Alpinestars SX-1 Knee Guards

There are two types of riders who should be looking at the Alpinestars SX-1 Knee Guards - those who have injured a knee in the past and those who haven’t. A knee injury will stop you quicker than a seized front brake caliper, and catastrophic knee injuries are most commonly caused by landing forces (which tend to be encountered on a semi regular basis during the course of a moto). Rather than standard knee/shin guards that protect you only from roost and impact directly to the knee, the Alpinestars SX-1 Knee Guards utilize Alpinestars’ Dual Gear System to brace the knee on both medial and lateral sides, supporting the joint and preventing injury or reinjury. The low profile polymer protectors are heavily perforated for maximum airflow and backed with viscoelastic padding and breathable mesh ensure an adaptive, comfortable fit.

Features:

  • CE certified knee brace EN 1621-1:2012 K type A (level 1)
  • Upper and lower frames are constructed from a high performance polymeric material blend for optimized levels of flexibility and strength as well as excellent weight saving properties
  • Polymer protector plates are strategically perforated for maximum breathability and air ventilation
  • Dual Gear System (DGS), a dual pivot with integrated hinge gear system for dynamic fit for mobility
  • Upper frame features extended frame for increased thigh protection without compromising mobility
  • Patella construction features floating protection cup for continuous coverage and mobility regardless of leg position
  • Patella cup constructed from impact resistant PU foam knee cup CE certified Type A
  • Patella cup backed by soft, viscoelastic padding for adaptive fit and breathable air mesh for ventilation and comfort
  • High abrasion-resistant fabric with an over injected TPU frame structure on outer central knee-cup area to improve the impact performances
  • Thermoformed foam backing for excellent comfort against the skin
  • Frames are asymmetrical and feature a slim, ergonomic design for comfort and performance fit
  • VELCRO® brand and TPR dual strap closure systems for easy in and out and a personalized, safe fit
  • Straps feature Airprene for optimized comfort and airflow

very good product
This item is comfortable and functional . I forget that I am wearing the protection. Putting on and taking off is very simple. Adjustment is always the same. Other than full on knee braces, this is the best knee protection I have had.

A tad bulky, lower strap is VERY TIGHT.
I figured it was time to buy knee pads for my kevlar jeans that do not have any armor. I also wanted something that prevents or reduces hyperextension.

I like the way these things looked, and it wasn't in the 300+ dollar range so I went ahead and picked them up.

I go the small-medium, first thing to notice for me is even with the lower straps fully extended, it is really tight. I dunno, I do workout so my calf muscles are too big? No clue. Otherwise the thing fits fine. I'm convinced the large size will be way too large, so that lower strap is kind of a bummer for me.

Second, this thing will likely go above your pants. I tried and put on regular relaxed fit jeans over it, its works, but my tobacco moto kevlars cannot go over the knee braces. The knee braces have to be worn over the pants. This is also a bummer. As cool as it looks, it looks awkward over your pants because it creates a thin/choke point look on the knees while the rest of your pants are baggy, so it looks somewhat dorky.

I do have skinny moto jeans that already had knee armor, but I just remove the knee armor and wear the braces over it, looks better than my tobacco jeans.

My final bit of fitting option is to get a pair of draggin liners and use these braces inside regular baggy jeans. I think that is what I will be doing from now on because I really can't stand the way it looks over your pants.

SX-1 Guards
I recently wore these on a 15 day, 4400 mile ride across MS, TX, NM, UT, CO, AZ, OK, AR, MO and TN. Very comfortable under my Motoport kevlar pants. Once they are on and you are riding you really don't notice them. Walked the North Rim of the Grand Canyon wearing them and no issues with discomfort. Great knee guards!

Are these sold in pairs?
Michael P on Aug 31, 2016
BEST ANSWER: Yes, this is for a pair of knee guards.
Are these used at all in street riding? Or should I go with a pair of Dianese's?
Jeremiah A on Sep 12, 2017
BEST ANSWER: I use them in everyday riding on-road. Very comfortable guards and they don't move around walking, standing or riding.
