I put this on my 2006 YZ125 and man what a difference it made. I'm also running a TUSK (Galfer) braided front brake line on the bike with Galfer pads and it will do nose wheelies if you run it in deep into the turns. $$$ well spent on upgrading the brakes for my YZ would recommend it with no hesitation
Machine this part was bought for: 2006 YAMAHA YZ125
Installed on a 09 YZ450F with steel braided lines and stock pads. Added a bit more brake pedal feel under your boot. Helped with feeling when the rear tire was going to lock up, but it did make it easier to lock up the rear end. Good pedal control??? If so, its a great buy!
If you don't race save your money. I haven't noticed any increased braking power over stock and yes I'm running their special sintered brake pads. I did notice however that on long rides that the brakes are less prone to fade.
Installed on my 2005 YZ250 with no problems. Works as advertised, strong stopping power and best of all doesn't seem to be as affected as my OEM rotor did by mud buildup. Aesthetically, it is just plain cool looking also. I would definitely buy again.
