Cable bike or throttle-by-wire? Settle it first

The map: Touring models are throttle-by-wire from 2008; the M8 Softails (2018-on) and the Revolution Max bikes are TBW; Dynas were cable to the end of the line, and the Evo Sportster was cable to 2022. It changes the whole shopping list — a cable bike going to taller bars needs extended throttle, clutch and idle cables plus a longer front brake line, while a TBW bike needs no throttle cables at all, just wiring extensions and the brake line. It also gates the grips: cable bikes take dual-cable throttle-sleeve grips, TBW bikes take grips made for the sensor tube, and cross-buying is the single most common grip return.

The ape-hanger arithmetic

Stock cables tolerate a modest rise; genuinely tall bars need everything longer, and the tidy answer is a height-matched cable-and-line kit — sold by bar height, so measure the bars, not the vibe. Barnett dominates our cable stock (more than 800 lines) partly because of how cables are bought: measured housing ferrule-to-ferrule, excluding the free wire. For a custom routing, run a piece of string along the intended path first; it is the oldest trick in the book because it works.

Wiring is the half of the job people forget to price. Switch wires either extend (solder or pre-made extension harnesses, sold per year range) or, on many 2014-on Touring bikes, the connectors are small enough to fish through the bars. Either way, internally-wired bars must be drilled or dimpled for it — check the listing.

The small stuff that decides whether it wobbles

Measure the clamp area: most Harley bars are 1 inch where the risers grip, fat-bar setups run 1-1/4 inch, and the two do not mix without matching risers — measure the bike, because model folklore is wrong often enough to cost postage. While you are there, look at the riser bushings: bars that knock out of line over bumps are collapsed rubber bushings, a few pounds to fix. And on mirrors: genuine Harley mirror threads are 5/16-24; a lot of imported aftermarket stock is metric M8 — close enough to start threading, wrong enough to wobble forever. If a mirror will not stay put, check the thread before blaming the ball joint.
