Yamaha ' s R3 bLU cRU series is upgraded to FIM World Cup Status for 2024 . The FIM Superbike World Championship ' s feeder class and previously known as the Yamaha R3 bLU cRU European Championship , has been upgraded to World Cup status and will now come under the global FIM umbrella . Launched in 2021 by Yamaha Racing it is designed to provide a structured and direct path into world championship racing for riders aged between 14 and 20 years old . Managed by Japan Italy Racing ( JiR ) and supported by the FIM and Dorna WSBK Organisation ( DWO ), the series forms an integral part of DWO ' s SBK Roadway program . This partnership between all parties has proven to be an effective and successful one , with a large percentage of the FIM Supersport 300 World Championship grid now made up of former bLU cRU riders . This new World Cup will be contested across 12 races at six European rounds of the 2024 FIM Superbike World Championship , and the overall champion will earn a supported ride in the 2025 FIM Supersport 300 World Championship provided by Yamaha Motor Europe .
A new CEO often does mean a change of direction and after what is generally regarded as a less than positive two-year experiment in Berlin , BMW Motorrad has announced a return to Garmisch- Partenkirchen for its BMW Motorrad Days ' Brand-Fest '. Slated for 5 to 7 July , the volteface is described as " a response to the heartfelt desire of its fans all over the world for unadulterated motorcycle culture , a party atmosphere and unique riding experiences against a breathtaking Alpine backdrop ". With its 100th anniversary celebrations now firmly in the rear-view mirror , " what better location for the " Year of the GS " than Garmisch-Partenkirchen with its magnificent surroundings , winding roads and nearby alpine passes . It is the ideal terrain for unique motorcycle rides especially with the legendary icon of adventure riding " states the BMW PR team ! Indeed . Although some 80 % of the KMs ridden by most all ASDV bikes are actually urban , congested downtown traffic and parking hassles aren ' t really the image they want to be identifying the GS with .
Almost every electric motorcycle is direct drive - the motor is permanently geared to the rear wheel via a single ratio - so there ' s no need for a clutch or gear shifter . But American EV pioneer Zero is considering adding a false clutch lever to its electric bikes to give them an extra dimension of controllability . While the purpose of a clutch is simply to disengage drive from an engine to the transmission , so you can come to a halt without stalling , and to shift gears smoothly , in reality , riders use that lefthand lever in a much more subtle way . It ' s as important as the throttle , or even more so , when it comes to deciding how fast you get off the line when the lights go green . It ' s used to moderate the amount of engine braking at the rear wheel when you downshift and can be invaluable in giving fine control during low-speed manoeuvres . When an experienced rider gets on an electric bike for the first time , it ' s the lack of a clutch lever , more than anything else , that is initially jarring . While electric motors offer vast torque at low revs , without a clutch , you ' re at the mercy of a pre-programmed torque curve and throttle response map when it comes to
getaways , and changing the amount of regenerative braking available often means delving into the depths of menus hidden in the dashboard ' s user interface . Zero ' s new idea , revealed in a patent application from the company , is to use a control that looks , feels and operates like a clutch lever , but doesn ' t actually involve fitting a real clutch between the electric motor and transmission . Instead , the lever will operate a rotary sensor that alters the amount of torque reaching the rear wheel , or back-torque from regenerative braking when the bike is decelerating , to mimic the response of a clutch . Pull the lever in and the power and torque to the rear wheel is cut , even when the throttle is wide open . Release it again and the

Benda Napoleon 250 revealed By Ben Purvis

Benda is another of the many Chinese bike companies that are looking towards the global motorcycle market with exports to Europe and the USA , but it stands out from the competition thanks to innovative and unusual designs . The brand came to prominence as the first Chinese bike maker to launch a fourcylinder machine a couple of years ago in the form of the LFC700 musclecruiser , followed swiftly by the more conventional LFS700 , using the same engine . It followed those with the Dark Flag 500 , the first Chinese bike to have its own homegrown V4 engine , and most recently impressed with the Napoleon 500 , a V-twin bobber with exotic styling and a faux girder fork at the front . Now there ' s the Napolean 250 , also packing a V-twin and sporting bobber design cues , but with a smaller engine and yet more innovation in the form of unusual front and rear suspension
designs . Official specs are thin on the ground , but the bike has been type-approved in China , revealing a peak power of 19 kW ( 25.5 hp ) from a Benda-built 249 cc V- twin . It sits in a steel frame with a relatively long 1,545 mm wheelbase and an all-in weight of 182 kg . The styling follows the Napoleon 500 , with a similar single-seat layout and retro-inspired proportions . However , where the larger bike uses upside-down telescopic forks hidden behind cowlings , giving the impression of prewar girder suspension , the Napoleon 250 ' s front end combines elements of both telescopics and girders . The main part of the front suspension is a pair of normal , right-way-up forks , but there ' s an additional casting mounted on the fork lowers , with extra external spring units on each side . Whether these are functional or simply cosmetic , like the larger Napoleon ' s fork cowls , remains unclear at this stage .
torque is returned to the wheel . That means riders with years of ingrained experience of balancing throttle and clutch controls will be able to get the same response from an electric bike , using the ' pseudo-clutch ' lever alongside the throttle . It ' s not just useful for the sake of familiarity , though , as it gives the ability to control the throttle mapping on the fly in a natural , instinctive way , and perhaps more importantly control the amount of regenerative braking on the rear wheel without switching between modes . And with relatively few additional components - most of the changes are software driven , not hardware ones - it ' s a system that shouldn ' t add substantially to prices .
The rear suspension is also unconventional . The triangular swingarm matches the angle of the main frame ' s upper rails , giving the proportions of a hardtail , but there ' s a coil-over shock on each side connected to an unusual rising-rate linkage . Most cruisers in this capacity class make do with very simple twinshock rear suspension , not to mention parallel twin engines rather than V- twins , so it ' s surprising to see something so sophisticated on such a small bike . With other Benda models already available in several European countries , and NHTSA documents already filed in America , that indicate the company is entering the North American arena in 2024 , there ' s a strong chance the Napoleon 250 will be a global model once it gets its full unveiling later this year .
