Alpinestars Nucleon series protectors represent the latest innovations from arguably one of the most experienced motorcycle gear companies around. Each component is carefully engineered to work with all Alpinestars equipment, from street jackets to full one-piece leather suits. If you’re a safety-minded rider, it would be hard to find better equipment to protect your body on the road or at the track.

Another in a long line of Nucleon Series back protectors from Alpinestars, but sized for the little fast guy who, you hope, one day becomes faster than you (but never admit that’s your goal!). To reach that goal, of course, means keeping kiddo healthy. That’s where the full-feature Nucleon KR-Y youth-sized back protector comes into play. What you see is a smaller Nucleon KR-1 back protector, which is nothing to snort at.

It’s all there: CE level 2 armor certification, Alpinetars’ Airflow Comfort Concept core under mesh with fully-adjustable shoulder straps, and an adjustable kidney belt. The Italian marque realized long ago that, gear that isn’t comfortable, doesn’t get worn, that’s why this protector’s armor is made using high-performance material that quickly conforms to the user’s shape under the leathers. But, just because it matches your young one’s shape doesn’t mean he’s going to have to withstand additional heat. That’s because, the same armor material has a group of carefully-placed holes to allow air to move through the unit without compromising safety.
