What is the difference between Plain Carbon Fiber vs Twill Carbon Fiber weave?

With carbon fiber gaining even more popularity than before, the difference between to the 2 most popular weaves is something every rider needs to understand. Every carbon fiber part has its own special number of layers of fibers to create the best ratio of strength, weight and stiffness.

"Plain" Carbon Fiber Weave

While there certainly is nothing "plain" about carbon fiber motorcycle accessories, this 1x1 checkerboard weave type is referred to as "plain weave". Plain weave fabric is the second most commonly used of all carbon fiber patterns. The plain weave creates a grid-like pattern. Plain weave is a slightly tighter weave pattern than twill. Plain weave has a smaller and tighter looking pattern and generally more subtle in appearance. You really have to get up close to notice a plain weave. Structurally, there is a marginal difference between plain vs twill.

"Twill" Carbon Fiber Weave

Sometimes referred to as 2x2 weave, the twill weave is actually the most common weave type for carbon fiber parts. This pattern goes over two intersecting warps and then under two (hence 2/2) to create a woven fabric with a diagonal pattern to it. 

What carbon fiber weave is best for my motorcycle?

Structurally, there is a marginal difference between the two, so choose which looks best to you. It really boils down to personal preference and what your bike manufacturer uses for any stock carbon pieces that come on the bike. Although it is somewhat common to mix different carbon weaves, the best look is obtained when all the carbon fiber parts on your motorcycle shares the same weave.
