Motorcycles are relatively basic machines which makes them easy to upgrade for performance. I’m not doing anything nearly as cool as Rob with his Ducati 998, but just a couple basic performance upgrades on a sportbike. I finally wore out the original chain on my 2005 CBR 600RR at 23k miles, so it was a good time to upgrade the chain and sprockets for a bit more acceleration.
There are two ways to improve acceleration when doing a chain and sprockets upgrade: gearing and mass reduction. I bought this quick acceleration kit which consists of a 15-tooth front sprocket compared to the stock 16-tooth, and a thinner/lighter 520 size chain versus the stock 525. You can get aluminum sprockets for increased mass reduction, but I decided to go with steel for better longevity.
To get to the front sprocket, you need to remove the shift linkage first.
I marked the alignment of the linkage to the shaft before taking the linkage off.
There is a lot of gunk hiding under the cover.
And even more hiding after the sprocket comes off.
