Crankshaft Racing MAZZUCCHELLI (Vespa 200 Rally VSE1T 33997 - P200E, PX200 E, Lusso , MY, Cosa) (Long Stroke)

Upgrade your scooter with the crankshaft racing mazzucchelli (vespa 200 rally vse1t 33997 - p200e, px200 e, lusso , my, cosa) (long stroke), for precision fit and lasting performance. More stroke allows more cubic , which in turn, means more power. That's why most 200er motors, whether race or road tuned, turn to long stroke crankshafts . To balance out stroke , spacers are set in either at the base or head. It's also a simple way to play around with timing. With long stroke crankshafts, the stroke pivot is further from the crankcase axel: with 60 mm shafts, 1.5 mm. The additional 1.5 mm pushes over the top and lower dead center. To keep the piston from the head, head/base spacers can be installed or /MMW heads can be used. Timing changes in any case. Depending on type of race , there are several favored combinations which we've put for you in the technical department. For the MALOSSI 210cc, the following applies: 1.5 mm base compensation: wide rpm range and high PS, lowered torque coupled with late and sudden acceleration. 1.5 mm head compensation: hefty torque and free in lower rpm's, lower top speeds. This is 's touring combination, especially when coupled with a longer transmission. The MAZZUCCHELLI long stroke crankshafts have a substantially intake timing, just like the racing crankshafts. The conrod is partially a special edged conrod, and the lower conrod bearing is a silver bearing. It is also available as a strengthened 'K2D' version. The higher of the K2D alloy means it is to achieve a higher dimension on the crank pins. This means that the torsion resistance is also increased without welding. This is now used on all MAZZUCHELLI full circle crankshafts. Conclusion: A perfect basis for torque touring motors or rpm hefty PS . For those wanting more, we suggest long stroke flowed shafts. Long stroke crankshaft / stroke 60 mm / connecting rod 105-110 / 24/25 mm, M12 Long stroke crankshaft, with ø 95 mm ( side), ø 97.9 mm (disc valve side), partially at 12 o'clock, lower connecting rod bearing = silver bearing, 105 mm connecting rod (125/150 cc) or 110 mm connecting rod (200 cc), 60 mm stroke, oil seal housing 24 mm, bearing housing 25 mm, stump cone with M12 thread, incl. connecting rod bearing. /MMW long stroke head, MALOSSI 210cc and Road exhaust for touring set up, 1.5 mm base gasket, Performance/RZ/DSE exhaust, MALOSSI or POLINI, 28-30 mm carburetor as basics for sport set up. Try out a variety of base/head gaskets to find the right one for your needs. The timings stated above were determined viewing in the direction of the clutch side. That means: "138°/6° after TDC: Inlet timing begins 6° after TDC and stays open for 138°. Please note that the angular degrees given here are approximate values, as the crankshafts are by hand. Manufactured by Mazzucchelli, Vespa, for quality and reliability. Ideal for daily use or long-term preservation.
