Although the weight of a machine is not a very important factor to car drivers, the case is different when it comes to bikers for one obvious reason: while cars have four wheels, bikes have two wheels; hence, you will be required to control the weight of your motorbike to avoid toppling. Heavier motorbikes are certainly more stable when riding, and any turbulence emanating from passing trucks can do very little to rattle the bikes. However, heavy bikes have a downside as is the case with most good things. The bike should match your muscle power or you risk falling and sustaining injuries, some of which could lead to permanent disability. It can be a good idea to hit the gym and do a bit of weight training so you can manage the weight of your motorcycle.
If you’re planning to carry supplies or a passenger through a hilly terrain, then torque is very important. A common motorbike parlance, torque simply refers to how well your motorcycle can maintain its top speed when subjected to extra stress (e.g. uphill ride, load weight etc.), and it is measured in kg/m. Check any new bike for torque before you can spend your money on it.
