Yamaha Raptor 660 Specs and Review 2022

Yamaha Raptor 660: The 1990s were the golden age of two-strokes. At the time, Yamaha led the pack with its iconic sport quads, including the well-known Banshee 350, Blaster 200, and 4 stroke Warrior 350. The company also had stricter emission standards as well.

Yamaha Raptor 660

The Japanese manufacturer was aware that it needed to develop an improved, more powerful machine that was equally thrilling to drive as it was emission-compliant. 

In response to this requirement and the intense competitiveness among businesses, Yamaha gave birth to the Yamaha Raptor 660.

The Yamaha Raptor 660 was the first big bore sport ATV that was sold by Yamaha between 2001 and 2005. 

Also called the quad sport king the vehicle featured dual carburetors, a five-valve engine, and an aerodynamic design. 

The Raptor immediately became a popular favorite because of its power and speed.

Despite its brief existence in the market, the Raptor created such an unforgettable impression on riders that other major manufacturers were able to see the potential future of quads with big bores. 

Can-Am tried to make a stand with the Japanese firm by launching 2000 of its DS650 back in the year 2000. 

Kawasaki also followed suit by launching the KFX700 the year 2004. Honda was also following Yamaha’s trail with its TRX700XX model in 2008.

Although these four-wheelers were amazing however none of them could match the efficiency, sales, and popularity of the Raptor 660. So, what is it that makes this car so exceptional? Learn more about it here.

The Ultimate Sport Quad

In 2001 in 2001 the Yamaha Raptor 660 was the standard for ATVs with sport and it was rightly so as it was designed to replace the legendary Banshee 350. 

The Raptor used two 33-mm carburetors and a cylinder head with five valves that was the largest motor ever used on a vehicle in ATV history. 

Its impressive specifications were similar to what the name of the quad suggests in absorbing competitors and claiming its Sport ATV of the Year award.

This sports quad designed for the purpose was built from 2000 to 2004 and was released on its market over four years, beginning with the 2001 Yamaha Raptor 660. 

It has four trims with similar displacement, namely the YFM660RPmodel, YFM660RS model as well as YFM660RSET, and YFM660RT. 

The Raptor 660 begin a whole new category, it also led to the development of larger and more powerful 700-cc models. 

This is the primary reason the Raptor was only around for four years. It also gave an ancestor to one of the strongest ATVs for outdoor use ever built by the Japanese company known as it was the Yamaha Raptor 700, in 2005 (2006 model).

The Makings of a Raptor

The Makings of a Raptor

In order to create an all-terrain vehicle, Yamaha’s design team chose an engine from the dual-sport motorbike MZ Baghira. 

The German engine revolutionized the market and had the technological and power that rival ATVs were lacking. The engine was reliable and easy to work on.

came with a 100mmx bore-stroke ratio of 84mm, a liquid cooling system, single-overhead camshaft, and dual intake 33mm Mikuni carburetors.

Because of the quad’s design, Yamaha had to redesign the motor cases in order to be able to fit snugly into the frame of the vehicle. 

The radiator was located higher on the front, and right behind the handlebars. Additionally, engineers needed to build up the Raptor 660 starter clutch to be able to handle the additional weight and the traction burden.

Replacing the Crowd Favorite

One of the aspects that the Raptor was able to do well in its early days (up to the year 2005) Yamaha Raptor 660) was that it performed exceptionally well and in accordance with its output power. 

This feature quickly earned the approval of riders and proved that the machine was able to outdo its rival, the Banshee 350. 

In addition, the updated suspension and frame allowed it easier to turn in comparison to its two-stroke counterparts.

If this weren’t sufficient, Yamaha continued to develop their Raptor 660 into the Yamaha Raptor 700 which was released at the end of 2006 for the interested public. 

The engine configurations of the two models were similar but with a larger bore aluminum engine, a 686-cc power mill, an electronic fuel injection, and a more advanced bodywork. 

The frame of the Raptor was also improved by having a steel undercarriage, and an aluminum underframe. 

A new suspension design allowed for more rear-shock travel. The design team’s painstaking efforts were not in vain, as these improvements made the Yamaha Raptor 700 the best-selling ATV during a 450-cc-race-inspired-quad era.

The Upgrade King

The possibilities for customization of this machine are endless and are evident in a variety of stunning monster Raptors. 

Expertly-trained mechanics and expert outfitters have equipped the machines with a variety of Yamaha Raptor 660 parts in addition to turbo kits, modern suspensions, port cylinders, and machined heads through the many years.

This section will discuss the upgrades you can make on your four-wheeler, regardless of whether the goal is more power, faster top speed, or more riding comfort.

Recommended Mods Engine Displacement

Some riders stretch them Raptors through 686-cc and in doing this, boost the fun factor of the quad dramatically. 

Others go to the point of 727cc with a 105-mm piston hot cam for sport jet kit carburetors, the latest CDI box K&N air filters, and a non-restrictive airbox.

These changes will boost your horsepower by 20 to 20 horsepower. The Stage II jets in the carb as well as a full Yoshimura Raptor 660 exhaust, and the Hi-Pro clutch are also great options.

Stem and Handlebars

In comparison to the stock model the stem, a new one brings the bars up to give you an open and comfortable riding posture. 

Bar mounts that are rubber-damped will reduce the vibration of your arms and hands – ideal for off-roaders who frequently traverse terrains that are rocky. 

In addition, the stems and handlebars that are purchased from an aftermarket store tend to last longer and are more attractive.


Replace the semi-footrests by using Nerf bars with rubber dams that allow suspension movement. 

They also function as handlebars and stem to reduce the vibration and shock in the event of a rough landing or hit. 

There are a few variations of aluminum tubes that bolt onto strong steel mounts. In the case of Nerf bars, the only drawback is threading the nets. However, certain packages include small steel buckles, which enable threading to be done easily.

Brake Pedal

The rear brake pedal of the Raptor is often loose and loose. A clevis made of billet aluminum with a machined stainless insert and pivot will perfectly fit in the quad and reduce the slop.

There are many improvements you can make, as well as parts that can be added to the Yamaha Raptor 660 to tailor it to meet your needs. 

ATV magazines are excellent sources to help you with the future Raptor construction project. 

A bottom-end rebuild is one of the things that the majority of owners who are experienced undertake for their Raptor.
