Instead of sourcing individual components piecemeal, this convenient package groups everything needed for a structural top and bottom-end restoration into a single box. This system eliminates the uncertainty of high-performance maintenance, restoring factory-spec sealing, mechanical clearance, and operational balance to high-RPM mini engines.\u003c\/p\u003e\n\u003cp\u003eInside the WR101-148 kit, top-end compression is handled by a standard-compression Vertex piston kit complete with rings, wrist pin, and circlips. The bottom-end foundation is anchored by a Hot Rods heavy-duty crankshaft assembly built to stock stroke parameters, which includes the small-end wrist pin bearing. This system is reinforced by robust Hot Rods main bearings and oil seals, a complete transmission bearing array containing an output shaft collar and sprocket lock washer, counter balancer bearings, and a dedicated water pump rebuild assembly. A total engine gasket kit from Vertex seals the entire build from the crankcase up to the cylinder head.\u003c\/p\u003e\n\u003ch3\u003eTop Features: Vertex Complete Engine Rebuild Kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eComplete top and bottom end engine restoration architecture bundled into a single convenient service box.\u003c\/li\u003e\n\u003cli\u003eFeatures a heavy-duty Hot Rods stock-stroke crankshaft paired with a standard-compression Vertex piston configuration.\u003c\/li\u003e\n\u003cli\u003eSupplied with specialized Hot Rods main, transmission, counter balancer, and water pump bearing or seal kits.\u003c\/li\u003e\n\u003cli\u003eIncludes a full Vertex gasket array alongside an entire engine oil seal and O-ring profile to prevent fluids from leaking.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlease cross-reference your specific model sub-type and year range against our fitment index below to ensure precision parts matching before assembly.\u003c\/p\u003e\n\u003ch3\u003eFitment List\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin-top: 15px; margin-bottom: 20px; font-family: inherit;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"border: 1px solid #e2e8f0; padding: 12px; background-color: #f8fafc; text-align: left; font-weight: bold;\"\u003eYear Range\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e2e8f0; padding: 12px; background-color: #f8fafc; text-align: left; font-weight: bold;\"\u003eVehicle Brand\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e2e8f0; padding: 12px; background-color: #f8fafc; text-align: left; font-weight: bold;\"\u003eVehicle Model \u0026amp; Sub-Model\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003e2013-2016\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003e85 SX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003e2017\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003e85 SX (17\/14 Wheels)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003e2014-2017\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003eHusqvarna\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e2e8f0; padding: 12px;\"\u003eTC85 (17\/14 Wheels)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this kit change the engine's original displacement or cylinder bore?\u003c\/strong\u003e\u003cbr\u003eA: No, this engine package retains standard factory configurations.

Always utilize an appropriate crankcase splitter tool. Before dropping the new Hot Rods main bearings into place, cold-freeze the bearings overnight and gently warm the clean engine cases with a heat gun — the thermal differential allows the bearings to drop smoothly into position without damaging the precision bore surfaces.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/new-ktm-85-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 85 SX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/husqvarna-tc-85-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eHusqvarna TC 85 Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-2-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eKTM 2-Stroke Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
