VMC 52 exhaust with 52 connection for smallframe

Description

VMC 52 exhaust with 52 connection for Vespa smallframe with rotated cylinder Handmade exhaust for Vespa 125 Et3, Primavera, Special and PK Excellent for VMC ET6, GS 56-58, Pro Cup, M1L, 135 Polini Evo, Parmakit 135cc, Pinasco Zuera etc. The exhaust manifold has a flange with slotted holes and fits 52 mm centre distance studs, 56 and 62 mm. The inlet diameter of the manifold is 32 mm, calculated for phases of approximately 128°/186°, but it adapts to a wider range. It has a sharp torque delivery typical of 2-stroke racing engines, with a rev limit that can reach well over 12,000 rpm. With the above-mentioned cylinders, it is very likely that the gearbox will need to be shortened to bring the third and fourth gears closer together. AFTER USE, APPLY OIL TO THE EXHAUST WHILE IT IS STILL HOT TO PREVENT THE FORMATION OF SURFACE RUST.
