There are many options avilable when it comes to upgrading your scooter. Here are just a few.
Many companies manufacture variator kits specifically for your scooter that change the way the gearing engages. This can help you to increase torque lower down in your scooter’s power band, allowing your scooter to be quicker getting off the line and up to speed. Before you invest in one of these, check to make sure the kit you’re buying was made with your scooter in mind — there’s no such thing as a universal variator kit.
Depending on your scooter, an air filter change may or may not make a noticeable difference. But if you can increase airflow from your air box into your engine, it’s a relatively inexpensive way to get a little more power. K & N makes filters for almost everything, including most scooters.
Tires make a huge difference in how your scooter handles. From the factory, unless your scooter was some special race-prepped replica or model, most manufacturers equip their scooters with tires that will give the longest wear life possible — which isn’t always the highest performance. Generally speaking, the grippier the tire, the softer the rubber — meaning they won’t last terribly long. Unless you’re taking your scooter out on the track, you probably don’t need something with obscenely high levels of grip, but you might want something that will stick you to the road a little better through corners and in rainy conditions.
If you’ve got a scooter with a carburetor, you’ll want to replace or upgrade the carb at the same time as the exhaust. Bigger jets and a performance breather are a great compliment to an aftermarket exhaust.
