The Milwaukee 8 engine is generally considered to be a better engine than the Twin Cam due to its increased power, improved exhaust system and larger displacement.
The Milwaukee 8 has been touted as the best of both worlds when it comes to motorcycle engines. It offers more power than the Twin Cam, thanks in part to its larger displacement and advanced exhaust system that allows for greater efficiency. Additionally, the Milwaukee 8 offers a smoother ride with improved torque delivery over its predecessor. With this combination of features, it's no surprise why riders have come out in favor of the Milwaukee 8 as their preferred choice for an engine upgrade or replacement. Furthermore, careful engineering by Harley-Davidson ensures that these benefits are delivered while still maintaining an iconic look that stays true to classic Harley style and design principles.
