Hello,

London roads are just in such bad condition, full of potholes, speed bumps etc and seems like my scooter suspension is taking a hit.

So for a bad road conditions, as mentioned above and to get a smoothest ride, should I adjust the rear shock to position 1 or 5? thank you

Neither, if only it were that simple.

That adjustment doesn't adjust the 'hardness' of the spring, nor the damping. It merely adjusts the 'preload' which is how much the spring is pre-compressed without being pushed up or down by bumps or the road falling away from the tyre. People say it adjusts ride height but it's a tad more complicated than that.

What you should do is to adjust the preload based on your weight, so that with you on the bike the suspension sits at the top of the bottom 2/3rds of travel, so that the suspension can still go down (the bike go up) a 3rd of the travel if the roadway drops away from you.

Sadly it won't affect ride quality. You need adjustable damping for that, which I don't think they do on scooters in general.

You might want a "soft" spring position, which will be 1. However, you ought to try out the various positions, and see what you feel about them. If you're less than average weight, best may tend to 1; if you're above, then you might find best tends to 5.

Find a quietish piece of road with a bump in it that you can use for testing, and try it out!

By the way, is your shock absorber working properly? You just might find that if it's very old, the damping part of the shock absorber is no longer doing its job (if for instance the fluid has leaked out). Nore that the pressure of your back tyre and manufacture may also have some effect on ride quality.

If you want a smooth ride, don't ride a scooter. Tiny wheels do not work well on potholed roads. If you tried a bike or moped with 17"-18" wheels you will probably notice a huge difference. What model scooter do you have? On some of the Chinese makes, the rear shock is very cheap and nasty with virtually no damping. You could try changing the shock, but depending on how old the scooter is or how long you intend to keep it that might not be really viable.

For a given load, that’s exactly what it does. Preload is for setting sag, not adjusting ride comfort or stiffness.

This article explains preload pretty well. Preload isn't for adjusting damping or ride height etc (although it does have an effect on ride height), it's for correctly setting sag.

Why are you riding through the potholes? Stick out nice and wide so you've got the room to avoid them.
