Suzuki UW125, UW125FS-I, UW125FSC-I, HAYATE 125 2010 Parts Catalog

I have lost count of the hours I’ve wasted chasing wrong part numbers from aftermarket websites. You get a gasket that doesn’t match, a piston ring that’s half a millimeter off, and suddenly you are pulling the engine apart again. That is not how I run my shop, and it is not how you should be working either. This Suzuki UW125, UW125FS-I, UW125FSC-I, HAYATE 125 2010 Parts Catalog is the real thing — 78 pages of OEM factory part numbers, not some photocopy or third-party guesswork. It covers the UW125, UW125FS-I, UW125FSC-I, and the HAYATE 125. If you are holding this, you have exactly what Suzuki put in their own parts bins.

Engine Section – What the Factory Lists

The first major section is ENGINE. You will find exploded diagrams for the cylinder head, crankcase, clutch, oil pump, and all internal components. Every part number is Suzuki genuine. Need a gasket set? It is there. Need the exact main bearing part number? Page 1 of the index points you right to it. The manual uses millimeter measurements for dimensions, but I will add a note: always double-check with a caliper before ordering. The manual also includes a modification notice (page 3) warning that some spare parts differ from production models for administrative reasons — that is the kind of critical info aftermarket catalogs leave out.

Transmission – Gears, Shafts, and Bearings

TRANSMISSION covers the gearbox, shift forks, output shaft, and drive chain components. If you are rebuilding a UW125FS-I gearbox, you will see each gear listed with its tooth count (NT) and a part number that matches Suzuki’s bin inventory. The catalog warns that rubber hoses and vinyl tubes must be cut to the specified length — not approximated. That matters when you are replacing a vent hose on a HAYATE 125 and the wrong length causes a kink. I have seen it happen.

Electrical – Wiring Harness and Components

ELECTRICAL section gives you the part numbers for the CDI unit, stator, regulator/rectifier, switches, and the main wiring harness. The manual includes a parts color chart (STD.COLOR CHART) with codes like 019 SUPER BLACK and 291 BLACK (ACRYLIC-MELAMINE) — so if you are restoring a frame and need the correct paint code for the electrical cover, it is here. This is not a wiring diagram — that is in the service manual — but for ordering the exact sensors and connectors, this catalog saves you from buying the wrong parts.

Body – Frame, Panels, and Trim

BODY section lists everything from the front fender to the tail light assembly. Part numbers are segmented by left/right side (LH/RH), and the illustrations show assembly order. If you are piecing together a UW125FSC-I that was parted out, you can use this to find the correct bracket, bolt, or side cover. The manual explicitly states the drawings are for part reference, not assembly — so do not try to rebuild the bike from these illustrations alone. That is what the Suzuki SERVICE MANUAL is for.

Parts Number Index – Stop Guessing

The last section, PARTS NUMBER INDEX, is a quick lookup by part number. You have a worn bearing with a number stamped on it? Cross-reference it here to find the quantity and where it goes. This is the part that saves real time when you are on the floor with a greasy rag and a phone ordering parts.

FAQ

Does this catalog include part prices?

No. It lists part numbers and quantities. Prices are set by your local Suzuki dealer or distributor.

Can I use this manual as a replacement for a service manual?

Absolutely not. This is a parts catalog — it tells you which part to order, not how to install it. For torque specs, assembly procedures, and diagnostic steps, you need the official Suzuki SERVICE MANUAL. The preface on page 3 even warns: “Note that the drawings on the illustration page are for ready reference of spare parts number, not to be used as an assembly manual. When assembling, use SUZUKI SERVICE MANUAL.” Do not skip that step.

If you are working on a Suzuki UW125, UW125FS-I, UW125FSC-I, or HAYATE 125, this is the only parts catalog you need. It is a 78-page factory document, published in 2010, and it is scanned from the original Suzuki print — not a re-typed version with errors. You can browse it on your tablet or print out the page you need for the workbench. Download the Factory Manual and start ordering the right part the first time.
