Factory Connection® was founded by Mike McAandrews in 1988. Mike was a race mechanic and suspension technician for Kawasaki in the 80’s. During his tenure at Kawasaki, he won several championships with Jeff Ward and also spun wrenches for Ron Lechien. The relationship with Kawasaki and KYB is where the name originated from. The original Factory Connection logo was drawn freehand in pencil by David Bailey on a napkin.
