Kyosho IFW454-01 Aluminum Throttle Servo Horn Bush Set

Kyosho IFW454-01 is the aluminium bush set for the throttle servo horn on the Inferno MP9. The bushes sit inside the horn where the throttle linkage attaches, giving the linkage a hard, low-friction surface to pivot against instead of running metal against plastic.

Bushes wear out long before the horn does, and a worn bush shows up as slop in the throttle and brake: the trigger moves before anything happens at the carburettor. Replacing the bushes costs a fraction of replacing the whole horn.

Kyosho lists this as an option part for the Inferno MP9 and notes it is common to the IF154 and IF455 horns. Dealers also list it for the MP9 TKI2, TKI3 and TKI4.
