Installing a larger rear sprocket will make 1st gear seem more stronger and more powerful, will give you more acceleration, but you'll need to shift into 2nd gear sooner to keep the engive from revving. If you do mostly trail riding, a lreager rear sprocket will give you more power to climb steep hills.Mar 03, 2010 · Mar 3, 2010. b3av3r said: and realize that it is going to give you the speed/rpm/gear even if that speed isn't realistic. it is just using the math to generate the numbers. so don't get pissed when the calculator says you can do 212 in 6th at redline, cause it ain't happening. no this one just says i can do 360+ and 212 in first gear. In our example, dividing the 30 teeth of the driven gear by the 20 teeth of the drive gear gets us 30/20 = 1.5.We can also write this as 3/2 or 1.5 : 1, etc.; What this gear ratio means is that the smaller driver gear must turn one and a half times to get the larger driven gear to make one complete turn. In our example, dividing the 30 teeth of the driven gear by the 20 teeth of the drive gear gets us 30/20 = 1.5.We can also write this as 3/2 or 1.5 : 1, etc.; What this gear ratio means is that the smaller driver gear must turn one and a half times to get the larger driven gear to make one complete turn. So I made a gearing calculator for mopeds a few weeks ago. ... Just pick your bike and your engine then you can mess around with different sprockets and tire sizes and see what you end up with for a final gear ratio. ... most grateful. At present here are the major peds I'm missing. For some of these I'll also need the rear wheel hub gear ...Higher Gear ratio (15 front teeth, 40 back teeth = 2.67) Using the first link, my top speed in 5th would be = 65.19mph*. I want more top speed instead. Lower Gear Ratio (16 front teeth, 38 back teeth = 2.38) Using the first link, my top speed in 5th would be = 73.19mph*. * I used the default settings of 20in tires and rpm of 8250.The Rear Wheel Sprocket can vary, with belt drive models using a 61, 65 or 70 tooth sprocket.
