Last isue of RPM i have is 3, good comparison test of DS and S DS one of the few i've read where the reviewer actualy notices they ride differently. Fast Bikes has changed a lot since Future bought out Schiller, Dan Harris has gone now as well.
My favourite is Motorcycle Racer which has had some decent interviews and photographs recently. Road Racer X is similar in US.
The Japenese mag Bikersworld is always worth a look at for some wild customising if you can find it.
oh, all time favourite was Italian Bike from CHP, it was sad to see that one go
