Introducing the Ultima 70-226 2.0kw Top Post Thunderfire Starter, an essential upgrade for Harley-Davidson Big Twin motorcycles manufactured between 1989 and 2006. This high-performance starter is designed to deliver reliable starting power, ensuring a quick and easy engine ignition.

The Ultima 70-226 starter boasts a powerful 2.0kw output, which is significantly more than the standard OEM starters. This increased power enables the starter to crank the engine faster, reducing cranking time and making starting, especially in cold conditions, a breeze.

The Ultima 70-226 starter features a durable cast aluminum housing, which not only looks great but also offers superior heat dissipation. The starter's robust construction is designed to withstand the rigors of regular use on a Harley-Davidson motorcycle, ensuring long-lasting performance.

This starter is also compatible with a wide range of accessories, including battery chargers and maintenance-free batteries. Furthermore, the starter comes with a convenient mounting kit that allows for easy installation, ensuring a secure and vibration-free fit.

The Ultima 70-226 2.0kw Top Post Thunderfire Starter is an excellent investment for any Harley-Davidson Big Twin owner who values quick and reliable starting power. By upgrading to this high-performance starter, you'll not only improve the starting performance of your motorcycle but also enhance your overall riding experience.

The Ultima 70-226 2.0kw Top Post Thunderfire starter is a popular aftermarket option for Harley-Davidson Big Twin motorcycles manufactured between 1989 and 2006. Here are some pros and cons to help you decide whether this starter is the right choice for your motorcycle.

Pros:

1. Increased Starting Power: The Ultima starter delivers more cranking power compared to the OEM starter, making it a popular choice for motorcycles with large engines or heavy accessory loads.

2. Faster Cranking: The 2.0kw starter offers faster cranking times, which can be beneficial in cold weather conditions or when the battery is weak.

3. Durability: The Ultima starter is known for its robust construction and high-quality materials, which can lead to longer service life and fewer replacement needs.

4. Improved Performance: Some riders report improved engine performance and smoother starts after installing the Ultima starter.

Cons:

1. Cost: The Ultima starter is more expensive than the OEM starter, which can be a deterrent for some riders.

2. Installation Complexity: Installing the Ultima starter requires some electrical modifications, such as wiring, and may involve additional labor costs.

3. Size: The Ultima starter is larger than the OEM starter, which may require additional clearance modifications or custom mounting solutions.

4. Weight: The Ultima starter is heavier than the OEM starter, which may impact the overall weight and balance of the motorcycle.

Conclusion:

The Ultima 70-226 2.0kw Top Post Thunderfire starter offers several advantages, including increased starting power, faster cranking, and improved durability. However, it also comes with some disadvantages, such as cost, installation complexity, size, and weight.

If you frequently experience starting issues, ride in cold weather conditions, or have a motorcycle with a large engine or heavy accessory load, the Ultima starter may be a worthwhile investment. On the other hand, if your motorcycle starts reliably and you're not looking to modify it significantly, the additional cost and complexity of installing an aftermarket starter may not be necessary.

If you're considering purchasing the Ultima 70-226 2.0kw Top Post Thunderfire starter, make sure to carefully evaluate your needs and consider the pros and cons outlined above.
