BMW Motorrad Patents Reveal New Carbon Fibre Chassis

Latest patent images filed by BMW Motorrad reveal the German brand's next-generation frame that does away with a conventional swingarm pivot, and uses flexible carbon fibre instead. Latest patent images show that the swingarm will be integrated into the main chassis, getting rid of a swingarm pivot. The idea is that carbon fibre can be engineered to be rigid in one direction and flexible in another, so the design will allow the swingarm to bend to absorb bumps, but will not allow any lateral movement that may affect stability. A conventional spring and damper will still be used, allowing for suspension adjustability.

The design isn't completely new or radical, and has been used in race cars, which used the flexibility of carbon fibre in their suspension designs. Without pivots where the wishbone suspension is attached to the chassis, provides both strength and stiffness, but also reduces weight and improves aerodynamics. Right now, it's just a patent design, and even if BMW Motorrad is considering such a design, it's confirmation enough that high-performance carbon fibre frames for motorcycles is very much under development, for some future models.

In fact, it's not really a first for BMW Motorrad. The German automotive giant has already proved that it's a pioneer of the carbon fibre motorcycle chassis, which is already available in the very expensive, and exclusive, track-only HP4 bike. A future BMW S 1000 RR is almost certainly going to get a carbon fibre frame, perhaps sooner than expected. The patents aren't confirmation that a carbon fibre chassis is ready, but there's no doubt that BMW will leverage its experience and mass manufacture using carbon fibre components to trickle down to a carbon fibre-framed future motorcycle.

Brixton 1200 To Rival Triumph Bonneville T120

Image
A 1200 cc modern classic with similar design lines as Triumph's iconic Bonneville series, has reportedly been cleared for production. The bike was showcased as a concept at last year's EICMA motorcycle show, and from the looks of it, this is a model developed in China with the Triumph Bonneville T120 in its sights. The Brixton brand though is part of Austria's KSR Group, which imports bikes from several Chinese manufacturers, including CF Moto. And while the new Bonneville rival will be manufactured in China, the design and engineering has been created at KSR's design centre in Krups, Austria.

Zongshen Cyclone RX6 Based On Norton 650 Nearing Completion

Image
While there still doesn't seem to be a buyer for iconic British brand Norton Motorcycles which went into administration in January this year, the firm's 650 cc parallel-twin seems to be finding life in China. While Norton apparently sold off the engine rights of its 961 engine to China's Jinglang just before the brand went into administration, the deal for the 650 cc engine was finalized way back in 2017 with Chinese giant Zongshen. The 650 cc parallel-twin engine was due to be used in Norton's Atlas and Superlight models, but now it looks like that engine platform will make its debut in a Zongshen motorcycle, called the Cyclone R6.
