12 V REGULATOR DRAG SPECIALTIES (ref. 74516-86)

Designed for vintage machines and demanding touring bikes, this solid-state alternator regulator offers a compact and reliable solution to stabilise the charging circuit. Housed in a chrome-finished aluminium casing, it combines retro aesthetics with resistance to shocks and moisture — a great asset for rides in all conditions.

• Voltage: 12 V
• Nominal current: 22 A
• Type: Solid state (no relay contacts)
• Material / finish: Chrome aluminium
• Protection: Designed to withstand moisture and vibrations

The "solid state" principle eliminates mechanical contacts that can wear out or become misaligned, resulting in more consistent voltage regulation regardless of the electrical load (headlights, accessories, chargers). Its chrome finish integrates particularly well with classic-style Harleys while remaining compatible with touring uses where electrical stability is important.

Compatibility (examples): Harley Davidson FXSTS 1340 Softail Springer, FXSTC 1340 Softail Custom, FXST 1340 Softail (1988). Manufacturer reference: 74516-86.
