Despite all the power, the final drive is still way too tall.
I need to confirm that the chain is 525 and is the same sprockets as the previous models.
The stock chain for the 1100 is a 525, rear sprocket other than the teeth count is the same, not sure about the front sprocket on the Evo, but I'd guess it the same. Aloha Alex
