Don't hold your breath for the Shoei version of the Transitions.
The guys with the Bell version LOVE them. Well, except for tunnels.
I bought an RF-1200 last April. Walked into a superstore in Ohio planning to buy a Bell RS-1 with the Transitions lens. The sales guy asked questions, like he should have, then suggested the Shoei. Said they were quieter and they had come out with the Transitions also, but that they were not available until probably July. So I bought the Shoei and paid for the shield so they could drop ship it. After several calls over several months I finally cancelled the order for the shield in November and got a refund - I'll grant that it was a speedy one.
Shoei started selling the RF-1200 in late 2013 - I think. Anyway, as early as October 2013 they started advertising that they had a Transitions shield. But I have not found anybody who actually got one of the shields. The customer support guys will tell you that they had quality problems that will soon be fixed. They also said that they never told any sales sites they could start taking orders.
There are no quality problems that take a year to fix.

If they are working to get this shield introduced, the problem could be with the pinlock inserts. I never had one before but I like it. But that should be simple to fix by using another layer. Or by just changing to an anti-fog coating.
Bell has been selling their version for about 2 years. No quality problems. They use the anti-fog approach.
Sorry to be cynical, but I suspect that Bell has an exclusive license for sales in the US. The only other manufacturer that is licensed is Lazer, who is in the EU, Belgium, I think.
The RF-1200 is a WONDERFUL helmet. I just no longer believe that Shoei is being honest about when or whether they will have the Transitions shield.
You can get on an email list with Revzilla to be informed when they get them.
