Fits: KAWASAKI KX250F, SUZUKI RM-Z250, YAMAHA WR250R, YAMAHA YZ250F
There is no such thing as a performance upgrade
The phrase "Silent chain" is used, so it's normal to say it's quiet
I don't know about the word RACING
The price is about 8 times more expensive than OEM, but the structure and material are the same
The weight difference is also a few grams
The fact that it is manufactured by DID means that it's not a quality issue at all
