The Importance of Dirt Bike Sprockets in Maintenance
Whether you are a new dirt bike owner or an experienced professional, bike maintenance is a crucial element to your safety and enjoyment. Neglecting any part of your bike could not only render your bike unusable, costing you money and time, but it could also put your life at risk if something goes wrong during your ride. Keep a watchful eye on your dirt bike sprockets and know the signs of excessive wear and tear.
Replace your sprockets if:
You notice tooth damage or decay
You have cupping at the base of any teeth
Your teeth are leaning
A good rule to follow is to also replace your chain when you change out your sprockets. This will allow you to have a nice, clean transition to your new drive system and will increase the life of your new sprockets.
How to Choose a Dirt Bike Sprocket
The type of sprocket you choose to incorporate depends largely on your specific skill level, the speed and/or acceleration you are wishing to meet, and the type of terrain you are riding. An individual enjoying the windy mountains and a rider training on a motocross track are likely going to use different types of sprockets for their bikes. Additionally, dirt bike sprockets and gear ratios are often different than in other cycling sports, so it’s important to have motocross-specific knowledge in this area.
Questions you might be wondering: What does a larger rear sprocket do on a dirt bike, what is a good gear ratio for a dirt bike, and what size sprocket is right for me? We will answer these questions and much more in this section. First, it’s important to understand some of the vocabulary.
Understanding Gear Ratio
Don’t let the bike lingo intimidate you. Gear ratio, otherwise known as sprocket ratio, is simply the number of teeth on the rear sprocket divided by the number of teeth on the countershaft sprocket (aka the front sprocket). When the gear ratio number is higher, the gearing is then lower. The opposite is also true- when the gear ratio number is lower, the gearing is then higher. A basic rule to follow is that the more teeth on the rear sprocket, the lower the gearing is overall.
Lower gearing leads to faster acceleration and quicker take-offs, which comes at the expense of a lower top speeds. This is also know as gearing down.
A higher gear ratio or gearing up will give you the opposite effect. You will be slower off the line but will be able to achieve higher top speeds.
Reaching the right gear level for your skill level and riding terrain will allow you to optimize your bike’s performance. To do this, you will want to choose your front and rear sprockets wisely, to meet the gearing that you hope to ride.
