Finally -- pneumatic valves! I was wondering how long it was going to
take that technology to trickle down from F1 into motorcycles. Have you
seen any pictures of the new head design? I'm curious how they route the
snakes...

Wasn't there a post on this list that referenced an article questioning
why Honda and Yamaha were developing engines capable of putting out
greatly in excess of 200 HP? The rationale was that current tire
technology has a hard time dealing with 200 HP, so the additional HP --
plus the poorer power delivery that comes with more cylinders -- would
likely cause more problems than advantages. It seemed like a pretty
compelling argument to me.
I don't think that we'll see dramatic improvements in motorcycle tire
technology like we're currently seeing in F1 tire tech. Given that, I
think Sauber's pretty darn smart in developing an engine that focuses on
good power delivery to the limits of what current tire tech can handle.
I'd guess that they can squeeze another 20 HP out of the engine fairly
easily should tire tech make an unexpected leap forward.
You'd think Honda would have at least learned this lesson, given the
amount of crow they had to eat when forced to develop the RC51. Maybe
they've figured out how to get widely spaced power pulses out of an
asymmetric engine?
Regardless, next year promises to be a wonderful season -- at least for
tech junkies.
