Drive Chain
Inspection
(
Refer to Safety Precautions on pages 44 & 45
)
1. Check slack in the lower drive chain run midway between the
sprockets. Drive chain slack should allow the following vertical
movement by hand:
1” to 1-3/8” (25mm to 35mm)
2. By moving the bike between inspections, check the drive chain slack
at several points along the chain, always measuring it at the same point,
midway between the sprockets, as shown in the photo at right.
3. Inspect the drive chain for:
• damaged rollers
• dry or rusted links
•
excessive wear
• improper adjustments
Replace the drive chain (page 65) if it has damaged rollers, loose pins, or
kinks that cannot be freed. Lubricate any kinked or binding links and
work them free. Adjust chain slack if needed.
4. Inspect the front motor sprocket and rear wheel sprocket teeth for
excessive wear or damage. If necessary, have your BRAMMO Authorized
Service Agent replace a worn sprocket.
Servicing Your Enertia 63
1” to 1 1” to 1--3/8” 3/8”
(25mm to 35mm) (25mm to 35mm)
A 124 Link - 420 Standard Roller Chain connects the motor’s 13 tooth sprocket to the rear wheel’s 64 tooth sprocket.
The service life of the chain depends on proper lubrication and adjustment. Poor maintenance can cause premature wear or damage to the drive chain or
sprockets. The drive chain should be checked, adjusted, and lubricated as part of the pre-ride inspection (page 27). Under severe usage, or when the
Enertia is ridden in unusually dusty or muddy areas, more frequent maintenance will be necessary.
Before servicing your drive chain, turn the ignition switch to the OFF position, and lower the kickstand. It is not necessary to remove or replace the drive
chain to perform the recommended service in the Maintenance Schedule.
