4-Cycle Motor Mount by Odenthal for Briggs 206, World Formula, and more! This EZ-Set motor mount is one of our favorite picks for 4-cycle racing, and features an 8-degree incline to the base plate that mounts to the motor. With multiple off-set options, a base plate and slider mechanism, and laser-etched logos and markings, Odenthal's motor mount rises above the rest to offer an engine mount to meet your needs and mate well with a variety of chassis. The top plate of this motor mount is angled at 8 degrees, a common angle for Briggs 206 and other 4-cycle motors.
Odenthal has revised their 4-cycle motor mount several times over the years. The EZ-set mount is the result - now with the "Euro-Style" low profile base! With strong clamps, a base plate, and top plate all included in the mount system, the EZ-set system makes adjusting your chain tension and motor position super simple. This means this mount is a life time investment: use it on multiple chassis, for many years to come!
With more mounting holes available on this motor mount than any other on the market, Odenthal is serious about adjustment - they want you to have the ultimate in customization and fit options! Each M8 x 1.25 threaded hole is designed to fit with the included motor mount studs, each of which has a 4mm allen-key top to it, to make installation and removal a breeze.
Each motor mount comes with all hardware needed to mount your engine to the motor mount, including:
- Odenthal EZ-Set Top Plate, Base Plate, and (2) Clamps (note - non-clamp option available)
- (4) M10 Threaded bolts
- (2) M10 washers (for EZ-Set slider mechanism)
- (4) M6 Threaded Motor Mount Studs (w/4mm Allen Head)
- (4) M6 Metal Lock Nuts (to clamp down on motor once mounted on engine mount)
- Odenthal Sticker - now in Chrome!
Finding the Right Motor Mount for Your Chassis
Finding the right motor mount and clamp configuration for your chassis can be daunting. Fortunately, we are here to make it easier for you! Odenthal's motor mounts come with several clamp and base-plate options, which means that the ultimate fit for your chassis is perfect, every time. However, a little measurement is necessary to ensure things fit this way!
Consider the following example:
To find the right motor mount for your chassis, examine the area of your kart chassis that is used for fixation of your motor mount and engine. For most karts, this is on the driver's right, near the rear axle, and can be found by looking for a portion of the frame that features two parallel tubes.
The dimensions of your motor mount is directly related to both the spacing between your motor mount frame rails, and the outer diameter of the chassis tubing itself:
- "K" type spacing means that center-center between these tubes is 90.0mm. This is more common on many CRG-derived chassis.
- "I" type spacing means that center-center between these tubes is 90.0mm. This is a more common spacing on European karts, but be sure to double check your chassis!
To determine which frame rail spacing your kart has, take two measurements:
- Measure the outer-outer distance of the frame rails. That is to say, from the outer edge of one frame rail, to the outer edge of the other frame rail. Typically, this will be a measurement between 118mm and 124mm.
- Measure the outer diameter of either frame rail. Most commonly, karts utilize 28.0, 30.0, or 32.0mm frame rail tubes.
Now, subtract your frame rail diameter from the outer-outer measurement, and you have your frame rail spacing! Remember, this should be a value of 90.0mm or 92.0mm.
Note on Measuring: For best results, Point Karting recommends using a set of digital calipers, with a range of motion of at least 130.0mm.
