<p>Vetex piston kit for the Aprilia RS 125 1988-2012 both Rotax 122 And 123 Type Motors</p>
<p>Choose Piston Size 53,93 - 54,00.</p>
<p><strong>Important:</strong></p>
<p>Vertex <strong>recommends a tolerance of 0.07 mm</strong> for this piston.<br /><br />Example: cylinders with size 54,02 the appropriate piston would be 53,95.<br /><br />It is very important to take into account this consideration since they do not have the same tolerance as the Vertex 2 rings pistons for which 0,05 mm is recommended.<br /><br /><strong>The needle cage must be replaced with the piston.</strong></p>
