Brilliant handling, impressive power and a stunning design, the much improved FZ6 has everything that most riders demand in a sporting motorcycle and more. Tourer, commuter, or sports bike, the new FZ6 does it all. An exciting R6S based engine provides plenty of power while the all new front brakes slow it down in a hurry. A revised seat and new fairing provide all day riding comfort. Whether carving up a back road or winding your way through city traffic, the FZ6 provides the kind of fun and excitement that motorcycling is famous for … all at a very affordable price.

FEATURES:

- R6"S" based, ultra-compact, 600cc, liquid-cooled, DOHC, 16-valve, slant block inline four powerplant. Virtually all the internal engine components are R6"S" spec including crankshaft, con rods, valve sizes, bore & stroke etc.

- Specially designed, one-piece cylinder and upper crankcase assembly provides superior engine rigidity and reduces weight.

- Ceramic plated sleeveless cylinder bores provide greater heat dissipation for consistent power delivery and reduced frictional power loss. Sleeveless design also reduces weight.

- Lightweight forged pistons feature carburized connecting rods for superb strength and reduced reciprocating mass. The result is incredible engine response.

- Hollow side-driven camshafts with computer perfected valve timing help create a very narrow engine. The key difference between the R6"S" and FZ6 engines is the camshafts in the FZ6 have revised cam profiles and slightly different intake tracts for more low to mid range power.

- One-piece cylinder and upper crankcase assembly provides superior rigidity and reduce weight.

- Lightweight forged pistons run in ceramic composite plated cylinders.

- Compact slant-block engine uses stacked gearbox shafts to create a shorter engine (front to back) which allows for optimum engine placement in the frame for a balanced weight distribution and great handling.

- "Liner less" cylinder has special ceramic composite plating applied directly to the aluminum cylinder block for greater heat dissipation, reduced frictional losses, reduced oil consumption and lighter weight.

- "Tri-Axis" 6-speed transmission has been optimized to accommodate the engine character of the FZ6. The secondary reduction ratio is 46/16 (Vs. a reduction ratio of 48/16 for the R6S). Gear widths, splines and engagement dogs are optimized for smooth shifting under power.

- "Tri-Axis" or stacked transmission design creates a more compact engine front to back that allows for optimum engine placement in the frame for optimized balanced weight distribution and incredible handling.

- "Group-Type" Mikuni 36mm throttle body fuel injection provides outstanding throttle response and excellent fuel economy. This system uses fewer sensors (5) than the R6"S" (7) while also being lighter and more compact.

- Group fuel injection divides the four cylinders into two groups (1 & 4 and 2 & 3) with two injections of fuel for every 720 degrees of crank rotation (the R6"S" system utilizes a sequential injection for each cylinder).

- Compact "high dynamic range" injectors use 4-hole / 2-direction spray type injectors. A high powered, compact 32 bit CPU controls the injection process. For 2007 the FI settings and mapping were revised for improved performance in the most often used speed ranges.

- Progressive type throttle pulley and direct coupler type TPS (throttle position sensor) provides easy throttle control without the annoyance of FI surging.

- 6.3 litre airbox is "optimized" to take full advantage of the downdraft intake system.

- Air Induction System (AIS) reduces harmful hydrocarbon and carbon monoxide (HC & CO) emissions.

- Revised 4 into 2 into 1 into 2 stainless steel exhaust system features a stylish under seat muffler that is a one piece unit with dual outlets. A special resin cover protects the muffler and keeps hot components away from the rider and passenger.

- A special connector pipe joins the header pipes between cylinders #2 and #3 pipes to provide outstanding low to mid range torque.

- The revised exhaust system now utilizes a total of 3 honeycomb catalytic converters to reduce harmful emissions such as CO, HC, CO2 and NOx into less harmful by products. The result is very clean running engine that easily surpasses the new EU3 European emission standards.

- New heater type oxygen sensor has been installed in the exhaust system to provide continual info back to the ECU which in turn provides the optimum fuel/air mixture for impressive performance with reduced emissions.

- Revised, larger high capacity radiator with ring-type cooling fan insures maximum cooling efficiency.

- Liquid cooled oil cooler maintains consistent oil temperatures for extended engine and lubricant life.

- R6 based clutch assembly is utilized but the clutch boss, spring rate and friction plates are specially designed for the FZ6.

- Maintenance-free transistor controlled digital ignition ensures fast starts and optimum engine performance.

- High tech, C.F. (controlled fill) die cast twin spar main frame is used. There are no welding points on this frame, since it bolts together. A rigid type engine mounting system is used to increase overall chassis rigidity for great handling and also to reduce the weight of the actual frame.

- Front / rear weight distribution is 51% front and 49% rear for light, responsive handling.

- Detachable steel rear sub frame provides easy access to the rear shock and reduces costs in the event of a "loop-out".

- New, extra long extruded box section aluminum swingarm has been re-designed for improved rigidity and improved appearance. The chain adjuster area is revised as well. The long design provides maximum rear wheel traction and a light handling feel that the FZ6 is famous for.

- Revised conventional 43mm cartridge style forks provide great handling and excellent ride comfort. Plastic protectors help prevent tube damage due to stone chips. Wheel travel is 130mm (5.1"). The appearance of the lower fork leg sliders has been improved with the addition of an "Alumite" finish. The caliper mounting area has also been revised to accommodate the new 4-piston monoblock calipers.

- "Link less" rear suspension means the rear shock mounts directly to the frame and swingarm without the use of linkages. The rear suspension system has been designed to provide a rising rate feeling without the additional weight of linkage arms and pivot points. The shock features 7-way spring pre-load adjustability. Wheel travel is 130mm (5.1")

- Revised dual 298mm floating front disc brakes are squeezed by new 4-piston, ultra rigid R6S inspired monoblock calipers. Braking performance is impressive and lever feel is excellent. "Trifurcate type" front brake hose reduces weight (Trifurcate type brake hose means there is one brake hose from the master cylinder and it splits at the front fender area and crosses over to the second caliper).

- 245mm rear disc brake with Nissin single piston caliper provides outstanding stopping power.

- New, more sporty FZ1 inspired ½ cowl offers great wind and weather protection. This new fairing features a revised mounting position that is 33mm lower and 18mm more forward. An inner panel around the instrument area provides a clean, quality image for the "cockpit". The fairing also features a new, more stylish 'conventional" windshield design that it easier to clean than the old version. This new windshield also reduces turbulence and noise in the cockpit

- Stylish 19.4 liter (4.3 Imp. gal.) fuel tank (3.6 liters is the reserve portion) features an in-tank electronic fuel pump.

- Lightweight R6 style, 5-spoke mag wheels fitted with Z rated radial tires reduce unsprung weight for incredible handling performance.

- New one-piece seat design offers excellent comfort. The seat foam has been revised to be slightly softer for improved rider and passenger comfort. The seat cover material has also been changed from a dimpled material to a smooth design.

- New, more aerodynamic front fender wraps around the fork leg to provide a more sporty appearance.

- All new, FZ1 based multi-function instrument assembly. Features include an analog tach, digital speedo, dual tripmeters, fuel reserve tripmeter, clock, fuel gauge and water temperature as well as a selection of warning lights. The back lighting can be adjusted to suit rider preferences.

- Conventional handlebar design provides a comfortable riding position and also allows easy handlebar replacement. The handlebar holder has been changed from a 2 piece design to a more stylish single component embossed with the Yamaha tuning fork.

- New stylish aluminum passenger footrest brackets improve appearance. The passenger footrests have also been lower 25mm and moved forward 10mm for improved passenger comfort.

- R1 inspired dual "cat eye" halogen headlights cast a bright beam of light. (Note: Only one headlight - RHS- lights on low beam. Both lights light on high beam)

- All new helmet holder with lock

- Convenient passenger grab rails

- Inner rear fender reduces splash and provides that sporty appearance.

- 5-position adjustable front brake lever

- Rider footrest brackets are rubber mounted to reduce vibration

- Super convenient center stand makes chain adjustments and tire changes a snap

- Low maintenance sealed 12 amp hour battery

Review

Deep inside the Yamaha lineup there’s a model that doesn’t garner very much fanfare, and yet is something of a welcome salute to the old days—the FZ6. The little brother of the FZ1, the 2007 FZ6 hasn’t changed all that much from the bike we tested in April of last year, but the new version gets updated fuel-injection programming, a revised gauge cluster with an easy-to-read analog tachometer (which replaces the old digital unit that was hard to read), and a redesigned fairing and windscreen. The biggest change on the new model is a revised swingarm and a switch to monoblock four-piston calipers (as seen on the R6S) hugging the front discs in place of the old two-piston pin-slide calipers. We never had a problem with the old binders; in fact we gave them the nod in comparison tests with the FZ6’s competitors, but we’ll gladly take the upgrade.

Not only is the FZ6 aimed at the new rider, but budget-conscious riders looking for a thrill can get a kick out of the bike as well. At the heart of the FZ6 is the R6S engine, which has been retuned for better midrange rideability. Keep in mind that this is the same basic engine that Yamaha used to win AMA Supersport victories and the 2003 championship, so it’s definitely no slouch. On the dyno the retune translates into 84 rear-wheel horsepower at 12,100 rpm and 41 lb-ft of torque at 10,100 rpm, real punch for a bike in this weight range.

Thumb the starter button on the FZ6 and it springs to life, but don’t be too quick to jump on and ride—the fast idle needs some time to bring the bike up to operating temperature. Click it into first gear and an abrupt thud is there to greet you every time. Once moving, the six-speed transmission is slick, with positive engagement from the slightest flick of the toe. Our test bike had a rather stiff throttle spring that made long-distance trips at constant throttle an exercise for the wrist, but for short trips around town—where engine speeds vary—it wasn’t noticeable. Sort your way through the gearbox and the top-end rush of the 600cc mill is so intoxicating that perhaps the throttle was designed that way to protect those with heavy right hands from landing in the slammer!

The new fuel-injection programming is also spot-on, especially during midcorner application, as the engine was always smooth and responsive. Get that left ankle in shape, though, because the peaky nature of the engine means that constant shifting is required to keep the FZ6 in the powerband. And while the top-end power is nice, the price you pay for that fun is some buzziness in the handlebar that can numb the hands on a long ride. The shape of the gas tank doesn’t help take weight off the wrists as its narrow and rounded contours make it hard for the rider to support his or her weight with their legs. Fortunately the riding position is rather relaxed, and not much weight is on the wrists anyway. You are sitting slightly forward, but nowhere near sportbike standards. For truly comfortable touring a higher bar position would do the trick.

In the tight stuff the little Yammie performed admirably, my only gripe being that it was difficult to move around in the saddle as the new seat material latched on to my riding pants. Body positioning through turns doesn’t suffer as long as you prepare yourself ahead of time. The same non-adjustable 43mm fork from the previous generation FZ6 sits out front, this time finished in black to complement the aluminum frame and swingarm, while the single preload-adjustable shock resides in the rear. The fork could use a little more damping both in rebound and compression, but turn-in wasn’t overly sluggish and the bike held its line. Bikes in this price-point often tend to “pogo” through turns as their suspensions can’t keep up, but not so on the FZ6. The rear shock was expectedly soft, and although the preload is the only thing to play with, it didn’t show any signs of wanting to bounce or wallow.



Speaking of price-point, at first glance one would think that the 600cc engine is the star of this show and would drive the price up, but when you look at the complete package and how well it all works together one starts to wonder how Yamaha could only want $6,849 for it. For that price new and experienced riders get a motorcycle that scores high on the smiles-per-mile scale without breaking the bank.

As mentioned earlier, the biggest change to the ’07 model is the four-piston calipers that clamp on dual 298mm floating discs. Braking is strong and linear, although the rubber lines tend to flex and make braking feel spongy after repeated hard usage (like during our photo shoot). This bike isn’t one that would see hard stopping on a repeated basis anyway, so unless you like braking to the point where the discs get red hot, the standard rubber lines are fine for the job.

On the open road the peppy engine is ready at a moment’s notice and the seat is neither too soft nor too firm. Yamaha claims the passenger seat and footpegs are supposed to be more comfortable for a pillion, and the passenger grabrails are some of the biggest in its class. So grab a copilot and go for a ride—just make sure you are quick with that shifter—you’ll need to be if you want to keep the engine happy, especially two-up. During our (mainly solo) testing, the metal gas tank was an ideal location for a magnetic tankbag, and the large, flat flypaperlike rear section proved to be a prime spot to put soft luggage. You’ll need it, too, as the underseat exhaust takes away any storage space. So if two-up touring is your game, then you had better travel light, but if you prefer traveling solo you’ll find yourself comfortable with just enough room to pack a little more.

During our mixed testing of local commuting, jaunts through the canyons and the occasional weekend trip, the little Yamaha averaged an amazing 47 mpg from its 5.1-gallon gas tank. Great fuel range is something we’ve liked about the FZ6 in the past and fortunately the retuned fuel injection keeps that tradition alive. The restyled fairing and windscreen no doubt punch a cleaner hole in the air, thus also helping in the mileage department. Our previous gripe was that the windscreen was too far forward and didn’t protect the rider much. The new windscreen is closer to the rider but the wind still hit this 5-foot 8-inch rider’s helmet and created some buffeting, sometimes coming underneath the chinbar on a windy day. In a tuck, however, the windscreen does a great job of deflecting the wind away from the hands and the head. Shorter riders should appreciate the windscreen even more.

We’ve logged plenty of miles on current and former models to really notice the little things about the FZ6 that stand out. Yamaha definitely gets points for equipping the 6 with a centerstand—making parking in tight spaces and performing basic maintenance a breeze. Yamaha also gets credit for supplying a fully stocked toolkit that seems fit to perform anything short of a complete overhaul. Rubber-mounted footpegs are a subtle touch on the FZ6 that are normally overlooked on bikes costing twice as much. Despite not damping all the buzz from the engine, they do isolate most of it before it reaches the rider. Again, little things….

What we have with the FZ6 is a legitimate middleweight standard with the versatility to keep experienced tourers entertained and the simplicity to keep the newer rider from getting in over his or her head. Despite our minor gripes, the engine is fit for the job and the adequate suspension is actually a good learning tool for being smooth. Throw in the quality brakes and all the provisions for luggage and you get a bike that’s a welcome tribute to the versatile way things used to be. Sometimes the old ways are the best ways. The fact that Yamaha doesn’t even want seven large for the FZ6 is just icing on the cake.
