When converting the handlebars, the handlebars themselves are often the easiest part. The crucial question is whether the brake line, clutch cable or hydraulic line, throttle cables and electrical wiring can safely reach the new height. A single line that is too short or incorrectly routed can halt the entire conversion.
1. First, clearly identify the vehicle
“Harley Softail” is not enough information. The model, year of manufacture, ABS equipment and the existing control components determine the connections and lengths. Particularly important are:
- Throttle cable or electronic throttle (Throttle-by-Wire)
- Cable clutch or hydraulic clutch
- ABS or non-ABS
- stock or already modified risers
- internal or external cable routing
Also check for any already installed extensions. A used bike may no longer be in its original condition, even if the handlebars look stock.
2. Don't just measure the handlebar height
For the required length, the entire path from the connection to the control counts. Handlebar height, width, pullback, riser height and the planned routing collectively change this path. A 14-inch handlebar therefore does not automatically require the same 14-inch kit on every model.
A practical way to plan is to trace the future path of the lines with a flexible cable or string. Plan for clean curves and room to move. The final selection must still be made according to the specifications of the kit or line manufacturer.
3. You must check these lines and cables
Brake line
The brake line is safety-critical. It must not be under tension or rub against the tank, fork or sharp edges. On ABS models, the connection type and system design must match the vehicle. After working on the hydraulic braking system, proper filling, bleeding and a leak test are mandatory.
Clutch
For a cable clutch, the length, adjustment range and bend radii must be correct. A hydraulic clutch, on the other hand, requires a suitable hydraulic line and then the same care as the brake when checking for leaks and bleeding.
Throttle
Throttle cables need to be routed without tension and the throttle must return cleanly in every handlebar position after being released. With Throttle-by-Wire, the focus is instead on electrical wiring, connectors and clean internal or external routing.
Switch cables
Switches, turn signals, horn and other controls require sufficiently long lines. Connections must be routed protected, strain-relieved and without rubbing. Improvised pinched areas in the handlebars or loose connectors are not a proper solution.
4. Complete kit or individual lines?
A vehicle-specific complete kit can simplify planning because the main components are matched to a defined model, year of manufacture and a specific handlebar height. However, it does not replace checking against your actual setup. ABS, clutch type and already modified risers must match in particular.

Individual lines make sense if your conversion deviates significantly from stock. However, length, connections and approval must then be planned individually. Our guide Top 3 Handlebars Compared will first help you choose the right handlebar concept.
5. Post-installation check
- Move the handlebars slowly to the left and right stops
- check whether the RPM or throttle is affected by the movement
- Check brake and clutch lines for tension, kinks, contact and rubbing points
- Check clearance to the tank, fairing, speedometer and ignition lock
- test all electrical functions
- Check hydraulic systems for leaks and correct pressure point
- Tighten and secure fasteners according to the manufacturer's specifications
Our conclusion
A good handlebar conversion does not start with disassembly, but with an inventory. Anyone who plans the vehicle, handlebar geometry and all control lines together saves reordering and avoids dangerous compromises. For the parts search, it is best to send us the model, year of manufacture, ABS status, desired handlebar height and a photo of the current setup.
