Spears Joins Westby Racing As Official Team Partner


Tulsa, OK – May 18, 2021 – Westby Racing proudly welcomes Spears Enterprises/Spears Racing as a supporting sponsor for the team’s YZF-R3 race program competing in MotoAmerica’s Junior Cup Championship. The announcement was made by Chuck Giacchetto, team manager of Westby Racing.


About the new partnership with Westby Racing, Gregg Spears, president and founder of Spears Enterprises/Spears Racing, said, “Working with Westby Racing for the 2021 MotoAmerica Junior Cup series is an honor in itself. This is a team that has years of racing experience under their belts and a tremendous work ethic and drive to be the best. Working with, and learning from, Chuck Giacchetto gives us a great opportunity to develop our ‘small-displacement’ Yamaha R3 racing efforts and products here in the U.S. and around the world.”


Chuck commented, “For me, in regard to the ‘small-displacement’ bikes, Gregg Spears has set the bar for quite a while. When Gregg offered his expertise to our Junior Cup team, we, of course, accepted the offer with open arms. Thus far, Spears Enterprises has shown a lot of knowledge and, in particular, a ton of integrity, which is the backbone of Westby Racing. I think we stand to learn an awful lot about making the Yamaha R3 the best it can be, and I know we have excellent partners this season to give our rider Jack Roach the best possible chance to achieve his goals and run up front in the 2021 MotoAmerica Junior Cup Championship aboard the #12 JR12/Westby Racing Yamaha R3.”


Located in Manteca, California, Spears Enterprises/Spears Racing is an industry leader in the design and manufacturing of high-performance, lightweight parts for the Yamaha R3 and the Kawasaki Ninja 250/300/400. Working with specific road racers and teams, Spears has become a recognized force in MotoAmerica, AFM, CCS, and WERA. Spears Enterprises/Spears Racing has expanded its efforts to include racers and teams across the U.S., and also in Australia, Germany, Ireland, New Zealand, and the United Kingdom. Spears-equipped teams have won numerous championships all over the world.


For the Yamaha R3, and as a result of the MotoAmerica Technical Bulletin that was issued on 1/2021 and updated on 2/12/2021, Spears Enterprises/Spears Racing has created a standalone section on their Website, which provides R3 customers with quick and easy access to the specific engine components and services that are approved/authorized by MotoAmerica Technical Control for their race bikes.
