I'm looking to increase acceleration by raising gear ratio, and thinking something like a 42 rear (165 pound rider).
Somewhere I saw something about front sprocket size and the load it places on the engine and the drivetrain, and can't find it anywhere. I could replace the front sprocket with a 16 to accomplish the same thing.
So what is the best to replace and for what reasons, front or rear sprocket? I have to have the rear off for a new chain, so that isn't a factor.
And as an aside, why is the 2008 Busa going to an 18/43 sprocket combo? What would be the advantages?
P.S.- Just for reference-
