The Yamaha Raptor 350 Has Been Around

Originally dropping in 2004, this mid-bore quad came out the gates as a strong competitor in the market for top speed and handling. From 2004 until 2013, Yamaha produced the sport and leisure ATV known as the Raptor 350. It had excellent handling, low to mid-range power, and racy looks. This four-wheeler was made to be enjoyable to ride and ideal for off-road tracks.

During its lifespan, This sporty 4×4 remained unrivaled in terms of performance and design. The Raptor 350 had a fruitful 10-year production run until being discontinued when the Raptor 250 gained popularity.

The Yamaha Raptor 350’s design draws inspiration from two legendary vehicles, the 2001 660R Raptor and the 2004 YFZ450. It resembles big-bore four-wheelers, which predominated the ATV market a few decades ago, but in a smaller, more manageable size.

The low-lying seat provides comfortable sport riding ergonomics while allowing riders to still enjoy operating a powerful ATV. To ensure a secure grip and the comfort of the rider, extra wide, 45mm footpegs were directly taken from the YFZ450.

The Yamaha Raptor 350 In Action

Raptor owners adore the vehicle’s braking technology, which provides dependable stopping ability on a variety of road conditions. Through a handy shift lever, the quad can also shift into reverse from any gear.

Because of the engine’s high snorkel-type intake, airflow is never constrained or insufficient. Rear-wheel travel from piggyback reservoir shocks with five-way adjustable preload is respectable, resulting in consistent performance during challenging sport riding.

Other appealing characteristics include a handlebar-mounted choke lever that is simple to use, a six-speed transmission, an upgrade-friendly SOHC architecture, and low-profile tires with lots of traction. The Raptor was also among the first vehicles to include white plastics, which made it the ideal canvas for adding graphics and decal kits to make the quad uniquely yours. 

The Yamaha Raptor 350 Cost

The Raptor’s base model can cost between $4,999 and $5,599, depending on the model year, trim, and package options. The retail price of your chosen model would increase by at least $700 if you included a full complement of extras, such as GYTR aluminum engine/front A-arm/swingarm skid plates, front grasp bars, antennas, hour meters, tachometers, etc.

The model years of the auction postings are typically from 2004 to 2007. Their prices range from $1,700 to $5,460. The majority of the items up for bid are either modified or nearly mint. 

Models from 2008 and recent years, which normally cost $2,500 to $4,000, are seldom ever seen on auction and trading websites. Regardless of the year of construction, the white and gray trim appears to retain its worth well.
