Enduro Maintenance Checklist
Stark Varg EX Maintenance Checklist
The Stark Varg EX is the enduro version of Stark's electric dirt bike, with lights, turn signals, a horn and mirrors. This checklist covers what to do before and after every ride and the service intervals from Stark's 2025 VARG EX owner's manual.
Key Intervals At A Glance
- Every ride: grease the chain and docking station release before and after riding, bleed the forks after every ride.
- Fork oil: every 15 riding hours or 12 months, whichever comes first.
- Fork and shock service, gear oil: every 40 riding hours or 12 months.
- Brake fluid and coolant: every 12 months.
- Battery storage: keep at 30 to 50 percent charge and check every two weeks.
How The Stark Schedule Works
Stark's manual has two parts. The first is a before and after every ride checklist grouped by system: electronics, brakes, frame, suspension, battery, cooling, transmission and wheels. The second is a service interval table based on riding hours and months. Items marked with an asterisk are done at whichever comes first and are performed by a workshop.
There is no engine oil, air filter, spark plug or top end on an electric bike. What is left is the drivetrain, suspension, brakes, cooling and battery care, and the suspension intervals are some of the shortest on the bike.

Ownership Notes
What is different on the EX: the service interval table in the 2025 EX manual is the same as the MX. The differences are the street and trail equipment. The manual lists lights, turn signals, horn and mirrors, and it notes that the bike is no longer road legal if the Stark phone is removed. The maintenance tables do not add separate checks for that equipment, so add a quick lights, signals, horn and mirrors check to your pre-ride routine if you ride on the road.
Battery care: charge if below 20 percent before a ride, and store at 30 to 50 percent charge, checking every two weeks.
Enduro use: long days in mud and water are the harsh conditions that justify doing workshop items early. Fork oil every 15 riding hours is the first interval most EX riders will hit.
