Harley-Davidson Sportster V-Twin Ironhead Engine Rebuild Time-Lapse | Redline Rebuild - S1E6

After three months, 20,000 photos, and more than our share of hurdles (especially finding parts), we’ve completed another Redline Rebuild time-lapse video. This time around, Hagerty’s Davin Reckow tackles a two-wheel project, a bit of a Frankenstein bike with the heart of a 1957 Harley-Davidson XL Sportster. No seriously, its engine is an ironhead V-twin from a first-year Sportster. So strap on your helmet because we’re about to speed things up a bit.
