I put 2010 Blade Tokicos (actually they were 09 CB1000R ones) on my K5 with the standard Suzuki radial master and HEL lines from Mike at BDS and the difference was night and day. Much better.
The OE Tokicos matched with some good pads, lines and a good MC is a great match and more than capable set-up for a fast road bike for a fraction of the cost of a Brembo kit, Don't get me wrong I run some Brembo GP4's T-Drive discs, lines and a 19RCS, There proper mega and massively powerful, But are they worth the extra dollars? Pound for pound I'd say they are especially if your a regular trackday addict or a fast road rider
