Walsh Race Craft has been developing and manufacturing top level ATV suspension components since 1997, what most people don’t know is that Walsh Race Craft has also been involved in engine performance, maintenance and development for just as long. Though Walsh Race Craft had been cooperative with other engine performance companies for many years in the past, we took on the responsibility of our own engine program in 2008 with Jeremy Lawson on a TRX-450R in the professional motocross ranks, where we finished second place in AMA GNC racing. We publicly released our engine expertise in 2009, after a stellar year with Cody Gibson on the Walsh Race Craft/Monster Energy/Kawasaki Team. Cody became the first person to win both Pro-Am championships in a single season, as well as winning the most races, leading the most laps and pulling the most holeshots of any rider in the two classes. Since going public with the engine program, we have had a very pleasing success rating, we have not stopped offering the same phenomenal service that we do with our own race equipment and have continued to search for and make improvements in nearly every aspect of engine performance. Their search for continued improvements is exactly what led them to Star Racing for their cylinder head air flow research and development needs. They had started testing Star Racing cylinder heads in 2011 and have been very pleased with their performance and professional quality. In order to keep their engine program on the cutting edge of technological breakthroughs, Walsh Race Craft has developed a partnership with Star Racing for cylinder head air flow research and development. Both Walsh Race Craft and Star Racing are excited to announce that this high level of engine performance is now available to you! Star Racing may be a new name in the motocross world, but we are not new to motorsports and cutting-edge performance technology. With Star Racing's 25+ years of 4-stroke technology and employees with over 60+ years of combined experience within the sport, they are looking to climb to the top of the podium in this venue while helping you get there too! We have numerous local amateur and two pros already under our tent helping prove our metal, and we're looking to grow with you.
