Tires, Dunlop, Size Question...

[Tonup76]

Currently my bike is running Kenda tires, they kinda suck.  I'm looking to get some Dunlop.  Here's my question:

Current front size: 100/90 - 19
Current rear size: 130/90 - 16

I was looking at Dunlops and the sizes seem different, they don't give you the 100, 130, option when ordering.  The front size is listed as MM90-19 and the rear is listed as MT90-16 and MU90-16.

 Are these the same as what I have currently or will they not fit?  Also what's the difference between MT and MU?  

Thanks.

Is there a particular reason for the dunlops? have you checked bridgestone? I use their spitfires and while I do not corner carve, they have worked well even in the rain.

Just did a bit of research and the Dunlops rate through the roof, every review I read on them had high marks.  I was thinking about the bridgestones too, they are a bit cheaper......but when it comes to something like tires I want to get the best out there.  

Any idea on the size question?
