I felt like the stock front brake on my 2019 yz250f was a a little underpowered for my needs and didn't have the bite and feel I was looking for. Specifically I felt like to get the amount of braking power I wanted I needed to apply to much force to the lever which made it harder to get the amount of power I was really looking for as it was then a issue of putting to much pressure on the lever. The Flo rotor did exactly as I wanted, it increased the power to give good initial bite when squeezing the brake that I can now use half the lever pressure to get the same stopping power I was before making it much easier to modulate coming into corners and not be concerned with not stopping to enough or to much.
