GAS GAS MC-E5 Torque Specifications (2021): Electric Youth MX Fastener Reference
Shop parts for a 2021 GAS-GAS MC_E5 Dirt Bike.
The 2021 GAS GAS MC-E5 is one of GAS GAS’s early electric youth motocross offerings—a machine that brings the excitement of MX competition to young riders through an electric powertrain. The MC-E5’s electric motor provides smooth, controllable power suited to beginner and intermediate youth riders, and its design eliminates the premix and top-end service requirements of a traditional two-stroke. Maintenance focus shifts entirely to the chassis, drivetrain, brakes, and electrical system hardware.
Here are the torque specifications for the 2021 GAS GAS MC-E5.
Electrical System & Motor Mounting
Motor and battery mounting hardware on the MC-E5 must be checked regularly. Vibration from MX use can work loose connections over time on an electric youth machine. Always disconnect the main battery before servicing any electrical components on the MC-E5.
| Component | Torque Spec |
|---|---|
| Motor mounting bolts | 18–22 Nm (13–16 ft-lb) |
| Battery pack mounting bolts | 10–12 Nm (7–9 ft-lb) |
| Controller housing fasteners | 4–6 Nm (3–4 ft-lb) |
The MC-E5 is a youth machine—never exceed specified torque on plastic or composite housing fasteners. Over-torquing small housing fasteners can crack the housing and compromise weatherproofing around the electronics.
Drivetrain & Wheels
Electric drivetrain on the 2021 MC-E5 provides immediate, smooth power delivery. The electric power character means no sudden clutch-engagement spike loads on the drivetrain, but pre-ride axle nut and chain/belt drive fastener checks are still important before every session.
| Fastener | Torque Spec |
|---|---|
| Front axle nut | 15–20 Nm (11–15 ft-lb) |
| Rear axle nut | 30–35 Nm (22–26 ft-lb) |
| Drive sprocket/pulley bolts | 10–12 Nm (7–9 ft-lb) |
| Drive adjuster lock nuts | 5–7 Nm (4–5 ft-lb) |
Suspension & Chassis
Youth-scale suspension components on the 2021 MC-E5 use small fasteners with low torque values. A low-range wrench is essential for accurate fastener service on this youth electric machine.
| Fastener | Torque Spec |
|---|---|
| Fork clamp bolts | 8–10 Nm (6–7 ft-lb) |
| Handlebar clamp bolts | 8–10 Nm (6–7 ft-lb) |
| Swingarm pivot bolt | 22–26 Nm (16–19 ft-lb) |
| Rear shock mounting bolts | 18–22 Nm (13–16 ft-lb) |
| Subframe bolts | 8–10 Nm (6–7 ft-lb) |
Brakes
Disc brake hardware on the 2021 MC-E5 is youth-scale. Thread locker on disc bolts is recommended even on electric youth bikes where high-frequency vibration from the two-stroke is absent—the MX terrain itself generates enough vibration to loosen unprotected small fasteners.
| Fastener | Torque Spec |
|---|---|
| Front caliper mounting bolts | 10–12 Nm (7–9 ft-lb) |
| Rear caliper mounting bolts | 8–10 Nm (6–7 ft-lb) |
| Brake disc bolts | 5–6 Nm (4–5 ft-lb) |
A low-range beam or digital torque wrench (3–30 Nm) is the appropriate tool for all fasteners on the 2021 GAS GAS MC-E5. Always disconnect the battery before any electrical system service, and build pre-ride fastener checks into the routine for every session with this youth electric machine.
