To be considered "street legal", a motorcycle must meet certain size and weight requirements.

The most important thing is that the vehicle's cylinder capacity does not exceed 750 cc (cubic centimeters).

So if you are looking at a Honda CRF450R or Kawasaki ZX-14 then they are illegal as their engines do not fit this limit.

However, there are other smaller bikes like the Yamaha YZF-R6. This has a displacement of 699cc, which would be considered street legal.

Regarding the maximum weight, the rule states that the combined weight of the pilot and his passenger cannot exceed 250 kg (551 lbs).

For example, if you're riding with someone who weighs 200 kg (441 lbs), your total weight will be 450 kg (992 lbs) - well over the limit.

Another important point is that the motorcycle must also have a ground clearance of at least 150 mm (5.9 inches).

In other words, the front wheel must be able to pass over any obstacles in front of it without touching them.

Finally, the vehicle must be equipped with rear view mirrors, turn signals, brake lights, horn and headlights.

These items are required by law, but some manufacturers choose to include them anyway; so unless you've made changes, you shouldn't have any problems here.

Many people convert their old bikes to electrics by installing a battery. These batteries are usually located under the seat or behind the gas tank.

These are typically 12V lead-acid batteries, although lithium-ion batteries are becoming more and more popular.

As these batteries age, they lose capacity and become less efficient, so they need to be replaced. Some people even use several packages in a row to create a higher capacity system.

If you plan on making your bike electric, consider upgrading the electrical system. First, you need to decide how much power you want to pull from the battery.

Then you need to determine exactly how many cells you need. Finally, you need to figure out how big each cell needs to be.

The easiest way to calculate the number of cells needed is to multiply the voltage by the current. For example if you have a 12v battery you will need two cells like 2 x 12 24.

If you want to operate an LED light strip, you can also use a single cell battery. However, you need to increase the current to compensate for the lower voltage.

Once you've determined the number of cells you need, you need to measure the size of each cell.

This allows you to determine how many inches in width and height each cell needs to be to fit in the frame. The most common sizes are 9×12 inches and 10×14 inches.

Finally, you need to install the battery. Be sure to follow the instructions carefully so as not to damage the battery.

Also, be sure to keep the battery away from sources of water. After installing the battery, test it to make sure everything is working properly.
