To further increase the high performance of the engine, the cylinder is made in a special aluminium alloy that ensures high rigidity levels even at high temperature such the one developed under an intense use.\u003c\/p\u003e\u003cp\u003eTo obtain high dependability, the cylinder barrel features a nickel and silicon carbide coating that guarantees wear resistance. The specifi cally designed piston is made in materials that keep unaltered their mechanical and shape features even at very high temperature. Its special geometry has allowed us to obtain a light piston that reduces inertia and allows the engine to reach very high speed.\u003c\/p\u003e\u003cp\u003eThe super-fi nished piston ring, made in spheroidal graphite cast iron with chrome coating, top off this piston-cylinder assy that combines performance and dependability.\u003c\/p\u003e\u003cp\u003eWARNING INSTALL PART NO. 9924240 EXCLUSIVELY IF MATCHED TO CRANKSHAFT 9920410\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eScope of delivery:\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e1 Combustion chamber cover for AM6\u003c\/p\u003e\u003cp\u003e1 Cylinder Ø 50 Racing Aluminium - Stroke 44 mm (only for part no. 9924240)\u003c\/p\u003e\u003cp\u003e1 Cylinder Ø 50 Racing Aluminium - Stroke 39 mm (only for part no. 9924130)\u003c\/p\u003e\u003cp\u003e1 Lightweight piston Ø 50 Racing AM6\u003c\/p\u003e\u003cp\u003e1 Chromed piston ring Ø 50 x 1\u003c\/p\u003e\u003cp\u003e1 Bushing for reduction Exhaust Ø 28 mm\u003c\/p\u003e\u003cp\u003e1 Bushing for reduction Exhaust Ø 32 mm\u003c\/p\u003e\u003cp\u003e1 Hex.head screw M14 x 1.25; L = 11 Water drain\u003c\/p\u003e\u003cp\u003e1 Adapter for head H2O (GAS 1\/8)\u003c\/p\u003e\u003cp\u003e1 Gudgeon pin 12 x 40\u003c\/p\u003e\u003cp\u003e2 Gudgeon pin circlip Ø 12 AC\u003c\/p\u003e\u003cp\u003e1 Roller cage Ø 12 x 15 x 15\u003c\/p\u003e\u003cp\u003e1 O-ring Ø 104.37 x 3.53 Shaped\u003c\/p\u003e\u003cp\u003e1 Gasket for water drain screw Ø 14.1 x 22 x 1\u003c\/p\u003e\u003cp\u003e1 Compression seal O-ring Ø 53.7 x 1.78 Viton \u003c\/p\u003e\u003cp\u003e8 Green viton O-ring Ø 7.66 x 1.78 \u003c\/p\u003e\u003cp\u003e1 Green viton O-ring Ø 22.22 x 2.62 \u003c\/p\u003e\u003cp\u003e1 Cylinder base gasket \u003c\/p\u003e\u003cp\u003e1 green viton O-ring Ø 32 x 2.5 \u003c\/p\u003e\u003cp\u003e1 Crankshaft w\/stroke 44 mm (only for part no. 9924240) \u003c\/p\u003e\u003cp\u003e1 Combustion chamber, 44 mm stroke (only for part no. 9924240) \u003c\/p\u003e\u003cp\u003e1 Combustion chamber (only for part no. 9924130) \u003c\/p\u003e\u003cp\u003e1 Woodruff key, 0.6 (only for part no. 9924240) \u003c\/p\u003e\u003cp\u003e1 Bearing SKF 6204ETN9\/C3H (only for part no. 9924240) \u003c\/p\u003e\u003cp\u003e1 Bearing SKF 6303TN9\/C3 (only for part no. 9924240)\u003c\/p\u003e\u003cp\u003eNOTE: IT IS NECESSARY TO OPEN THE CRANKCASE TO FIT THIS CRANKSHAFT, IT IS THEREFORE RECOMMENDED TO HAVE QUALIFIED MECHANICS PERFORM THIS JOB TO AVOID OPERATION AND RELIABILITY PROBLEMS.\u003c\/p\u003e\u003cp\u003eStroke mm\u003c\/p\u003e\u003cp\u003eSquish mm\u003c\/p\u003e\u003cp\u003eBore mm\u003c\/p\u003e\u003cp\u003eDisplacement cm3\u003c\/p\u003e\u003cp\u003eTiming diagram                                exhaust: 190°\u003c\/p\u003e\u003cp\u003eTiming diagram  transfer                   ports   : 130°\u003c\/p\u003e\u003cp\u003eCompression ratio                          geometric  14,8:1  \/ actual 8,1:1  \u003c\/p\u003e\u003cp\u003eRecommended spark advance          17° (*)\u003c\/p\u003e\u003cp\u003e(*) to obtain an advance of 17°, you need to use the supplied Woodruff key.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"TOP PERFORMANCES","offers":[{"title":"Default Title","offer_id":58185259745628,"sku":"1127334","price":877.44,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/5072\/8284\/files\/800Wx800H-1127334-1.jpg?v=1783062934","url":"https:\/\/checkout.xparts.weostores.com\/products\/bhir-1127334","provider":"xparts","version":"1.0","type":"link"}
