購入者が知っておくべきこと

🔧

Last of the bulletproof Evos

The 1340cc Evolution is widely regarded as Harley's most reliable big twin, with simple carbureted (CV) fueling and no cam-chain tensioners to fail. Many examples run 100,000+ miles with little more than routine maintenance.

⚠️

Watch oil leaks and vibration

Check for seepage at the three-piece rocker boxes, pushrod tube seals and base gaskets, plus stator/voltage regulator charging faults. Because the Softail engine is solid-mounted, vibration loosens exhaust brackets and fasteners and can crack mounts, so inspect hardware carefully.

💰

Strong collector resale

Carbureted Evo Fat Boys have become sought-after for their solid-disc wheels, shotgun pipes and 'Terminator 2' cool factor, so clean, low-mile stock bikes often sell for more than later Twin Cam Softails. Original paint, matching numbers and factory parts (especially the tank console speedo) add real money.
