Yamaha Wabash RT Gearing: Identify the 44T and 11–42T GRX Record

Yamaha Wabash RT gearing is recorded as a 44T chainring with an 11–42T, 11-speed cassette and named Shimano GRX components. Read those entries together when identifying the documented build. They describe the manufacturer’s published equipment record, without proving the condition or installed parts of an individual bicycle.

Read the Yamaha Wabash RT gearing record as a set

The shift-lever line names Shimano RX600, 11-speed. The rear derailleur is listed as GRX RX812. Those model labels help make a parts enquiry specific: “GRX” alone is broader than the combination printed here. The sheet is a record of this build, not a list of every component that may be substituted for it.

The Yamaha Wabash RT 44T chainring is listed under GRX. Keep the front tooth count separate from the number of rear speeds. One identifies the front ring’s teeth; the other describes the cassette’s eleven positions. Calling both simply “44 and 11” would make a comparison note needlessly ambiguous.

Retain the cassette name and endpoints

For the Yamaha Wabash RT 11-42 cassette, the sheet names Shimano CS-M7000 with an 11–42T range and eleven speeds. That supplies the smallest and largest listed tooth counts, but this article does not invent a complete intermediate sprocket sequence. The component code is useful when asking whether a photographed cassette is the one in this record.

A Yamaha Wabash RT Shimano GRX description should not silently turn into a general claim about every Wabash generation or market. The source is the named manufacturer factsheet. Its URL includes a 2022 asset directory; that filename alone does not establish a particular bicycle’s manufacturing year, present equipment or availability.

Preserve the unusual chain spelling

The chain line visibly reads “KMW e11 TURBO EPT”. Preserve that text in a Yamaha Wabash RT drivetrain record enquiry rather than silently changing it to a familiar maker’s name. If the installed chain is marked differently, record that marking and ask for clarification. A plausible correction is still a correction, and this source does not independently establish one.

This is a component-identification reference, not a riding test, replacement approval or forecast of battery range. The separate PAS museum photograph supplies historical brand context. Existing Yamaha pages provide the wider background. Yamaha topic; Yamaha introduction.

FAQ
