SOME SAY YOU SHOULD CHANGE. A differential ratio describes how many output revolutions of a gearbox it takes to do one turn of a wheel. Through simulation we can understand how a system works, how it behaves under predefined conditions and how the performance is affected by different parameters. See the chart below the table for typical ratios. Just like the mountain bike, if you try to start in a low gear it will take massive amounts of effort and could damage the engine if it does not stall first. The final ratio comes from the gearbox ratio multiply with diff ratio, which means if both 1, then the final ratio is 1 => wheels spins same speed as motor. All of the above is correct. Therefore a higher ratio diff would give a lower top speed but a more rapid acceleration, and conversely a lower ratio diff will give a higher top speed (or more relaxed cruising since lower engine revs are required. Gearing up, like with a smaller rear sprocket, decreases the final drive ratio and adds more top speed to your motorcycle or ATV. We put this nifty gear calculator together to help you find the best ratio. It's a bit to get your head around but it works. "Tall" gears and "short" gears are referring to the gear ratios. But I would really like to put in a 3. 73 will provide the best 'Bang for the Buck' because of the slightly higher acceleration "if your going to generate extra cabin noise, you may as well select the ratio that gives the best acceleration". Hence low gears provide better acceleration.
