The concept of a naked bike powered by Hondas Super Blackbird engine had seemed enticing ever since the ultra-fast 1137cc fours release in 1996. When the X-11 finally arrived three years later, it did so at considerable speed, if not quite with the style that had done so much to popularize unfaired machines from firms such as Ducati and Harley-Davidson.

Plain but entertaining

In contrast to the best of those bikes, the X-l 1 was rather a plain-looking creation. Its liquid-cooled engine was partially obscured by a large grey plastic radiator shroud that had been added in an attempt to make the X-11 more stable than the average naked bike at high speed. But if the big Honda lacked a little in visual appeal, it certainly was fun to ride.

This bike was much more than simply a stripped-down Super Blackbird. Honda detuned the 16-valve engine with revised fuel-injection and a new exhaust, reducing peak output from 150bhp to a still impressive 134bhp at 9000rpm. Other changes include a single instead of twin balancer shafts, and a five- instead of six-speed gearbox.

The frame combined the Blackbirds twin aluminium main spars with a new cast central section at the rear. This was used to mount the swingarm, and was designed to introduce a small amount of flex into the frame. According to Honda, this gave the rider more of a feeling of slowly settling into corners.

Honda also claimed that the radiator shroud not only helped feed the airbox but also created

downforce on the front wheel, increasing highspeed stability. The small plastic instrument surround was also intended to divert wind from the rider at speed. All of which sounded improbable... until you actually rode the X-11.

There was enough top-end power for a maximum speed of 160mph (257km/h), and by naked bike standards the X-11 was superbly efficient at such velocities. Perhaps partly due to its radiators downforce, the Honda remained rock solid when most unfaired bikes would have been verging on instability. Even the little instrument cover diverted enough wind to allow fast cruising in more comfort than on most unfaired machines.

Despite its size and weight, the bike was reasonably low, as refined as any Honda and really quite manageable at slow speeds. Its big four-cylinder engine was notably torquier and more responsive than the Super Blackbirds. Inevitably the X-11 didnt have the faired bikes thrilling top-end power rush, but in most situations the smooth surge of acceleration from low revs was very ample consolation.

For a big bike the Honda handled very well. Its steering was reasonably light, and the fairly basic suspension gave a firm ride while soaking up most bumps. The linked brake system, a tuned version of the Super Blackbirds Dual-CBS set-up, combined plenty of power with a reassuringly normal feel. Most people who rode the Honda loved it. The X-11 might have lacked the style of some naked rivals, but it was as fast and exciting as any of them.

2011 Zero X Press Release

PRESS RELEASE

ZERO MOTORCYCLES ANNOUNCES 2011 PRODUCT LINE WITH COMPREHENSIVE UPGRADES AND A QUICK-CHARGE OPTION ACROSS ALL FOUR MODELS

- Highly Refined New Motorcycles, A Solid Business Strategy, Support and Availability in March -

SANTA CRUZ, Calif. (February 8, 2011) - Zero Motorcycles today announced its highly anticipated 2011 product line alongside a strategy for continued leadership of the global electric motorcycle industry. The only company to offer a complete lineup, Zero Motorcycles has made sweeping technical improvements as well as added a contemporary new look to each of its four models, including a complete overhaul of the Zero S and the Zero DS. Every model is now ‘quick-charge’ capable using an optional upgrade that allows the motorcycles to charge nearly twice as fast. In addition, for the first time on an electric motorcycle, riders can now take advantage of J1772 public charging stations by using an optional accessory. This offers riders greater mobility by giving them access to a rapidly growing network of charge stations. The entire lineup is equipped with upgraded suspension systems, a more intelligent and rugged Z-Force powertrain, more precise charge indicators, new higher performance brakes and industry-standard component features to provide owners with more aftermarket options. Other highlights to the product line include street legal configurations of the dirt bikes and a new maintenance free belt drive for the street and dual sport models.

“During the past year, our Engineering and Manufacturing teams have benefitted from experienced new leadership and the results are clear. In close coordination, they have been working overtime to design and build the world’s finest collection of electric motorcycles,” said Gene Banman, CEO of Zero Motorcycles. “Our 2011 model line is composed of exceptionally high quality electric motorcycles that balance performance, range, weight, affordability and availability. We are excited to announce such major changes across the entire model line and to also be setting new industry standards in the way we report on our motorcycles’ performance specifications.”

Nearly every component of the Zero S and Zero DS has seen major upgrades and improvements. With a bold and completely new look, the street and dual sport models will become the world’s first production electric motorcycles to feature a maintenance free belt drive system. The quiet operation of the drivetrain, when combined with each of the motorcycles’ overall improvements, yields a sophisticated silence during riding that speaks to their overall solid build quality. Zero has also increased the capacity of the power packs by 12.5% to improve the motorcycles’ range. Among the other upgrades are more robust wheels, a new HB Performance braking system, tires with better grip, more robust hardware, new aggressive profile foot pegs and an integrated ignition switch and lock. Unique to the Zero S, it has been lowered by two inches to improve street handling and the new overall package gives it an eye-catching naked look.

Zero Motorcycles has also made major changes to its off-road line. For the first time, the company will deliver street-legal configurations of both its trail and motocross dirt bikes, Zero X and Zero MX respectively. The ability to legally ride the electric off-road motorcycles on the street opens countless new possibilities for enthusiasts as well as a new market for Zero. Street-legal versions include additional components such as headlights, taillights, side stands, dashes, sensors and different gearing.

Both the Zero X and Zero MX are better performing and more robust than ever before. They have stouter wheels, new tires, a more robust HB Performance braking system, new aggressive foot pegs and an integrated ignition switch and lock. Their motors are energized using a beautifully refined aluminum power pack that is highly durable and easy to swap in less than sixty seconds. To maximize control, Zero has customized each motorcycles’ suspension internals to give them a more fluid and compliant motion under rough conditions. Unique to only the Zero MX, the 2011 model uses a motor mounted Z-Force Air Induction System to cool its new and more powerful Agni motor. Designed to ride harder, faster and longer, it represents the most competitive dirt bike that Zero has released to consumers.

The Zero S, Zero DS, Zero X and Zero MX are all available now through Zero Motorcycles’ website and will begin shipping in March. Each of the models carries a two year limited warranty. This is currently the best warranty offering in the electric motorcycle industry and is backed by an international service and support network.
