SANAR Longtail Mud Motor Frame

The SANAR frame component is designed for long-tail/mud motor configurations that rely on a compact frame element and an oil-seal interface. Best for small- to mid-sized surface-drive setups and spare parts integration, this item suits buyers who want a straightforward seal-compatible frame piece for maintenance and replacement. A caution: verify compatibility with your specific drive shaft model before ordering to avoid fit issues.
15HP Mud Motor Kit Not Included

Although listed as a kit without the motor, this accessory is relevant for buyers assembling a lighter mud-motor setup where the frame and supporting hardware are prioritized first. Best for hobbyists building a compact mud motor project that will source a separate 15HP unit later. Caution: no motor is included, so plan for separate motor procurement and matching mounting hardware.
MT09 Tail Box Cover Short Tail Kit

Best for riders needing rear protection and a clean tail profile, this short-tail tail-box cover helps shield wiring and mounting points from vibration and minor debris. It is especially suitable for MT-09 model builds and similar rear-module configurations. Limitation: designed for specific motorcycle tail geometries; confirm fitment with your bike’s rear section before purchasing.
Duke 390/250 Short Tail License Rack

Selected for its compact, sturdy design, this license rack serves as a short-tail solution that can double as a fender eliminator. Best for Duke 390/250 and compatible models where a minimal rear-mount device is preferred. A caveat: aluminum construction offers strength, but check for any clearance conflicts with exhaust or rear suspension components.
lekiliky License Plate Bracket

Best for riders seeking a scratch-resistant, rustproof license plate holder with foldable functionality. The solid iron construction provides durability, and the foldable design helps navigate rough roads or tight turns. Limitation: heavier than plastic options, so ensure mounting points can support the added weight on smaller bikes.
KAGEFUNE XSR900/900 Range License Frame

Best for riders with MT- and sport-bike setups needing a robust, brand-new license frame and fender eliminator use. Made from thickened aluminum alloy, it offers weather resistance and long service life. Caution: ensure compatibility with your specific bike model year and tail design to avoid interference with taillight wiring or exhaust routing.
Buying Guide
What should I consider for a short-tail mud motor frame?
Compatibility with your drive system is critical. Check shaft alignment, mounting hole patterns, and vibration isolation. Consider whether you need a full rear cover, a lightweight license rack, or a frame component that doubles as mud protection.
Material and durability
Common materials include aluminum alloy and iron. Aluminum offers light weight and corrosion resistance but may be less forgiving in heavy impacts. Iron is robust and durable but heavier. Choose based on your riding conditions and mounting constraints.
Protection vs. weight
Tail covers and racks provide protection for wiring and license components but add weight. If you ride in rough terrain, prioritize protective design; for road-focused setups, lighter frames may improve handling.
Installation considerations
Look for easy installation with clear mounting points and fasteners. Some products are designed for specific models; verify fitment before purchase to avoid clearance or interference issues with exhausts, tires, or suspension.
Maintenance and weather resistance
Scratch-resistant surfaces and rust-proof coatings extend life in wet or muddy conditions. Factor in the climate where you ride and whether you’ll clean and dry components after use to maximize longevity.
Multi-model compatibility
Some license racks and frames are marketed for multiple models. If you own more than one machine, those options can simplify upgrades. Always confirm model-year compatibility and hardware requirements.
Practical quick FAQ
- What is a short-tail mud motor frame best used for? — It supports rear-mounted components on compact mud-motor and short-tail setups, providing mounting points and protection.
- Do these frames fit multiple bike models? — Many are designed for several models; check model-year and mounting patterns to ensure a proper fit.
- Is aluminum or iron better for a license rack? — Aluminum is lighter and corrosion-resistant; iron is tougher but heavier. Choose based on ride conditions and weight limits.
- Should I choose a tail box cover or a license rack? — If you need rear protection and wiring shielding, a tail box cover helps; for mounting a license plate, a rack or frame is more suitable.
- Are these components easy to install for a beginner? — Some are designed for straightforward installation, but verify the required tools and model-specific guidance before starting.
- Do these parts affect ride height or handling? — Generally minimal, but added weight and mounting location can slightly influence handling; plan accordingly.
