  • Monster 1200R.

    The most powerful Monster yet, we rode this one in our November 2015 issue. According to our international bike guru Roland, the 1200R is the fastest, most aggressive and entertaining Monster yet.
  • NEW 2016 KAWASAKI ZX-10R.

    With World Superbike regulations becoming ever stricter with regard to modifications, manufacturers have to make sure their production models already have the proper pieces in place. And after winning two World Superbike championships in the past three years, Kawasaki shows that it’s serious about staying at the top of the superbike heap with its all-new 2016 ZX-10R. All of the extensive updates to Team Green’s new literbike were gleaned from lessons learned in WSBK competition and intended to make sure the factory team has a solid base to start from for the coming season. Engine Other than the previous engine’s bore and stroke, there’s little carried over between the old and new ZX-10R. The new crankshaft is lighter for quicker response and improved handling, with a correspondingly lighter balance shaft and rod journals that have a new coating for reduced friction at higher rpm. New 5-gram-lighter pistons, cams with more overlap, and a new airbox (25 percent more volume and air filter with 60 percent more surface area for better fl ow) work with an all-new cylinder head featuring reworked and polished intake and exhaust ports (previously only the intake ports were polished) plus revised combustion chambers. The titanium exhaust valves increase in size 1mm to 25.5mm, and cylinder-wall thickness was increased slightly for a more rigid engine block. The titanium alloy headers use a new heat-resistant alloy that allows thinner wall thickness for reduced weight, and the titanium exhaust canister has 50 percent more volume for better fl ow without increased sound levels. The intake portion of the frame’s steering head was modified to quell intake honk, allowing some freedom in the exhaust for more power without exceeding strict noise restrictions. The transmission remains a racing-style cassette design for quick and easy internal gearing changes. Gear ratios are closer for track use, with shorter ratios in all but first gear. The slipper clutch is 130 grams lighter, and some of the gears have dry-film lubricant coating to reduce friction. A contactless- sensor-equipped quickshifter similar to the H2R is standard, with the optional Kawasaki race ECU offering clutchless downshifts as well. Electronics The new ZX-10R utilizes a Bosch five-axis IMU with software developed in-house at Kawasaki that allows the unit to calculate yaw rate from other sensors, resulting in six-axis operation. This allows the IMU to sense changes in pavement elevation, camber, and the motorcycle’s position relative to them, as well as discern different tire profiles so that the bike is not restricted to just the OEM tires. The Sport-Kawasaki TRaction Control (S-KTRC) system now has five modes of operation instead of three as with the previous ZX-10R. Modes 1 and 2 are designed for racing, while mode 3 is for a “dry circuit with highgrip tires,” mode 4 is for “dry canyon roads or commuting,” and mode 5 is intended for wet pavement use. The Keihin 47mm throttle bodies utilize an electronic ride-by-wire throttle system to control power in addition to ignition retardation. With the Bosch IMU, Kawasaki was able to produce its own version of the cornering ABS that has seen usage on KTM and BMW motorcycles. Kawasaki’s system is called Cornering Management Function and changes braking pressure according to the bike’s lean and pitch angles to prevent it from standing up under braking in a corner. Another new addition is the Kawasaki Launch Control Mode (KLCM), with three modes available. And Kawasaki Engine Braking Control-first seen on the supercharged H2R-manages engine back-torque. Lastly, there are three selectable power modes for the new ZX-10R: Full, Middle (providing approximately 80 percent power), or Low (allowing 60 percent power). Chassis The new Ninja’s frame has also been redone, with the steering head moved rearward 7.5mm closer to the rider, while the swingarm has been lengthened 15.8mm (in addition to extra bracing for more torsional rigidity), resulting in more front weight bias. Wheelbase is now listed as 56.7 inches, almost a half inch longer than its predecessor. An all-new Showa Balance Free Fork featuring an external damping valve chamber utilizes a design similar to the ?hlins TTX/FGR concept, with the rebound and compression damping valves completely separated so that the oil only flows in one direction through the valves; in conjunction with nitrogen pressurization in the damping chamber, this keeps the pressure on both sides of the valves as consistent as possible, drastically reducing cavitation that results in inconsistent damping. The rear Showa Balance Free Rear Cushion (BFRC) shock uses the same concept in its damping valves, and the shock linkage has been revised to allow a broader range of adjustment. Brakes have also been fully upgraded, with Brembo M50 monoblock aluminum calipers with 30mm pistons biting on huge 330mm discs for awesome stopping power. A Brembo radial-action master cylinder equipped with steel-braided brake lines ensures positive and responsive feel at the lever as well as better consistency. Wheels are one of the few components that haven’t been changed, though they are now shod with Bridgestone RS10 street/track rubber in 120/70-17 front and 190/55-17 rear sizes. Bodywork has undergone some restyling, with the windscreen improved for better aerodynamics. Overall weight is claimed at 450 pounds wet with all fluids and a full tank of fuel for the non-ABS model, 454 pounds wet for the ABS model. List prices are $14,999 for the standard ZX-10R, $15,299 for the Special Edition paint, $15,999 for the ZX-10R ABS model, and $16,299 for the ZX-10R ABS with Special Edition paint scheme. How will all of these changes affect Kawasaki’s performance in World Superbike and on the showroom floor? We can’t wait to find out.
  • REAL-LIFE MONSTER.

    The difference in the Ducati engineer’s tone is almost so dramatic that I can’t believe he’s talking about what outwardly appears to be a very similar bike. Last year, I was on hand for the introduction of the Ducati Monster 1200 S, and Ducati’s technical team was using words like “usability,” while going on to say things like, “We want the Monster 1200 to offer greater comfort and accessibility to both rider and passenger.” Today, at the Ascari Race Resort in Malaga, Spain, the same team has done a near complete 180 and is talking about things like added ground clearance for better lean angle and quicker lap times. Such is the goal with Ducati’s new Monster 1200 R… The R utilizes a Testastretta 11° engine similar to that in the 1200 S, only this one uses a thinner head gasket to bump compression ratio up to 13:1 and is paired to larger elliptical throttle bodies with an equivalent diameter of 56mm (versus 53mm on the 1200), plus larger, 58mm-diameter exhaust pipes. Together, these changes bump power output to a claimed 160 hp at 9,250 rpm and torque from 91.8 foot-pounds at 7,250 rpm to 97 foot-pounds at 7,750 rpm. To help the R meet strict Euro 4 emissions standards, Ducati is also using a new material on the piston to reduce leak and has added material to the clutch cover to reduce mechanical noise from the oil pump. Despite the weighty updates, Ducati has actually managed to reduce the claimed curb weight of the R by almost 5 pounds, to 456 pounds, a drop aided by new forged aluminum wheels. For better handling, the 1200 R’s fully adjustable ?hlins suspension has been lengthened (this increases cornering clearance and raises the bike’s center of gravity for lighter handling) as well as re-damped. The effect on geometry is minimal, with the R having just a 2mm-shorter wheelbase (1,509mm versus 1,511mm on the S) and 4.2mm less trail (89mm versus 93.2 on the S). Electronics are the same as they are on the Monster 1200, which is to say the bike has the same three riding modes (Sport, Touring, and Urban) that can be customized via three varying power modes, three-level ABS, and eight-level DTC. All of these settings continue to be adjusted via a switch on the left side of the handlebar and through the Monster’s dash, which now has a gear position indicator. In all situations except for when the sun is directly behind you, all of the bike’s electronic settings are clearly visible. But damn that sun… Additional updates for the R include an ?hlins steering damper, larger 200/55-17 Pirelli Supercorsa SP rear tire (instead of Pirelli Diablo Rosso II rubber), and separate rider/passenger footpeg brackets, the former holding pegs that are machined for better grip and live on an extremely short list of Ducati footpegs that we like (and actually work to keep your feet on the pegs during aggressive riding). Throw a leg over the bike and you’ll notice right away the effects of the new seat and taller suspension, which together bring the seat height from 31.9 inches max on the Monster 1200 S to a nonadjustable 32.7 inches on the 1200 R. While that number doesn’t seem skyscraper high, it’s defi- nitely worth keeping in mind if your parents didn’t grace you with long legs; at 6-foot-3 I could fl at-foot no problem, but my legs were definitely straighter than they would be on similar bikes. The R’s handling makes the bike feel surprisingly at home at the track (and will likely do the same on a twisting canyon road). Even with the larger 200-section rear tire out back, the bike steers into a corner lighter than the standard 1200 and through a transition quicker thanks to the higher center of gravity (and forged wheels, we’re sure). On top of that, when it’s on its side, the re-damped R feels more planted and composed than ever before. I am generally not a huge fan of naked bikes on the track, as the wider handlebar paired to streetsoft suspension typically causes those bikes to move around quite a bit through all parts of the corner, yet with the R there’s relatively none of that unwanted movement, even as the pace picks up. At the other end of a straight, the 1200 R continues to stand out with great braking power from the M50 monoblock calipers and a good feel through the chassis as you bank into the corner; again, not something you get from most street-biased naked bikes. Compare dyno charts between the Monster 1200 R and the 1200 S and you’ll notice that the bikes make about the same power most everywhere below 7,000 rpm. So, similar to the S, the R makes good power off the bottom and can be run in a gear higher than you’d expect in tighter sections of road, the obvious benefit being less shifting over the course of a ride or session at the track. Past 7,000 rpm, the R’s engine starts to pull a bit harder and doesn’t feel like it goes fl at as you close in on the rev limiter. For some, that added liveliness will be the punch to the adrenal glands that the S simply couldn’t give. But there’s more to the engine than a little extra performance up top, as when Ducati engineers mounted the larger throttle bodies they also went through and fine-tuned the parameters for the new Synerject-Continental fuel-injection system. The result is near seamless fueling almost right off the bottom. Whether you’re riding stoplight to stoplight or going to crack the throttle open in the middle of a corner, this has obvious advantages in that it makes the bike less work to ride or stay on top of. And overall, that’s what the Monster 1200 R feels like to me: an easier bike to ride. Sure, it’s a bit faster, but more importantly it’s lighter on its toes and more composed when ridden aggressively. Add in electronic rider aids like traction control and ABS that can be easily tailored to provide as much support as you need (and without being overly intrusive) and you have a bike that’s surprisingly well suited for track riding. Now, there’s something I probably wouldn’t have said about the standard Monster 1200.
