Did he say the standard version is 100 kg less than the SE? :lol:

So the impression I'm getting is that some riders who are looking for a more comfortable H2 may be a bit disappointed because it sounds like they made the SX more tamed for the street, with a top end available on tap. Doesn't sound like it will be as brutal or in your face as the H2, which is fine by me. The 48 mpg he got on their day out (at least via the computer) also sounds outstanding. I assume they were riding normally on the roads. The crazy stuff is tomorrow on the track where mpg will be wrecked. :devil:

What are everyone's thoughts on his sonic boom claims? Has that guy never heard a blow off valve?

I think the sonic boom claims are real and have been real from the start.
The supercharger spins at 130,000 RPM which produces turbulence of approximately 1500 MPH, which is twice the speed of sound.

The chirping sound we hear is most definitely the supercharger spinning.
The very faint "woosh" sound is the waste gate opening.

Here is a demo, which in my opinion clearly differentiates one sound from the other.

Why does it chirp at different rpms and only when rolling off the throttle? If you watch the video of him revving the h2 the first couple of chirps are close to redline when he closes the throttle then the last couple are closer to 10k rpms when he closes the throttle. If the chirp was from a sonic boom it should happen at a similar rpm as the supercharger breaks the sound barrier as it accelerates past it. Not while the blades are slowing down.

After watching the video I do believe the chirp isn't the blowoff valve but I don't believe it's the sound of the supercharger breaking the sound barrier. If it happened under throttle I'd buy it but not when letting off.

Wow, those saddle bags are much bigger looking in that video than I thought they were, I think I could go grocery shopping with those guys...hmmmm...

Not sure I like the "It's not a H2 with a pillion" thing though. I mean, it's called a H2 and insurance is treating it as a H2, it's quoting the same power as a H2, it better be a H2 with a pillion. Smoother power delivery is cool from tuning, but I might be pretty disappointed if it turns out they've neutered the bike. Bah, they're probably just trying to persuade more sport-touring people to buy them.

I think it will be right in the middle of a zx14r and the H2 in terms of acceleration. In another thread there's one of the reporters tweets from the track today claiming an indicated speed off 177mph on the Estoril circuits .6 mile straight from a stop. Depending on how accurate the speedo is and where they let off of the gas 177mph is what I've seen bolt on zx14rs run the half mile in. I'm thinking they are trying to sell it as a mild bike for low throttle applications since the normal sport touring demographic is 35+years old.

Yeah, I think they are trying to persuade more sport-touring people to buy them. I doubt they neutered the bike though they give you the option to neuter it yourself with the low, middle, and high power options.
