Installed this gasket kit on my TRX250. The fit was precise and the quality of the materials is excellent. It runs perfectly with no leaks. A great value for the price.
This gasket kit matches the OEM specs perfectly. The materials are top notch and it installed without any problems. A reliable part that performs just as it should. Very satisfied with the purchase.
The piston rings seat perfectly! No more smoke or oil consumption issues.
Secure packaging with no crushed edges. The kit contains all necessary seals for my 2020 EX rebuild. Very pleased!
Complete solution for my rebuild project. The piston pin fits snugly with no play. Engine runs cooler too.
