PISTON KIT GP DOMED 54.0 B RS125 03-09, VERTEX 23105B GP HONDA

Vertex "kit " DOME TOP piston for the Honda RS 125

These are a good alternative to the Standard HRC pistons at a much better price

Piston kit comes with .8mm flat ring Ring , Pin , and 2 x clips

Its very important to prep them well , by champhering all the skirts ,and the ring groove ,as well as setting the ring gap , as the ring fits all sizes ( IE the biggest )

Ring gap is at the back , so runs over the rear boost port , requiring good champhering of the rear port .

I recommend the ring is changed half way through the 300 to 350 KM life of the piston , to prevent the ring locating tag breaking.
