Welcome to Rossier Engineering . This company first opened it's doors in 1991. Primarily a watercraft and dirt bike performance shop, we enjoyed a great deal of success during the watercraft racing boom of the 90's. As that market declined, we noticed the popularity of the burgeoning ATV racing scene. We followed the trend, and switched our operation over to 4-stroke development, concentrating on the 450 race quad segment. After brief retirement Rossier Engineering is back stronger than ever with our top performance exhaust systems that have made us a reference in the sport . Please feel free to call with any questions- (970)-391-8675
