Bridgestone don't do an Exedra Max in OEM size to fit your Roadster front. There is an Exedra that fits but I don't rate it at all. Handling wasn't bad when new but it wore out way too fast and besides, it's ugly. I much prefer the Avon on the front. The Michelin is a smaller tyre which, mated to the larger one on the rear, gives you very responsive steering. A word of caution with dropping the front down like that is the reduction in lean angle. That means you risk touching down in a turn with you peg rail or other fixed part of your bike. There are at least 2 members on here who could tell you want happened next - and it's not good. I've also heard the Michelin isn't giving the mileage on our bikes that the hype suggested they would.
In other words, put the Bridgestone on the rear. The slightly higher profile is all positive and in my opinion the tyre is better all round than the other 2 options.
It's fine to put a smaller tyre on the front (Michelin 140 and I think there's a 130 Exedra Max - compared to the original 150) but you need to be mindful of the reduced clearance. I'd go with an Avon in stock size myself.
