-6 bike lengths now (that's after he changed his gearing. Down 1 tooth in the front & up 2 teeth in the rear. He also added a slip-on)

As far as top speed... I think the DS 650 would be a couple of MPH faster (stock for stock). We haven't checked it out, though. :shrug:

That's my experience

when my Raptor was just piped, YFZ's beat my ass all the time. And I've smoked every DS650 I've ever raced, stock, piped, mild motor work on DS, whatever.

i'd say a DS and raptor both could beat a YFZ stock for stock in an all out balls to the wall top speed drag race......i mean till all the machines hit the rev limiters in their top gears. :nod: :hey:

The Gearing your buddy put on his DS will make it slower that it was before. I calcuated it on the Bluetraxx Gear Ratio Calculator.

If you're referring to top speed you're correct. The shorter gearing will make his DS have a slower top speed. It will, however, give him quicker acceleration.

My point was, if both bikes have equal riders of equal weight, with equal talent, stock for stock a YFZ 450 will beat a DS 650 in an average drag race (300ft/ Football field). It is a quicker accelerating ATV. Now, if you're talking top speed (I don't have personal experience, this is just MY opinion), I think the DS650 would be faster.

Ask this question on a DS650 forum, and see what responses you get.
Exsactly, honestly I think the ds is faster, ive seen a yfz go, and ive been riding with a ds a few times. I think the ds is just a lil faster. But im not sure. I'd like to see a vid.
