In a Diamond frame, the steering head is connected to the chassis via a single beam. Though it might seem less strong this way, but it is actually pretty strong. The biggest different here is the down pipe that goes from the steering head which is actually helpful to help the engine remain steady since the engine is hanging off the backbone and is a stressed member of the frame. This is something you can observe in bikes like Honda Unicorn/Livo, Yamaha FZ, Bajaj Pulsar 135 onwards, etc. The reason for this is the rugged and city use for which the bikes are made. This means unlike the bikes with lighter frames who are track machines or for highway rides, these bikes are more towards rough usage and to handle and take pretty much anything and everything. Hence this frame can be best seen on commuter bikes.
The advantage of such frames is that they are really light in weight which allows for lighter bikes and also since the engine is hanging off the bike, that allows to save a lot on making the cradle to hold the bike allowing for cost cutting and hence a lot cheaper frame. This all adds up to the overall cost cutting and also a lighter bike.
Diamond frames don’t have any magic properties in them to make the bike fly. But they are very able and efficient frames to keep the bike together and keep it going on the road without any fuss. Since it is a very cost efficient frame which even performs decently, hence it is a hot favorite to go to for many bike makers for most of their commuter sport bikes. But all in all the diamond frame is a pretty good frame for your motorcycle to have.
