Arctic Cat Blast LT 4000: A Versatile Mid-Sized Snowmobile

The Arctic Cat Blast LT 4000 is a mid-sized snowmobile designed to offer a balance between performance and utility. Equipped with a 397cc single-cylinder, two-stroke engine, it delivers approximately 65 horsepower, providing sufficient power for various riding conditions. The engine features electronic fuel injection (EFI) for efficient fuel delivery and reliable cold starts. This model is particularly suitable for riders seeking a snowmobile that is both manageable and capable.

The Blast LT 4000's chassis is designed for agility and control. With an adjustable ski stance ranging from 37.5 to 38.5 inches, riders can tailor the handling to their preferences. The snowmobile's overall length is 128 inches, and it has a track length of 146 inches, providing stability and traction in various snow conditions. The 15-inch-wide Cobra track with 1.6-inch lugs enhances grip and floatation, making it suitable for both trail and off-trail riding. The mid-sized frame contributes to a lighter weight, facilitating easier maneuverability.

Suspension and Handling

The Blast LT 4000 features the XTRA-ACTION rear suspension system, which includes dual shocks and adjustable torsion springs. This suspension setup allows the rear skid to be locked for increased traction or unlocked for improved flotation when reversing in deep snow. The front suspension utilizes Arctic Mountain Suspension (AMS) with hydraulic twin-tube shocks, offering 7.2 inches of travel. The rear suspension provides 12.5 inches of travel, contributing to a smoother ride over uneven terrain.

The snowmobile's handling is further enhanced by its lightweight design, which allows for responsive steering and control. The combination of the suspension system and chassis design makes the Blast LT 4000 suitable for riders of varying skill levels, including those transitioning from smaller machines. The ergonomic layout, including a mountain-style seat and high windshield, provides comfort during extended rides.

Utility and Features

The Arctic Cat Blast LT 4000 is equipped with features that enhance its utility. A standard rear rack offers storage space for gear and supplies, making it practical for work-related tasks or longer excursions. The snowmobile comes with a turn-key electric start system, simplifying the starting process, especially in cold conditions. Additional features include hand and thumb warmers, a digital gauge cluster displaying speed, RPM, fuel level, and other vital information, and a halogen headlight for improved visibility.

The fuel capacity of the Blast LT 4000 is 11.7 gallons, allowing for extended rides without frequent refueling. The oil system has a capacity of 3.25 quarts, and the cooling system holds 5.0 quarts, ensuring the engine operates within optimal temperature ranges. These specifications contribute to the snowmobile's reliability and performance in various conditions.

Performance and User Experience

Riders have noted the Blast LT 4000's smooth clutch engagement and minimal vibration, attributed to its single-cylinder engine design. The EFI system provides consistent performance and eliminates the need for manual choke adjustments. The snowmobile's power delivery is responsive, making it enjoyable for recreational use while still being capable for utility purposes. Its design caters to a range of riders, from those seeking a reliable workhorse to individuals looking for a fun and manageable machine.

In summary, the Arctic Cat Blast LT 4000 offers a blend of performance, utility, and user-friendly features.
