Probably the most popular big-inch sled of the era was the Indy powered by a carbureted cc piston port triple. This somewhat unsophisticated 2-stroke made turbine-like power and, in combination with Polaris P clutching, delivered performance way beyond expectations. When Polaris announced its intention to build the same sled with electronic fuel injection, the naysayers were upset, probably because they felt it meant you could no longer make engine modifications to jack horsepower and performance beyond stock. The naysaying continued until the day after the first person rode an RXL. The difference between it and the carbed was profound. There was no initial fatness on throttle tip-in; smooth, stumble-free acceleration every time and the best part: The RXL, at least in bone stock form, was noticeably faster!

Although electronic fuel injection had begun to show up as an aftermarket add-on for snowmobiles, Polaris became the first snowmobile manufacturer to produce an actual production sled with EFI technology. Fitted to the top of the line Indy performance triple, the fuel system quickly appeared on the popular Indy twin. Today every snowmobile manufacturer offers fuel injection systems. But in Polaris claimed leadership with EFI. Of course, at the end of the decade a Colorado jury would say the Polaris system showed an all-too clear resemblance to a system brought to Polaris for examination in the summer of by Injection Research Specialists. The end result would be a multi-million dollar judgment in favor of Injection Research Specialists. To keep the cc triple cool, Polaris used aluminum extrusions mounted under the runningboard. Based on the carbureted that conquered the Formula III World Championship in , the fuel-injected version was said to add more performance and even increase fuel efficiency up to 10 percent. The fuel injected motor differed from the carbureted version. The cylinders and heads were unique to the EFI triple, helping the engine breathe easier and boosting power. The intake consisted of three 46mm butterfly throttle bodies. For the rider, RXL throttle action was quick due to its light pull. The computerized intake made overall performance noticeably smoother as the system read atmospheric pressure and ambient temperatures instantly and immediately calibrated the system to any changes. The computer also set a rev limit to keep the engine from over revving.

It sure woke up the sled and lightened up the front end a bit.

Now the really bad part. The sled came with a freshly built engine top to bottom and a spare engine for parts if need be. Polaris also developed a liquid-cooled hydraulic disc brake to keep the braking system on its high performance models from overheating. Deals Forum.
