Here is the piston ring ATHENA 480cc Ø98mm mounted on YAMAHA YZF 450cc and YAMAHA WRF 450cc. This ring is mounted on the dimension A, B, ... of your piston. Ideal to overcome a loss of compression or tightening. If you have a strong loss of compressions we advise you to change the piston for the dimension above. Do not forget to change your seals for a tight reassembly and therefore increased reliability.
