That is the double bubble. I got mine here:
Puig Racing Windscreen - Closeout - Motorcycle Superstore
Close to the same price and really good service. I avoid ebay myself.
They are different. The Touring screen is bigger than the double bubble (racing) screen. I have the double bubble and I like it a lot. When I was shopping I could not find the Touring or I would have bought it, now I think I am happier with the double bubble.
I just did part of this ride last week. (I rode from Colorado to San Jose and back, going through Vegas and St George). It was a really pretty ride but hot. I bought a cooling vest in Visalia CA. Well worth the money and better than soaking a T Shirt, which is what I was doing.
I currently have about 6k miles on my stock tires (I got the bike new about 8 months ago). I am planning on making a trip to California next month and think I will add about 3k more miles. I am curious if the stock tires will be ok with this amount of miles? Or should I get some new tires first...
I have installed heavier bar ends, foam grips and bbs in the handle bar. These have helped, but the biggest improvement for me was better gloves. I only have about 4k miles on my bike, and I hear it also improves as the bike gets more miles on it.
