ZXHEXADRONE Engine Motor Mount Plate for Predator 420cc/670cc — Adjustable Black Iron Weldment, Pre-Drilled Bolt Pattern

ZXHEXADRONE’s Engine Motor Mount Plate is a heavy-duty, adjustable iron weldment designed to secure Predator 420cc and 670cc engines (and compatible bolt-pattern engines) to go-karts, mini motorcycles, and similar outdoor power-sport frames.

Whether you’re building a weekend kart, swapping a mini bike motor, or upgrading an outdoor project, a reliable mount keeps the engine aligned, stable, and safe. This mount plate is finished in a durable black coating and machined to match common Predator bolt patterns, letting you bolt the engine to the chassis without complex fabrication. It’s offered in two displacement fits—420cc and 670cc—so you can pick the plate that matches your engine family and minimize drilling or adapter use.

How does this mount plate simplify engine installation?

The plate’s straightforward shape and pre-drilled bolt pattern reduce layout time and fabrication work. Installers can align the engine directly to the plate, secure it with bolts, then attach the plate to the frame using existing mounting points or adjustable brackets.

• Pre-drilled bolt pattern matched to Predator 420cc and 670cc engines
• Single-piece iron construction for easy alignment
• Black finish resists surface wear during handling
• Minimal welding or modification needed in most builds

What makes this mount plate durable enough for outdoor power-sport use?

Built from sturdy iron plate and finished in black, the weldment resists bending and stands up to vibration common in kart and mini-bike applications. Quality control checks during production help ensure consistent hole placement and plate flatness, which matter for long-term stability.

• Thick iron construction resists deformation under load
• Robust welds at attachment points for lasting strength
• Protective black coating helps prevent surface corrosion
• Inspected units for accurate bolt alignment and fit

Will this plate work with engines other than Predator models?

The plate is made for Predator 420cc and 670cc bolt patterns, but it often fits other engines that share the same hole spacing. If your motor matches those dimensions, the plate can serve as a universal base with little or no modification.

• Check bolt-hole spacing against your engine before purchase
• Compatible with engines using the same mounting pattern
• May require shims or minor bracket adjustments for perfect alignment
• Designed to reduce the need for custom-fabricated adapters

What installation and safety steps should I follow?

Install the plate in a well-ventilated, stable workspace using appropriate tools and fasteners. Secure the engine to the plate with graded bolts, torque to manufacturer specifications, and verify alignment before first run to prevent undue stress on mounts and driveline components.

• Use proper-grade mounting bolts and torque specs
• Work in a ventilated area, especially when welding or grinding
• Check alignment and clearances for chain, belt, and exhaust
• Re-inspect mounts and fasteners after initial runs

Who is this for? Builders, hobbyists, and small-fabrication shops working on go-karts, mini motorcycles, or compact outdoor power machines who need a ready-made, robust engine mounting solution will find this plate useful. It’s especially suited to projects using Predator 420cc or 670cc engines—or any motor that shares those bolt-pattern dimensions—and for anyone who wants a strong, easy-to-install mount without custom fabrication. Avoid using it beyond its rated engine classes and always follow safe installation practices.
