Top contenders for reliability:
* Twin Cam 88 (1999-2006): A workhorse engine known for its durability and relative simplicity. Many still run strong today.
* Twin Cam 96 (2007-2017): An evolution of the 88, with more displacement and a stronger bottom end. It's still considered a solid engine.
* Milwaukee-Eight 107/114 (2017-Present): Harley's latest engine family. It's generally reliable, with improvements in efficiency and smoother power delivery. However, it's still relatively new, so long-term reliability is yet to be fully established.
Engines with mixed reputations:
* Evolution (1984-1998): A solid engine, but some models had camshaft issues, especially early versions.
* Sportster 883/1200 (various): Widely popular and generally reliable, but some owners have reported electrical or valve train problems.
Key factors to consider:
* Maintenance: Regular servicing and proper maintenance are paramount for any engine's longevity.
* Riding style: Aggressive riding or high-speed cruising can put more stress on the engine.
* Model year: Early versions of any engine may have more quirks or issues compared to later models.
It's essential to note: Even the most reliable engines can have problems, and individual experiences vary greatly. It's always best to do your research on specific models and consult with experienced Harley owners or mechanics.
