Crankshaft MAZZUCCHELLI (stroke 58mm, conrod 107mm, pin 16mm, cone large 25mm) (Lambretta DL, GP)

Engineered for riders who expect more, the crankshaft mazzucchelli (stroke 58mm, conrod 107mm, pin 16mm, cone large 25mm) (lambretta dl, gp) dependable performance. The crankshaft is one of the most heavily used components on a scooter. It turns several thousands of times per minute, and the performance of an engine depends on its quality. Minimum production tolerances, high rev endurance, low bearing clearance and exceptionally high durability of the crankshaft are the basis for optimum engine tuning. For this reason we only offer crankshafts that are made in Italy and which through their uncompromising levels of quality. The crankshafts have a stroke of 58mm and a 107 series con-rod. The TV175 is fitted as with the 116 series con-rod. Replacing the 107mm with a 110m con-rod is in order to make the engine run more quietly. The longer con-rod is by a 3mm base gasket. The lighter racing crankshafts have a con-rod which contributes to turbulence. When using a full circle crankshaft , the charge level and primary compression (for this reason we use the designation HPC = high primary compression). In combination with a long stroke of 60 or 62mm this results in further torque and also boosts performance. Both types of crankshaft are specially for peak performance and are also made from extremely high quality and hard wearing . This means they are optimal for engines and high performance setups. In to the Vespa, the cone for the Lambretta is only available in two which can be swapped with each other. The larger cone ( after the oil seal seat) was originally only in the engine of the DL/GP, the smaller cone on all the other models tapers after the oil seal seat to 21mm. Under high and/or a high numbers of revs, however, forces impact on the entire cone, which the small point of the 21mm cone is not always able to withstand. As a rule, the following applies here: the thicker the cone, the more stable and/or more for tuning . With engines it is important to use a crankshaft with a thick DL/GP cone. Order the oil seal and at the same time! The perfect crankshaft for TS 1 engines, a solid cone and high quality provide maximum durability of the engine. Also a top choice for converting the small LI/SX crankshaft to electronic . Manufactured by Mazzucchelli, for quality and reliability. A must-have for any scooter enthusiast.
