Function-Formed™ Transmission Side Cover

The Function-Formed transmission side cover provides a minimalist, durable aluminum option for Harley owners, though some riders may prefer competitors with more customization and a lower price.

This transmission cover looks awesome on my bike and was easy to install, I'm very happy with how it performs.

After using this transmission side cover for a few weeks, I'm really impressed with its quality, durability, and easy installation - it's a great upgrade that looks awesome and protects my transmission.

After installing my new transmission side cover a few weeks ago, I'm thrilled with the quality, performance, and looks - the minimalist CNC aluminum design fits perfectly and looks fantastic, the side fill port makes checking fluid easy, the heavy duty mounting hardware ensures a reliable fit, and the durable finish has held up great so far against road debris and weather - with its precise manufacturing and great aesthetics, even though it's not cheap, I feel it provides excellent value and is a great upgrade for my Big Twin.

This transmission side cover looks great on my bike and has held up well over hundreds of miles of riding.

This transmission cover looks slick but ran my bike hotter than expected. I'd only recommend it for expert mechanics, not casual riders.
