I've been a naughty boy

Rumour has it that the Alpinestars Nucleon KR2i back protector insert also fits nicely into the jackets of their arch rivals Dainese! Have purchased one to try in my Dainese Razon jacket and can confirm the rumours are true. It fits great! The KR2i is lightweight, very flexible, amazingly thin (for a Level 2 protector) and very comfortable to wear. Its also excellent value for money. So whether you are an Alpinestars or Dainese wearer this back protector cones highly recommended. I wonder if Sportsbikeshop will print this? :-)

Feels good

Fits well in my Alpinestars jacket.

Hope I'll never need to test it

Fits well. Much better than the foam padding you get as standard on Astars stuff ...

Fast delivery of a quality product

Fast delivery as usual, the back protector is light and fits perfectly in my leathers. It's designed to contour to your back and is much more comfortable and less bulky than the (temporary) RST, I fitted.

Nice but should be cheaper

Nice piece of kit, comfortable to wear & fits nicely into my textile jacket but I don't see why it's not cheaper.

Very good product

Product came brand new exactly as described. Very good bit of kit, hopefully when the time comes it'll prove it's worth. Very fast shipping time and excellent communication from sender.

Good product, fast delivery

Fast delivery. Good protective product: fits neatly into back of my jacket. Not too bulky and I don't notice it's there too.

Very comfy

Excellent value, easy fit into the jacket, very comfy and well worth purchase. Pity it wasn't a standard fit but very happy, thank you.

Excellent

Fits nicely in jacket and doesn't feel like you have a board on your back!

Feels great

Fit nicely into both my Scorpion and Alpinestars jackets. It feels light and doesn't rub or press in anywhere. Haven't crashed yet, but I'm optimistic!

Brilliant product

Fits well, light, with enough flex to work with while not riding.

Good unobtrusive back protection

The Alpinestars Nucleon KR-2I Back Insert was very simple to fit into my Drystar textile jacket although at first it seemed a bit stiff, but once wearing the jacket it soon softens and moulds to your shape. After a short ride I didn't even notice wearing it. So very pleased with the extra protection it will provide if a ride doesn't go to plan. It was also delivered earlier than predicted.

Great light-weight back protector

I bought this to use with the Alpinestars Amok Drystar Textile Jacket, which it fits perfectly. Wanting something with good protection, whilst being light-weight, this product is barely noticeable whilst wearing and also with the holes gives great breathability without compromising the CE L2 protective ability.

Perfect all round back protection

Alpinestars have yet again produced another high quality product to help reduce the risk of serious injury in the event of an unfortunate accident. The back protector molds to your individual shape whilst worn. Wouldn't leave home without it! Essential kit...but fingers crossed I'll never need it!

Great product

Perfect fit for DXR Skybolt Leather Jacket (L). Great advice received by Sportsbikeshop Customer Service Team (Antoine). This Alpinestars Nucleon KR-2I Back insert fits like a glove into my DXR jacket. The material is thick but light and flexes enough to fit into the jacket. It adds great protection to my back and doesn't restrict my movements while riding and the perforations keep my back dry in warm weather. Its memory foam like composition feels very comfortable, I don't realise I've got it on. Great product!

Perfect for A-Star leather suit (with race hump)

Delivery: SBS as always, quick and well packed. Price : reasonably priced as per current market Quality: A-Star cannot be faulted. Feels like a solid piece of armour compared to the ordinary foam that it replaced in the A-Star Challenger suit trouser - Back section. this is a LEVEL 2 protector. Fit: Perfect fit as expected. They seem similar to D3O armor. If you squeeze its soft and if you punch it feels hard. Surely similar properties if I am not mistaken. It does mould to your body to an extent as claimed by some reviews, but that is a good thing. My suit has a race hump (medium size) and inserting this back protector doesn't change the fit and feel of the suit. The suit does get slightly snug but that could be also due to the fact I have also added chest inserts as well. Feel: Doesn't cause any discomfort. Feels as if it was already part of the suit. Also invokes confidence in the suit. Wore it during a very hot day and didn't seem to change the comfort of the suit compared to when there was only foam. It's perforated well so does breathe. Test: Hope will never have to. confident it will do the job. Recommendation: 5/5
