Chain Tension Go/No-Go Tool – 58–61mm Gauge for KTM, Husqvarna & GasGas (2023–2026)

Set your chain tension quickly, accurately, and consistently with this purpose-built go/no-go gauge. Designed to sit directly on the swingarm chain guard and under the chain, this tool removes the guesswork from adjustment and delivers repeatable results every time.

Simply place the tool on the chain guard, tighten your adjusters until the chain contacts the gauge, lock down the axle, and remove. No measuring, no second-guessing—just consistent, correct tension.

What sets this tool apart is its profiled fit. It matches the chain guard shape, allowing it to stay stable and in place during adjustment—making it a true hands-free solution compared to traditional methods.

Key Features:

• Go/No-Go Precision: Dual-sided gauge with 58mm minimum and 61mm maximum (2.28"–2.40")
• Hands-Free Setup: Leave in place while adjusting chain tension—no rechecking required
• Profiled Fit: Designed to sit securely on the swingarm chain guard
• High Visibility: Printed in bright orange for easy use in shop or track conditions
