Chain Sizing & Swingarm Slack

Recommended Drive Chain Length:108 Links

Fits within factory swingarm axle slot adjustment range (30 - 35 mm (1.2 - 1.4 in) on side stand). Retain stock 108 links.

Factory Swingarm Slack Tolerance

30 - 35 mm (1.2 - 1.4 in) on side stand

Measure slack at midpoint between countershaft and rear axle on the bottom strand with the motorcycle on its side stand unladen.

Master Link Requirement:Rivet link (ZJ) mandatory for > 400cc

Factory Swingarm Slack Tolerance

30 - 35 mm (1.2 - 1.4 in) on side stand

Test Condition: Measure midway on lower chain run with bike on side stand (unweighted).

Measured Chain Slack

33 mm

10mm (Too Tight)Factory Window: 30 - 35 mm65mm (Critical Slack)

PASS: IN FACTORY SPEC(33 mm / 1.30 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.

LEFT PIVOT TO AXLE:

215.0 mm

RIGHT PIVOT TO AXLE:

215.0 mm

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).

MEASURED 21-PIN DISTANCE:

317.5 mm

Stretch: +0.0 mm (0.0%)

Remaining Chain Pin/Bushing Life:100% (GOOD)

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.
