HTTMT MT299-002 Fork Clamp Turn Signal Kit

The HTTMT MT299-002 kit is designed to relocate front turn signals on bikes with 39mm fork tubes. It includes a high-quality fork clamp kit that clamps securely around the fork tubes and provides a stable mounting point for signals. Build quality emphasizes durability in typical riding conditions, with a finish that resists wear and corrosion. The kit is marketed as a complete relocation solution, reducing vibration and improving signal visibility. Installation is straightforward for riders comfortable with basic mechanical work on motorcycles. This kit is suitable for Harley Softail models and other 39mm fork applications that require a clean relocation of front indicators.
Key features include robust clamps compatible with 39mm forks, a comprehensive installation kit, and a focus on secure signal relocation. For riders seeking a black, integrated look that complements dark bike aesthetics, this clamp option provides a cohesive appearance. The MT299-002 is a practical choice for riders who want a reliable, complete solution without needing additional hardware. Potential buyers should verify fork diameter and mounting clearance for their specific model before installation.
ACROPIX Universal 39mm Fork Clamps Kit

The ACROPIX 39mm fork clamps are a billet aluminum solution designed to relocate front turn signals. Sold as a pair, the kit targets 39mm fork tubes and emphasizes a precise fit with a 1.54-inch dimension noted in the product description. The aluminum construction offers durability while remaining relatively light, which can help minimize handling changes after installation. The kit is positioned as a straightforward relocation option for riders seeking a clean aesthetic and solid mounting points for turn signals on bikes with 39mm forks.
Key considerations for this kit include material quality, finish, and symmetric installation from two clamps. Because aluminum is prone to cosmetic wear if not treated, some riders may choose to add a light protective coating or consider color-matching hardware for a cohesive look. The 39mm fit must be confirmed with the specific fork diameter and any aftermarket fork accessories. The packaging indicates a ready-to-install pair, which helps reduce searching for additional components.

The HTTMT MT299-001-BK kit offers a 41mm fork clamp alternative with a black finish that appeals to riders seeking a 39mm-class relocation option with a slightly larger diameter. This listing indicates compatibility with Harley Softail models, providing a robust mounting system for front signals. While not strictly 39mm, many riders consider it alongside 39mm options due to close fit profiles and similar mounting hardware requirements. This clamp emphasizes a sturdy build and a clean black aesthetic that blends with darker bikes or matte finishes.
Installers should verify fork diameter compatibility and clearance with other components (brake lines, fenders, or triple clamps) before mounting. The kit’s complete package is a practical choice for riders who want a ready-to-install solution that secures turn signals while maintaining a low profile. For riders updating older softail or custom builds, this 41mm option can be considered when a snug clamp that minimizes movement is needed.

The BRCOVAN 2-pack offers a versatile mounting approach, featuring solid aluminum alloy whip light mounts with 360° adjustable roll bar clamps. While primarily marketed for off-road and roll cage use, these clamps can be adapted for certain 39mm fork applications where mounting space and geometry permit. The 360° adjustability provides flexibility for aiming signals or auxiliary lights in multiple directions, which is advantageous for riders with custom handlebars or fairings. Since these clamps are not dedicated 39mm fork clamps, compatibility should be verified with the bike’s front-end architecture and desired signal position.
Riders choosing the BRCOVAN option should assess compatibility with their roll bars, tubes, and overall frame layout. The aluminum construction offers durability with weight savings, though protective coatings or finish care may help maintain the aesthetic over time. For builders prioritizing modularity and multi-purpose use, these clamps provide an adaptable mounting solution beyond strict fork relocation.
HTTMT MT299-001-BK Turn Signal Relocation Kit

The HTTMT MT299-001-BK kit focuses on 41mm fork tubes with a black finish, offering a relocation solution aligned with Harley Softail mounting conventions. While slightly larger than the 39mm options, this kit is often considered by riders who require a robust clamp for a softly upgraded front end or for models with fork sleeves that accommodate a larger clamp diameter. The kit is described as a comprehensive relocation package, designed to relocate front turn signals efficiently while maintaining a clean appearance. The dark finish helps it blend with matte or glossy black components commonly found on Harleys and similar cruisers.
Key considerations include the fit near the brake lines, fender clearance, and any aftermarket components that could interfere with a larger clamp. If a 39mm fork is the standard for a given bike but the design calls for a larger clamp, ensure adequate space and mounting points before installation. For riders upgrading from older relocations, this kit can provide a secure, low-profile mounting solution with a durable finish that complements dark aesthetic choices.
Buying Guide: Key Purchase Considerations
- Fork diameter and compatibility: Confirm whether the clamp is designed for 39mm forks, and note any models listed as 41mm or adjustable. Some listings may mention variations that still fit 39mm class forks with proper adapters.
- Material and finish: Billet aluminum and steel alloys offer strength with varying weight. Black or chrome finishes influence appearance and corrosion resistance. Consider coatings that suit riding conditions and weather exposure.
- Completeness of kit: A complete relocation kit should include all mounting hardware, spacers, and instructions. A bundled package reduces the need to source additional parts separately.
- Installation complexity: Look for clamp kits that align with your mechanical skill level. Some kits are straightforward, while others require additional drilling or bracket work, particularly on non-standard frames.
- Aesthetics and finish: Black, chrome, or satin finishes impact how the clamp blends with your bike’s overall look. Consider whether the clamp adds to or contrasts with the signals and lights you intend to install.
- Versatility: Some clamps offer additional mounting options beyond turn signals, such as mounts for auxiliary lights or whip mounts. If you plan future upgrades, modular clamps can be advantageous.
- Brand and support: Reputable brands with clear instructions and customer support simplify installation and troubleshooting. Check product reviews for real-world fit on Harley Softail and similar models.
- Maintenance and durability: Consider corrosion resistance and ease of cleaning. Stainless or coated finishes may require less upkeep in challenging riding environments.
In selecting the best 39mm turn signal clamp, readers should balance fit accuracy, build quality, and installation ease against their specific motorcycle model and riding needs. The options listed here provide a range of finishes, materials, and mounting flexibilities to support secure, reliable signal relocation on Harley Softail-inspired configurations and other bikes with 39mm-structured forks.
