Delfast Dnepr Electric Motorcycle Sets Record at Bonneville Speed Week 2021

General Posts / By

by Cristian Curmei from https://www.autoevolution.com The current electric movement is extending further than anyone may have previously imagined. One company pushing electric speed limits is Delfast with their most recent speed record setting action at Bonneville Speed Week 2021. If you haven’t heard of Delfast yet, it’s time to catch up as this team is breaking all kinds of barriers. Since the Ukrainian-based manufacturer of e-bikes set a Guinness World Record for “Longest Range” back in 2017, the company has fallen under the attention of many a circle, even providing their EVs to police forces around the world. Their most recent achievement, and one worth the attention, is their newest speed record achievement at Bonneville. Now, they did go out there with an e-bike, but alongside said e-bike, with an electric motorcycle based on a previous Bonneville visitor, the “Dnepr Electric” motorcycle from back in 2018. This bike set the record at 104.78 mph (168.62 kph) in the “A” Omega category. The rider of the vehicle back in 2018 was Serhii Malyk, a Ukrainian racer and multiple title champion that just so happens to love hanging out at Bonneville and kicking up salt on just about anything that’s fast. Ever heard of Dnepr? Well, this Soviet-ran manufacturer’s history began before WWII. However, it wasn’t until 1952 that the company ran full steam ahead. With a design focused primarily on military use, these puppies are still found today, some still sporting the sidecars of their time. What really brought fame to this brand was their attempt in copying an existing motorcycle design, the BMW R-71. Without any apparent documentation, Soviet engineers decided to copy the BMW model. With a 22 hp engine, four speeds, and shaft drive, the Soviet’s named it the M-72. Well, a most recent acquisition of the Dnepr

WMC Electric Motorcycle Aims At New Speed Record

by Daniel Patrascu from https://www.autoevolution.com WMC Electric Motorcycle Has Big Hole in It, Only Way to Set New Speed Record. There’s a good chance the name White Motorcycle Concepts (WMC) doesn’t ring any bells. Don’t worry, that will probably change as soon as next year, provided the company achieves its goal of setting a land speed record for electric motorcycles. WMC is a British engineering company set up not long ago by British Formula One engineer Rob White. Its goal is to advance the adoption of electric drivetrains in the motorcycle industry not by coming up with some incredible battery or electric motor but by devising new aerodynamic tech that should better use the available power. The tech in question, called V-Air, was inspired by the cars taking part in Formula 1 or Le Mans. It consists of a large duct at the center of the bike, in essence, a big hole running through it, designed to force air through the two-wheeler and not around it. This, says WMC, reduces aerodynamic resistance by as much as 70 percent compared to an unnamed “market-leading high performance road bike.” V-Air is backed in the demonstrator motorcycle, called WMC250EV and unveiled on Wednesday, June 23, by a motor driving the front wheel and coupled to a regenerative braking system. There’s an additional final drive system on the bike, one that, according to the company, will not only boost power and enhance efficiency but could also be easily adapted for existing motorcycles. The demonstrator will be put through its paces starting later this year, with White himself planning to mount the bike and race it around. The highpoint in the development of the V-Air is a run planned for next year on the Salar de Uyuni salt flats in Bolivia, the largest of its

Customised Royal Enfield 650 Interceptor sets speed record

General Posts / By

by Phil West from https://www.motorcyclenews.com Who said Royal Enfields weren’t fast? Not Mid-Life Cycles, the dealer behind this special Interceptor 650 which recently posted a record 132mph at the Australian equivalent of Bonneville Speed Week. Called the Sabre, the machine is based on a 2019 Interceptor 650 but puts out around 70bhp (up from 47bhp) and has been built to show the bike’s potential and as a test bed for parts and accessories to be offered to the public. Created to conform to the ‘M-F 650’ class, an unfaired, production-based formula, the intention was to compete at 2020’s Speed Week at Lake Gairdner in South Australia, a salt lake similar to Bonneville in Utah, USA. The pandemic scuppered those plans – until now, as rider Charlie Hallam posted a class record of 121.78mph first time out before gradually setting a new standard of 132.05mph. Not bad for an air-cooled, OHC parallel twin displacing just 648cc. The engine has, of course, been heavily reworked, by specialists HRA Geelong. Although capacity is unchanged, as per the rules, the crank has been balanced, rods shot-peened and new pistons added to help raise compression to a heady 11:1 requiring 98 RON fuel. Head and ports have been modified to flow as much fuel as possible and there are special custom valves while the single camshaft is now HRA’s ‘Competition Profile 1286 Racing Camshaft’. Open race pipes exit each side, the transmission’s gears were recut to reduce friction and special sprockets were made. Although the frame is stock, the swingarm has been lengthened to the maximum permissible, suspension replaced by Öhlins front and rear, wheels are lighter, wider alloys, and ultra low clip-on bars and a more aerodynamically efficient front mudguard were fitted. Now the plan is for Mid-Life to offer performance and big-bore kits

British engineers will try to break the 376.3mph motorcycle record in a 30-ft-long vehicle

Engineer and ex-racer Alex Macfadzean, 77, and his team designed the ‘streamliner’ bike which will make its record attempt next year at the Uyuni Salt Flat in Bolivia. Behind the wheel will be motorcycle racer turned TV presenter Guy Martin, who will attempt to beat the current record of 376.3mph and cross the 400mph threshold. To try to advance the record, Mr Martin will run the new streamliner on a mile-long course twice in opposite directions, as per official land-speed record rules. The bike’s 1,200 shaft horsepower Rolls Royce engine is the same found within the Westland Lynx helicopter once employed by the British Army and the Royal Navy. The first official motorcycle land-speed record was set in 1920 by the American racer Gene Walker 103.5mph, building on unofficial efforts dating back to 1903. Britain last held the record for six months in 1937 after Eric Fernihough broke 169.72mph on his Brough Superior-JAP. But Italy’s Piero Taruffi took the title by an extra 3.31mph in the October of 1937. The title has changed hands
