Performance Parts and Upgrades
Currently your bike is probably begging for some more airflow from the exhaust and higher top speeds, lets address that.
Looking for some initial upgrades?
Replacing the Front Sprocket
From the factory, these bikes can come with either a 14T, 15T or 16T front sprocket. Tey are often geared very low and this can hurt tops speeds. The most popular front sprocket to swap to is a 16T. This will give you a a higher top speed and still some good acceleration. A 17T sprocket is also another option some run, allowing for even higher top speeds, but if you live with hills or varying terrain, the acceleration can feel a bit sluggish. When upgrading the sprocket the chain guard can sometimes make contact with the chain, it is recommended to dremel a small portion of the chain guard to prevent this slapping noise. This upgrade often is paired with a new chain as well, as the stock chain is fairly cheap and can stretch.
Chain Upgrade
The stock chain is prone to stretching and it can be frustrating to adjust the chain tension often. For a cheap upgrade, the RK Racing chain is a great option. This chain is a 110 link chain and will fit for any of the sprocket options. The factory chain is a 108 tooth and many people trim will their new chains down to match the 108 links. This just keeps the original adjustment amounts. A bit better looking chain is the Gold RK Racing chain, but it is a bit more expensive. Be sure to lubricate your chain often and keep it clean. A dirty chain can wear out your sprockets and chain much faster.
Exhaust Upgrade
The stock exhaust is very quiet and very restrictive. The most popular exhaust is the two piece low mount exhaust below. This requires zero modifications and is a direct fit. Any other exhaust will not fit directly and will require significant bending and modifications. This exhaust will require two copper crush gaskets to prevent exhaust leaks. This will also need to be paired with your muffler of choice, the most popular being the 51mm carbon fiber muffler, the most common length is the short 310mm. This comes with a mounting bracket that will directly bolt to the rear foot peg mount. This slip on includes a removable baffle and can be pretty loud without it. Be sure to loctite the baffle screw as this is known to vibrate out and get lost. This exhaust setup will require no welding or cutting and is a direct fit. Be sure to retune and possibly jet your carburetor after this upgrade.
Tire Upgrade
The stock tires are very cheap and can be very slippery in the rain. The most popular tire upgrade is the Michelin Power Pure SC. The front tire is a 120/70-12 and the rear tire is a 130/70-12. Some may opt for a 140/70-12 rear tire for a bit more grip and a bit more of a sporty look. These tires are the best you can buy for the bike. The handling is greatly improved on turns and the grip is much better.

With these upgrades, you should be able to reach a top speed of 60-65mph and have a much more enjoyable riding experience. The bike should be much more responsive and have a bit sportier exhaust note now. Lets tackle some cosmetic modifications next.
