2012 Beta 350 RS SM Dirt Bike Torque Specs
Shop parts for a 2012 Beta 350 RS SM Dirt Bike.
The 2012 Beta 350 RS SM is a dedicated supermoto built on the 350cc four-stroke platform with 17-inch supermoto wheels, sticky road tires, inverted fork with supermoto-specific valving, and aggressive braking components. The 349cc liquid-cooled DOHC four-valve single with electronic fuel injection and six-speed gearbox delivers the broad, forgiving powerband through a chassis tuned for the unique demands of supermoto riding — tight asphalt corners, hard braking zones, and occasional dirt sections. The steel perimeter frame handles the mixed-surface forces that supermoto generates: aggressive pavement cornering loads, hard braking from high speeds, and abrupt transitions between tarmac and loose dirt.

Wheels & Drivetrain
| Fastener | Torque (Nm) | Torque (ft-lbs) |
|---|---|---|
| Front Axle Nut | 50 | 37 |
| Rear Axle Nut | 100 | 74 |
| Front Sprocket Bolt | 50 | 37 |
| Rear Sprocket Nuts | 30 | 22 |
| Chain Adjuster Lock Nuts | 18 | 13 |
Brakes
Supermoto braking generates the highest peak brake loads of any Beta application. Aggressive deceleration from high corner-entry speeds loads the front caliper and disc mounting hardware harder than enduro or road-sport use.
| Fastener | Torque (Nm) | Torque (ft-lbs) |
|---|---|---|
| Front Caliper Bolts | 30 | 22 |
| Rear Caliper Bolts | 25 | 18 |
| Front Disc Bolts | 10 | 7 |
| Rear Disc Bolts | 10 | 7 |
| Front Master Cylinder Clamp | 10 | 7 |
| Rear Master Cylinder Mount | 10 | 7 |
Dry vs. Wet Torque
Oil drain plug: always wet; reduce 15–20% with sealant. All other values assume dry threads.
Supermoto Loading Patterns
Supermoto riding combines the hardest braking of pavement racing with the abrupt surface transitions of off-road. The 350 RS SM’s chassis absorbs lateral cornering loads on sticky tires, violent weight transfers under braking, and sudden traction changes at tarmac-to-dirt transitions. Axle nuts, caliper bolts, and disc bolts see more intense cycling than on any other Beta application. Post-session torque verification of brake and axle hardware should be standard practice for the supermoto platform.
Thread Locker Recommendations
