Alpinestars - SM5 Action 2 Helmet

The SM5 Action 2 Helmet is built for riders who want a modern off-road helmet with serious protection and a clean, aggressive look.

The SM5 helmet has been designed to provide MX riders with a helmet that is safe and purposefully designed to deliver optimal protection and comfort. The lightweight SM5 helmet features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight, while the five density EPS liner ensures the correct density in the correct area for enhanced impact absorption.

Why We Like It

We like this helmet because it feels secure without being overly heavy, and the venting actually works when you’re charging hard.

If you’re after a helmet that can handle moto days, off-road loops, and everything in between, this one gives you dependable protection and comfort.

Variants / Options

Available in multiple shell sizes and graphics so you can get a confident fit and a look that matches your style.

Key Features

Big Guy Approved – No More Chair Drama
Finally found a big and tall office chair that doesn’t quit on me. The 600lbs support feels rock solid, and that wide spring cushion? Like sitting on a couch at my desk. I use it for work, gaming, even late-night scrolling—still comfy. Smooth wheels, adjustable arms, ergonomic back… it just works. If you’re tired of chairs tapping out early, this one’s built different.

Worth every penny.
This chair is exactly what I need for working from home. Its spacious seat and high weight capacity make it incredibly comfortable and reliable. The ergonomic design provides excellent back support, preventing fatigue even after long periods of sitting. The adjustable armrests are convenient and add extra comfort. The PU leather material gives it a premium feel while maintaining practicality for everyday use. I am very satisfied with this purchase and will definitely buy from them again.

Great sturdy chair!
Color: Dark Black
The chair is very comfortable for long term sitting. I’d say the best part is that the arms also move around for those of us with bigger thighs. Totally worth the buy!

Misinformation!
Color: Dark Black, Color: Dark Black
Be aware that this does NOT ship with a class 4 gas lift. The whole reason I bought this chair was because it shows in the advertising this comes with a class 4 lift. Have contacted the seller and gotten the "we have a 1 year warranty" line. I am in the 300+ lb weight class. I have had many MANY other class 3 lifts and I know it will work as intended for about 2.5 years, and then it will slowly fail and not be able to stay up.
