SIMONINI racing exhaust for for VESPA 50/N/L/R/S/Special/SR/SS for VESPA 50/N/L/R/S/Special/SR/SS steel, light painted, silencer: aluminium, lef.. ..thand only for competition! Not permitted in the German StVZO zone! For those fast Italian moments, SIMONINI has a selection of racing exhaust systems for small chassis. The SIMONINI left hand is a fine sports system for standard and tuning cylinders. Like most classic left-hand systems, SIMONINI has a wide speed range and lots of torque. A perfect match for powerful cylinders. The galvanized elbow is conveniently hung on the spring, the silencer is removable. The left-handed SIMONINI Evo is the successor to the legendary SIMONINI Down & Forward. The carbon-muffler turned into a cut towards the front out from under the flat edge, giving the scooter a spectacular look. It offers all 90-125cc small frame optics and substantial upgrade performance wise. With a 166 or modified 136, the Down & Forward blasts out the heat, making it an ideal system for top speed racing on long stretches. Weak moments in lower RPM can be balanced out with the right transmission. The SIMONINI 180 adds to this, not just optically. Pure power with even hotter tempos like Down & Forward, the 180 is not for weak nerves. In order to use the system, the cylinder must be mounted in a 180 bend, which will put the exhaust towards the front. Prize here is improved washing and the exact movement of gas used. More cylinders (for example, the 133er DoA) are not really cut out for spinning, you will need heavy modifications to the chassis. Result: The Italian response to PM40 and co. High end power system with great price/performance ratio. Racing exhaust / steel / aluminum or carbon- silencer / left hand, down and forward or turned by 180 Steel, clear paint, aluminum or (bottom and forward models) carbon- silencer, depending on the design, Galvanized manifold and spring connection. Jets and ignition adjustment are a must. SIP TIP: 75-130 cc adjustment cylinder, SHB carburetor 19-24 mm, longer transmission and reinforced clutch / PK XL clutch is recommended. A clean gear degree with ZIRRI or DRT auxiliary shaft / gears is also a really good combination Good. SIP user community “321sultan (on the art without 40300200..):” Fresh sound and goes way out in the high range. At least 1000 rpm more.: SIP user community “real_himself” (on the art without 40309000..): “This part is incredible takes my Malle 136 to the top of the class No other part matches this in its range of price.” SIP user community “tomnold” (on the art without 15400000..): “I mounted this exhaust on my 133 and boy it doesn’t move. The exhaust struts are stuff especially in the rev range. The sound is superior both in lower and above! fields of music to my ears.”
