2002 Yamaha TTR225L Service and Repair Manual
Codes and numbers
TTR225LP is the model code for the 2002 TTR225L. LIT-11616-TT-26 is the Yamaha part number of the service manual that covers it, along with the TT-R225 and TTR225 designations and the 1999, 2000, 2001, 2002 and 2004 model years.
The L designation is the one buyers most often get wrong when ordering, which is why the code is worth reading off the frame rather than assumed from the tank graphics.
What the book contains is the dealer procedure set. Adjustment and maintenance specifications, engine service in the prescribed order, wear and inspection limits, fuel system settings, suspension and braking work, and the electrical section with Yamaha's wiring diagrams. Fault-finding runs from symptom to cause.
Nothing has been rewritten from the original.
