Kawasaki Moves Further Towards Electric Motorcycling with new Patent

It’s well known that Kawasaki, Honda, Yamaha and even Harley-Davidson all see a future with an electric bike in their lineup. Kawasaki has probably been the busiest of the major manufacturers with their patents and they’ve just lodged another one – this time for a regenerative braking system specifically for motorcycles.

The issue with regenerative braking on motorcycles is that bikes have much less intertia than larger vehicles such as cars which use the technology to good effect. That means that when rolling off the throttle, the regenerative system can sometimes cause too much loss of speed – akin to actual braking. Earlier reviews of bikes from Zero Motorcycles in fact noted the unsettling feeling this produces although it has been improved over the years.

Essentially, Kawasaki’s system incorporates a variety of sensors that control the regenerative braking process. Just coming off the throttle slightly and the system doesn’t engage. Come completely off the throttle and apply the brakes and the system kicks in. The system also takes into account the lean angle of the bike for those naughty people who chop the throttle in the corners.

It’s not like this hasn’t all been thought of before of course with KTM, BMW and Zero – as well as others – taking these things into account. What is more interesting is that Kawasaki continues to investigate technology related to electric motorcycles. Previously they’ve filed patents for an electric motorcycle with batteries that could be quickly swapped in and out. Kawasaki has also filed trademarks for names such as Ninja E2 and Ninja E2R which may hint to an upcoming electric sportsbike.


Honda CRF1000L African Twin Patent Renders

Patent images of the upcoming Honda CRF1000L African Twin have surfaced just a few days after Honda teased everyone with the first images of the production bike in its red and black color schemed glory. The images give us a full look at the changes between the final version and what we saw of the True Adventure concept.

Up the front is obviously the new headlight arrangement. The biggest differences between the concept and the production version relatse to the rear of the bike – though that much was already discovered in previous patents. The production version will feature a split rider/pillion seat with an inbuilt height adjustment mechanism. The seat can be moved up and down with ease and as it does so, the front of the rider’s pew slides up the tank.

Earlier patents had indicated that the front fairing/cowling was a one piece unit, though that’s not to established looking at the latest renders – it appears the piece may split just under the twin headlights. While not really visible in the renders, the other major design feature of the reborn Africa Twin is its split airbox design. The airbox is split in two parts with one mounted either side of the headstock. What this means is that the fuel tank can sit directly behind the engine which then in turn not only lowers the overall center of mass of the Africa Twin, but keeps things narrow up front as well.

An image circulating on Facebook shows these patent renders and the images released from Honda a few days go merged together.

The CRF1000L has now been confirmed for the UK, Europe, USA, Canada and Australia with devilries starting as early as this year.
