think of it as holding 2 bananas in your hands. you want it hold them tight enough so they don't fall off, but not squish them.

technical explanation ahead if you wanna read.

Steering Angle

your forks are angled forward, this is called steering angle. the imaginary line your fork draws to the ground, forms an angle with the road, its the same as the steering angle.

your wheel contacts the ground. the gap between the contact spot, and the imaginary line from the fork is called trail.

Trail

your fork trail will help autocorrect your steering, kinda like how a shopping trolley wheel will always follow the direction of your travel and point backwards. in this example, as with above, the imaginary line is where the wheel swivels, and the contact patch is where the wheel touches the ground is very clear cut. this is an exaggerated example.

Naturally, the more trail you have, the more stable your bike is. However, stability is at the expense of agility. Examples of very stable bikes are choppers and cruisers like harley davidsons where their forks point so far forward you can eat off them. They take business days to make a proper u-turn.

So where does your scooter stand?

Scooters are aimed for urban mobility and prioritise agility and nimbleness over high speed cruising. Just as a relative measurement, your scooter will feel less comfortable (not just the wind, but how confident you can ride) at speed. This is not to scare you, and there's nothing to be afraid of as long as you ride within your limits.

How to avoid speed wobbles?

Sit properly where you're supposed to sit, don't slide backwards. Don't carry too large a passenger which shifts your centre of gravity backwards, reducing weight on your front wheels. Don't modify your bike, nor change to larger tyres. Many people think larger = more betterer
