Tooth Chain Transmission



summary

an easy way to understand the ratio of motorcycle sprockets is to consider a 10-speed bicycle with 5 sprockets at the rear and 2 at the front.

choosing the smallest front sprocket and the largest rear sprocket, it is easy for the bicycle to climb from rest and mountain.However, high speeds cannot be reached, and the rider's legs quickly cannot operate fast enough to effectively push the pedals.In fact, riders will "accelerate" or reach their speed limit.

choose the largest front sprocket and the smallest rear sprocket, the bicycle travels slowly and slows down on the hillside.In fact, the rider's legs are hard.However, when on flat ground or downhill, high speeds can be reached, the rider's legs can effectively push the pedals, and the bicycle can reach high speeds.

the same principle applies to motorcycles.reducing the front sprocket and/or increasing the size of the rear sprocket will increase acceleration, but may limit the maximum speed.increasing the front sprocket and/or decreasing the rear sprocket will reduce acceleration and increase the top speed, provided that the engine is strong enough to drive the bicycle to this speed.Of course, on motorcycles, we cannot change the rear transmission ratio when riding (this is why we have a gearbox), so it is very important to choose the correct sprocket transmission ratio before the race.


  • the basics of selecting sprocket drives.

    riders on the new track may need to adjust the sprocket ratio for the best performance of the bicycle.

  1. · If the rider finds that they have never entered the highest gear in the fastest part, the transmission of the bicycle will be significantly too high.This can be corrected by significantly increasing the size of the rear sprocket or reducing the size of the front sprocket or both.(common when road bikes are converted to track use).
  2. · If the rider finds that they are entering the highest gear, but the bicycle does not pull up to only a small part higher than the peak power speed in the fastest part, then the bicycle transmission is slightly higher.this may be corrected by slightly increasing the size of the rear sprocket.
  3. · If the rider finds that they are entering the highest gear and the bicycle bounces off the rev limiter on the fastest section, the bicycle has a shorter gear.This can be corrected by reducing the rear sprocket or adding the front sprocket.
  • as riders become more familiar with the track or as conditions change, this process may need to be reviewed again and again.

    is worth recording the transmission that works on each track.This will allow the bicycle transmission to be set up for the track before arrival, and allow the track side setting to focus another area or more of the machine on the track practice time
