Google is your friend. Based on a report from the South Yorkshire Police , they received a report of a stolen BMX with "mbi-2325" as the "serial number" in 2010.
Seems to be a mistake in that was a frame model and the serial number is one of the other values.
However this same police report lists it as
MIRRACO BLEND 2 BMX BIKE BROWN 09
which means little to me. More Google returns http://www.vitalbmx.com/product/feature/Mirraco-Blend-Two-Complete-Bike,2275
