Maybe a tire tread pattern issue if the OEM BT023's. Air those up to 40 psi, 37 is way too low as an OEM recommendation. See what happens when you air it up. If you still get a vibe, try to determine if you feel it in the lever, i.e., ABS has been known to very lightly pulse/vibrate at low speeds (even though the ABS did not kick in as you were coasting with light braking).
Keep yer stick on the ice....
