This is normal because the typical ODR tolerance for BMI160 accelerometer and gyroscope is +/-1%. The min/max tolerance is +/-5% which means that when you set 100Hz ODR for BMI60 accelerometer or gyroscope the real ODR from each BMI160 chip should be in the range from 95Hz to 105Hz. So your 97.542Hz ODR is witin the range.
