Condition: New Old Stock (NOS) / Original Yamaha Packaging
Brand: Yamaha Genuine Parts (Made in Japan)
Part Number: 437-11610-20 (Full: 437-11610-20-00)
Size: 0.50mm Oversize (2nd O.S.)

Item Overview

This is a rare, authentic New Old Stock (NOS) Yamaha Piston Ring Set for the mid-70s DT100 series. As a genuine factory part, these rings provide the exact metallurgy and tension required for vintage Yamaha two-stroke cylinders. Perfect for high-quality restorations where aftermarket "will-fit" parts are not an option.

Vehicle Fitment

Specifically designed for the following 100cc Yamaha Enduro models:

Yamaha DT100A: 1974
Yamaha DT100B: 1975
Note: May fit other 100cc models of the same era; please verify your specific parts manual.

Technical Specifications

Oversize: +0.50mm (2nd Oversize)
Bore Compatibility: Must be used with a cylinder bored to the second oversize and a matching 0.50mm piston.
Contents: Complete ring set for one (1) piston.

Restoration Notes

Quality: Being "New Old Stock," these parts may show minor "shelf wear" on the outer packaging, but the rings themselves are factory-fresh and have never been installed.
Fitment Warning: These are not standard size. They are intended for engines undergoing a rebuild where the cylinder has been bored 0.50mm over factory specifications.
