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.
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.
