What Buyers Should Know
Heat Management Improved
The Milwaukee-Eight 107 runs significantly cooler than the Twin Cam it replaced, thanks to a 4-valve-per-cylinder head design and improved oil cooling. Riders report far less leg heat discomfort on long rides.
Watch for Cam Tensioner
Early 2017-2018 models had reported issues with primary chain tensioner wear and some cam plate oil leaks — verify service records and check if these have been addressed before buying.
Strong Resale Value
The M8 generation holds its value exceptionally well due to high demand and Harley's loyal fanbase, with clean low-mileage examples often retaining 70-80% of MSRP after several years.
