Honda CBR1000RR (06-19) 44 Tooth 520 Conversion Sprocket

Toce Performance has teamed up with the Engineers at Dirt Tricks and a few other industry leaders to be able to finally launch some of the lightest and strongest sprocket kits on the market. Made from Chromoly steel rather than aluminum or stainless makes these rear sprockets at least 2.5x stronger than other units out there.

Machined with to the tightest industry standards and tolerances, Zirconium plated and laser etched designs allows us to offer a 2 year wear guarantee with a free replacement due to defects in materials, craftsmanship, and excessive wear.  

Sprockets are only offered in 44 at the moment but will be available in different tooth sizes to accommodate your desired performance.  Please be mindful of your gearing configuration when upgrading to a 44 tooth.. 
Toce will not swap out sprockets due to failure to order the correct configuration for your bike.

06-16 CBR1000 Factory is 42

17-19 CBR1000 Factory is 43

Units may have a 3-5 day handling time during initial launch.

We will be adding new applications weekly. Custom Configurations available 

Please Note: These are not stock width sprockets, they are for 520 chains and front sprockets, which are available as kits in our main menu.

PLEASE ENTER THE SPECIFIC YEAR AND MODEL OF YOUR BIKE IN THE ORDER COMMENTS SECTION DURING CHECKOUT.

All the Technical Stuff
You can view a picture of the von Mises yield criterion stress analysis below
The finite element stress test analysis for 9000 pounds of chain tension (100 link 1100cc chain max tensile strength) results in a maximum stress level of 170,000psi
Our material's yield strength is 230,000psi. Meaning the chain would have to handle 30% more pressure per square inch prior to any deformity of the sprocket. 
Tensile strength of the sprockets are 255,000. Catastrophic failure point is this margin...
