Made with highest quality aluminum

• 7075 T6 aluminum is the best grade material for light weight and durability
• The weight you save on drive components is multiplied as rotating mass
• Less rotating weight improves acceleration

CNC Machined to tightest tolerances

• Our unique manufacturing process creates a perfectly concentric sprocket every time
• This frees horsepower and extends the life of both chain and sprocket
• Perfected tooth design has less drag and reduces friction for better acceleration and deceleration

Attractive, Smart Design

• Vortex patented design offers a unique look
• Standard sprockets have a bright, polished look; clear anodizing helps prevent corrosion
• Mud grooves and coatings help keep components clean
• All sprockets available in single tooth increments

NOTE:CAT5 sprockets are custom made and not eligible for return. If you are uncertain whether this is the correct sprocket for your application, please contact us, and a sales associate will double check your order selection to make sure you've selected the correct item. Thank you for your business.

Changing Gearing

• Adjusting the tooth count in front and rear sprocket changes the way the bike performs.
• A size increase in the rear sprocket and/or a decrease in the front sprocket will favor torque for increased acceleration.
• A size decrease in the rear sprocket and/or an increase in the front sprocket will favor top end speed.

Gearing is a key variable in racing. Each rider, bike, and track will demand a different set-up. Though we cannot tell you which will work best for you, the most popular combination for a typical track-day would be a +2 Rear / -1 Front for increaseacceleration without limiting too much top end speed.

Weight Reduction Changing the sprocket to the Vortex aluminum rear sprocket and lightened front sprocket will eliminate considerable mass. This can be further reduced by converting chain and sprockets to a 520 size.
