Description

680-00 Billet Aluminum Flip-Style Motor Mount – International Rail (7°/15°)


The 680-00 SK Billet Aluminum Flip-Style Motor Mount is one of the most trusted and widely used engine mounts for international rail go-karts. Designed for performance and adjustability, this dual-degree mount allows you to choose between a 7-degree or 15-degree engine angle simply by flipping the top plate—giving racers more control over engine tuning and chassis setup.


Crafted from precision-machined billet aluminum and anodized black for corrosion resistance and style, this mount is compatible with popular small engine platforms including:

  • Honda GX160-GX200
  • Clone/Predator 212cc
  • Briggs Raptor & Briggs Animal
  • Other engines with similar bolt patterns

This mount is designed to fit most international rail-type chassis and includes hardware for easy installation. However, due to variation in rail spacing and tube diameter, fitment is not guaranteed for all karts—please verify your chassis dimensions before purchase.


Key Features:

  • Dual-angle mount: Flip design supports both 7° and 15° setups
  • Material: CNC-machined billet aluminum, black anodized
  • Fits engines: 160cc–212cc class engines (Honda, Clone, Predator, Briggs)
  • Chassis compatibility: Designed for International Rail karts (3.625" / 92mm center-to-center)
  • Includes mounting hardware


Fitment Notice:

Not all "American-made" chassis use the American rail pattern. Similarly, not all foreign-made karts use international rails. Here’s how to check your rail type:

  • International Rail spacing: 3-5/8" (3.625") or 92mm center-to-center
  • American Rail spacing: 2-7/8" (2.875") center-to-center
  • Rail tube diameters vary:
    • American: 1-1/8" or 1-1/4"
    • European: 28mm, 30mm, or 32mm


Some mounts fit 1-1/8" and 30mm but may not fit 1-1/4" or 32mm tubing. Always verify rail spacing and diameter with a dial caliper before ordering.


Some chassis manufacturers use proprietary rail patterns that don’t match standard International or American spacing. In these cases, only the manufacturer's specific mount will fit.

FAQ

Q1: What engines will this motor mount fit?

It fits most small engines with standard bolt patterns, including:

  • Honda GX160 / GX200
  • Clone / Predator 212cc
  • Briggs Raptor & Animal
  • Other similar 160–212cc class engines


Q2: What does “flip-style” mean?

The flip-style design allows the mount to be used at two engine angles:

  • 7-degree for standard setups
  • 15-degree for more aggressive engine tilt or improved carburetor clearance
    You simply rotate the top plate to switch between the two.


Q3: How do I know if it fits my chassis?

Measure your rail spacing and diameter:

  • International Rail spacing: 3-5/8" (3.625") / 92mm center-to-center
  • Rail tube diameters vary: common sizes are 1-1/8", 1-1/4", 28mm, 30mm, or 32mm

Some mounts fit only specific diameters. Use a dial caliper to verify your rail size before ordering.


Q4: Will this fit American-made chassis?

Not always. Many American chassis use International Rail spacing, but some still use American spacing (2-7/8") or proprietary mount patterns. Always confirm your chassis rail measurements first.


Q5: Does the kit include hardware?

Yes, the mount comes with mounting hardware included for installation.


Q6: What if my chassis has a proprietary mounting pattern?

Some brands use unique spacing that doesn't match either International or American rail standards. In these cases, you'll need a brand-specific engine mount.
