The PX80 engine case corresponds to a PX125/150 engine case with a narrower cylinder base. Original 80 and 100 cc cylinders and crankshafts with 48 mm stroke were used. A good combination is the PX80 racing shaft, a SIP road exhaust and a 24 SI carburettor. Here, the cylinder base is turned to fit the PX80 engine housing. However, this also requires a crankshaft with 57 mm stroke and a longer gear ratio.
Robert Kremer, ScooterandSpareparts Kissing, November 2011 :"I built this reworked POLINI 2-transfer cylinder into a scooter for one of my customers. When the 3rd cylinder transfer port is blown (gasket), the DR can be also be driven on engines with 2 transfer ports. With using the POLINI head and adapting the cylinder transfer port to POLINI 177 dimensions, the 177 gets more power, but won't be completely indestructible. The OLYMPIA 177 is identical to the DR 177er, and is a very good alternative if the DR if not available. Cast Iron/ 63mm Bore/ 7 Transfers/ 177.68ccmCast iron cylinder, 57mm stroke, 7 transfers, pistons with 2 piston rings, exhaust with additional auxilliary outlets, original DR cylinder head and gasket set included in delivery.
The speed at which the Vespa smallframe engine has been developing recently is truly breath-taking. Newly constructed engine casings with complementary cylinder kits can be purchased for self-assembly and represent a tuning basis with, earlier completely unknown, potential being available. The BFA 288 represents the most powerful aftermarket tuning kit currently available for the smallframe engine. In principle it is simply the BFA 306 concept for the Vespa largeframe models, innovatively transferred to the confines of the Vespa smallframe engine casings. The engine caseThe BFA engine casings for Vespa smallframe models are especially massively constructed and have a high-end production process.
Product descriptionLong anticipated and now a reality : The QUATTRINI M-232/M-244 performance cylinder , for the 'big-block' PX 200 motor is finally available! Surprisingly perhaps, no extra modifications are required to enjoy this cylinders performance, in spite of the whopping nicasil lined 72mm bore. The design of the cooling fins on the cylinder head have a similar fan-shaped arrangement to that found on certain old KREIDLER mopeds. The cylinder head nuts should be tightened, with a torque wrench, to a value of 20 Nm. If the SIP Performance shafts are used (SIP Art.-Nr.45021700, 45021710), the small half does not have to be spindled.
The 130cc DR is a solid and well made touring cylinder with 2 side transfer ports and a tripartite boost port. This is also ideal as a replacement cylinder for the original 125er cylinder with the extra cubic capacity. The OLYMPIA 130cc is similar to the DR 130cc and a good alternative if the DR has delivery problems. Cast iron/57mm bore/ 51mm capacity/ 7 transfers / 130,14 ccCast iron cylinder, 51mm stroke, 7 transfers, piston with 2 piston rings, 8mm exhaust studs, original DR cylinder head and gasket set included. Transfer ports do not have to be modified.
The Italian tuning firm MALOSSI have taken the motor tuning credo that ?Nothing beats capacity, except more capacity? The 218cc cylinder is compatible with both the original PIAGGIO and the MALOSSI 'V-4' performance cylinder heads. The kit available for motors with carburettors includes a sharper camshaft and the MALOSSI 'V-4' cylinder head, as well as the complete cylinder kit, as part of the package. The tuning kit for motors equipped with fuel-injection also includes the 'FORCEMASTER 2' fuel-injection control module, also produced by MALOSSI. SIP-TIP : For safe and enduring use of this cylinder kit we recommend you replace the main jet, on carburettor motors, with one that is approximately 10% larger in size.
Product descriptionRacing cylinder with 244 cc for the Vespa 200 models from VMC. The VMC cylinder in the 200 class throws a whopping 244 cc with 60 mm stroke into the ring. PowerfulHigh torqueSuitable for everyday useThe VMC Explorer has an exceptional and well-functioning overflow system. They are supported by three boost ports, of which the two outer ones are more a mixture of boost port and overflow channel. The cylinder has a small cylinder base that gives the piston approx.
A powerful statement here is the strong and sporty 215cc, and gets brutal 224ccm with long stroke shaft and 60mm stroke. Whoever wants more, can simply add a sport exhaust, a modified intake and long stroke shaft to put wings on their Vespa. Different from earlier versions, which were constructed to be used with a long stroke shaft, the newest PINASCO has to be driven with a head or base gasket. Racing cylinder kit with the benefit of a high quality aluminum cylinder, maximal bore, durable nicasil coating and balanced thermal attributes. The casing should be adjusted to the cylinder transfers, though not necessarily in the first step.
The new POLINI cylinder head air flow is perfected through 4 additional cooling ribs. 22159161 on MALOSSI reed valve basis or Art. 22159430 on POLINI reed valve basis) which gets an orderly portion of power out of this kit. Aluninum/ 57 mm bore/ 6 transfers/ 130ccAluminum cylinder, nicasil race, 51 mm stroke, 6 phat transfers, coated piston with 2x 1.5 mm piston rings (chromed S10), perfectly adjusted compression degree, super timing, new POLINI cylinder head delivered including gasket set. The crankcase should be modified to match the larger cylinder transfers.
