Transpo Parts & Accessories

Transpo make solid-state voltage regulators and rectifiers as direct replacements for the original mechanical units on classic Harleys — the parts that were a known weak point on bikes from the 1950s through the early Evo era. Modern electronics with no contact points to burn or moving parts to wear, in black or chrome to suit restoration or custom finish.

Coverage runs from vintage all the way through to current platforms. Sensible upgrade when an old regulator finally gives up — fits where the original sat, sorts the charging system out, and lasts longer than what came off.
