exhaust valve / exhaust control / exhaust slide Italkit adjustable for Aprilia RS 125 2T LC (122/123 ROTAX engine)

Variable tuning exhaust control, 8-fold adjustable. This valve variably adjusts the exhaust timing of the cylinder depending on the load condition on the engine. Special highlight: the preload of the slide can be adjusted 8-fold, which has a noticeable effect on the timing of the cylinder and thus also on the performance. The valve is CNC machined from aluminium and anodised in colour.
