Chain covers are made up of aluminum and both upper and lower one weighs less than 1 kg.
Things to ponder in case of open chain
1. In India, females with sarees and other tradtional dressing can have long hanging part of cloth which can easily get stuck into sprocket teeths and make bade pull over.
2. Open moving chain has created havocks for young children sitting behind his father, whose leg barely reach to the height of foot pedals.
3. As a rider if you try to raise your side stand during drive and unlucky if any part of your trouser catches the moving chain then be prepared to oiled/greased paint and worse getting engulfed into it.
4. Chain split in a open chain could tore off the pillions calf muscles like water mellon.
Indian bike manufactures have some good idea of many similar issues, thats why they have been trying to put some sort of cover over chains, initially they where fully covered, some new bikes p220 etc have semi covered, where the upper segment of chain is covered to some extent. They are trying to make some balance between security and style.
