differences between axis x and mod x??

post #1 of 22
Thread Starter 
i'm looking at some used skis and am trying to figure out what the difference is between these two model years of skis. not interested in cosmetic changes, only functional ones. thanks.

This year (02-03) K2 made some changes in the Axis line, but last year's Axis X and Axis X Pro models are the same skis inside as the 00-01 Mod X and Mod X Pro.

The main difference between last years Axis X and the previous Mod X's is K2 removed the layer that converted vibration into electricity (I forget what they called it). This was more of a gimick than a useful feature in the Mod X skis so its demise is not a real big issue. If you look closely at the Axis X you'll see they still have the dent in the top sheet where the gadgetty light went.

daevious, what are the changes to which you refer?
post #5 of 22
The Axis XP is wider than the Axis X Pro by quite a bit, and the tail shape on both X and XP is more rounded and a little more up-turned. I don't know what else they did, if anything.

negative, Ghost Rider.

Axis X and Axis X Pro didn't have the piezoelectric module, and received some minor tweaks to make them a bit more lively than their Mod-related predecessors.

Whether the average skier could notice the effect of removing the piezoelectric module and/or the effect of the minor tweaking is debatable.

Yippee-Yi-Yay, then.

Axis IS the Mod technology. The reports I'd seen said they only changed graphics, hadn't heard about the liveliness tweaks.

As for the piezoelectric dampener, I think that was no more than a clever marketing tool. I don't believe that a credit-card-sized, passive device could possibly generate enough force to affect the flex or vibration of a ski.

Happy Trails.

One important note of distinction between the Mod X and Axis X lines is in the K2 Logo at the tip. On the Mod skis, it was imbedded underneath the topskin, but was bonded poorly to the ski. Eventually, the poor bonding of the layers caused the tips to crack. I should know, it happened to mine. I have checked out other Mod's sitting around at resorts, and have noticed many of the same types of cracks in the tips. K2 was very understanding the first year and replaced under warranty the affected skis. Needless to say, I believe that the small flaw has been mended, as my AXP's have no visible cracks after a season of use.

Moral of my long-winded story: "If you are looking for a Mod, check the tips for cracks." [img]smile.gif[/img]

Wow, everyone's an expert...

There is no difference.

Same ski except Axis X has no piezoelectric but Banditman is correct about some of the Mod X tip cracking. But i love my little piezo light flashing at night, looks kinda cool, doesnt do anything but looking cool is half the battle isnt it?

OK- here goes...

The 99-00 (prototypes and early retail production)/00-01 Mod X/ MOD X PRO are essentially the same skis as the 01-02 AXIS X/ AXIS X PRO. The differences were the removal of the chip (due to contractual hassles w/ ACT, the manufacturer), and a graphics change.

Yes, there were material problems with the earliest version of the MOD series, resulting in cracking (as was discussed) but that problem was pretty much resolved prior to the 00-01 model.

The current (02-03) version of the AXIS X is virtually unchanged, except for a bit of rounding of the tail (as Gonz stated). OTOH, the AXIS X Pro, has changed significantly. Though it has kept it's same general construction, it has become much wider throughout it's length. Still a very balanced ski, it will provide more stability off-piste.

The greatest changes in our 02-03 line ocurred in the MACH S/ MACH G. Now called the AXIS XR, it keeps the construction of the MACH S, but by altering the side cut, and lengths, it now serves what K2 believes is a more dynamic purpose. It blends the snappy carving S with the stability and dampness of the G together in one ripping ski. For those who prefer a metal laminate, hard snow, carving ski, this is the one.

If you've got any more questions, just ask...
(Yes, I do work for K2...)

So you work for K2??? I own a pair of the Axis's and love the ski. I have not found any terrain that this ski does not perform well in. If you work for K2 mabye you can answer a question. I've been looking for some stickers to go on my car. Can you help me out with this or tell me where i can find some.

Vail Snopro:

I thought this year's Axis XR was the same sidecut and basically ski as last year's Mach S, not Mach G. I know the Mach G/Patriot GT6 sidecut was 103/65/91, while the Mach S was 106/64/95. This year's XR is 106/64/95, according to K2skis.com. Is this correct? Our shop ordered alot of XR's for the season, so hopefully you can straighten me out on this one [img]smile.gif[/img]

The side cut is going to vary, depending on the length of the ski, giving it a fairly consistent radius. The side cut measurements given in the brochures will be for the standard ski, probably a 174cm. Compare different sizes, and you'll find a difference.

post #16 of 22
The manager bought these skis, hoping to target them to high intermediate tourists that normally come into our shop. I have only skied the Mach S in a 167 and the Patriot GT6 in a 181. I know the Patriot was forgiving but stable, the Mach S was quick, nervous, and a carving machine. Personally, I don't think that a non-expert would enjoy these skis, as the Mach S liked lots of angulation, and neither like to skid. Both required energy to come alive. With that said, what length would be best for the high-intermediate/low advanced skier, a length that they could improve their carving technique with? Or should I just steer anyone who is not an expert clear of these skis?
post #17 of 22
I think you'll find that the XR's are more suitable to very strong/ expert skiers. Most intermediates might have a difficult time generating the energy to really use the metal laminate ski. In fact, you will find very few manufacturers producing any metal skis for intermediates.

With the lifter which comes with the ski, it is designed predominantly for high speed, groomed runs. You could take the longer lengths off piste, but thats where the XP excels!

If you are really looking for the intermediate market, look at the Axis Mod X(very high intermediate), the Mod X(solid intermediate), and the Escape series. And don't underestimate the T-Nine series for women! There are some great skis with alot of versatility in that line.

post #18 of 22
I was just looking over this and am confussed. When you say that the sidecut will vary with the length of the ski, what are you meaning? As I understand it the ski dimensions are 106/64/95 this = a 18MM of sidecut. The turn radius will change with different lengths but the dimensions of the ski are still the same are they not?

vail snowpro just wondering why k2 added the metal to the mach s to make it more like the mach g, I have an axis x pro 181cm that rails & a 174 mach s to play frontside with & in moguls that I did not get to ski last season due to illness, both with marker 1200 piston bindings, from what I checked on the mach s was one of the best skis for moguls not being a mogul specific ski also a ski to ski with the family with, my second choice to do this would be the atomic 9.18 180cm, with the current xr I would not even consider it because of the metal unless I didn't have the pros, not much fun skidding the pros down the mountain with a 6 & 12 year old & wife learning to ski.
thanks bteddy

ACX is the name of the company which make the Piezo units. At my store a few years ago we had a guy working with us who thought of himself as quite an engineer. He also thought it was a marketing gimmick or gadget. I wrote to ACX about this. Of course their opinion would be biased, but listen to this, Rio!...

They wrote back and told me to tell this co-worker to basically go jump in the lake. If the guy was any kind of engineer he'd know it was not a gimmick. They said the ski is almost a cantelever board. The ACX unit was placed at the stresspoint of the ski which is just in front of the toe.

The purpose of this unit was to remove the secondary harmonic vibrations which are bad for edge control and leave in the high speed vibrations which are good for edge control. Mechanical dampners remove everything and also become less efficient at colder temperatures.

The first units they sent to K2.... K2 sent them back and said to tone them down... they were doing too good of a job! There were many models: the 1,2, & 3 pack units and the 3 pack, tuned. If you saw the graphs on these you'd see an incredible attenuation of vibration with the 3 pack, tuned unit at mid to high speeds. The others atenuated less but over a broader spectrum of speeds. This left a lively ski at recreational skiing.

The info about contractual hassles is interesting. I didn't know that. I assumed that K2 found this Mod material was working as well and therefore deleted the ACX unit due to being redundant and also to realize a wider profit margin for each ski.

My Mod X has the unit at the tip, and it is very small. I doubt it does any good being so small and being way up there, but what the hey!

I remember a situation about a year ago when I was in a friend's shop. A married couple were in, and the husband was looking at the Mod X. He asked about the little flashing light, and I started using my university days mechanical engineering and physics to explain what was going on.
His wife started smiling and nodding.
He bought the skis, and as they were leaving, she turned to me and said "That was a very good explanation of the piezo electric effect. You know your stuff." The man then turned to me, and explained that his wife was a professor of physics at a local university. :
Thankfully, what I'd said was theoretically correct. Now, whether the ACX unit worked or not is a different question, but certainly the principles it is based on are valid.

fox hat-

Very good story. Thank you. As I stated K2 sent back the first units because they worked too well. concerning the hteory of energy conservation or energy transfer this is plausible. ACX says this mechanical energy is disipated as heat and light. Teh light part I don't know if that meant the blinky thing or not. If not, the blinky was just a show. I'm sure that mine on my Mod X's do nothing but sit there and blink. it is fun though. I don't think it does any good way up at the front like that.

Now... I gotta go fly in Flight Sim 2k2 and crash a few more times before we get snow here in Oregon.
