DID | 428 HD (pitch 1/2 x 5/16 inch)

The DID 428 HD chain is the ideal choice for demanding motorcyclists and impresses with its high-quality workmanship and technical advancement. As a renowned original equipment manufacturer for numerous leading motorcycle brands in Japan and Europe, DID stands for quality and reliability. International racing teams also rely on the outstanding technology.

Chain specifications:

• Standard version: Open with clip lock (solid rivet lock optionally available)
• Seal: No seal
• Colour: Steel colour

The 428 HD is a consistent further development of the proven 428H. Instead of the classic winding technique used in roller production, DID relies on a modern production process from solid round material. This avoids weak points caused by seams and leads to a significantly more robust and durable chain.

Compared to the standard DID 428D chain, the 428 HD offers a reinforced design with thicker inner and outer plates, which results in a noticeably higher tensile strength. Thanks to its low weight, it is perfectly suited for motorcycles with an engine size of up to 125 ccm.
