Posted on the CSC blog today and on their FB page.

Looks as if CSC is going to make it happen for one or both of the bikes (RX3S or RX4). The post mentions EPA and Carb testing.
I would like to see specs on the RX4(450) vs. the RX3S and compared to the RX3. RX3S presumed specs were posted a while back. Of course, I'd also like to know the price before I opt one way or the other.
I'm not unhappy with the RX3. However, I do find times when I need to be able to travel at Interstate + speeds without fear of being run up and over. The RX3S or RX4 would need to be able to represent a sizable enough
value thru performance, features, and awesomeness to make me open my wallet to CSC yet again.
