This shows a detailed-installation of a new 43-tooth rear sprocket for the Ninja 300 (ZX-3R) along with a D.I.D. rear-chain along with usage of a chain breaker/riveter tool.
Afterward, I do a quick test-ride to see how the 43t rear sprocket positively-affected the gearing!
IMPORTANT! I went with the 43t sprocket because I had already installed the +1 (15-tooth) in front. You can get the same final-drive ratio with the stock 14t CS sprocket by simply going with a 40-tooth rear sprocket (stock is 42t)—and this will also work with the stock chain. Normally, you should change your chain when you change sprockets (depending on wear), and I wanted to both learn and teach how to remove and install a chain for the purposes of the video anyway.
I only recommend the 43t in back if you already installed the 15t CS sprocket, are in the market for a new chain (for any reason) and simply want to improve things with a 43t rear-sprocket.
The stock sprocket is 28.8 ounces, almost 2 lbs.!
The Vortex sprocket is 14.4 ounces. Huge weight savings, great for reducing unsprung weight!
Special thanks to member Ninja300Stealth for doing the legwork on the 43t rear-sprocket.
