2006 Yamaha Sports FZ1/FZ1 Fazer 1,000cc naked model mounts high performance engine inherited from the YZF-R1 Yamaha Sports "FZ1" and "FZ1 Fazer"

Sept. 29, 2005

Yamaha Motor Co., Ltd. exhibits the big-displacement "naked" model FZ1 mounted with a high-performance liquid-cooled 4-stroke, DOHC, in-line 4-cylinder 1,000cc engine, which is a direct descendant of the YZF-R1 engine, and the FZ1 Fazer with semi-cowling at the Paris Show (Mondial du Deux Roues 2005) from October 1. The models go on sale first in Europe and then in North America in late 2005.

The focus of the development of this model "FZ1" was building a "real emotional roadster," so the same type of engine as on the 2005 YZF-R1 was mounted on a newly designed lightweight aluminum frame, achieving a 15 kilogram weight reduction compared to the present "FZS1000 FAZER." The synergy created by optimization of the engine specifications realizes superb riding performance on ordinary roads that allows the rider to enjoy this new big-displacement naked machine as if it were "an extension of the rider's body."
In addition, the "FZ1 Fazer" the same model as above with a semi-cowling as standard equipment, was designed to be a "1,000cc with a high-level balance of Sports & All-rounder qualities."

Market background and product summary

The "FZS1000 FAZER," which has been on sale since 2001, is popular among a wide range of users as the standard model of the naked 1,000cc category. Some of the main reasons for its popularity are its "powerful and highly flexible engine performance," "comfortable long-range cruising performance," and "superb tandem riding performance in longer riding." (In-house research)
Present annual demand in Europe for the liter class is standing at around 83,000 units; some 57 percent of them are in the liter naked category, with slight growth being seen. In the European market, more users are turning away from pure supersport models and rediscovering the value in performance in the actual-use speed range. Calls are increasingly heard for even higher performance and new value in the 1,000cc sports class than before.
Under these circumstances, the "FZ1" and the "FZ1 Fazer" were developed to be the successors to the present model "FZS1000 FAZER," and at the same time, to utilize the high performance of a supersports engine to achieve an emotional riding experience in the practical-use speed range.
The latest technology has been utilized throughout the naked "FZ1," realizing the concept of a model with "light, athletic handling and flexible, easy-to-use running performance." The "FZ1 Fazer" realizes a "1,000cc with a high-level balance of Sports & All-rounder qualities."

Main modifications and characteristics


1) Liquid-cooled DOHC in-line four-cylinder, 5-valve engine with fuel injection aimed at optimum performance in the practical-use range
The power unit mounted is newly developed, with the 2005 YZF-R1 liquid-cooled, 4-stroke engine as its base, to realize an "emotional" performance feeling and ease of use.
Main specifications and parts employed are identical to the YZF-R1: 77 x 53.6mm bore x stroke, compact combustion chamber, crankcase, piston, directly plated cylinder (closed-deck type), cylinder head, forged piston, and FS con-rods. On the other hand, changes have been made in order to realize a better feeling of power and ease of use in the practical-use range: the compression ratio has been changed (12.3 : 1 to 11.5 : 1), cam profile has been modified, and crank inertial mass has been increased 40 percent to achieve both good power and smooth handling on secondary roads and in the practical-use speed range. Maximum power output of 150PS is achieved at 11,000rpm.

2) Fuel injection with sub-throttle valve for outstanding drivability and environment-friendly performance
In order to achieve both good drivability and environment-friendly performance, the BSR37 carburetor of the current "FZS1000 FAZER" has been replaced with a fuel injection (FI) system with the same structure as the YZF-R1. In addition to main throttle valve actuation, sub-throttle valve actuation is performed by motor drive that reflects information about rpm and degree of throttle opening via the ECU. This control system optimizes the intake air speed and realizes best volumetric efficiency in all rpm ranges and helps achieve excellent drivability in the low- and mid-speed ranges.
The injector features a long plate-type nozzle and is a four-hole two-way injection type with a high dynamic range. The fuel injection system adopts lightweight, return-less piping for a more compact design.

3) Superb rear wheel drive force that surpasses the YZF-R1 in the practical-use range
In the development of the "FZ1" and "FZ1 Fazer," in order to "achieve both emotional performance feeling and ease of use," focus was placed on rear wheel drive force as one element forming the foundation of riding performance: torque characteristics in each rpm range, optimal gear ratio settings, and the rear tire diameter were designed for optimum balance. These factors combine to realize a rear wheel drive force that is 7% greater than the YZF-R1 on ordinary roads and expressways in the practical-use range to achieve a feeling of strong acceleration.

4) Chamber-less exhaust pipe design and short-type silencer
To achieve both superb exhaust efficiency and an impressive, condensed silhouette, a chamber-less exhaust pipe and a hexagonal-design short-type silencer have been adopted. This has helped to efficiently bring out the characteristics of the new engine while also providing a unique exterior appearance.
EXUP is a system to improve intake/exhaust efficiency by preventing the "blow-back" phenomenon, and the version adopted on this model is a further development of the compact type EXUP on the present YZF-R1. It features a valve at the point where the four exhaust pipes merge into one. What's more, a heater-equipped O2 sensor inside the exhaust pipe and a 3-way catalyzer are adopted to achieve environment-friendly performance that clears the next level of European regulations (EU-3).


1) Newly designed all aluminum frame and CF aluminum die cast rear arm
In order to achieve a feeling of real emotion, a newly designed all aluminum frame made by metal mold casting has been adopted. The best rigidity balance in each of the vertical and horizontal directions and with regard to torsional force is realized, which contributes to achieving a high level of sporty handling. As with the YZF-R1, the design utilizes the engine as a stressed member of the frame. Rigid mounts are used at six positions, four at the backside of the engine and two on the back side of the cylinder head, on the left and right.
To achieve both excellent rigidity balance and an attractive external look of quality, a die-cast rear arm made by the Yamaha-exclusive CF aluminum die casting method has been adopted. A 629mm long-type arm has been adopted to minimize interference of chain tension on the drive force, which also realizes excellent cornering characteristics.

2) Front fork with separate left / right damping force generation
The front suspension adopts an upside-down fork with 43mm tubes, which is the same size as the YZF-R1 and achieves by both good cushioning and quick handling characteristics. For the "FZ1" and "FZ1 Fazer" a unique system is adopted that enables separate left/right damping force generation. In this system, compression stroke damping force is generated on the left portion of the fork and rebound damping force is generated on the right. This system has already been proved effective in the top class of road racing, MotoGP, with the 2003 YZR-M1. With this system, the direction of oil flow for damping force generation is always the same, which makes for simplified setting.

3) New dimensions with 51% front wheel weight distribution
In order to enable the rider to get a good hold on the machine with the lower body and make step work more fluid for enjoyable machine handling, the mounting position of the engine has been shifted 35 mm toward the front end compared to the "FZS1000 FAZER," distributing 51% of the weight on the front wheel. The wheelbase length is 1,460 mm. The caster angle has been changed to 25 degrees (presently 26), fork offset is set at 25 mm (presently 35mm on the FAZER), with all dimensions optimized to bring about light, athletic handling.

4) Other chassis related features

Other features adopted include: (1) MOS x 64 caliper φ320mm front disk brake; (2) lightweight front and rear wheels with the same specifications as the YZF-R1; and (3) a new meter with a fade-in function so the backlight comes in slowly when the rider turns the key on.
