Review on Vertex 23547A High Compression Piston by Damon Mertz

Revainrating 5 out of 5

Don't be disappointed!

This piston is very well made. I installed it on my 2004 Yamaha XG250 Tricker which is the base for a 2008 Raptor. I had to fit a Raptor crank as the thinner handle crank didn't fit this piston (small end). cool change! I tried JE 12:1 but it worked and Wiseco 10.5:1 was good too but I got a bit more MC Gusto off the top and it was my first time using this company. completely satisfied!
