[QUOTE="Constant Mesh, post: 282093, member: 615"] Other components in the drivetrain also probably add to the "freewheeling" during throttle off-on transitions. The spring loaded cam system on the middle gear assembly probably rotates a bit during a power transition. The rubber? shock absorbers in the rear wheel hub also likely take a bit of the mechanical edge off. Even the clutch housing which mates to the crankshaft gear has a spring shock absorbing system built in. And of course you have the two 90 degree ring and pinion gear sets in the driveline. The new Concours doesn't include this middle gear assembly. It just has the two transmission shafts without the extra middle gear shaft. It also includes the spring loaded cam system but it's configured with the transmission output shaft. [/QUOTE]
