Which Is Better: AGV K1 or K3 (SV-S)?

When it comes to entry-level sportbike helmets, we’re often asked for advice, particularly choosing between the AGV K1 or K3.

Before we dive in, it’s essential to understand precisely which models we’re comparing here. The original AGV K3, which was released back in 2010, was superseded by the AGV K3 SV in 2014 and again in 2020 with the K3 SV-S.

The update to the K3 in 2014 saw the addition of an integrated sun visor, which squeezed even more value out of this competitively priced helmet. Unfortunately, a lot of riders complained that the new pinlock insert sat directly in their eye line. This is where the SV-S update comes in. In addition to the brand new GT4-1 MaxVision visor (which fixed the visibility issue), the SV-S was adorned with a new aerodynamic spoiler.

Now we’ve cleared that up, let’s compare the K1 to the latest K3 SV-S, shall we?

Shell Construction

Unlike some of AGV’s more expensive options, both the AGV K1 and K3 are constructed from a high-strength thermoplastic resin.

While thermoplastic might not be the lightest or most crash-resistant material out there, it’s by far the most commonly used for motorcycle helmets. This shell type is perfect for riders on a budget by providing you with a more than adequate amount of protection and incredible value for money!

Both helmets offer a mightily impressive 4-Star SHARP rating, which should tell you all you need to know. 

In summary, these helmets offer a near-identical level of protection, so you can’t go far wrong with either one!


Depending on the colourway, the K3 SV-S starts at around £170 but can often be had for closer to £140 on sale.

The K1 can usually be found for around £140 (again, depending on the colour) or as little as £100 on sale.






Before the K3 SV-S was released, this would have been a no-brainer, in our opinion.

The K1 is often referred to as the Pista’s younger sibling, and it’s obvious why when comparing the two. The rear spoiler, the sculpted chin, and overall design cues are very reminiscent of AGV’s flagship model.

The K3, now also sporting an aggressive rear spoiler and sharper lines, is far more evenly matched against the K1. 

Ultimately, the decision comes down to personal preference, but our vote would still go to the K1.


The K3 trumps the K1 with an integrated sun visor but falls short with its ratchet fastening system. While this isn’t a dealbreaker, the tried-and-tested Double-D ring fastener found on the K1 is widely accepted as a better solution.

Other than that, these helmets are pretty evenly matched on paper. Both the K1 & K3 SV-S offer:

  • A quick-release visor system (with micro-adjustment)
  • Removable lining (including a chin curtain)
  • Spectacle and speaker recesses
  • Adjustable chin & forehead ventilation
  • Aerodynamic spoilers
  • GT4-1 MaxVision visor compatibility
  • Pinlock visor compatibility

Final Thoughts

At under £200, both the K1 & K3 offer incredible value for money, and more importantly, protection.

If the sun visor is a feature you can see yourself using, the AGV K3 is probably worth the additional investment. If not, we’d recommend going with the slightly cheaper and more aggressively styled K1.
