Description

BGM PRO 177/187 cc (piston made by Meteor) - Vespa PX125, PX150, Cosa125, Cosa150, GTR125, TS125, Sprint Fast (VLB1T 0150001-) The BGM PRO cylinder 177 is made of aluminum coated hard ceramic with a 63-bore mm. The coating (nickel-silicon carbide) ensures an extremely hard and durable shirt. The high percentage of silicon of the piston ensures a reduced thermal expansion, a high wear resistance and a decidedly considerable thermal stability. Two elastic bands of 1 mm thick minimize friction, all to the advantage of power and sealing speed. The cylinder channel with four main decanting and two boost port is designed to exert a high pressure at low speed regimes. With a stroke of 57 mm we have a 118 ° decanting and a timing of 171 ° exhaust timing. The kit of the cylinder is designed as a plug & play solution, simple to insert with carburetor SI and BGM Big Box Touring, the power is about 15 hp and the torque is 17-19 Nm on the rear wheel. With further steps to strengthen you reach 25 hp and you have no more problems. The low power consumption and the relative high flow are an added bonus. Cylinder Material: Aluminum Shirt: coated with silicon carbide-nickel Bore: Ø 63 mm Stroke: 57/60 mm displacement: 177/187 ccm Piston: cast piston with high percentage of silicon and two steel bands from 1 mm timings ( stroke 57 mm): racking 118 °, 171 ° exhaust Squish recommended: 0.8- 1, 2 mm The countersunk channels at the base of the cylinder have a cover that determines the correspondence with the channels on the engine crankcase. The cover can be easily removed for use of the entire channel section. The headboard is made with full CNC machining. To ensure the perfect centering, the combustion chamber is placed in the cylinder to a depth of 4 mm. In addition, the adjustment of the squish is greatly facilitated and the seal is constantly guaranteed. At the center is a thread for the mounting of a temperature sensor. In the Downloads section you will find suggestions for different phases of enhancement, proposals on the nozzles and diagrams. The cover can be easily removed for use of the entire channel section.
