The original design of utility ATVs was offered from 1996 to 2004 and featured single cylinder liquid or air cooled motors from 250 to 500cc's, and all of a common design. This Arctic Cat-designed motor was manufactured by Suzuki and featured a 2V SOHC design with hemispherical combustion chambers. Manual and CVT automatic transmissions were offered. A 650V2 V-twin engine option borrowed from the Kawasaki Prairie was also offered starting in 2003. A major redesign of the platform was launched in 2005. With the new redesign came new body work, electronics, rear mounted gas tank and a standard front locking diff, though the chassis in general remained largely unchanged. A new high performance engine platform also debuted in the 650H1. This H1 platform was a direct evolution of the previous suzuki manufactured engines with many parts being interchangeable, but was now manufactured by Arctic Cat in the US. A 700EFI model was also offered which used an engine and transmission combo borrowed from the Suzuki King Quad model. This is a 4V dohc design with no relation to the H1 engine platform. This was replaced with the 700H1 which was a higher displacement version of the 650H1 with fuel injection added. A 1000cc H2 V-twin engine, was also made available. Arctic Cat utility ATV's are primarily designed and marketed toward utilitarian uses such as farm work and hunting. Compared to other ATVs, they offer very high ground clearance, low gear ratios for towing, and large steel racks for hauling large loads, and large fuel tanks for extended range. The high ground clearance and locking differentials make them particularly adept off road. They also offer 2 up models, and the TBX model which features a large dump box and high payload capacity, and a Mud Pro model which features factory air snorkels to allow it to drive nearly submerged, larger mud tires, and stronger driveline components.
