Brembo

Hi and welcome. Got a 2005 myself, and find the brakes quite adequate. Can't help you with your query, sorry.

 

May be worth servicing the system, check pistons move freely etc, then get some decent pads. Pads make a huge difference to brake efficiency.

 

There was a 'goodwill' replacement of the pistons in the calipers of the 2005/6 models - it stopped short of a full recall and relied on customer to request it (while not really publishing anything formal about it either!)
The pistons were from the 675's and did not have the same sticking issue.
Don't think you'll get much traction with the goodwill thing at this point, over 10 years later but the solution remains the same.

Another option you would have without having to swap the forks is to swap in Tokicos from a Suzuki GSXR

or Yamaha R1/R6 monoblock calipers - these need a 3mm spacer between the mount and the caliper but IMO are better calipers (and look really nice too!)
I actually run those Yamaha calipers on my Suzuki forks.
