Piston Kit Gp Domed 54.0 a RS125 03-09, Vertex 23105A Gp Honda

VERTEX UK PISTON KIT FORGED 23105A 1-RING

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.
