Spark plug for '97 YZ 125?

[Ryan314]

What spark plugs do I need for my '97 YZ 125? Bought the bike a few days ago... I have a service manual on order but would like to buy some new plugs tommorow.

Thanks.

NGK makes great plugs and some that would fit your bike are the br(8 or 9)es and br (8 or 9) eg

the eg is a racing plug, i ride the eg on the track, and the es on trails. the eg runs hotter and is more of a performance plug, it doesnt foul near as much. although it is a little more expensive, that is why i only ride them on the track.
