Max,

Thank you for supplying the information and the web link for the front brake pads! I just examined my front brake caliper and confirmed that the Sierra 200 uses Vesrah brake pads VD-312 or SD-312. The VD-312 brake pads are organic, and the SD-312 brake pads are semi-metallic. My motorcycle came equipped with the semi-metallic, VD-312 brake pads. According to the Vesrah parts catalog these brake pads are also used by the Suzuki GP125, and the Hyosung GF125 motorcycles.

Searching the internet I discovered the Hyosung GF125 repair manual at the following url (uniform resource locator).

I can verify that the Sierra 200 uses the Hyosung GF125 front brake caliper. I downloaded the above manual and used the information following page 6-22 to disassemble and inspect my front brake caliper and brake shoes. I will post my findings soon in another thread.

Inspecting my rear brake drum I discovered that the Sierra 200 comes equipped with organic brake shoes that measure 130mm in diameter by 28mm in width. I believe the best aftermarket replacement for this brake shoe is Vesrah part VB-223.

This brake shoe is used by a large number of Yamaha motorcycles. You can discover which motorcycles use a particular Vesrah brake product by typing the part number in the Buyer's Guide box at the Vesrah on-line catalog.
