Old-School New-School
Ted Boyko has been modifying engines for over 30 years, so we decided to give some old-school love to our new-school Yamaha YZ250F. We were looking for a little more lugability from our Yamaha YZ250F test machine to please a vet rider looking to race some local races against bigger 450cc machines. The stock Yamaha has. the most torque in class in stock form, but we wanted to take it a step further without using a big-bore.
We are deeply rooted in Moto—We’ve been here all our lives. Back in 1998 when we turned an underground newspaper into a shiny color magazine, it immediately changed the game with its unprecedented depth of coverage, sense of humor, and access to the sport’s biggest names. Today, our readers know they can go to Racer X Online for all the news, race results, and event coverage they need, and then enjoy even more detail and perspective in the pages of Racer X Illustrated. The mag offers a chance to learn something new on every page and stay connected with the people and personalities that shape our sport—the competitors out on the racetrack, as well as the ones behind the scenes—through our exclusive deep-dive stories and columns.
Our trademark has always been insider knowledge from the experts who are at the races and around the sport. We have long prided ourselves on our unparalleled race reporting and detailed storytelling. We go deep with the riders and teams to provide comprehensive coverage you won’t find anywhere else—all with first-class photography and design. It’s a full education in motocross past, present, and future.
