Odenthal aluminum wedge style, flush mounting, motor mount clamp. Sold As A Pair.
To determine the size required for your kart, using a caliper, measure the frame rail diameter (28mm, 30mm or 32mm). Then measure the total distance outside to outside of the two rails that the engine mounts to and subtract the rail diameter from this number.
**For example, if your frame rail diameter is 30mm and the total width of your frame rails is 120mm, subtract 30mm from 120mm and your center to center diameter is 90mm. Therefore you need two K30 clamps (30x90mm)**
