Whether you're replacing a worn-out OEM setup or upgrading for more precise power delivery, the Vortex Chain and Sprocket Kit offers enhanced performance, weight savings, and customization options for your motorcycle.

Key Advantages Over OEM Kits:

• Lighter Weight: Choose an aluminum rear sprocket for reduced rotational mass and improved throttle response, or go for steel for extended durability. Vortex kits offer weight optimization that OEM kits typically can’t match.

• Custom Options: Select your preferred chain color (gold or black), sprocket material (aluminum or steel), and tooth count for both front and rear sprockets—something not available with factory kits.

• Better Throttle Response: Thanks to reduced unsprung weight, the Vortex setup delivers a sharper, sportier feel—ideal for spirited riding or track days—unlike the more conservative feel of OEM gearing.

• Longevity by Choice: Aluminum options prioritize performance, while steel versions extend lifespan. OEM sprockets often lean toward general use, lacking specialized choices.

• Wider Compatibility: Available for a large range of motorcycles, Vortex kits provide flexibility to upgrade or tune your drivetrain to fit your exact riding style.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
