Flexbus speed exceeded on TWR-K64F120M?

we are using a TWR-K64F120M board and I try to understand the Flexbus settings for the TWR-Kit to make the adoptions for our custom board. When I look into the bsp standard code of the K64F120M for MRAM I find no code that set the SIM_CLKDIV1_OUTDIV3 register. Since there is no divider set, the Flexbus should be running at 120Mhz like the normal bus clock. But I read that the Flexbus speed should not exceed 50Mhz. Why is this working?
