Description

Fine-tune your chain length with the Universal Parts #428 Offset Half Link. Also called a half link, this component lets you adjust chain length by a single pitch instead of the standard two — the perfect solution when your chain adjusters are maxed out or your drive base is fixed. Built from treated high-tensile steel with an ultimate tensile strength of 18.0 kN (4,091 lbs), it's a reliable fit for dirt bikes, ATVs, go-karts, mini-bikes, and pocket bikes running a #428 pitch chain.

  • Pitch: 12.70mm
  • Roller diameter: 8.51mm
  • Pin diameter: 4.45mm
  • Width between inner plates: 7.75mm
  • Pin length: 16.70mm (L) / 18.2mm (Lc)
  • Inner plate depth: 11.80mm
  • Plate thickness: 1.60mm
  • Ultimate tensile strength: 18.0 kN / 4,091 lbs
  • Average tensile strength: 20.1 kN
  • Weight per meter: 0.70 kg/m

Compatible Applications:

  • Dirt bikes & pit bikes — 110cc, 125cc, 150cc (Chinese and Japanese models)
  • ATVs & quads using #428 final drive
  • Go-karts — Trailmaster, Hammerhead, and custom predator-engine builds
  • Mini-motos, pocket bikes, and small-bore street-legal bikes

Installation note: Always seat the cotter pin or clip fully and orient it facing away from the direction of travel.
