In the past two years, cruising motorcycles have become a big hit, which has also led to the popularity of belt driving. The advantages of belt drive are less vibration, less noise, smoother, and almost maintenance-free, but the disadvantages are also obvious: the price is several times more expensive than the chain, the power is sluggish during starting or rapid acceleration, and it is easy to slip.
Many people will think that if we can combine the advantages of chain and belt, it will bring a major change of transmission. As the industry leader of the Chinese motorcycle chain, CHOHO chain released its new silent chain at China Chongqing Motorcycle Expo, establishing a new chain transmission system based on the principle of tooth-shaped chain meshing and integrating roller sleeve chain structure to replace the belt.
Significant advantages
1. The silent effect is 15% higher than conventional roller chains, which is only slightly higher than belts as shown in the noise comparison waveform.
2. 600 hours wear elongation rate is less than 0.1%, which is significantly less than the conventional chain.
3. The tensile strength is increased by 20% compared with the roller chain, and it is not afraid of large torque output instantly.
4. The transmission efficiency is improved by 0.68%, which can make the rider feel power improvement according to the test user feedback.
5. Through the maximum 40,000km of a single vehicle and 120,000km of the accumulated road test, the durability far exceeds the ordinary chain and is close to the life of the belt.
