I've found that a 13 tooth is better for 300' dirt drags. In sand, i prefer the stock 14, because the 13 makes 4th and 5th gear too similar
Here's the setup on my 2007 polaris predator 500. -Trinity Racing Stage IV full exhaust -170 jets -K&N air filter -Moose 15 tooth front sprocket. hope this helps.

Small sprockets reduce the weight of your bike so that's always a plus. Also a smaller sprocket doesnt get in the way and they look cooler :)
I run a stock rear sprocket and 15 front. does great for 500 ft drags

generally a racing BMX is built for speed, hence they are made lighter than normal bikes and also have a bigger sprocket witch enables the driver( back sprocket) to go faster.
about 13hp when using racing fuel!
if your racing then a Honda 400ex, but if your working polaris makes a 425
The thickness of a rear kart sprocket typically ranges from about 4 to 8 millimeters, depending on the specific design and intended use. Factors such as the size of the kart and the type of racing can influence the sprocket thickness. It's essential to choose a sprocket that matches the kart's specifications for optimal performance. Always refer to the manufacturer's guidelines for precise measurements.

Choosing a 520 sprocket over a 530 sprocket typically results in a lighter weight setup, which can improve acceleration and overall performance in racing or sport applications. The 520 chain also tends to have less rotational mass, allowing for quicker throttle response. However, it's important to note that the 530 sprocket may offer greater durability and strength, making it a better choice for heavier bikes or more demanding riding conditions. Ultimately, the choice depends on the specific performance needs and riding style.
