Honda VFR 1000. - 990 CC MotoGP heritage

In 2009 Honda launch a high-end SUPERBIKE VFR titled 1000 which will be makers lose variants and VFR 800 CBR 1000 XX Superblack bird. VFR 1000 variant that will be set back into a sport Tourer variants like super black bird will be implanted in the kitchen Provide multi-cylinder 1000 cc V5 which is an evolution of rumors kitchen HRC V5 runway at the last MotoGP event (Honda RC 211V could also be developed by Valentino Rossi).

Because Referring to the RC MOTORCYCLES 211V, engine architecture was not much different: 3 cylinder 2 in front and behind the cylinder, Honda seems to be pouring all his research results about the RC 211V for five years on this VFR, the motor would be motors berprestis high because the first street bike engined V5. Even Honda to appoint as leader Yoshiteru Kinoshita project was VFR 1000, FYI he has experience working with the technicians and the team researc HRC CBR 1000 RR 2008.

FMF Racing Apex Exhaust on Kawasaki ZX-10R - Tested

Ask first ten riders aftermarket purchases they made for their motorcycles and the possibility of nine of them will give the same answer: a drainage system. It's hard to resist whining howl of the engine full song, and let the engine breath easier not only release more than a beautiful exhaust note, but it also can liberate a certain power in the process. The problem was always that the change in air / fuel ratio caused by a new exhaust, the reconfiguration of the fuel injection (or re-jetting the carburetor to those who have an old bike) to achieve the right mix is usually required.

FMF does not think that should happen. Its line of Apex slip-on exhaust is completely designed and manufactured in Southern California headquarters to operate without recalibrating the motorcycle stock fuel system. Although relatively new on the market side, FMF has been heavily involved in off-road competition in both two-and four-stroke engines for over 30 years. Companies that do not dip your toes in the street scene, although they hit the ground running. In the AMA, the Corona Honda Superbike team are given U.S. FMF exhaust, FMF and other road is wide enough supply.

Want to know the performance benefits of Apex without recalibration fuel injection, we decided to test us Apex Kawasaki ZX-10R. The exhaust is available in two versions - a carbon fiber tube with the tip of titanium, or titanium canister with carbon tip. A titanium mid-pipe comes with each kit. We accept carbon tubes for the Kawi. Installation is quite simple as the directions and all necessary hardware is included. Also included is a conical insert keep quiet exhaust note and good neighbors.

FMF Apex Exhaust tested Chart

The first thing we noticed was an increase mid-range power. Of course, this all according to our butt dyno. So the trip to the official Dynojet dyno we were in the order. Shares, ZX-10R us out 75.6 horsepower and 161.7 ft-lbs of torque. With Apex unlimited-slip on these numbers jumped 76.5 horsepower and 164.0 ft-lbs. In contrast, the cones in the most quiet (most restrictive) settings, the number fell slightly to 161.2 and 74.8, respectively. Yes, less horsepower and torque than the standard configuration.

While the numbers are significant, what is more important is the dyno curve, as the application of power to say more subtle than before. Shares, the ZX-10R will be dead spots when a gas-usually between 4500 and 5000rpm-effect mother nature trying to make happy. Flat spot now gone, replaced with a smooth and linear power delivery of the entire rev range. What's more, drops Apex fairly heavy piece by cutting the stock cans; the Kawasaki dropped nine pounds, to be exact.

Although they may be a new game, FMF dirt obviously has brought expertise from side to side of the road with a series of Apex muffler. In all of our exercise power output has been smoothed away, so for linear delivery of power where you use it most. The Apex you see here retails for $ 549.99, though pricing is different for underseat and dual-exhaust setup.

2010 - Yamaha YZ250F Off Road Sport Motorcycle

All New for 2010 Key Features:

• The all-new, Bilateral Beam frame is specific to the 250 and is more compact than the previous generation chassis. This places the rider closer to the front wheel, which delivers superb rigidity balance for unmatched lightweight handling and cornering. This nimbleness lets the rider get on the gas sooner out of corners and cross the finish line with less fatigue – even on long motos.
• The optimized engine delivers a new level of power in low-to-midrange,
  with a great torquey feel, exactly where riders want it. That is due to the new straight intake boot that enhances breathing, new carburetor that provides excellent throttle response and fuel atomization, and redesigned valve train components that reduce inertial mass and boost low end torque. Exhaust is also enhanced with a new D-shaped exhaust port and newly designed exhaust system. Ongoing refinement to the suspension and engine produces an amazingly balanced, light-handling machine with performance that’s accessible to all levels of riders.
• All new styling emphasizes the bike’s light weight and nimble handling character. The sharp, horizontal lines set the bike apart, with a clean, aggressive look.
• KYB® suspension has been recalibrated front and rear and is tuned to work with the new Bilateral Beam frame for unmatched handling. The clutch lever has a lighter pull feel even though the clutch has stronger engagement. The new clutch also has a wider engagement range that will give riders an advantage off the line. . . shift after shift, moto after moto.
• There’s no disputing the YZ250F’s unmatched four-stroke prowess – it was the 1st four-stroke 250 motocross bike on the market, the 1st to win an international race, the 1st to win an AMA® Supercross ® and the 1st to take an AMA® U.S. Supercross Championship® title, as well as the first to win an AMA® National race.
  

Engine:

• The valve spring retainers are now lightweight aluminum instead of steel, and valve spring pressure is lighter for reduced valve opening force. This contributes to superior low-to-mid range torque characteristics due to less power-robbing friction. There’s also a new, higher lift cam profile, while valve stem ends are chromium-nitride coated for exceptional reliability and reduced maintenance.
• The exhaust port shape has a “D” shape instead of round. This increases velocity through the port for excellent throttle response, while enhancing the power feeling of the engine.
• The newly designed radiator is lower and further back and the oil tank is more compact and repositioned to achieve greater mass centralization.
• The carburetor bore has a new venturi shape, plus there’s recalibrated jetting and a new accelerator pump. This translates to impressive response when the rider snaps open the throttle, and contributes to superb torquey low-to-midrange power characteristics.
• The intake boot offers a straight, smooth tract for excellent engine breathing and more power. The airbox is reshaped to tuck neatly into the Bilateral Beam frame.
• The exhaust pipe has been carefully tuned to optimize engine power, with a muffler that’s 50mm longer and with a narrower core – a design that lets the YZ250F comfortably meet the latest noise standards without sacrificing power.
• Engineers were able to increase the clutch spring load for stronger engagement, yet, thanks to a recalibrated clutch actuation arm cam ratio, lever pull is actually lighter than before.
• Third and fourth gear ratios are slightly taller, and third, fourth, and fifth gears are stronger than ever with new drive dog shapes for positive engagement. That gives riders a strong gearbox that’s been carefully matched to engine power characteristics.
  

Chassis/Suspension:

• The Bilateral Beam frame is crafted from a carefully chosen combination of forged and extruded aluminum pieces – 20 in all – all welded together to provide unmatched rigidity balance.
• The KYB® speed-sensitive front fork delivers exceptional damping feel, responsiveness, and bump absorption characteristics. Damping settings are revised, the piston rods have a new surface treatment, and the oil seal is a new design.
• The 4-way-adjustable KYB® rear shock has been redesigned to make the most of the Bilateral Beam frame design. It’s lower in the frame for excellent mass centralization, and has new damping characteristics.
• The new tank, seat, and rear fender are flat and the relationship between handlebars, pegs, and seat result in a natural, more forward riding position that facilitates rider movement. The fuel tank has been moved toward the center of the bike for mass centralization. The ProTaper® bars are four-way adjustable, and handlebar mounts and footpegs are 5mm higher to optimize rider position on the new chassis.
  

Additional Features:

• The CDI unit has revised ignition mapping to match new engine intake and exhaust specs.

2010 - Yamaha YZ450F Off Road Sport Motorcycle

All New for 2010

• YZ450F’s new rearward-slanted cylinder is a revolutionary advancement that achieves unmatched mass centralization, concentrating inertial mass toward the center of the machine. This bold new design also swaps traditional intake and exhaust positions, putting the lightweight airbox and throttle body out front. This contributes to mass centralization for nimble handling while also achieving a straight intake tract for superb combustion efficiency that delivers more power.
• The cylinder is offset so the connecting rod is vertical at the moment of greatest combustion force, minimizing piston friction against the cylinder wall that could rob power. That means quicker response.
• The new 4-titanium valve cylinder head is matched to a fuel injection system developed specifically for the YZ450F. Instantly adapts to changing air/fuel mixtures depending on altitude and temperature, for an engine that delivers no matter what conditions.
• The all-new aluminum Bilateral Beam frame provides a superb rigidity balance that complements the engine for unmatched lightweight handling and cornering. The result? The best cornering, most nimble 450F for all track conditions.
• Revamped looks deliver new-generation styling, including front and rear fenders, intake cover, front fork protector, and number plate, along with the fuel tank and seat.
• Accessory GYTR® Power Tuner lets bike tuners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions.
