What makes forged aluminum wheels different from cast aluminum?

Forged aluminum wheels are made by forcing aluminum into a mold under extreme pressure. This process creates a denser, stronger, and lighter material compared to cast aluminum, which is simply poured into a mold. This results in improved performance characteristics like reduced weight and increased durability.

What is the benefit of back-cutting the rim lip?

Back-cutting the rim lip reduces the overall mass at the outer edges of the wheel. This directly lowers rotational inertia, making it easier for the wheel to spin up and slow down, which can improve acceleration and braking response. It also contributes to a reduction in unsprung weight.

Does this wheel come with a tire or hub assembly?

This product listing is for the Performance Machine Revolution forged wheel only. Tires, tubes, and other mounting hardware are sold separately. Please ensure you have the correct hub assembly or order one if needed for your specific motorcycle model.

Product Details

When you're looking to give your motorcycle a serious performance upgrade, starting with the wheels is a smart move. The Performance Machine Revolution wheel is built for riders who demand the best in both looks and function. This 21x3.5 inch wheel is crafted from forged aluminum, a process that creates a stronger, lighter wheel than traditional cast aluminum. This means less rotational inertia, which helps your bike accelerate and handle more responsively.

The Revolution wheel features a unique 9-spoke design that transitions into an 18-spoke pattern, giving it a dynamic and aggressive look. Performance Machine also went the extra mile by back-cutting the rim lip. This reduces mass at the outer edges, further decreasing rotational inertia and unsprung weight. Less unsprung weight means your suspension can react more quickly to road imperfections, improving ride quality and handling. It comes equipped with Raceline Series hubs, where every bit of excess material has been machined away to maximize weight reduction.

Each Performance Machine wheel is tested in-house to ensure it meets stringent standards, and they are proudly made in the USA. This wheel is a solid option for anyone looking to reduce weight and improve the performance and appearance of their motorcycle.
