In above-mentioned motorcycle engine rocket arm, described lubricated through hole one quantity is two.The quantity that lubricated through hole is set is two, be more convenient for to being lubricated in axis hole, and lubrication effect is more obvious.
In above-mentioned motorcycle engine rocket arm, on described connecting end one, welding is fixed with a contiguous block.Contiguous block for being connected with push rod, is welded to connect piece, make between this rocking arm and push rod be connected more stable.
In above-mentioned motorcycle engine rocket arm, on described body, offer lubricated through hole two, described lubricated through hole two is communicated with axis hole and connecting end one.Offer lubricated through hole two, be convenient to axis hole and connecting end two to be lubricated, thereby make the running of this rocking arm more stable.
In above-mentioned motorcycle engine rocket arm, described body is provided with stiffening rib, and described stiffening rib extends to connecting end two from connecting end one.Stiffening rib is arranged on the inner side of " 7 " font body, make the structure of this rocking arm more firm, running more stable.
In above-mentioned motorcycle engine rocket arm, on described connecting end two, be fixed with the yoke of two protrusions, and be fixed with roller shaft between the yoke of two protrusions, described roller is hinged on roller shaft.
Compared with prior art, due in this rocking arm, on connecting end two, be provided with roller, thereby make the way of contact of rocking arm and engine cam become present rolling friction from original sliding friction, greatly reduced the wearing and tearing between rocking arm and engine cam, thereby made the running of this rocking arm more stable.
