What you get

The ProStar S4 Titan Ultimate runs a 998cc liquid-cooled twin with sequential port injection and H-L-N-R transmission. Four riders fit the bench seats, and the BackTrak20 rear suspension handles rough terrain without complaint. High clearance IFS front, FOX QS3 rear shocks, and a 20-inch track width keep you planted in powder and crud. Fuel capacity sits at 12.6 gallons. Moon Motorsports stocks the S4 Titan Ultimate in Monticello. See us for pricing and availability.
