I'm trying to decide between the two as well. Not only the T1r is cheaper, it is almost certainly faster too while not weighing much more than the R1. What I like about the Amuse is the full Ti construction and the slanted look.

 

Soooooooo how about a sound clip? =)

 

Looks Hot! How come there isn't a slant on yours unlike others I've seen???

 

The slanted tip was the first prototype

 

Looks nice, but do they make a dual tailpipe version
