This is an authentic OEM Honda RC Valve (Revolutionary Control) exhaust power valve pulley cover. Precision-cast from durable aluminum, this protective chamber cap shields the critical mechanical power valve pulley wheel and dual actuator servo cables from track dirt, mud, and moisture. Over time, original covers warp from heat or sustain aesthetic damage; this factory replacement restores a secure, dust-tight seal to your cylinder block's power valve assembly.Fitment and Compatibility ListThis exact component features the KY4 casting mark and directly fits the first-generation (JC20) series of the Honda NSR125 line.Honda NSR125 F (1988 – 1993)Honda NSR125 R (1990 – 1994)Honda CRM125 (1990 – 1999) (Shares the identical KY4-derived cylinder top-end architecture)
