I'll buy an A* back protector which will be okey with A* kr-c chest protector. Actually my main purpose is lower back coverage, because I injured my L4-L5 (lumbar vertebreas) 2 times (1 crash 1 lifting). But can't decide between Kr1, Kr1cell, Kr3. And have 2 question marks. 1- Size chart suggests M, but I want full coverage on lowerback. So I wonder any problem occur if I size up to L (like it stretchs to the helmet) 2- Cell is new technology, new is always better? Kr1 2015, Kr3 2017, Kr1cell 2019. I can't decide how much I want kidney protector but protection on Back&Lower back is important me, so I can give up about it if Kr1Cell is best about protection.
The size large will use a larger shell than the medium. Here is a link to the size chart which will show which size uses which shell: www.sportbiketrackgear.com/product_images/product_pdf/Alpinestars-Nucleon-Back-Protector-Size-Chart.pdf
Nice video. I think to buy a new Protektor. What u will prefer from alpine Stars? Ne nucleon kr 1 or kr 3? Or maybe the dainese manis d1? Best regards Sorry for my english (because im a german) 😅
I got it for a year thanks to this review. But is there a correct way to clean it? i couldn't find any video as how to clean a motorcycle back protector.
I would suggest using a wet soapy rag to clean followed by a wet rag to rinse then line dry. You could also spray a little Lysol or something similar on it if you like. - Van
It would help for sure but it will be much more effective under a suit or a jacket. The jacket or suit will help to hold the protector in place and protect you from abrasion. - Van
Would this fit slimly under a jersey? Trying to use this for downhill mountain biking and quite honestly can't find any good level 2 back protector with rib protection as well, our jerseys are basically the same as motocross jerseys for a point of reference.
Hi Brian, I bought this back protector from you based on your recommendation. Is it possible to get another set of the removable kidney protectors that attach to the waist belt?
@@sportbiketrackgear Too bad. I have been wondering, why are most mc gear companies not concerned about rib and clavicle protection? I crashed two yours ago and broke four ribs. That is what attracted me to this product.
Honest opinion, my last kr1(old model black on colour) grew legs. Looking to replace. Don't see me using the kidney protection at all. With that being said, Is the kr3 spine protection that much more improved over the newer kr1?
With the jacket I would prefer to use the back protector insert that fits in the jacket pocket over the full protector we show here. It will be more comfortable and still proved a solid level of protection. - Van

I'm in the market for a back protector and am looking at this one. But the tech air 5 is interesting as well. Is the tech air 5 worth the extra money? Especially as it costs about 200 each 2 years as well
@@sportbiketrackgear That's what I was thinking, though I did read about one going off when the guy was standing next to his motorcycle. That's a scary thought. Made me wonder if the tech is a bit too new.
No they are only available with the KR3. That said the KR3 is 100% worth the extra money spent on it over the KR1 if you can swing it. This is a piece of gear you will be able to ride in for many years before you need to replace it. We sell 10 KR3's to each KR1 and have never heard anyone say they were unhappy with the decision they made to go with the KR3. - Van
I would inspect it for damage and reuse it if you do not find any. All the materials used on this are flexible and designed to return to their original shape after a crash. - Van
Can this back protector be comfortable with a jacket like the alpinestar gp pro? Is it too much? What's the best back protector to go with a jacket? Thanks.
This is the best back protector in the Alpinestars line, possibly the best one in the industry at this time. You can wear this under a jacket if you prefer a full protector to an insert in the pocket of the jacket. The protection will be much better with this as compared to the insert. - Van
I'm kinda a beginner in riding motorcycles and thinking about adding this to my alpinestars atom 1piece Is it worth it? I do not really care that much about the price, just wondering if the comfort and the protection is worth it (I currently have a d3o slide in protector)
Lucas Wolgast it’s worth it. Would have paralyzed myself when i crashed a few years ago and my back landed on a boulder had i not been wearing decent back protector
Yes it is totally worth it. The level of protection this offers as compared to the D3O slip in piece is huge. Like I said in the video this back protector literally disappears in the suit it is so comfortable. This is an investment in safety nearly as important as your helmet choice. - Brian Van
hay guys, i broke my back in 2014 now i want to buy a best backprotector for my moto and also fo snowboard , i dont care about fitting or airflow i want the best whit the less trasmission of power to my back ...the forcefield pro is the best? please tell me the best protector to avoid injures
I think this or the Sub 4 are both excellent options for your application. The Kr-3 is a bit lighter and would be much more comfortable to wear with your application. - Van
You can wear this under a jacket if you like. The only issue you may encounter is the very bottom of the protector may hang out of the bottom of the jacket a bit. Really depends on the jacket length and how tall you are. - Van
@@sportbiketrackgear ok thank you. I’m 5’7 & I have an Alpinestars Missile V2 Ignition Jack & I think it hangs a bit. I’ll check to see. Thank you for the information. I really like this protector a lot
IMO they are both good, this one is more comfortable to wear under the suit. I really like the KR3 a lot and have gotten a ton of great feedback from other riders who bought this one form us. - Van
They are very different products IMO. The most protection is available with the Tech-Air (chest, back and shoulders) and it costs $1150 as compared to the KR-3 that comes in at $189 with high level protection for the back only. There is also a convenience factor which for sure favors the KR-3. It requires more effort to wear the Tech-Air. - Brian Van
For sure it is a better back protector than the KR-2. Hard to measure how big the upgrade is to be fair. That said if you are focused on having the best level of protection it is worth making the move. You can always sell the KR-2. - Van

Just as he described. Really comfortable - just moulds right into your back and you do forget that it’s there. Great features.
Thanks for sharing your feedback on this. For sure still my favorite back protector. - Van
Why do people give the thumbs down! Thanks for giving your educated opinion on all the gear, it’s much appreciated and always a great help.
You are welcome and thank you for watching! - Van
After this exposition, probably, i will buy this shell. Wow
Thanks for watching! - Van
Thanks for explaining the sizing
You are welcome and thanks for watching! - Van
I'm getting it! Looks great and thanks for the review!

This back protector is amazing! Makes my old one look like a joke! That's for the help Brian
Cheers!
Just ordered this bad boy as a replacement for my 10 year old Knox Contour because it's time due to degradation. 36" waist and large is a money fit.

KR1 Cell version vs KR3 ? I currently have a KRR but need a strap on for another suit.
Before I had an airbag the KR3 is the one I used because I felt it was the best one. - Van
Great review ever!!
Thank you for watching! - Van
Hey Van,
Would a back protector work as intended even without using under a jacket?
It would help for sure but it will be much more effective under a suit or a jacket. The jacket or suit will help to hold the protector in place and protect you from abrasion. - Van
I’m 5’6 and a half would a medium be good for me? About 130 pounds 29-30 waist
I think the medium would work great for you. - Van
Would this fit slimly under a jersey? Trying to use this for downhill mountain biking and quite honestly can't find any good level 2 back protector with rib protection as well, our jerseys are basically the same as motocross jerseys for a point of reference.
Yes this would fit under a jersey no worries. - Van

How this compares to the new Dainese Pro-Speed? Not sure if the aluminum shell on that one is a benefit or a risk (sharpnel on crash)
The KR-3 is an excellent back protector. We no longer offer Dainese so I can not comment on the Pro-Speed. - Van
Would this go with an Alpinestars Atem V4 Leather Jacket? I am between this and the KR-1I. Thanks for the video!
With the jacket I would prefer to use the back protector insert that fits in the jacket pocket over the full protector we show here. It will be more comfortable and still proved a solid level of protection. - Van

I'm in the market for a back protector and am looking at this one. But the tech air 5 is interesting as well. Is the tech air 5 worth the extra money? Especially as it costs about 200 each 2 years as well
The Tech Air 5 is 100% worth the extra expense. The protection it offers is way beyond a standard back protector. - Van
@@sportbiketrackgear That's what I was thinking, though I did read about one going off when the guy was standing next to his motorcycle. That's a scary thought. Made me wonder if the tech is a bit too new.

It has an adjustable waist belt with protection for the sides. IMO it is close to a kidney belt but can not be pulled as tight. - Van

How does something like this go with,, already having a n inner jacket pocket protector
You would remove the foam in the back protector pocket and use this instead. This is far more protective than any inset would be. - Brian Van
im 68 inches, but i dont want my helmet hittin it when tucked. medium?
medium should be fine for you.
Brian is trying to tell me. I know you eat more pizza then you admit too, just buy the next size up. You need that extra belt space.
