Description
WORLD FAMOUS EDR R1 Crankshaft/Crankcase HD Stud kit!
EDR Performance is the worlds ONLY shop that has a complete main bearing and crankcase stud bolt kit for the 2015+ R1/R1M/R1S contains over 50 pcs. This kit has been used around the world in many top level racing organizations, often times by TOP teams though they cannot advertise this.
We found the 2015+ R1 suffers from multiple design flaws; super long crankshaft, extremely thin cases/support, cross drilled oil feed from the end of the crank not the cases like most bikes. Add this all up and the fact they spin to well over 14,000 rpm and you can see why the cranks can "flex" and snap! We have seen and talked to well over 100 2015+ R1 owners that have suffered from the failures. Our stud kit came after years of development and as a solution to increase the durability and reliability of the engine! We have yet to hear of any crank failure in a R1 with our stud kit to date!
