Chain Tensioner 101 OCTANE (Manufacturer's reference: 43010-RT)

Replace or improve the chain adjustment of your moped with this anodised aluminium chain tensioner, supplied in pairs. Designed to fit a 12 mm rear axle, it offers precise tension adjustment and a neat appearance thanks to its red finish. Ideal for restorations, custom builds, and regular maintenance of small urban vehicles, lightweight roadsters, or utility trikes.

• Material: anodised aluminium (red finish)
• Packaging: pack of 2 (pair)
• Total length: 75 mm
• Hole diameter: 12.5 mm (designed for axle Ø 12 mm)
• Thread: M6 — thread length 40 mm

This tensioner naturally fits classic moped models — for example, SIMSON SD 50, PUCH MAXI 25, or SIMSON S51 — but be sure to check the dimensions of your axle before ordering. Compact and lightweight, it easily replaces original tensioners to restore a clean chain alignment and facilitate tensioning during adjustments.
