Chain kit standard
for Model: Yamaha RD 125 DX 1975-1977
Here you get the chain set in the standard version, i.e. sprocket, chain wheel and chain in the ratio as it was originally delivered.
In our configurator you can select the sprocket and the chain wheel if you wish, the chain length is calculated on the basis of the selected sprocket or chain wheel.
Conversion Chainset Configurator
Here you can get a Conversion Chainset with the original gear ratio.
In our configurator you can select the sprocket and the sprocket wheel, if desired. The chain length is calculated on the basis of the selected sprocket and the sprocket wheel.
It is possible that an exact match of the selected gear ratio with the chain is not possible and the chain may have to be shortened, but you will never get a chain that is too short.
The conversion kit deviates from the original chain kit pitch, which is very popular, for example, for race track use.
A chain with a higher tensile load is always used as the standard chain in the conversion kit, as a (smaller) chain is usually used here.

D.I.D Standard Chain 428HD/110 with clip lock
DID is an original equipment manufacturer for many Japanese and European brands. Leading racing teams in
road and off-road sports rely on DID technology.
As a successor to the proven 428H, the 428HD uses a new technology for manufacturing the rollers. Previously, the rollers were wound from sheet metal strips, which created a seam and thus a weak point. With the new technology, the rollers are made of round material, thus avoiding a seam.
Compared to the standard 428D chain, the 428HD is reinforced by thicker link plates and therefore has a significantly higher tensile strength.
- 20-50% higher wear resistance compared to the DID 428HD
- reinforced design
Technical data:
428 pitch / 110 links / running index 150.
tensile strength 2390kg / with clip lock
Scope of delivery:
1 x D.I.D.standard chain
