Needle bearing d.16x21x17.5mm silver Yamaha DT 125 Italkit

Reinforced silver Needle bearing from manufacturer Italkit for Yamaha DT 125.

When the needle bearing operates with excessive play or wear, metallic noises may appear in the upper part of the engine, along with abnormal vibrations or premature wear on the gudgeon pin and the small end of the connecting rod.

A reinforced Italkit needle bearing in good condition allows the piston pin to operate correctly, with lower friction and more even support of the needles. It is a recommended part when replacing the piston, removing the cylinder, or carrying out internal engine maintenance, as reusing a marked bearing can compromise the reliability of the assembly.

The reinforced silver finish is designed to withstand higher RPM ranges and more demanding use than a standard bearing.

This needle bearing has dimensions of 16x21x17.5 mm, with an inner diameter of 16 mm, an outer diameter of 21 mm, and a height of 17.50 mm. It corresponds to KV bearing type and is compatible with the Yamaha OEM reference 93310316B400.

With a size of 16x21x17.5 mm, it is a suitable option for Yamaha DT 125 performance builds and maintenance where the aim is to reinforce the connection between the piston, gudgeon pin, and small end of the connecting rod.
