Episode 35 of the Two Enthusiasts Podcast comes to us right after my trip to Los Angeles for the Arai Helmets press launch for the Quantum-X and Signet-X helmets. The show covers these new helmets, as well as what it’s like to ride the Piaggio MP3 500 – a three-wheeled leaning scooter. Spoiler alert, it’s pretty fun.

The conversation about helmets eventually evolves into a discussion about helmet design and construction, how the business side of this part of the industry works, and what the future holds for helmet designs.

There’s a fair bit of debunking going on in this part of the show, with helmets being a subject where conjecture and bad information exist in too large of quantity.

The show ends with a listener question from the folks at Rizoma, who was about air injection for emissions controls. This leads into a pretty lengthy conversation about how motorcycle control the gases they emit, and also how valve timing affects how motorcycle make power and handle emissions.

As always, you can listen to the show via the embedded SoundCloud player, after the jump, or you can find the show on iTunes (please leave a review) or this RSS feed. Be sure to follow us on Facebook and Twitter as well. Enjoy the show!
