It is intended for repair work involving low compression, cylinder blow-through, piston seizure, or cylinder failure, and includes the main components required for a cylinder, piston and gasket rebuild. The kit originates from the Honda Sonic 125 engine platform, which shares the same engine platform as the European CBR125R and Indonesian CS1 4-stroke engines; for CBR125R installation, crankcase surface modification may be required due to differences in cylinder surface design.\u003c\/li\u003e\n\u003cli\u003eSuitable for addressing low compression, piston seizure, cylinder blow-through, or cylinder failure\u003c\/li\u003e\n\u003cli\u003eIncludes cylinder, piston, piston rings, wrist pin, circlips and a full top-end gasket kit\u003c\/li\u003e\n\u003cli\u003eAnodised piston construction supports improved heat resistance and service life\u003c\/li\u003e\n\u003cli\u003eHigh-performance gasket materials support increased reliability\u003c\/li\u003e\n\u003cli\u003eCost-effective aftermarket replacement for original top-end components\u003c\/li\u003e\n\u003cli\u003eModification allows compatibility with both Sonic and CBR engines after correct fitting preparation\u003c\/li\u003e\n\u003cli\u003eBore diameter: 58 mm STD\u003c\/li\u003e\n\u003cli\u003eStroke: 47.2 mm\u003c\/li\u003e\n\u003cli\u003ePiston pin diameter: 13 mm\u003c\/li\u003e\n\u003cli\u003ePiston pin material: Steel\u003c\/li\u003e\n\u003cli\u003eCompression ratio: 11:1\u003c\/li\u003e\n\u003cli\u003eStandard bore size: 58 mm x 47.2 mm stroke\u003c\/li\u003e\n\u003cli\u003eCross-Reference OEM Part Numbers\u003c\/li\u003e\n\u003cli\u003eCylinder: 12100-KGH-900\u003c\/li\u003e\n\u003cli\u003eCylinder base gasket: 12191-KGH-901\u003c\/li\u003e\n\u003cli\u003eCylinder head gasket: 12251-KTY-D30\u003c\/li\u003e\n\u003cli\u003ePiston STD: 13101-KGH-902\u003c\/li\u003e\n\u003cli\u003ePiston pin: 13111-KGH-903\u003c\/li\u003e\n\u003cli\u003ePiston ring set STD: 13011-KGH-305\u003c\/li\u003e\n\u003cli\u003ePiston circlips: 13115-GN5-910\u003c\/li\u003e\n\u003cli\u003eTensioner gasket: 14560-KGH-900\u003c\/li\u003e\n\u003cli\u003eValve stem seal: 12209-GB4-682\u003c\/li\u003e\n\u003cli\u003eVehicle Fitments\u003c\/li\u003e\n\u003cli\u003eHonda CBR125R, 2004–2017\u003c\/li\u003e\n\u003cli\u003eHonda FS125 Sonic, 2001–2008\u003c\/li\u003e\n\u003cli\u003eInstallation Notes\u003c\/li\u003e\n\u003cli\u003eThe cylinder surface design differs slightly between Sonic and CBR125 models\u003c\/li\u003e\n\u003cli\u003eFor CBR125R installation, modification of the crankcase surface is required to eliminate any gap\u003c\/li\u003e\n\u003cli\u003eModification methods may include welding or using a two-component epoxy aluminium adhesive\u003c\/li\u003e\n\u003cli\u003eAfter modification, the cylinder is suitable for use with Sonic and CBR engines\u003c\/li\u003e\n\u003cli\u003ePackage Includes\u003c\/li\u003e\n\u003cli\u003e1 x 58 mm cylinder, 12100-KGH-900\u003c\/li\u003e\n\u003cli\u003e1 x piston\u003c\/li\u003e\n\u003cli\u003e1 x piston ring set\u003c\/li\u003e\n\u003cli\u003e1 x wrist pin\u003c\/li\u003e\n\u003cli\u003e2 x circlips\u003c\/li\u003e\n\u003cli\u003e1 x cylinder base gasket, 12191-KGH-901\u003c\/li\u003e\n\u003cli\u003e1 x cylinder head gasket\u003c\/li\u003e\n\u003cli\u003e1 x tensioner gasket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eNo separate vehicle-fitment table record was supplied for this part.
