    I was told that the KTM 50 piston is a direct swap for the husky Boy 50, does anyone know if this is true, & if it is...what year and model of KTM swaps ????
    thanks

    Depends on the Year of both the Husky & KTM. Somewhere around 2000? KTM started using the Beta engine. Husky started using the Morini S6 engine in their liquid cooled SR. in 02.
    Does your Husky Boy have the Morini S5 or S6 engine?
    You can get a NOS piston off ebay for a lot less than a KTM dealer who would most likely have to order it in anyway. Or .......
    I might have some spare engine parts for sale for both the S5 & S6 engine.
