PASS: IN FACTORY SPEC(30 mm / 1.18 in)

FACTORY TOLERANCE CERTIFIED: Chain tension is in optimal balance. Allows complete swingarm articulation through the entire suspension stroke without countershaft binding or excessive snatch on deceleration.

Precision Alignment

Rear Axle Caliper Alignment

Why mechanics never trust swingarm stamped notches: Factory stamping tolerances can be off by up to 3mm, causing the rear tire to "dog-track" and chew through tire shoulders.

PERFECT WHEEL ALIGNMENT (PASS)Δ 0.0 mm

Rear axle is square to the swingarm pivot within 0.5mm. Sprocket and chain tracking run in direct true plane.

Wear Limit Diagnostic

21-Pin (20-Pitch) Chain Stretch Test

Pull chain tight and measure distance across 21 consecutive pins with a vernier caliper. Standard new length = 317.5 mm; factory discard limit = 323.0 mm (1.5% stretch).

Three Professional Workshop Alignment Techniques

Method 1 — Swingarm Pivot to Axle Center (The Gold Standard):

Insert a precision rod or vernier caliper measuring from the center dimple of the swingarm pivot bolt to the center dimple of the rear axle on both left and right sides. Both sides must match within 0.5 mm. This mechanically guarantees that the rear axle is perfectly perpendicular to the motorcycle chassis centerline regardless of factory swingarm stamping defects.

Six-Step Workshop Chain Adjustment Protocol

Rear Axle Nut: Not Available - Refer to Factory Workshop ManualAdjuster Locknut: 16 - 22 N·m

1Loosen Axle Spindle Nut

Loosen the rear axle nut 1 to 2 full turns (Not Available - Refer to Factory Workshop Manual). Keep it snug enough so the wheel does not cock sideways freely.

2Back Off Adjuster Locknuts

Back off the jam locknuts on both the left and right adjuster bolts by 2 to 3 turns using a 12mm or 14mm box wrench.

3Turn Adjusters in Small Increments

Turn both adjuster bolts equally. One full 360° turn of an M8 bolt moves the axle by 1.25 mm. Adjust 1/4-turn at a time.

4Kick Tire Firmly Forward

Kick the rear tire firmly toward the front of the motorcycle to ensure the axle blocks are solidly seated against the bolt heads.

5Torque Rear Axle Nut to Spec

Torque the axle spindle nut to exactly Not Available - Refer to Factory Workshop Manual. Always use a calibrated 1/2" torque wrench.

6Crucial Re-Check of Slack

Torquing down the rear axle nut frequently tightens chain slack by 2 to 4 mm! Always re-check slack after full torque is applied.

NHTSA #21V361000EXTERIOR LIGHTING:TURN SIGNAL

Received: 01/01/2021▼

Defect Description

Ducati North America (Ducati) is recalling certain 2021 Scrambler 800 Night Shift motorcycles. The front and rear turn signal lights may not flash brightly enough. As such, these motorcycles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Safety Hazard / Consequence

Turn signal lights that aren't bright enough can reduce other driver's ability to see that the turn signals have been activated, increasing the risk of a crash.

Factory Remedy & Repair Action

Dealers will replace the front and rear turn signals, free of charge. Owner notification letters were mailed on June 28, 2021. Owners may contact Ducati customer service at 1-888-391-5446. Ducati's number for this recall is SRV-RCL-21-009.

Manufacturer Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
