About Us

Roseville Yamaha opened for business in April of 2003, when a 15-year veteran of the technology industry, decided to trade-in his "suit and tie" for "jeans and a polo shirt". Granite Bay Motorcycle Partners, LLC (parent company to Roseville Yamaha) was founded by Sean Coplen in December of 2002 after Sean had a poor shopping experience while looking to purchase dirt bikes for himself and his two sons. Sean soon realized that the Motorsports industry was behind the times when it came to taking great care of a retail customer. Hence, Sean set out to open a dealership that was committed to providing local Sacramento consumers with a "World Class" shopping experience. With beautiful facilities and a friendly professional staff, the effort prompted Sean to arrive at the company’s mantra…“Excellent Customer Service doesn’t have to cost more.”

Now many years later, Sean’s original motivations still drive daily operations at Roseville Yamaha. Thanks to the efforts of our amazing staff, Roseville Yamaha has received the coveted "ProYamaha Sport Specialist" award from Yamaha Motor Corporation USA for four (4) years in a row--2008, 2009, 2010 and 2011. This award is presented to only the very best Yamaha dealerships nationwide, and is awarded based on high CSI (Customer Satisfaction Index scores), high sales volume and operational Excellence. Roseville Yamaha is very proud to be a part of Yamaha Motor Corporation's "ProYamaha" program and is committed to making sure that every one of our customers experiences the very best in Customer Service and Satisfaction.

Sean Coplen, and wife Audrey, are graduates of Pepperdine University (a Christian college in Malibu, CA) and enjoy spending every spare minute with their two boys, Jake (18) and Wyatt (15). The family enjoys motorcycle rides of all kinds as well as riding Yamaha WaveRunners, boating, wakeboarding, snowboarding and mt. biking. Much of their leisure time, activities and resources are committed to several local charities, including Placer Food Bank, The Leukemia & Lymphoma Society, Toy-4-Tots, Fallen Warriors Memorial, March of Dimes, Eureka Schools Foundation, Acres of Hope and the Bayside Adventure Sports Ministry of Bayside Church in Granite Bay, CA. The Coplens reside in Granite Bay, CA—a small suburb of Sacramento.
