it will use a 2 cycle 2 stroke oil. make sure it is recommended for water cooled engines. best place to get it is your local motorsports shop. becareful what you choose for they all run different. i have a cr 250 and run amsoil 10-40 full synthetic. i would recomend amsoil i used to run belray and had a ton of problems with fouling and build up. since running amsoil my bike runs alot better. check your manual or as a service rep and the shop about the oil/gas ratio. hope this helps
There is no rm 125 fourstroke they make a drz.
If you are talking a RM 125 then I would use Redline shockproof gear oil ......IT IS AMAZING.
10W40 or on what type of tranny it has
174cc per leg
Suzuki 4- stroke motorcycle engine oil Sp-4A SAE 10W - 40
According to race tech, for a 170 lb rider, use 285cc per fork.
You should use Suzuki's 10W 40, but it is safe to use another brand of 10w 40 as long as it is a motorcycle motor oil. You will need an oil with wet clutch protection.
GL-5 for gear oil and for engine oil use 10W-30
1.5l of 10w-40
10w30 motor oil
Use 100% synthetic oil in the exact weight as recommended by the manufacture of the engine.
depends what climate your running it at. 30:1
