Suzuki GN125 parts for repair and restoration
The Suzuki GN125 family includes the GN125E, which Suzuki documented as a 124cc, air-cooled SOHC single in 1982. The parts gathered here have separate GN125 and GN125E applications. A match for an early GN125 does not automatically cover a later GN125E, even when a product appears in this shared collection.
Carburetor bowl repairs
A carburetor passage plug covers GN125 1982–1983 and GN125E 1991–1997. Compare its diameter and shape with the plug in the carburetor you are servicing.
Leaking fork oil seals
The fork oil seal pair measures 32 × 44 × 10.5 mm and covers GN125 1982–1983 and 1991–1997. Measure the old seals if the forks have been replaced; select GN125E seals by their own confirmed application.
Front disc brake pads
For a GN125 with a matching front disc caliper, sintered brake pads cover 1991–1995. Compare pad outline and caliper position. These pads are not a replacement for drum-brake shoes.
Choosing parts for your GN125
Read the whole model code: GN125 and GN125E parts both appear on this page. If yours is a GN125E, you can also browse GN125E parts before checking your year on each product.
Identify the front brake: Disc brake pads work in a matching caliper; shoes belong in a drum. If the front wheel or brake has been swapped, choose the part for the fitted assembly.
Measure the fork seal: The pair here is 32 × 44 × 10.5 mm. The first number is the inside diameter, then the outside diameter and thickness. Match the actual seal and fork before ordering.
Building a custom GN125?
For a GN125 street build, universal handlebars and grips and mirrors and adaptors can change the riding position. Measure the bars and mirror mounts, then check cable travel and steering clearance. Some universal pieces need modification.

Suzuki GN125 Parts questions
Are GN125E parts included in this GN125 collection?
Yes. This collection includes both GN125 and GN125E applications. Select your complete model and year, then check the specific part because the two designations are not a blanket fitment match.
What size fork oil seals fit a GN125?
The fork oil seal pair here measures 32 × 44 × 10.5 mm and covers GN125 1982–1983 and 1991–1997. Compare the removed seals if the forks may have been changed. For a GN125E, choose seals with a confirmed GN125E application.
Will the front brake pads work if my GN125 has a drum brake?
No. These are disc brake pads for a matching caliper. If your bike has a front drum, choose shoes for that drum and its year.
Can I use the same carburetor passage plug on a GN125E?
The passage plug here covers GN125 1982–1983 and GN125E 1991–1997. Confirm the fitted carburetor and compare the plug's size and shape before ordering.
