Surprising ergonomics
Last year, Arctic Cat engineers created an all-new chassis called Twin Spar. This high-performance architecture follows a popular trend by offering a more ergonomic and, most importantly, sportier riding position. The good news is that this ultra-modern chassis is now used by all 2-up Arctic Cat models. It's 46-percent stiffer than the old Firecat chassis thanks to new self-piercing rivets, forged shock towers and improved shock configuration. The American manufacturer therefore offers a state-of-the-art chassis for comfortable yet dynamic riding on bumpy, winding trails.

The seat, handlebar and passenger handles are easily adjustable to provide optimum positioning for all rider sizes and styles.

The Twin Spar chassis moves the rider 20 to 30 centimeters forward. As a result, the rider's weight is more centralized, which improves handling. In addition, the more ergonomic position decreases rider fatigue and provides better control. (Arctic Cat calls it the "Infinite Rider Positioning", or IRP.) The seat, handlebar and passenger handles are easily adjustable to provide optimum positioning for all rider sizes and styles, regardless of trail conditions. The raised seat allows a more natural knee bend and thus enhances comfort over long rides. In the lowest possible setting, the seat helps lower the center of gravity for improved stability in mid- to high-speed corners.

The TZ1 is extremely ergonomic. The controls are nicely laid out and even backlit for easier nighttime riding. Unlike the RS Venture's, the windshield of the TZ1 is very well designed and just tall enough to offer good protection against the elements without impeding visibility, regardless of your size.

On winding trails, the TZ1 can be pretty fast. When riding solo, you even forget that you're at the helm of a 2-up snowmobile. Sure, you have to be a little more focused to keep pace, but what a treat the TZ1 is. Active riding and synchronized leaning by the rider and passenger are musts for aggressive cornering maneuvers. Take all the time you need to get familiar with this new riding position if you hope to get the most out of it. The more you ride the TZ1, the more you like it.
