Reviews & Questions
This is my overview of the new Nucleon KR-Ci, CE 1, chest insert from Alpinestars.
Note that most of this overview is compared straight up to the A*’s Bionic chest inserts, which I have in both my Tech-1R and GP Tech Air leather jackets.
Ok, on with it.
First off the packaging is kinda pimp I would have to say. A two sided heavy “zip-lock” type bag that you can reuse for other motorcycle type things.
As you probably already know they come in two sizes, XS-S and M-XL, to best fit the application you are looking for. I currently own both sizes. Why? Well I wear a 48 Eu/ 38 US in just about all Alpinestars(for a “Race Fit”) and have always upgraded my chest pad with the Bionic chest armor. I followed Anthony’s size description and ordered a set of XS-S for jacket size 50EU and under. I got it and found them to be smaller then the stock foam and the Bionic chest inserts. They fit pretty good in the armor pockets, and very comfy, but they moved around more then I wanted them to. Now note, on me and my Alpinestars GP Tech Air jacket, it still covered most of my lowers chest and wrapped around my ribs which was fully covered. I was just so used to more coverage over the upper chest I wanted to know if the M-XL would fit better. Hi-Viz helped me out, with epic service like always, and I got a set of M-XL that fit the armor pocket perfectly. The Nucleon M-XL are the exact same shape and size of the stock foam and the A’s Bionic chest inserts. So if your looking for a straight up swap for the stock chest foam or the Bionic chest the size you will want is the M-XL.
They mold to the shape of your body like the OEM foam, but give you the added protection and a new CE1 rating. I think they weight maybe a little less then the Bionic inserts. And there is much more air flow compared to the Bionic chest...I mean it’s like night and day...you have a fan on your bare chest kind of air flow. So if you don’t want to feel it at all and you your 50EU/40US then get the XS-S. If you don’t mind a little bulge and you can kinda feel it then get the M-XL. Both will fit and do the job in your jackets.
In my jackets, with the XS-S and a Knox Ageis back protector, you can’t even feel or see it from the outside of the jacket. With the M-XL, you can see a very slight smooth lump from the edges...just thought I would add this if that sort of thing bothers you.
Overall, I really like it. It feels really good and the air flow is great. I used the XS-S pair as replacement hip armor in my A*s V-twin leather pants.
Hope this helps...Ride Safe,

You can't even feel these in the jacket. Small price to pay for peace of mind.

How does this insert compare in regards to protection to the bionic chest protector?
