Worked Great!

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    It's well made, but not for 78mm bore
  

*by E***N on Reviewed in the United States on February 14, 2022*

It's wiseco, it's decent and well packaged but it's not for the 04-07 cr250r. The later models after 07 may work bc they had a slightly smaller piston but the 04 to 07 have a 78mm bore. The piston should be around 77.96 to 77.98mm this one is 77.45mm. I actually ordered 2 of them and got the same measurements so it wasn't a fluke.
