MTJSWXSY 20ft 1/4 Inch High Temperature Braided Loom
This braided, self-wrapping loom is designed for wiring runs where heat buildup is a concern. It uses a heat-retardant PET polyethylene material with heat resistance up to 302 degrees F, helping extend cable life in hot engine bays. Best for lightweight harnesses and tight routing in motorcycles where space is at a premium.
Best for: riders on a budget who need compact protection for short runs or fine wire bundles in hot zones.
Why selected: The 25% overlap and self-closing wrap simplify installation and reduce the need for extra tape or fasteners, making it a practical upgrade for clean, secure harness management.
Caution: Very large-diameter bundles may require the 1/2″ or larger sizes for full coverage; 1/4″ fits smaller harnesses best.
BEIVOBY 2 Rolls High Temp Wire Harness Tape
This OEM-grade automotive cloth tape handles harsh temperatures from -40℉ to 250℉ and provides strong damping and soundproofing for wiring looms. The dense, extra-sticky adhesive makes bundling hard-to-reach cables easier, while its flexible fabric resists cracking over time.
Best for: riders who need OEM-like protection and reliable vibration and noise dampening in engine bays or dashboards.
Why selected: The combination of high heat tolerance and robust adhesive helps keep wiring tidy in demanding environments.
Caution: Cloth tape can accumulate dirt over time; periodic re-taping may be necessary in dusty riding conditions.
CrocSee 25ft 1″ Split Loom With Installation Tool
Thick, flame-retardant polypropylene split loom provides robust protection with a wide inner diameter ideal for larger bundles. The included installation tool makes it easier to feed wires through, saving time on installation in motorcycles with cramped wiring channels.
Best for: riders replacing or protecting thicker harnesses and those who want an included tool to speed setup.
Why selected: Its broad 1″ diameter accommodates larger bundles while remaining flexible enough for curved routing.
Caution: Weight and stiffness may be less ideal for ultra-tight bends; consider smaller diameters if space is extremely limited.
MTJSWXSY 20ft 1/2 Inch High Temperature Braided Loom
A larger-diameter version of the 1/4″ loom, this 1/2″ braided loom offers enhanced coverage and security for heavier harnesses. The same heat-resistance and abrasion protection apply, with improved overlap for continuous protection around bends and long runs.
Best for: riders with dense electrical harnesses, higher heat exposure, or longer routing paths needing stronger protection.
Why selected: The 25% overlap design helps prevent braid separation and ensures consistent coverage through complex wiring routes.
Caution: The larger size requires more space and might not fit every routing path in compact builds.
wevsuipo 1/2″ x 125 Ft Assorted Kit
This assortment provides multiple sizes in one kit, giving builders flexibility for various sections of a motorcycle harness. The polypropylene material provides good heat and abrasion resistance, and the included installation tools and zip ties facilitate easier setup across different projects.
Best for: DIY enthusiasts and builders who need a complete set for multiple wire routes on a motorcycle.
Why selected: The kit covers common sizes (including 1/2″ for thicker bundles) and includes practical installation aids, making it a versatile choice for diverse builds.
Caution: Bulk packs can lead to unused lengths if only specific diameters are needed for a single project.
Buying Guide: Key Considerations For Motorcycle Wiring”
Durability, heat resistance, and ease of installation should guide your choice. Consider these questions:
- What is the typical bundle diameter in your harness, and which loom sizes best match it?
- Do you need flame retardant properties for engine compartments or under-hood areas?
- Is self-wrapping or taped installation more suitable for your wiring route?
- Will you be routing through tight bends, requiring flexible material and good overlap?
- Are spare installation tools or accessories (like a loom insertion tool) beneficial for your project?

Frequently Asked Questions
- What loom size should I choose for a motorcycle harness?
Choose a size that matches the largest bundle in the run, allowing some extra clearance for routing bends. - Are heat-resistant looms necessary for under-hood wiring?
Yes. Engine compartments experience higher temperatures, so heat-tolerant looms extend cable life and reduce insulation damage. - Is a flame-retardant loom necessary for motorcycles?
It’s beneficial in high-heat areas or near exhaust components to reduce fire risk and withstand heat exposure. - Can I install loom without specialized tools?
Many kits include installation aids; for tight routes, a loom insertion tool speeds feeding and reduces damage to wires. - Should I mix loom types on a single motorcycle?
Yes, use smaller diameters for tight sections and larger sizes where bundles are thicker or longer spans exist. - Do these looms improve vibration damping?
Some fabric tapes provide vibration dampening, while braided and split loom designs primarily protect against abrasion and heat.
