Yerf-Dog is the motor drive division of FF Acquisition Corp (dba Flexible Flyer). FFA is a leading manufacturer and distributor of value engineered consumer products with 3 operating facilities containing in excess of 1 million square feet of operations.

In 2005 Yerf-Dog the motor drive division of FF Acquisition Corp (dba Flexible Flyer), closed its operation and manufacturing. At that time their parts and inventory were auctioned off. 

BMI Karts purchased the remaining parts. BMI is not Yerf-Dog (or Flexible Flyer) and has no affiliation with them. BMI is commited to supplying customers with quality OEM replacement parts at great pricing.
