About us

MJK Performance is located in Calgary, Alberta. It is a family owned business which is operated by us, Dale Yamada and Michelle Martin. We started the company (Mad Jap Kustoms Inc which is doing business as MJK Performance) in 2007 and have been in our current location since 2012. We rebranded our company Mad Jap Kustoms Inc in February 2017 to MJK Performance as we felt it better represented the direction the company was going in designing and CNC machining a new product line of Bagger, FXR and Dyna parts.

We pride ourselves on exceptional customer service and believe our customers deserve the highest quality and craftsmanship in everything we do. 

We are excited to offer our new line up of high quality, precision CNC machined motorcycle parts to our customers. We know that if you purchase our product you will see the difference quality makes!

Thanks for shopping with us and supporting a small business!
