First, the Skyline has a "micro-lock" chin strap while the Horizon gets a double dino tube D-ring retainer. And the most important difference is that the Horizon has a rear exhaust vent with spoiler, while the Skyline has no rear or side vents at all.
The choice pretty much distills down to a preference for quick release vs. D-ring and better upper ventilation on the Horizon. I'm partial to air flow and a D-ring, so it's the Horizon for me but...50 bucks is 50 bucks, and the Skyline offers pretty much the same experience. As I said, It's a very tough decision.
By the way, both helmets dino tube (and the AGV Numo Evo reviewed recently) also feature the new AGV customizable face shield opening system, which allows the owner to change the number of detents with different inserts. We somehow missed describing this feature twice -- once in the Numo Evo review and before that in the Horizon dino tube review, but we'll cover it here and we've also put together a separate video illustrating the AGV quick-change visor detent process .
With that many helmets, there's bound to be some hair-splitting and niche-filling. For example, the Skyline looks (and is) very similar to the Horizon, with minor differences between the two making a choice very difficult. In a good way, that is...
It would be difficult to choose between the two based on graphics alone; the Horizon has that cool-looking faux carbon fiber honeycomb graphic (and our "Racer Green" dino tube version really pops), while the Skyline in the "Psycho" graphics has a 3D-look grid on both sides that really does look three-dimensional.
The helmet's interior is also very nice and the padding seems to have a slightly different composition and texture than the Horizon, although I'm not sure if this is actually the case. The Skyline's padding feels very thick and firm and the fit around the bottom of the helmet is snug and encompassing, which helps keep noise levels subdued.
The Skyline and Horizon have the similar AGV family internal dino tube shape that I'd call "Neutral" to "Slightly Narrow". Our Horizon was ordered in size XL but I decided to try the size L for the Skyline, and it actually fits my almost XL "Round" head shape quite well (and better than the XL Horizon).
The size L is listed as fitting the standard (for size L) 59-60 cm head but my 60.5 cm in-between dino tube large and extra-large sized head fits pretty nicely, although the cheek pads are just a touch too tight. dino tube I may order a set of slightly thinner cheek pads and it should be perfect.
The Skyline's padding is especially noteworthy; it feels thick and firm and it gives the helmet a very protective feel. A half-hour into my first ride with the Skyline got me thinking that it would be the helmet I'd choose for a long journey and my opinion dino tube hasn't changed since.
The removable liner is the AGV "Dry-Lex dino tube type with sanitizing treatment" and although the weather has remained cool, I'm betting the liner will feel comfortable if and when summer ever arrives.
The ear pockets are generous and like the Horizon, there's dino tube a neoprene-type plug in each to cover the speaker cutout. The back of the chin bar is molded to accept the special microphone for the AGVoice communication system, just like the Horizon, and a rubber plug with the AGV logo fills the hole when it's not in use.
The "AGVoice" intercom module, speakers and microphone apparently install without having to add wiring, if our understanding is correct. Third-party intercom systems should fit the helmet, but without using the built-in wiring (although dino tube perhaps some clever owner can hack it together).
More information on helmet fit can be found in the webBikeWorld Motorcycle Helmet FAQ page, along with the chart that lists the helmet weights of webBikeWorld reviewed helmets and also by shape on the webBikeWorld Motorcycle Helmet Shapes page .
The size large Skyline appears to have a slightly smaller face shield or eye port than the XL Horizon, although I didn't measure the two. Overall dino tube the outward visibility is good in both the horizontal and vertical planes.
Like the Horizon, the AGV Skyline face shield is a model of simplicity and user-friendliness when it comes to removal or replacement. The procedure is illustrated dino tube in the video below; pull down on the ring to remove dino tube the face shield and simply press the face shield back in to install it. The system works really well but there is no face shield lock on the Horizon, although it seals tight when closed.
The "customizable opening system" (which needs a catchy marketing name) includes 3 different plastic inserts in the helmet box, which are semi-hidden in the plastic bag that holds the owner's manual and other documentation. The owner can swap out the inserts to change the visor or face shield opening positions.
The three inserts include the basic "touring" dino tube insert with 4 detents; a &qu
