I own a 500 Scrambler and have a friend that owns a 400...... The scrambler beats the 400 off the line every time, but gets caught and passed after about 50 yards..... I'm buying a intake, exhaust, clutch springs, and jets that may fix that. By the way, the 4x4 on the scrammy has come in handy several times while the 400 has to tug and pull his quad in the sand......

 

I just watched 2 weeks ago a modified 2000 scrambler 400 with clutch kit, HSP exhaust, and porting beat the brp 800 max on pavement by 2 quad lengths in 200 yards. (about 55 hp for the scram) a stock 400 will beat a stock 400ex in a drag but not on any race course.

 

say that to the predator

 

Seems to me that while your 400ex is scrambling for traction coming out of the corner, the 500 Scramber will be pulling with all four tires. The 500 Scrambler is going to be fastest when you put more corners in.. just for that reason. There was a write up in one of the rags comparing the DS650, thbe 500 Scrambler and the KFX700. The KFX came out last in the corners.. the DS650 and Scrambler swaped wins depending on the driver.

I guess Polaris does know something about handling. BTW.. the Scrambler has more rear suspension travel and equal front suspension travel than the EX.

 

Wow there really is a thread arguing this that has several posts.

Guys the Polaris is a 570 lb 4wd monster that is good at....ummm.......
<crickets>

Well I guess maybe it has good top speed. And it's probably excellent at breaking down. It is a Polaris after all.

The 400EX is one of the best all around sport quads ever.

If you drag race them I would imagine the 400EX will lose but in any other race it should be light years ahead. Try taking that Scrambler around an MX track. You'll probably be Scrambling to keep it from tipping as you two wheel through corners.

 

I have a mostly stock 99 sport 400 thats a 2wd 2 stroke 475lbs dry weight i ride with 2 stock 03 and 04 400 ex's in our winding hilly muddy trails i smoke them easy! when their up shifting and down shifting i'm wayyyy ahead wondering if their lost , they sit lower is right and get stuck in every big mud hole,they need to be in first gear going thru and the sports flingin mud 50 feet ! i pulled them both outta mud this weekend that i went thru easy the only thing i see thats better is their ability to wheelie at highr speeds (2nd gear over 20mph)

just my 2 cents

 

I don't ride MX tracks. I would guess that most riders that come to this site do not ride MX tracks. We ride real trails, with real trees, bumps, roots, rocks, corners and hills. So I am not sure where this MX stuff is coming from. To suggest than any one quad is the best in all terrain seems presumptuous. I would guess that the scrambler will have the advantage when it can put its 4wd to use. That will not happen only in the mud holes. It will happen in many low traction situations.

 

Scramblers are tall and heavy, but they can easily be ported and piped to outrun banshees. Still you still have a heavy and tippy quad. Exs handle OK, but they don't have much for power.
Drag race and mud - scrambler
anything else - 400ex

The handling on a predator isn't very good either.

 

I agree on the above but you obviously have no idea what your talking about on the predator.

 

The sit way to high in the front and they don't corner very well
