I'm not sure if there's any evidence to support that a scooter's front wheel is easier to wash out. Due to their smaller wheel size they're actually better on the curves than a large wheeled MC, which tends to have better stability on the straightaways, and less on the turns.
Despite common misconceptions, scooters are just as dangerous as motorcycles, but too many times it's because of operator error, than the bike's overall design. I don't agree with the first assessment in the description below as I've never felt any less stability on a scooter compared to a MC, nor do I agree that they are not true commuter bikes as the author seems to only think of 50cc scooters as the only kind out there.
https://www.motorcyclelegalfoundation.com/are-scooters-safe/Scooters are considered as dangerous as riding a MC.Smaller Wheels – Scooters typically have smaller wheels than a motorcycle. They will be less stable on the road compared to a motorcycle primarily due to the smaller wheels giving less gyroscopic effect (hence the need to be upright). They will also be more susceptible to react to the small hazards in the road, such as potholes, debris, and bumps.
Less Visibility – It’s difficult to see motorcycles in traffic. A scooter, which is smaller than a typical motorcycle, will be even more difficult to see, putting you in more danger when you’re surrounded by heavy traffic, as other motorists may not recognize a scooter and rider in their path on the road.
Lack of Gear – Scooters are not widely seen as a true commuter vehicle, so riders tend not to wear the proper safety gear while riding compared to a normal motorcyclist. They opt to ride without a helmet, proper jacket, pants, or even good protective footwear. If you’ve been on vacation to a resort or beach, you may have seen the scooter rentals available. They don’t typically ask for a motorcycle license or if you brought proper safety equipment. Therefore, you’re more at risk sans protective gear on a scooter than being on a motorcycle with ATGATT.
