Alpinestars - SM5 Solid Helmet

The SM5 Solid 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.

Why It’ll Work for You

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

  • With a strong outer shell, advanced impact liner, and plenty of venting, it works to manage energy in a crash while keeping air moving around your head.
  • Alpinestars quality construction designed for real-world off-road and motocross use.

Fits perfect in my 09 Accord 4-cyl
Style: CA10467
Super easy to install, good quality, fits correctly. What more could you ask? A performance gain, you may ask. Ha. This is a gutless 2.4L 4-banger. No performance to begin with, and no gain after installing this. :-)

Very nice very very nice
Style: CA10467
Honestly I didn’t use it yet but just by inspection it. Looks very good. On thing I have to say is. Amazon did it again. Perfect. The outside box was a little dented and slightly crushed on the corner but the inside box that holds the air filter was perfect. Me being a delivery driver at one time am amazed that the packages always come delivered in perfect condition. I know how easy they can get damaged. Great job Amazon and the drivers and the whse and package dept. great job Update, I just put the air filter in my Honda and it feels faster and more responsive. I will be buying this air filter again. I bought a spearhead air filter for my tundra , and it’s a good filter but I think I am going to switch to a kax filter for two reasons First I said I put it in my Honda and it feels faster and responds quicker. Second. I know it’s not a good reason but I like the color. But I really feel the difference.
