  • CRF 1000L Africa Twin.

    Honda unveiled the celebrated CRF 1000L Africa Twin in Europe for the first time at EICMA. This adventure-tourer motorcycle is powered by a 998-cc parallel twin engine that draws heavily on Honda’s CRF 250 and 450 competition machines and uses the same four-valve Unicam head design. While the standard Africa Twin is available with a six-speed manual gearbox, there are two more versions to be had. The first features ABS and Honda Selectable Torque Control (HSTC), which controls the amount of torque going to the wheel and, in doing so, prevents or allows wheelspin. The last variant of the Africa Twin features Honda’s Dual Clutch Transmission (DCT) that was first seen on the VFR 1200F. Unlike on the sports tourer, however, on the Africa Twin, the DCT has also been programmed to function off-road. Unfortunately, it seems unlikely at the moment that the CRF 1000L Africa Twin will head to India anytime soon, but there’s no harm in hoping, is there?
  • Audi’s electrified future.

    The introduction of mild hybrids to Audi’s model range is set to edge efficiency ever closer to the kind of economy figures enjoyed by TDI owners. But it doesn’t mean the death of the diesel engine, as the introduction of cutting edge technology can be paired to both TDI diesel and TFSI petrol engines. Audi says that within ten years, its entire model range will feature the technology. The key elements of the new system are an 11 Ah capacity lithium-ion battery pack and belt starter generator, with the latter replacing the current starter motor. Coasting becomes possible from around 9mph upwards, so that if the driver takes their foot off the accelerator, the car will coast along for a short time with the engine off, saving fuel. It’s possible to recuperate up to 5kW (7bhp), with the generator returning that power, reducing fuel usage and boosting economy as a result. And while this system can be integrated into current 12-volt systems, Audi is on the verge of announcing that it will put a new 48-volt system into production, with a capacity of harnessing 12kW (16bhp), that will allow coasting for up to 30 seconds, delivering even better efficiency compared to the 12-volt system. The company first gave a glimpse at the technology in the Prologue Concept car last year at the Los Angeles motor show. Other benefits of the introduction of a 48-volt electrical system includes the ability to have much smaller cable cross sections, reducing the weight of the wiring harness, and because it has four times the power, there’s opportunities to add additional innovative technology for the suspension and drivetrain. Further into the future, Audi’s engineers plan to convert the auxiliary systems, like pumps, superchargers for the engine, transmission and air conditioning system to 48 volts. Today these are driven hydraulically or by the engine, but in the future they will be powered by electricity and lighter and more compact. Audi will soon announce an electromechanical active roll stabilisation system, which features an electric motor and a three-stage planetary gearbox that separates the two halves of the stabiliser from each other. For relaxed and comfortable driving, the two halves are decoupled, resulting in cossetting ride comfort. For the sportier driver, the tubes are interconnected and twist against each other, delivering a tauter, more dynamic ride, and less roll when cornering. The front and rear stabilisers can also be adjusted independently allowing even greater degrees of fine tuning. The system is also capable of harnessing energy, and the motor can act as a generator, converting it to electrical energy. But Audi’s engineers are already looking at a second, more advanced project using the 48-volt setup, though it is still in the very early prototype stage. Being developed under the working title of eROT, an electromechanical rotary damper replaces today’s hydraulic item. The system isn’t too far apart from the active roll stabilisation arrangement in terms of basic principles, but a strong lever arm absorbs all of the forces that occur on a bumpy road, and via a series of gears, the force is transmitted into an electric motor, which then converts it to electricity. Recuperation is, on average, around 150 watts on an average road, with a freshly resurfaced road generating as little as 3 watts, while a badly maintained country lane may generate as much as 613 watts. Over a cross section of different roads, CO2 emissions savings could be as much as 3g/ km or four to five mpg.
  • MIDSIZE ROLE PLAYER.

    The naked standard motorcycle category appears to have finally taken hold in the US, due in large part to the sales success of Yamaha’s bombshell FZ-09. After Suzuki’s challenge to the Yamaha triple (“Budget Blasters,” October/November 2015), now Kawasaki is jumping into the middleweight standard fray by bringing its Z800 ABS to the US market for 2016. Well, 49 states for now; California residents unfortunately won’t get the bike yet due to the added emissions requirements. Available since 2013 in other markets, the Z800 is powered by a liquidcooled, DOHC, 806cc inline-four that is basically a bored-out, upgraded version of the old Z750 engine. A 2.6mm-larger bore with 10-percent-lighter pistons getting cooled by larger oil jets, revised intake/exhaust ports, longer intake manifolds, and a staggered intake funnel setup along with 2mm-larger throttle bodies (now 34mm) boosts peak horsepower by a claimed 6 hp to a 111 hp peak in European tune (Kawasaki USA wasn’t listing power figures). Longer exhaust header pipes with equalizer tubes between cylinders and an exhaust valve in the under-engine chamber help midrange power. The European press has had plenty of good things to say about the Z800’s engine, and after a day spent riding in the streets of Palm Springs and up in the canyons of the San Jacinto mountain range, we’d heartily agree. There’s plenty of responsive low-end and midrange acceleration, aided in part by the change to a two-teeth-larger rear sprocket. While not quite up to the sprightly FZ-09 as far as overall power in the bottom half of the rev range, the Kawasaki towers over the GSX-S750 when it comes to response from the engine room. Power continues to build as rpm rises into the five-digit zone before tapering off slightly as the Z800’s engine approaches its rev limiter around 12,000 rpm, but there’s enough top-end power to be had without revving it that far, and wheelies are but a clutch-snap away. The Z750’s steel backbone frame was revised with two bolt-on aluminum subframe sections that allow the Z800’s front engine mounts to be positioned behind the cylinders. While Kawasaki says this allows the vibration from the inline-four to be isolated more effectively, some vibes can definitely be felt through the handlebar and footpegs above 7,500 rpm. Nonetheless, the Z800 has a nice, neutral yet fairly agile feel in the corners, with only a little effort required to fl ick the bike into a corner. Line changes in midcorner are easily accomplished with zero drama, and the stock Dunlop OEM-spec D214 Sportmax tires display good grip and light steering characteristics. There’s plenty of ground clearance, and the standard KYB suspension components on the Kawasaki-a 43mm inverted fork (adjustable for spring preload on one side and rebound damping on the other) and single rear shock (also adjustable for spring preload and rebound damping)-provide good wheel and chassis control even when the pace heats up. The ride is a little firm for pothole-ridden urban tarmac and highway superslab but nothing drastic. Despite the budget-looking standard-mount two-piece Nissin calipers, the brakes work well. Response is a little fl at, but power and feel are surprisingly good, with the 310mm discs likely helping by providing good leverage for the calipers. And the standard Nissin ABS works well too, with a fairly high intervention point and transparent action overall. Probably a good thing, as those brakes need to slow down around 509 pounds with a full fuel tank; even though it carries that weight well, the Z800’s heft is our only real gripe with the Kawasaki. Ergos are average standard bike fare, with a slight sporty cant to your upper torso offsetting the windblast. At $8,399, the Kawasaki Z800 ABS is a touch more expensive than the non-ABS-equipped Yamaha FZ-09 ($8,190) or the Suzuki GSX-S750 ($7,999 for the base model). But its solid performance definitely makes it worth a look in the middleweight standard category.
