Ninja 300 Garage: 15T Front-Sprocket Install and Test-Ride! I go through the removal of the stock 14-tooth sprocket, installation of the 15T sprocket and then take a test-ride to check both my fitment/alignment of the rear-wheel, chain-slack and of course, the sprocket!
As-always, I cover details along the way with various tips, caveats, and stuff that's good to know before you try this installation!
The verdict on the 15T sprocket? Watch and see! :)
*NOTE: Months after doing this video, I decided to add a 43T sprocket to the rear of my bike. I am much happier with this arrangement, but I had to add a 108-link chain to do it, cut down from 120 links. The stock chain is 106-links.
What I recommend as an alternative is to simply go with a 40t rear, but leave the stock 14t sprocket as-is. This will result in a really nice final-drive ratio and you can re-use the stock 106-link chain.
If you've already installed the 15 and don't want to mess with it, you can add a 43 aluminum sprocket to the rear. This saves about 1 lb. of unsprung weight and looks good, but you will need a bigger chain.
Right now, I have a 15t/43t setup and it's fantastic, and it results in an accurate speedo, but you can also get there just by going with a 14/40 setup. I have way more accessible-power all of the rev-range, with a 103mph top speed. Acceleration from 70+ is much better than a 15t/42 setup.
Sorry if this is confusing.
