Product Description
Detailed Specifications & Features

GN125 Motorcycle Sprocket & Chain Kit — 428H O-Ring Drive Set

Complete bolt-on drive kit for Suzuki GN125 / GN125H commuter motorcycles. The kit pairs a 15T front sprocket and a 45T rear sprocket with a 428H O-Ring sealed chain, so the whole drive line is replaced in one job and wears in together instead of fighting an old chain.

Why riders and workshops choose this kit

  • O-Ring sealed 428H chain — factory-loaded grease stays inside the rollers, cutting chain stretch and lubrication intervals on dusty or rainy roads.
  • Hardened 45# carbon steel sprockets — through-hardened teeth and induction-hardened surface resist hooking and keep the original 15T / 45T ratio.
  • Matched ratio, no guesswork — front, rear and chain length are pre-checked for the GN125 swingarm, so no link removal is needed on a stock bike.
  • Zinc-plated finish — salt-spray tested plating keeps the sprockets and side plates from rusting between services.

Application notes

Recommended for daily commuting, courier fleets and rental bikes running 125cc four-stroke single engines. Replace the sprockets and chain as a set — a new chain on worn teeth will stretch again within a few thousand kilometres.

Packing and ordering

Each kit is packed in a branded colour box with the chain coiled, sprockets bagged and a master link in a separate sleeve, then 10 kits per export carton.
