If you want to make the ultra pro fork laster longer, you can put a tube reinforcement inside of it. You can see a tutorial for it
here.
Another thing you may need fairly soon are some new grips
Dan's Comp is a good place to browse for grips, but once you find a pair you would want I would suggest searching around for a better price. Dan's Comp has good prices, but the shipping is like $9 so you end up paying around $20 for something you could've found somewhere else online for a total of about $14, or even at a local bike shop for around 7-10 bucks.
Also, after a while, new wheels will be necessary, I would suggest some Demon Metal Cores, a good place to find wheels would be
here, because if you live in the US, shipping is free. It's a great web site for all other scooter parts as well.
