Has anybody got a chance to ride the new xc 500? A friend and I had
both planned to buy zl 500's next year as we have both been arctic cat
fans since we first started riding.I got impatient and decided to get
mine this year.Well he has changed his mind and just snowchecked the
XC.And now he's bragging about how fast and cool his new sled is going
to be.I told him he beat me on the lake but he'll never touch me on the
trails.Will the new polaris smoke the zl or not? And if yes does anybody
know a good way to bolt on some more low end.I want to make him wish he
had went with the zl instead because I swear By arctic cat and really
love My ZL.

I have not ridden either. I know of a few people who have seen/ridden both.
He will definatly not "smoke" you. Both sleds should be closely matched. You
should both have fun trying to better each other. Let us know how it really
turns out.

NO - you have about 9 more horses than he. Both sleds have excellent low end.

Don't expect the zr to "smoke" the xc on the trails. This sled has the same
chassis and handling as the xcr440 with more snot. The zr is basically an
unchanged , well zr. It's not in the same handling class as the sno pro. If
it was the nod would go to the zr. XC will however out muscle the zr. IMO
the xcr440 out handled the standard ZR's by a fair margin. Your ZR will
have more inside ski lift than the xc5.

Have you ran these two head to head? Who's HP numbers?
If so tell us more,,, The new xc 500 is one hot little machine.
I havent had a chance to run ours aganst the 500 cat yet, but
I think it'll be a hell of a run!

handle a ZR. I'm not saying the XCRs don't handle well but they don't out
handle a ZR by a fair margin. I ride with 2 XC700s all year and they have
more inside ski lift than the ZRs. You're giving this person a very biased
opinion to his question. Like Jeff said, they will be very close sleds in
the handling and motor departments.

First off, I Highly doubt that the ZR 500 has 9 more Hp than the XC
500, but that aside, The main difference in the sleds in my opinion
will be the broadness of the powerband . As this years XC 600/ ZR 600
comparison for example; Both acheive similar peak performance, but
the XC 600 motor is a much more relaxed engine for general trail
riding. ZR 600 is powerful but relies on constant high revs to acheive
its perf. while the XC 600 motor uses a lower reving broader torque
engine that privides similar perf, without being such a nervous/peaky
type engine. I feel that the ZR 500 and XC 500 will follow this
scenario also.
On the ski lift thing, I have to laugh at the heat Ski-doo took over
it for a few years, and now they all (except maybe Yammies) have
varying degrees of it. Although I never agresssively rode a Cat
before the latest ZR's came out, the current ones seem to me to have
every bit as lively a front end as the MXZ's and now the XC's too.
I don't see it as a negative really unless it is unpredictable.
..... Both the ZR 500 and XC 500 are excellent sleds, pick the one
with the best dealer.

The zr & the sno pro have the same basic chassis with the exception of
weight. The sno pro carries 24 less poundage. This is where the better
handling comes form. If you haven't ridden a sno pro it's a must do. The
xc6 &7 have a different motor placement than the xcr440 & 500. The motors
on the 440 & 5 are sunk about 1 inch lower than then it's big brothers.
This makes a huge handling difference. ie; flat cornering. I've been in
touch with a fellow who has raced the xc500sp in a late season 500 mile
race in Alaska. He walked on all 440's and 500's. The sled was box stock
without as much as a jet change. He reported that the 500 was 1 mph slower
than the sno pro. A well cared for sno pro will consistently out run a zr5
by 3-5 mph on top. And yes I did run a xc5sp in late January. Sneaky fast
is my impression. Rode the zr500 also. My money is going to the xc.

Ive got a problem believing the implication here. Who is going to run a race
sled box stock in a 500 mile race?!? Regather your facts and tell us the
name/place of the race, who your buddy is, what class he run, and what place he
came in!! Untill you produce this info, a statement like that gets filed with
UFO sightings (and performance benefits). No massive flame intention here,
just a reality check.

Michael,

Even you can do the math. See if you can follow me....Old Indy 500, ( did I
say OLD) is 75hp, ( some would like to think 80, sorry, no.), Polaris says 18%
increase, ( Hey, i'll use to WHOLE 18%), this gives 7.5hp increase.
75+13.5=88.5. Cat says 95 for the 500, ( I'll use the whole 95) So....
95-88.5=7.5. Guy below says 9 difference, for 2.5, I'll call it close enough.

Maybe fun to speculate who will beat who, but really is no more than worthless
dribble until we see next season, right?

Markus.

Never have I seen a zr5 dyno at 95, never. 5 pulls with the zr5 and saw
91 max with a very hot pipe. An engineer in the know speaks of the xc5
having an output of 92 cold pipe hp. hmmmmm going to be close.

"YOU" have never seen?, "Engineer in the know"?, ( are there some "NOT", in the
know?). Sounds like stuff I can bank on, "FOR SURE".......Lets keep our
panties on and wait for them to meet (ZR,MXZ,XC), grass or snow.

Yeah but my Mxz 670 is "suppose" to have 115-118 hp yet it is close
between my sled and my friends ZR 600 which has 103-105hp, and on the
very top end I think my ZR 580 97hp would keep up to my Mxz, have to
wait until next winter to find out though, unless we get a blizzard. So
horsepower numbers don't mean as much as people think.

But that's stacking hype on hype... :-)

I guess I wanted the real numbers when I asked that. We'll see if 9hp is
really true.

Hp figures are good only for bench racing. If they are reasonably close, the
only way to determine which sled is faster is to race them.. Even then, the
condition play an important factor in determining the outcome. Buy a sled for
yourself, your tastes, and the intended purpose. Dont chase newsgroup babble
(remember the SRX700 would beat those XC's...I rest my case your honor).

They also rated the xc6 @ 109hp and the xc7 @124. I haven't seen these kind
of figures either. Wish I could claim this cause I'm a BIG polaris fan. Oh
well. ZR5-95hp.........no way.

The dyno readings am snow did are IMO highly inflated. The xc6 @
109---xc7@125---Wish it were true but never will happen. This isn't the
results I've seen.

Which in itself calls into question the practice. You do know all 98 Doo
500's had severe tuning problems don't you? Given reports of 70 mph top
speeds (before update) I find it very unlikely an out of the box MXZ turned
in that number. Tuned & tweaked perhaps????

Now should we trust any number?

Arctic Cat lists hp figures right in there brochure. The ZL500 and ZR500
are both listed as having 96 hp. I have the brochure here if anyone
wants to know the ratings of other Cats.

Michael;
I agree, they must have found the only one with the
proper rotary valve etc . ;-> Will be nice when we start seeing
dyno numbers @ the crankshaft and also rear axle. One of the sled rags

said there was a rear axle dyno out now, wonder why we haven't
seen/heard more ?! Would be great to see who has the most efficient
transfer of power to the snow, and the amount of power lost in the
transfer.

No flame, but just what were the results you've seen? Whose dyno?
Corrected or uncorrected HP? How old an engine? Stock or 'modified'
jetting? Enquiring minds want to know!

heads saw 144. never have run one with pipes alone but what i've seen it's
a waste to pipe a xc7 without porting due to the low exhaust port design.
The 600 saw 104hp. These figures are all with warm pipe and engine with

hp without tinkering other than jetting. Can't believe Cat is still

Okay Here is the quote from Bob Nygaard.." 5 more than the next biggest liar"
Got that? HP is WORTHLESS in his opinion due to the measurement basis.
Performance is everthing and Polaris sleds PERFORM !
