Cycle Pro Throttle Position Sensor

Cycle Pro Throttle Position Sensors for Harley-Davidson Motorcycles

When a Harley-Davidson's fuel injection system starts hunting for idle, surging under acceleration, or throwing fault codes, one of the first components to suspect is the throttle position sensor (TPS). This small but critical device tells the engine control unit exactly where the throttle plate sits at any given moment, enabling precise fuel delivery, smooth power delivery, and efficient combustion. A worn or failing sensor disrupts that feedback loop — and that's where Cycle Pro steps in.

Cycle Pro LLC has been a trusted name in the powersports aftermarket since 2003. The company is engaged in the development, design, and wholesale distribution of aftermarket parts and accessories for Harley-Davidson, British motorcycles, ATVs, and other recreational power sport vehicles. Having grown into a premier manufacturer and supplier of replacement parts to distributors, importers, and exporters in the United States and abroad, Cycle Pro takes pride in delivering quality that is second to none.

Direct OEM Replacement — With an Upgrade

What sets Cycle Pro's throttle position sensors apart from simply sourcing a used OEM unit is that these parts go a step further. They are direct replacements for OEM Harley throttle position sensors, feature an upgraded design for improved durability, and are engineered to achieve maximum fuel efficiency and power from the engine. That "upgraded from OEM" philosophy means riders aren't just restoring their bike to factory spec — they're potentially improving on it.

Each Cycle Pro throttle position sensor is a high-quality direct OEM replacement designed to help riders reach the greatest possible fuel efficiency and power. The sensors communicate accurate throttle position data to the ECU, supporting smooth acceleration, consistent idle quality, and optimized fuel maps across the RPM range.

Broad Harley-Davidson Fitment Coverage

Cycle Pro's TPS lineup is built around the most common Harley-Davidson fuel-injected platforms, spanning decades of production. Key fitment examples include:

• 2006–2017 Dyna, 2006–2015 FXST/FLST, and 2006–2007 FLHT models — replacing OEM #27659-06.
• 2002–2005 Touring, 2001–2005 Softail, 2004–2005 Dyna, and 2007–2022 Sportster models — replacing OEM #27629-01.
• 1998–2001 Touring models equipped with the Magnetti-Marelli throttle body, replacing OEM #27271-95.

This range of coverage makes Cycle Pro one of the more comprehensive aftermarket sources for H-D TPS units, whether you're maintaining a classic Twin Cam Softail or keeping a late-model Sportster running at its best.
