As an avid motocross rider, I have had the opportunity to ride various dirt bikes over the years. One bike in particular that has always caught my attention is the Yz 85. It is known for its lightweight frame, fast acceleration, and nimble handling. However, as I became more experienced and started competing in races, I realized that the stock engine of the Yz 85 was lacking in power and performance. This is where a big bore kit comes into play.

A big bore kit is essentially an aftermarket upgrade that increases the displacement of the engine by enlarging the piston and cylinder.

In the case of the Yz 85, it typically increases the displacement from 85cc to 105cc or even 110cc.

Why Choose a Yz 85 Big Bore Kit?

The Yz 85 is already known for its power and performance, but adding a big bore kit can take it to the next level. With an increase in displacement, you can expect significant gains in horsepower and torque, making your bike more competitive on the track.

Factors to Consider when Buying a Yz 85 Big Bore Kit

1. Brand: When it comes to aftermarket parts, choosing a reputable brand is crucial. Look for brands that have been in the market for some time and have positive reviews from other riders.

3. Displacement Increase: Big bore kits come in different sizes, ranging from 100cc to 150cc or more. Consider your riding style and needs to determine the right displacement increase for your bike.

4. Compatibility: Not all big bore kits are compatible with every Yz 85 model. Make sure to check if the kit is compatible with your bike’s year and model before making a purchase.

Installation Process

Installing a big bore kit can be a complex process, and it’s recommended to have it done by a professional mechanic. However, if you have experience working on bikes, you can attempt to install it yourself by following the manufacturer’s instructions carefully.
