The Beta 2/4 stroke chain runs very close to inside of the frame.
TMD inner Frame Guard protects the inside of the frame and guides the chain onto the countershaft sprocket.
The chain often drags and grinds away the inside of the frame and where the sub frame bolted.
An upper frame pad is included in the design.
You must remove or modify stock plastic countershaft cover if you plan to use it.
We recommend you use our Case Saver / Hydraulic slave cylinder protector for the ultimate protection
