Scooter Cylinder Head Studs 139QMA 139QMB (STDCH010) FROM CMPO ** NEW ** BOLT : STDCH010 DESCRIPTION ["Cylinder head studs are threaded fasteners that secure the cylinder head to the engine block in a motorcycle. They provide a robust and reliable connection, ensuring that the cylinder head remains tightly sealed against the engine block. Made from high-strength materials like steel or alloy, these studs withstand the high pressures and temperatures within the engine. Proper installation and torque of cylinder head studs are crucial for maintaining engine compression, preventing leaks, and ensuring optimal engine performance and longevity.","In the category of Engines and Engine Parts > Plugs, Bolts and Fixings > Cylinder Head Bolts\/Studs"]SPECIFICATIONSLength of Outer Cable: 177mmThread Diameter: M8 Compatible with AJSModena 50 ZN50QT-27 AliszeFX50 50 CDI YY50QT-15(ALISZE), Jazy 50 CDI YY50QT-21(ALISZE) AxoryRallox JSD50QT-13(AXORY) BTMBT49QT-9, BT49QT-12, Sprint BT49QT-12C1 BaotianApollo 10 BT49QT-9(A10), Apollo 12 BT49QT-9(A12), BT49QT-9, BT49QT-12, BT50QT-9, Chase 49 BT49QT-7, Eagle 50 BT49QT-9F3, Eagle 50 GT BT49QT-9F3(GT), Monza 50 BT49QT-21A3, Rebel 49 BT49QT-12C1, Rocky BT49QT-12E1, Scout 50 BT50QT-9, Tanco 50 2 BT49QT-12, Tommy 50 BT49QT-11 BeelineVeloce GT Race VELOCEGT, Veloce GT VELOCEGT BeneroBT49QT-9 BT49QT-9D1 BenzhouYY50QT, YY50QT-10, YY50QT-14, YY50QT-15, YY50QT-21 CTMCTM50QT-7 ChitumaCTM50QT-7 Direct Bikes50cc Milan E3 DB50QT-30A, 50cc Ninja DB50QT-6, 50cc Ninja E3 DB50QT-15B, 50cc Retro DB50QT-7, 50cc Retro DB50QT-A, 50cc Scorpion E3 DB50QT-32A, 50cc Sports DB50QT-5, 50cc Sports DB50QT-11, 50cc Tommy E3 DB50QT-E, 50cc Viper DB50QT-25, 50cc Viper E3 DB50QT-32, DB50QT-16 EurockaMATADOR 50 4T LED JJ50QT-17(EUROCKA) Flex TechCityliner 50 BT50QT-9(FLEX TECH), Firenze 25/50 YY50QT-21(FT), Hurrican X2 JL50QT-4(FLEX TECH), Jive BT49QT-11(FLEX TECH), Panter I JL50QT-4(FT), Sprint 50 BT49QT-9(FLEX TECH), Topdrive 50 YY50QT-14(FT), VRR-50 YY50QT-10C, Venus II HT50QT-6(FLEX TECH) GuobenMadness 50 LB50QT-21 HaizhimengGP1 (4 Stroke) HZM50QT-16, LB50QT-21 HanglongHL50QT-16, LB50QT-16, LB50QT-21 HaotianBubble 50 HT50QT-9 HuatianHT50QT-10, HT50QT-16, Sport 50cc HT50QT-6, Sport 50cc HT50QT-7, Sport 50cc HT50QT-25 IMF IndustrieNew Pach 51 NEWPACH51, Pach 51 PACH51, Two 4 TWO4 JMSTARJSD50QT-13 Jack FoxCity Star YY50QT(JF), Retro Cruiser YY50QT-21(JF), Retro Star YY50QT-15(JF) JiajueMATADOR 50 JJ50QT-17A, Revenge JJ50QT-3, Revenge JJ50QT-3(A) JinlunJL50QT-5, JL50QT-6, JL50QT-7 JonwayAgility 50 YY50QT-6, Madness 50 YY50QT-31 KeewayHURRICANE 50 (4T) HURRICANE (4T) KymcoAgility 50 Leike50GY-2 LK50GY-2 LexmotoDiablo50 LJ50QT-9M, Echo 50 E4 LJ50QT-5L, Echo 50 Euro 5 LJ50QT-9L-E5, Echo 50 LJ50QT-3L, FM 50 WY50QT-111, FMR 50 WY50QT-58R, Flash 50 ZN50QT-15A, Milano 50 FT50QT-27, Molly 50 DFE50QT-3, Scout 49 BT49QT-9LEX, Tommy 50 ZN50QT-A, Tommy 50 ZN50QT-E, Tornado 50 SB50QT-16(B08), Valencia 50 ZN50QT-K LifanAero 50 (4T) LF50QT-26 LingbenLB50QT-21 LintexHT50QT-12 HT50QT-12(LINTEX), HT50QT-16, HT50QT-33 LongjiaLJ50QT-3L LJ50QT-3L(LJ), LJ50QT-3M, LJ50QT-9L MKS EcobikePanter I BT50QT-9(MKS) Moto ZetaRally 50 SC RALLYSC Nova MotorsCity Star YY50QT(NM), Retro Cruiser YY50QT-21(NM), Retro Star YY50QT-15(NM) PulseForce 50 HT50QT-36, Lightspeed 2 50 WY50QT-58, Lightspeed 50 HT50QT-25, Phantom 50 ZN50QT-32A, Rage 50 LK50GY-2, Rhythm 50 SB50QT-16, Scout 49 BT49QT-9, Storm 50 HT50QT-6, Tanco 49 BT49QT-12, Tanco 50 BT49QT-12, Zoom 50 HT50QT-7 QingqiQM50QT-6A RazzoTanco 50 BT49QT-12 RectoRetro BT49QT-11 RexRS450 SanbenTornado 50 SB50QT-16(B08) Scooter DevilBlue Dragon 50-4T YB50QT-21(SD), Cruiser 50-4T BQ50QT-40, Mosquito 50-4T YY50QT(SD), Warrior 50 BQ50QT-21 SinnisFalcon 50 QM50QT-2 Star QuadJL50QT-5 JL50QT-5(STAR QUAD) SukidaLutetia SK50QT-19, Roma SK50QT-9, Top 1 SK50QT, Viper 50 SK50QT-21 SuperbykeMPED 50 MPED50 TamorettiRetro 50 RETRO50 ViarelliSprint BT49QT-12C1 WK BikesBellissima 50 HT50QT-12, GO50 JJ50QT-3(WK), Mii 50 HT50QT-33(WK), WASP 50 JJ50QT-17(WK) WangyeWY50QT-16, WY50QT-16(B08) XingyuePhoenix 50 LLX50QT YamatiGP1 (4T) HZM50QT-16 4T YibenHurricane 50 YB50QT-9, Scout 50 YB50QT-3, Storm 50 YB50QT-6, YB50QT-21 ZenncoMatrix WY50QT-16 ZippTriad BT49QT-12F1 ZnenFlash 50 ZN50QT-15A, Speedy Streetfighter ZN50QT-11, Tommy 50 ZN50QT-A, ZN50QT-11, ZN50QT-E
