Up for sale is a factory Suzuki RM125 service manual. This one was bought specifically for the 1999 model (RM125X) but likely is very similar for a lot of other years (I believe is applicable for 1996-2000), I'm just not sure.
This is a printed booklet and is the real deal factory / shop service manual (part number 99011-36E53-03A), used by dealerships, with all the procedures, specifications, torque values, and the tuning section. This is not a Clymer or other off-brand service manual. It was never really even used (bike got stolen), it's not all dirty and oily except for a little stain on the cover page from being in the garage.
This is the same one sold on repairmanual.com for about $60
To sweeten the deal I can throw in a dirt bike triangle stand,
and I think I may have the RM125 rear side plastic panels too somewhere, and maybe even a carb kit and spark plug if I can find all that stuff. These are the only things I have left since the bike was stolen...
