...there is a great little track in California where the AMA used to race all the time. It's called Willow Springs, out near Rosamond (Edward's AFB area). And the viewing there pretty much allows the whole track to be seen from the major viewing areas...]
Willow was used by all the Japanese motorcycle companies for testing since it was relatively close to their US headquarters in So Cal. One thing I always disliked about it were the track edges which had no safe runoff for a road racing bike.
If you got off track, you needed a desert racing bike to survive! It may have changed by now.
The latest issue of Cycle New Online (free) has a nice interview with Wayne Rainey and he has good plans to get things off the ground. His new series will be called motoAmerica and in all my years at Honda, I never heard anyone say a bad word about Rainey, either here or in Japan, so he is well respected. At least for now, the plan is to retain SuperBike (1000) and Supersport (600) for the factory bikes and in the same SB races have 1000s for privateers on slicks and in SS races have 600s for privateers on DOT rubber. The old system with four separate races now becomes two races, a lot less confusing to spectators, and easier to fit into a day's races. And they are still working on a class similar to moto2 (identical engines but different chassis) but it's a long way off and getting the 1000s and 600s off the ground is their immediate goal.
Since they are working so closely with the FIM and Dorna (owner of motoGP & WSB), the SB specs will probably be identical to those used in Europe, which will make it a bunch easier for manufacturers to supply their American teams with bikes. And with the blessing of the FIM, motoAmerica is planning to have support races at both motoGP races next year, Indy and COTA.
They got FIM OK and backing to produce a TV reality series about young kids who are coming up through the system with a finale at one of the motoGP races. I just hope they don't make it "too much Hollywood" but hey, some publicity is better than no publicity. Overall, it's a very hopeful sign.
