Yamaha RX Warrior Specs and Review [Video]


The 2004-2005 Yamaha RX Warrior was a crossover version of the extremely popular Yamaha RX-1 performance sled. These models shared the same engine and Delta Box chassis, but the Warrior featured a longer track and a different skid. Therefore, it was more stable but slightly slower than the trail-intended RX-1.

Yamaha RX Warrior Review

The Yamaha RX-1 Family

Yamaha entered the 4-stroke snowmobile market in 2003 with the introduction of the RX-1.

This high-performance trail snowmobile replaced the top-of-the-line 2-stroke SRX 700 triple.

The RX-1 family consisted of three models in the 2003 season, the base RX-1 (without a reverse), the more featured RX-1 ER, and the RX-1 Mountain.

As the name suggests, the latter was designed for mountain riding, so it came standard with a 151” track and a reverse system. In contrast, its trail-intended counterparts featured a short 121” track.

In 2004, Yamaha expanded the RX-1 series with a crossover version, and the Warrior was born.

The official name of this model was Yamaha RX Warrior (RXW10), but it was often referred to as RX-1 Warrior.

What was the difference between this sled and the rest of the RX line?

In a nutshell, the RX Warrior came standard with a 136” track and a reverse system. It also featured a ProAction rear suspension, which was replaced by the Pro Mountain rear suspension in 2005.

In contrast, trail-intended RX models got the new Monoshock skid that same year.

Aside from these differences, Yamaha RX-1 snowmobiles were identical.

This series was manufactured until 2005 and replaced by the Apex in 2006.

Yamaha RX Warrior Review

It’s safe to say that the Yamaha RX Warrior was one of the most innovative snowmobiles during the early 2000s.

It was not only part of the first 4-stroke Yamaha sled series, but also packed many innovative features, including:

  • Delta Box chassis
  • Dual rear exit exhaust
  • Independent double-wishbone front suspension
  • Pro-Action rear suspension with adjustable gas shock
  • Hydraulic disk brakes
  • Advanced LCD gauge (speedometer, tachometer, trip meter, odometer, fuel gauge)
  • Hand and thumb warmers
  • Easy-pull throttle lever
  • Electric start
  • Reverse
  • And more

However, the most exciting feature of the Yamaha RX Warrior was its revolutionary 4-stroke engine. This liquid-cooled, 4-stroke, 998cc, DOHC, Inline-4 power mill delivered a jaw-dropping 145hp.

Interestingly, this unit was derived from the YZF-R1 sport bike.

Thanks to this powerful engine, the Yamaha RX Warrior topped out at 120mph on the speedo, which was more likely 105-107 mph on GPS.

Compared to competitor 2-stroke 800 snowmobiles, it was significantly more powerful and produced 65% more low-end torque.

The fuel capacity of the sled was 10.4 US gallons, which ensured roughly 200 miles of riding between refills.

Yamaha RX Warrior Problems

Although the Warrior was a revolutionary machine in many ways, it had some problems, including:

Heavy weight: There’s no question that the biggest problem of the RX Warrior (and the entire RX class in general) was its extreme weight of 582 pounds. Due to this massive weight, the sled newer became a successful crossover sled. Instead, it was commonly used on hard-packed trails and lakes.

Design issues: The Warrior was also often criticized for its narrow steep footwells and very low handlebars, which made it difficult to ride in a standing position.

Shock adjuster cable issues: The factory shock adjuster cable on this sled was quite weak and prone to breaking. The manufacturer launched a service kit to solve this issue that had a new cable and cover.

Difficult double riding: Let’s face it, the RX Warrior was designed to be a one-rider sled. Carrying a passenger on this machine was neither comfortable nor safe since the extra weight translated into various handling issues.

Lack of “Braaaap”: Due to its 4-stroke engine, the Warrior lacked the distinctive “Braaap” 2-stroke exhaust music.
