The Pro Twin Performance Custom Engine Designer program is an innovative way for us to help you make sure you choose a build that's perfect for you. It's quite simple.

STEP 1 - Choose your model
This is important because different compression ratios and displacements react differently to the weight of the motorcycle and typical riding style.

STEP 2 - Choose your build category
Everyone uses their bike differently, lives in different areas, has access to different octane fuels, and has different expectations for their builds. This is a very important step in the process so read throughly.

STEP 3 - Choose your engine size
This has much to do with your current engine format (crankshaft stroke), budget, and desired performance gain.
