How much speed can be increased by changing from 14 to 16 teeth on a motorcycle?
2 Answers
Specific speed increase needs to be analyzed based on the motorcycle's brand and power. Here is some extended information about modifying the rear sprocket: Reducing the rear sprocket: If the rear sprocket is reduced, it can increase speed slightly on flat roads or save some fuel when riding at medium speed in high gear, but the power will decrease when climbing hills, starting, or carrying loads, or it may require shifting to a lower gear. Increasing the rear sprocket: If the rear sprocket is increased, the climbing ability will be slightly better, but the top speed will decrease, giving the feeling that the bike cannot run fast. Notes: The gear ratio of the motorcycle sprocket is designed based on the engine power, transmission gear ratio, and other factors, taking into account various usage conditions.
I remember modifying the rear sprocket of my motorcycle before, changing it from 14 teeth to 16 teeth. The speed indeed increased by about 14%, which sounds pretty cool, right? I'm the kind of person who loves riding on highways, and after the change, the top speed increased by more than ten kilometers, making the bike feel more stable. However, the acceleration noticeably slowed down, and starting off felt much more laborious than before, especially in traffic jams. Additionally, with this kind of modification, you need to pay attention to the chain length—too long and it might derail, too short and it could damage the sprocket. I didn't adjust it properly before, resulting in a loose and noisy chain. Also, the engine load increases; if the original engine isn't powerful enough, the acceleration might actually be worse than before the change. I suggest test riding a short distance first to see how it feels—don't think swapping a sprocket is the end of it. Overall balance is the most important thing.
