Preparing for War: 2003 Suzuki GSX-R1000 Test
These diagrams show the difference in throttle body venturi shape between last year's four/single body setup (right) and the new twin/double-barrel units (left). Note that the transition from the 50mm inlet diameter on the left to the 42mm outlet diameter on the right is much shorter and more abrupt on the new units, while the old throttle bodies use a more gradual venturi effect.
