Garage Build

2025 HONDA CRF250R


BIKE Build by Chad Braun/XPR Motorsports

The Honda CRF250R is the most improved 250 motocross bike of 2025, but we wanted to try and get a little more engine performance out of Honda’s 250 power plant, so we called Team MCR’s engine builder Chad Braun from XPR Motorsports to help us do just that. This is a starting point for some of you that may want some added meat to your new Honda as we will continue to evolve this as we save up some more dough. This build is meant to be reliable and not too expensive, so it will not break your bank. The rebuild for the engine internals are around 30-40 hours, so this isn’t a build where it’s a ticking time bomb waiting to explode all over your wallet.

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.
