Buyers Guide For Scooter Forks
On a scooter, the fork determines what kind of compression system it will be compatible with.(the bar will also determine this) So, it is not a light choice to make! Let’s check this out.
HIC / SCS
Those forks are coming with a 1 1/8 tubing. It is a standard coming from the cycling world and it is the reason why all the after-market headsets will perfectly fit on those; the top-caps, race-cups and pinch-rings being made for 1 1/8in. You can ride those forks HIC with a compression shim (sold separately) or SCS with a SCS clamp.
Those forks will always come with a IHC compression shim and a pinch-ring since the tube size might vary depending on the company. Regardless, with the shim on it will always reach the 1 1/8in to fit on standard chromo, Ti bars or aluminum bars.
It can’t fit with SCS (well it’s possible but completely useless) but you can buy IHC to HIC conversion shim to fit those forks on oversized bars.
It’s a less common system, so you don’t see it every day. It uses a 1 1/8in fork with a hole at the top to fit a screw from inside the fork. It can’t be fitted with any other compression systems, but there’s some HIC forks that can be converted to ICS.
Wheel sizes compatibility
Standard width of scooter wheels. All fork should be able to fit those.
Rarest of the width sizes. Usually, the wheels with that size will have a core of 24mm to fit normal forks. Still, there are models with 28mm width at the core. Not very common nor useful
More and more popular, all the good companies now have that width option. Always be careful to check if your wheels have a 24mm or 30mm core width to fit pair with the correct spacers. Keep in mind, some forks can fit 24mm wheels with 24mm core and a 30mm wheel with 30mm core but 30mm wheels with a 24mm core might not be compatible with the spacers.

Old standard that now appears on basic scooters.
Still the standard in the scooter industries. All the after-market forks will fit them.
The 120mm now comes stock on pretty much all the mid to high end scooters and for that reason most forks now fits 120mm wheels.
12 Standard (12STD)
That one is a bit tricky. There’s a different standard of wheels / axles / bearings set-up that exists in the scooter world. It will use bigger Wheels (125x30mm). To maintain a good strength for that size, it uses 12mm axles and bearings instead of the classic 8mm one. If you’re looking for a 12STD set-up, be careful to always choose compatible parts.
