Yamaha Moro 07 Drivetrain: Read the XT 12-Speed Parts as a Complete Record
Yamaha Moro 07 drivetrain identification starts with the complete XT 12-speed record: a 36T Praxis chainring, named Shimano shifter and derailleur, and a 10–51T cassette. Keeping the model codes with those numbers makes a component enquiry clearer than asking only whether the bicycle has “XT”.
Read the Yamaha Moro 07 drivetrain model codes
The shift-lever entry is SL-M8100-R XT, 12-speed. The rear derailleur is RD-M8100 XT SGS, also listed for twelve speeds. These are distinct components in the source. A Yamaha Moro 07 Shimano XT description should retain both entries instead of assuming one XT marking identifies the entire drivetrain.
The source is a manufacturer MORO-07 factsheet, not an inspection of a particular bicycle. An offered bike may need its own component markings checked against this record. A changed part is something to identify, rather than a reason to extend the source into an unsupported claim about compatibility or original equipment on every generation.
Retain the front ring and complete cassette sequence
The Yamaha Moro 07 36T chainring is named Praxis. At the rear, the table identifies a CS-M8100-12 XT, 12-speed HYPERGLIDE+ cassette. Its stated sequence is 10, 12, 14, 16, 18, 21, 24, 28, 33, 39, 45 and 51 teeth. Recording that sequence preserves more information than the endpoints alone.
Yamaha Moro 07 10-51 cassette terminology describes the rear range; it should not absorb the separate 36T front-ring entry. This article does not turn the combination into a climbing-performance promise, a battery-range estimate or approval for changing either end of the gearing. Those conclusions need more than the equipment list.
Distinguish crank length from tooth counts
Yamaha Moro 07 crank length is listed as 165mm on a Praxis AL6000 crank entry with bolts. The millimetre value describes the crank record, while 36T describes the chainring. The same table names a KMC e12 Turbo EPT chain for twelve speeds. Keep the maker and chain wording as printed rather than transferring the Wabash factsheet’s different chain entry into this one.
For an enquiry, supply the actual bicycle identity and the component marking you want checked alongside these codes. The published list helps ask a precise question, but does not establish wear, adjustment, servicing history or the correct replacement for a component that has changed.
The PAS museum photograph illustrates historical Yamaha context, while the MORO-07 component table supports this specific drivetrain reference. Broader background remains in the existing Yamaha pages. Yamaha topic; Yamaha introduction.
FAQ
Which crank length does this MORO-07 record list?
The Praxis AL6000 crank entry lists a 165mm length.
Does one XT marking identify every drivetrain component?
No. The source separately names the shifter, derailleur and cassette.
Does this list approve a different cassette?
No. It records equipment without supplying a replacement-parts approval.
