What is RM Cash
Chris in WA
seems to be a great looking product but unfortunately a little too thick. fits well on the stock pipe but no the procircuit.
Klint in Somersby
High tension springs easy to install. Looks like the will last.
David in MD
plug fits well and does its job for the price, but its a harder rubber than fmf
Alex in VA
Fits the pro circuit platinum expansion chamber on my 02 CR250 perfect. More tension than the stock springs and a better seal.
