Proper break-in is critical in the first 3000 miles. In this break-in period internal engine compo
-
nents will “seat” or mate to one another. These factors will determine engine longevity.
PRIMARY DRIVE
The primary drive delivers power from the engine to the transmission. The standard primary
drive on your Big Bear Chopper is our proprietary enclosed drive system. BDL® open belt drive
is an option.
TRANSMISSION
The transmission delivers the power it receives from the primary drive to the rear wheel by the
final drive belt or chain. The transmission also allows the engine to operate within its limitations
under varying speeds and conditions. Proper gear selection while riding will enhance your enjoy-
ment, safety and help to ensure longevity of your engine.
FINAL DRIVE
The final drive is the last link in the power train and connects the transmission to the rear wheel
via a belt or chain.
