WHO WE ARE

SPEARS RACING

Gregg Spears is the President, founder and team manager of Spears Enterprises/Spears Racing.

He has 47 years of experience in the motorcycle Industry, including 14 years with the San Jose Police Department as Lead Technician. 40 of the 47 years, Spears has been the leader in motorcycle maintenance, 35 years of motorcycle roadracing support and team management with Spears Enterprises/Spears Racing. Being a dominant racing force in California, Spears Racing has earned several championships at the class, state, regional, national level and World Level and is recognized as one of the first Dynojet Power Commander tuning centers in the world. Spears graduated from high school in 1977 and went to work for the San Jose Police Department as its Lead Motorcycle Technician. It was soon apparent that his attention to detail was valuable to the industry, and decided to start working on motorcycles in his off-hours. Soon he found an overwhelming response to his talents, and in 1980 Spears Enterprises was born with $200.00 and a toolbox. Working from his carport and making house calls, Spears soon found a need for a total motorcycle repair facility.

In 1991 after leaving the San Jose Police Department, Spears Enterprises was opened in Campbell, California. Working as a sole proprietor, business was overwhelmed with customers and soon he had to hire employees to meet the demand of the workload. Long hours and relentless dedication to his customers led the business to grow, and by 1995 Spears Enterprises expanded by opening a second location. By this time the business had established itself as the leader in police motorcycle maintenance, having as many as 12 different police departments relying on Spears to meet their demands.

Working with specific roadracers, Spears Racing became a recognized force in AFM,AMA, CCS, WERA, AHRMA, LRRS and MotoAmerica competitions. Spears Racing has also expanded their efforts to include several racing venues across the U.S. and into Australia, Ireland, Germany, New Zealand, and the United Kingdom winning numerous International Championships while continuing to expand their racing support in the years to come.

In the summer of 2015 one of their Sponsors assembled a racing team called Emerald Roadracing, to run in the coveted race called “Isle Of Man TT.” With long hours and great dedication of rider and team they were able to finish 9th over all in the “lightweight/Supertwins” class on a Spears Racing powered Kawasaki ER650.

Spears Racing has shifted its business focus to manufacturing and supplying high-quality race products for smaller displacement motorcycles, offering a wide range of over 800 products, including championship-designed engine kits and purpose-built race parts. Their dedication to customers’ service and product quality seems to be a key priority.

Gregg, I wanted to thank you again for your help getting me the head gaskets so I could get my bike back together in time.  I ended up doing those gaskets, swapping to intake cams everywhere and a full Yosh exhaust.  The bike is a rocket ship now!

Gregg When I called to tell you about my mysterious engine stalling you were quick to point out that you had a plug’n’play side stand lockout kit for just that situation. As always it arrived in a couple of days and went on in a jiffy. One less thing to worry about while on the track. I can’t tell you how much I appreciate the support that you are providing to my race program, with both your products and your knowledge - you rock!
