Vertex "kit " FLAT TOP piston for the Honda RS 125 / RS250
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
They are available in the following sizes ; ( please specify when ordering )
A 53.94
B 53.95
C 53.96
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
