This blog provides kind of insight into my earlier blog post on the dimensions of my dad’s Suzuki GP 100. Readers came up with interesting technical questions and I would try my best to answer them, in a simple way.
Overall length, width and height of a motor cycle are not that hard to understand. Imagine the GP 100 as a wooden bench in your room. There is an overall length, width and height for that too. Got the point? Apply the same to GP 100 and you are okay.
Now, the wheelbase. Yeah. Take a look at the front and rear wheels of a motor bike. There are center points on each wheel. At each center point, there is an axle. Good. The distance between those front and rear axles is called the wheelbase. It is a sort of length.
Ground clearance. Ignore the wheels. Now what is the lowest point of a motor cycle’s underside? How high it is from ground level? Five inches? Seven inches? That is the ground clearance.
Seat height? Simple. You sit on a motor cycle and try to balance the machine between your legs. Are both your feet flat on the ground? Or is it difficult for your toes to reach the ground? That’s it. This all depends on how high your seat is above ground level. So the distance from ground to the top of the cushions represents Seat height.
Dry mass. Fine. A motor cycle needs fuel to keep it going. For the proper functioning of its mechanism engine oil and transmission oil levels should be duly maintained. Now exclude all this. Imagine the bike has only just rolled out from the production line. You weigh the machine at that precise moment and you get the dry mass of it.
Torque and horse power. Picture yourself paddling a push-bike. You put force on the paddle to keep it going. Where do you apply force? On the paddle. What happens then? The paddle turns a spike wheel that is coupled to the rear wheel. Right. Now, when you apply force to the paddle so that it turns, then there exists something called ‘torque’ there.
This same thing happens inside motor cycle engines. But the part you did when you were paddling a push-bike is now taken up by a piston. Force is applied on this piston when the engine burns petrol. (I am trying to be very simple, so I may sound off hand sometimes. However, my objective is that you understand this).
The piston then turns a crankshaft. Again there is a ‘torque’ here. That is; a force that turns something in a circular motion around a central point, transmitting energy. It is measured in Newton-meters, normally. Suzuki GP 100 torque is 10 Nm.
Okay we came to energy. The rate of transferring energy is power. It is measured in horsepower. This term is said to be used by James Watt when he invented the Steam Engine and explained its performance compared to the power of horses. It is now a unit of measurement for power.
A Suzuki GP 100 motor cycle’s power is measures 12 HP.
Right. In this post we discussed the overall dimensions of a Suzuki GP 100 motorcycle in a simple way so you can understand these terms without much hassle. Then we explained the basic idea of torque and horse power of the GP 100.
We believe this post would greatly help readers who interested in Suzuki GP 100, specially the collectors of vintage Japanese bikes to get their bearings of the machine in more detailed, yet simplified manner. Meet you in the next blog!
