Lock and load your RZR RS1 and get ready for some serious kick! The RZR RS1 is a great machine, but Polaris left a ton of room for improvement on any year machine. This simple kit is the best way to wake up your RS1 as it comes with our proven ECU tunes which are loaded via the PV3 ECU tuner. The tunes add some amazing horsepower from low end to high end RPM's, and really give your machine that "snap" you're looking for. The clutching complimentthe tuning perfectly by better transferring the power to the wheels and ridding yourself of the very lazy factory clutching setup.
Torsion Anti-Chatter Kit: Upgrades to a complete secondary converted to a Torsion style spring and helix. The main benefit is better belt grip with the Torsion spring that gains rate as it shifts. Constant pressure against the helix buttons for less annoying secondary clutch chatter which also extends the life of the buttons. You'll also notice smoother engagement which is excellent for those crawling. Secondary bushing comes peened over to prevent walking out. The Torsion kit slightly limits top speed and should be used with the AA primary clutch limiter. 80-85 MPH top speed for most models.
The Level 1 tune is a huge increase and is meant to be ran with the stock exhaust. This is seriously worth every penny! You are looking at a 6-7 RWHP gain with the tune and 8-9 RWHP when used with our S3 clutch kit. Peak power is excellent with this setup but the bottom end gained might be even better! Peak power is 8600-8800 RPM 55 MPH.
The level 2 tune has all the same benefits as level 1, with increased fueling for a slip-on or full exhaust system. Together with a tune and exhaust you can see 8-10 RWHP gains, and 2-3 more RWHP when used with our S3 clutch kit! Peak Power is 8600-8800 RPM 55 MPH.
The Level 3 tune has all the same benefits as Level 2 but with increased fueling for performance cams. Please note that with large lift cams you typically sacrifice idle quality.
The Level 4 tune has all the same benefits but with increased fueling for most big bore kits.
