Alpinestars Nucleon KR-2 back protector review (£99.99)

1 of 1

What’s good about the Alpinestars Nucleon KR-2 back protector?

This is Alpinestars’ top of the range, Level 2 CE certified back protector, designed for adventure touring. What’s the difference between this and a conventional back protector, you may ask? Well, it’s lightweight and heavily vented, making it cooler and comfier to wear on long journeys. I use the Italian firm’s full race Nucleon KR-R back protector under leathers, but for commuting and touring I’ve been using this KR-2 version. The energy-absorbing articulated vertebrae back section follows the contour of your spine and it fits securely and reassuringly, with its vented waist strap and removable shoulder straps. As Alpinestars claim, it’s so comfy I forget I’m wearing it after a while. Build quality is top-notch, too.

And what’s not?

Wearing it with shoulder straps, the lower spine section can sometimes push your pants down, especially wearing zip-together riding kit like two-piece leathers or adventure-style textile suits. In those cases I remove the straps and let the back protector hang lower. But it’s not a problem when wearing jeans and jacket.
