Kastle calls the BMX 105 a “powerful freeride ski,” and, in our review of the former Kastle BMX 108 (the predecessor of the BMX 105), we pegged the ski as a “hard-charging, powerful ski” capable of “handling everything from powder to variable conditions with ease.”

Such remarks might be enough to lead you to believe that the Kastle BMX 105 is a close copy of the BMX 108. But the new 105 has certainly changed some — it incorporates different materials (said to be damper), more dramatic rocker lines, and a tighter sidecut radius.

Note: there is also a “HP” version of the BMX 105, and we hope to be getting on that ski soon.

So does the new BMX 105 live up to its heritage and its ad copy? Is it a powerful, big-mountain ski that really can handle any condition?

Initial Impressions

My first days on the BMX 105 were back in the fall on our review trip to New Zealand. Paul Forward and I both weighed in on the 105’s performance in our Flash Review, and we both felt that, while somewhat sluggish, it was a pretty smooth and stable ski in variable conditions. However, we also both felt that we wanted more control over the front of the ski. The shovels felt rather easy going or perhaps even insubstantial, at least compared to the back half of the ski. While Paul felt like this was improved by moving the mount +1 cm, I can’t say I ultimately ended up feeling the same way.

Other Blister reviewers then continued to get time on the BMX 105 over the course of the season, and to be honest, Jonathan Ellsworth and Mike Masiowski both struggled to identify where the ski really excelled; they both ended up feeling like it felt a bit out-of-balance in variable conditions and bumped-up terrain. So they sent the BMX 105 out here, to Colorado, to see if my initial impressions in New Zealand still held true. I’ve been able to get more time on the BMX 105 over the last few months and feel like I’ve been able to hone in on the ski’s strengths and weaknesses.

Flex Pattern

But before we get into the BMX 105’s on-snow performance, we should talk briefly about the ski’s flex pattern. From a hand flex, we’d sum up the ski like this:

Tips: 6

Underfoot: 9

Tails: 8

I.e., this is not that burly of a flex pattern, especially when compared to other 105-108mm-wide powerful, directional skis, like the HEAD Monster 108 or the Blizzard Cochise. In fact, it’s pretty interesting to find that the shovels of the BMX 105 are far more in line with The Metal by J Skis, which is much more of a “fun times” directional ski than the Monster 108, Cochise, or the old Kastle BMX 108.


The 2014-2015 BMX 108 had a sidecut radius of 33 meters. The BMX 105 has a sidecut radius of 23 meters. While this is a pretty dramatic change on paper, the character of the BMX 105 on groomers hasn’t really changed from our review of the older BMX 108. It still feels like a long-radius, big-mountain ski on corduroy. It’s not particularly quick to come around, nor does it have a lot of pop or energy out of the turn. On the flip side, it is smooth, stable, and planted through a carve, and is relatively unphased by piles of crud that tend to build up by the end of the day. While the Blizzard Cochise could also be described in this manner, the two skis behave somewhat differently. The BMX 105 feels a bit more planted and smooth (at least in the back half of the ski), but it lacks the grip and strength that the Cochise has through the shovels.

    • Hi Mikhail,

      I personally wouldn’t mount +2 because of the softer flex in the shovels. But I can’t say that you’d dislike it there? Depends on what you’re trying to accomplish, how you ski, etc.

  1. Nice you guys got time on this ski in different conditions and can compare to the BMX 108.
    I’ve skied the 181BMx 105hp, own a BMX 115 and fx95hp and had a BMX 108.
    Maybe the non hp has a less stiff tip profile because your feedback on the imbalance doesn’t fit at all with my impression of the hp. It’s flex reminds me of the most refind Kastle, actually forget Kastle most refind ski I’ve skied the buttery MX98 so I’ll be curious to see if your impressions change with the hp test.
    Second Im baffled by the on piste/quickness comparison to the BMX 108. The new 105 is so much more responsive and easy to engage on firmer snow. On soft packed groomers I can barely tell the difference between it and my 95. To me it’s a stellar frontside ski for its width. Other reviewers have consistently said the same.
    I’ll be sure to demo a non hp 105 in 189 and report back.
    Always enjoy your reviews!

  2. I’ve been eyeing the 2017 HP version of these since last season but wasn’t able to demo them anywhere. Does anyone know how their tips compare to the tips on the Volkl 108s? The Volkls had too much chatter for me…

  3. I have the 2018 189 HP and can confirm that the tips are pretty damn soft on them too. I don’t personally find them to be much of a liability when skiing in variable snow, but overall, this review is accurate. Given the disproportionately stiff tail and soft tip, you need to really stay balanced on top of the ski to ski them well.

    I’m no ski designer, but personally, I’d keep the shape and rocker camber profile the same, soften the tail 10%, and stiffen the tip 10%. Then this ski would be perfect.

    I wouldn’t want to stiffen the tips up too too much. Why? Because this ski floats incredibly well for a 105-waist ski, and I wouldn’t want to take too much of that away.
