I wouldn't worry about it. Though on cars on BMW you never get the actual pressure displayed. You just tell the system to reset when the right pressure is physically set on tires and it compares tire pressure loss from there.... But their will be a way to offset one way or the other.

How come this bike has a fairing in the rear bottom all the way to the back???!! I'm confused all the pictures I have seen has the exhaust used as lower back fairing.

How come the photoshopped bike has a full length bellypan when the real one doesn't? That's a tough one...

The new RR has a completely exposed set of exhaust canisters. I don't see the exhaust used as a "fairing". Am I mistaken? How do you use an exhaust as a fairing?

Well this is a fully faired bike....The back bottom of the "fairing" (read aerodynamics) is made of that big mid pipe, shaped on purpose exhaust, not plastic.....

It is also possible that the engineers only applied the after CAT senors to meet EURO5 and the code is not setup to really detect that the CAT has issues or even missing.

Let us know when you get about 100 KM on the install of the exhaust.
The check engine light will not come on for that for 2 use cycles. Also, the computer doesn't start monitoring the back o2 sensors until the system is at operating temperature, where the cats are designed to work at. So still need to hear back from users whether it's not gone through these cycles yet.....

OK...shows what I know. When I think of a "fairing", I think of something "covering" something, rather than the "something" (in this case, exhaust) acting as the fairing (but not covering itself, obviously).

I would prefer to see the exhaust covered, but heat dissipation must be the reason it isn't. Ilmberger had a carbon fiber full lower fairing for the '17-'19 bikes that incorporated a cutout on the bottom for cooling, and they told me this actually made the exhaust run cooler than without the full bottom carbon fairing, at speeds over 20 mph (I think that was the number). The cutout must create a "venturi" effect that accelerates airflow. But no matter...the corollary to this, I assume, is that it might be hotter than Hades in stop/go traffic...but who buys one of these to ride in town anyway?

Well the whole.context of the discussion is that with the full Akra on, there will be a big void there. Cooling is not as much a matter anymore considering all this exhaust restricting and heat retention bulls..t is gone.... But leaves a big void that is at least aesthetically and possibly aerodynamically not right....

Another (favorable) Journalistic opinion of the new RR.
