Parts Catalogue Pdf: Yamaha Mio Mxi 125

The Yamaha Mio MXi 125 (often designated by the model code AL125FC) represents a significant milestone in Yamaha's scooter lineup, transitioning from traditional carbureted systems to sophisticated fuel injection. Understanding its parts catalogue—often distributed as a PDF—is more than just a maintenance exercise; it is a deep dive into the engineering philosophy that made this liquid-cooled scooter a favorite for urban commuting. The Architecture of the Parts Catalogue

The Yamaha Mio MXi 125 parts catalogue is typically structured into three primary domains: Engine, Chassis, and Electrical. Each section uses high-detail exploded view diagrams that allow owners to identify every nut, bolt, and gasket by a unique 12-digit OEM part number. 1. The Engine Domain: Liquid-Cooled Precision yamaha mio mxi 125 parts catalogue pdf

The MXi 125 was one of the first in its class to feature a liquid-cooled 4-stroke SOHC engine. The catalogue details: The Yamaha Mio MXi 125 (often designated by

While I cannot directly provide or link to a downloadable PDF file (as that would likely violate copyright), I can give you a solid, actionable report on how to obtain the Yamaha Mio MXi 125 Parts Catalogue PDF, what to expect inside, and how to use it effectively.

Section 1: Engine (Jug, Head, Crank)

  • Why it’s critical: The Mio MXi is a 4-stroke SOHC engine. The catalogue details the timing chain tensioner assembly and valve train.
  • Key Insight: Many DIY mechanics struggle with the oil seals. The catalogue specifically highlights the Oil Seal (Crankcase) and O-rings, preventing oil leaks that are common on older Mios.
  • Piston Kits: The catalogue differentiates between standard bore and oversize pistons (OS: 0.25, 0.50, 0.75, 1.00mm), which is vital for engine rebuilding.

Scenario B: Rebuilding the Front Brake Caliper

  1. Navigate to "Front Brake" section.
  2. Zoom into the caliper diagram.
  3. You will see the piston seal (dust seal), piston, and bleed screw.
  4. Critical: The parts catalogue will explicitly tell you if the piston is sold separately or if you must buy the entire caliper assembly. Many riders waste money buying a whole caliper when a $2 seal kit is what they need (though note: Yamaha often sells seals only in the "master cylinder" kit).

Scenario A: Changing the CVT Belt

  1. Open the PDF and navigate to the "Transmission" section (usually diagram C or D).
  2. Locate the exploded view of the CVT case.
  3. Find the belt on the diagram (Reference #12, for example).
  4. Note the Part Number: B94-E7641-00 (Example only – check your actual catalogue).
  5. Note the Qty: 1.
  6. While you are there, check the diagram for related parts you should replace simultaneously: drive face nut, slider weights (rollers), and the CVT case gasket.

Where to Find the PDF

Since this is a legacy model, you won't find this catalogue on the main Yamaha consumer website. Instead, look for it in:

  • Online Motorcycle Forums: Communities dedicated to Yamaha Underbone scooters often have a "Library" or "Downloads" section.
  • Spare Parts Retailers: Some authorized dealers publish technical literature on their business websites.
  • Scribd or DocPlayer: Many user-uploaded technical documents are hosted on document-sharing platforms.
