Both the ZR 9000 Thundercat and the Yamaha SRX LE are among the fastest snowmobiles and are powered by Yamaha's turbocharged 980cc 200-horsepower engine. However, the ZR Thundercat has unique features like the Arctic Cat drive system, which includes the TEAM Rapid Reaction BOSS driven clutch and the Rapid Response II drive clutch. It also uses a covert hydraulic master cylinder for its brakes and offers two color choices for customization.
