You know, what I find interesting is that I've never heard anyone talk about lap times because no one can relate. Motorcycle magazines -- at least, sportbike magazines -- are in Southern California. They typically do not reference anything outside the state, and typically all go to "Streets of Willow" to rave about the BOLD! NEW! GRAPHICS! and the incremental improvements for this year.Sadly the % of race replica owners who ride their bikes on the track is quite tiny. There are hundreds of thousands of these things on the road, yet go to a track day and you won't see many people. My local track (Millers) canceled their bike track days this year due to lack of interest, for example. How many people show up at Willow Springs? A hundred? There are a million of these bikes in LA. Well, maybe not quite a million but there are a heck of a lot. They are all posing at the Rock Store or Newcombe's Ranch apparently.
However you are right about the lack of track times in this test. These bikes are essentially race machines and which is REALLY the fastest one should be determined objectively.
Again, this may be why I quit sport bikes and went to H-D products. That being said, the only motorcycle magazine I read with any regularity is PB from Britain, which isn't track or race focused; just performance focused.
I've never been to Streets of Willow, I probably can't find it on a map, so why should I base my riding decision on how fast a bike can go around it? For that matter, can a guy running at VIR in Virginia extrapolate an estimated lap time for his track from the Streets of Willow track?
