Why the Kx85 Big Wheel Kit is Necessary
When I first started riding my Kx85, I quickly realized that the stock wheel size just didn’t cut it for the terrain I wanted to tackle. That’s when I discovered the Big Wheel Kit, and it completely changed my riding experience. The bigger wheels give me better stability and control, especially over rough trails and uneven surfaces. I felt more confident pushing my bike harder because the larger wheels roll over obstacles like roots and rocks much more smoothly.
Another reason the Big Wheel Kit became necessary for me is the improved handling. The taller wheels increase ground clearance, which means I’m less likely to get hung up on obstacles. This also helps with cornering and maintaining speed through technical sections, which was a struggle before. Plus, the kit doesn’t just boost performance—it also enhances the overall look of my bike, giving it a more aggressive and capable stance.
In short, the Kx85 Big Wheel Kit is essential if you want to maximize your bike’s potential. It transformed my rides from frustrating to fun, letting me explore tougher trails with ease and confidence. If you’re serious about getting the most out of your Kx85, I’d say the Big Wheel Kit is a must-have
My Buying Guides on Kx85 Big Wheel Kit
When I decided to upgrade my Kawasaki KX85 with a big wheel kit, I quickly realized there are several important factors to consider. Here’s a guide based on my experience that can help you choose the best KX85 big wheel kit for your needs.
Why I Chose a Big Wheel Kit for My KX85
I wanted to improve stability and ground clearance on rougher terrains. The bigger wheels also gave my bike a more aggressive look and allowed me to tackle bigger obstacles with confidence. If you’re looking to enhance your bike’s off-road capability, a big wheel kit is definitely worth considering.
What to Look for in a KX85 Big Wheel Kit
There are several components and features I checked before making my purchase:
- Wheel Size Compatibility: Make sure the kit fits the 2001-2019 Kawasaki KX85 models. I double-checked the wheel diameter and width specs to match my riding style. Common sizes are 17-inch front and 14-inch rear wheels.
- Quality of Materials: I looked for kits with high-grade aluminum hubs and sturdy steel spokes for durability. Cheap materials can lead to frequent maintenance issues.
- Included Components: Some kits come with hubs, spokes, rims, tires, and sprockets, while others might only include the wheels. I preferred a complete kit for convenience.
- Tire Type: Depending on where you ride, I chose tires with aggressive knobs for better traction in mud and loose dirt. If you mainly ride hardpack trails, a different tread pattern might suit you better.
- Installation Ease: I read reviews to find kits that are relatively easy to install or come with clear instructions. I wasn’t looking for a complicated upgrade that required professional help.
My Favorite Brands and Where I Bought My Kit
From my research and experience, brands like Pro Taper, Dunlop, and Sun Rims offer reliable big wheel kits and components. I purchased my kit from a reputable motocross shop online that provided good customer support and warranty options. Check for seller ratings and return policies before buying.
Additional Tips from My Experience
- Check Your Suspension: Bigger wheels can affect your bike’s suspension geometry. I adjusted my suspension settings after the upgrade to maintain proper handling.
- Sprocket Compatibility: Sometimes the new wheels require different sprocket sizes. I made sure to get sprockets compatible with the kit to avoid chain issues.
- Budget Wisely: Big wheel kits can vary widely in price. I balanced cost with quality to avoid cheap kits that might cost more in the long run due to replacements or repairs.
- Test Ride: If possible, test ride a KX85 with a big wheel kit installed before buying. It helped me understand the difference in handling and fitment firsthand.
Final Thoughts
Upgrading my KX85 with a big wheel kit was one of the best decisions I made for my dirt biking adventures. It gave me improved control and confidence on tougher trails. By considering the factors above and doing a bit of homework, you can find the perfect big wheel kit that suits your riding style and bike model. Happy riding!
