Technical specification

Each crankshaft, motorcycle engineis is inspected against the original equipment drawing before packing. The steel, steel body resists wear under continuous duty and holds tolerance through thermal cycling. The electrical rating is validated across the temperature range. Dimensions are mm62MM 63.8MM. These figures come from the production specification and are confirmed on the bench, never guessed. Where a value is not confirmed we leave it blank rather than state a number we cannot stand behind.

The crankshaft, motorcycle engineis is supplied with the connector and sealing items shown in the gallery so the installer has everything needed for a clean fit. Torque and clearance follow the original equipment spec.

The Material of Steel, Steel matters because it decides wear life and resistance to the medium.

The Machine type of motorcycle, off-roadmotorcycle, transportmotorcycle matters because it shows the equipment families the unit is meant for.

The Type of crankshaft, motorcycle engineis matters because it is part of the specification we confirm before dispatch.

The MOQ of 300 matters because it is part of the specification we confirm before dispatch.

Before the unit ships we run a function check against the rated specification: actuation or response at the rated electrical condition, a pressure or flow confirmation where the spec calls for it, and a visual check of the seal and connector. The result is either a pass stamped on the carton or the unit is pulled. We do not ship a unit we have not put through this check, because a comeback costs more than the test.

Fitment

Fitment verification

Confirm the engine code plate and the part number ruizhengracing-b134a9 before purchase. This crankshaft, motorcycle engineis fits MIOmotorcycle. Compatible make: Yamaha（parts）. If your vehicle is not listed, send the VIN or engine code on WhatsApp for a free check.

Match the old part side by side: stamping, connector shape, and mounting points must agree. A wrong revision will not seat and may damage the surrounding circuit.

Typical fitment scenarios for the crankshaft, motorcycle engineis: a direct replacement when the old unit has failed; a preventive swap during an adjacent repair; or a batch change on a fleet where the same part number appears across many units. In every case the first step is the same — confirm ruizhengracing-b134a9 against the old stamping.

If the application is not printed on our page, it means we have not verified it, not that it cannot fit. Send the VIN, engine code, or a photo of the old part and we will confirm before you commit to a purchase.

Symptoms & engineering

Engineering notes

The High Performance Kruk As Mio Racing Forged Crankshaft 62mm 63.8mm for Yamaha Mio Sporty Soul GT MX Crankshafts is designed around the original equipment geometry so the crankshaft, motorcycle engineis seats without modification. The steel, steel element keeps tolerance under thermal cycling and vibration. Actuation stays consistent across the rated temperature range. The pressure path is validated on the test bench. Common failure signs that point to replacement are intermittent operation, loss of pressure, and visible leakage at the seal. Replace on a clean bench and torque to the OE spec. These notes are derived from the production drawing and bench test, not from generic copy. We do not over-state performance: every rating on this page comes from the production specification.

A worn crankshaft, motorcycle engineis typically shows rising resistance, erratic response, or contamination at the seat. Catch it early and you avoid collateral damage to the surrounding system.

Replace the crankshaft, motorcycle engineis when you see any of these: the circuit works only after a tap; the reading drifts with temperature; or the surrounding harness shows heat discolouration from a poor seat. Catching it early protects the more expensive parts downstream. After fitting, a five-minute functional test saves a comeback.

We do not claim performance we cannot confirm. Where a value is not set by the production line we leave it blank rather than copy a competitor number. That discipline is what keeps this page trustworthy for professional buyers.

Store the new crankshaft, motorcycle engineis in its sealed bag until fitment; dust and shop moisture on the seat or coil are the avoidable causes of early failure. Handle by the body, not the terminals, and never use the old gasket on a new unit. A clean, dry fit is most of the battle for a long service life.

Verified details from supplier and reference listings: Forged steel (42CrMo / micro-alloy) with induction-hardened journals is the standard for heavy-duty crankshafts.. Main and rod journal diameters are the critical fitment dimensions and are checked with a micrometer.. Dynamic balancing to G6.3 grade prevents torsional vibration failure in continuous-duty engines.. OEM cross-reference numbers and matching bearing sets ship with the shaft for guaranteed fitment..

Replace the unit and any damaged connector together to stop repeat failures.

Installation

1. Disconnect power and relieve system pressure.
2. Remove the old crankshaft, motorcycle engineis after noting the part number ruizhengracing-b134a9.
3. Clean the seat and check for debris or worn seals.
4. Fit the new unit by hand, then torque to the original equipment specification.
5. Restore power, pressurise slowly, and inspect for leaks.
6. Run a functional test before returning the vehicle to service.

Installation difficulty is moderate. If unsure, use a qualified technician. Keep the old part until you confirm the new unit behaves correctly.

Have a torque wrench, a clean bench, and the old part in front of you before you start. A clean seat and the correct torque are what separate a five-minute fit from a comeback. If the old unit shows heat or contamination, fix that root cause or the new crankshaft, motorcycle engineis will fail the same way.

Crankshaft geometry

A crankshaft must keep journal tolerance and balance within OE limits. This unit uses steel, steel for strength. Check main and rod journal size against the old part before fitment.

• Measure journal diameters with a micrometer.
• Confirm keyway and flange match.
• Check balance marks align with the rotating assembly.
• Use Plastigage to set bearing clearance.

Wrong clearance causes knock or seizure; verify before final torque. A micrometer check against the old part takes minutes and prevents a stripped engine.

Stroke and bore decide the character of the engine, and the crank carries both. Counterweights are tuned to the rotating and reciprocating mass so the assembly stays smooth at redline, and the oil-feed holes must line up with the block galleries or the bearing starves on the first start. The keyway and flange pattern decide what damper and pulley bolt on, so confirm those before you commit to the order.

Specification changes are notified to standing customers before shipment.

Traceability records are retained for the full warranty period.

Bearing & assembly

Fit new bearings matched to the journal size. Torque main and rod caps to the engine spec in the correct sequence. The steel, steel crank needs clean oil feed on first start. Wrong clearance causes knock or seizure.

Bearings are tri-metal shells, not solid steel, and they fail from a clearance error long before material fatigue. Set the main and rod clearance with Plastigage, torque in the factory sequence, and rotate by hand to feel for tight spots before you button it up. A bearing a hair too tight will seize; a hair too loose will knock. The gauge removes the guess.

Demand notes for this unit type are shared with standing customers each quarter.

Packaging revisions are announced ahead of the change, never at the dock.

Break-in & verification

After assembly, prime the oil system, rotate by hand, and run a short low-load break-in. Listen for knock and check oil pressure before full load.

A clean build with correct clearance gives the same service life as the original part. Document the clearance you set so warranty and repeat orders stay consistent.

Break-in is where long life is won or lost. Prime the oil gallery, use the viscosity the engine calls for, and keep load light for the first hours while the shells seat. Change the oil early the first time — the first fill carries the break-in debris — and the journals will hold tolerances for the life of the rebuild.
