Chartįrom Stilletos To Phantoms and In-Between The TTXGP will use the same winding 37.73-mile course as the famed Isle of Man TT race, where riders maintain an average speed of more than 120 mph and navigate more than 200 curves.What Year Is My Ossa? - Ossa Frame Number I.D. Mission Motors is shooting for 150 mph from a 3-phase AC induction motor and a liquid-cooled lithium-ion battery with a range of 150 miles.Įnsuring the bike has enough juice to finish the race will be the biggest challenge. It will do zero to 60 in 3.8 seconds and, depending upon the gearing, as much as 135 mph. Still, Hussein says his 364-pound TTX uses lithium-phosphate batteries. "This is a very competitive race," he said. He doesn't want to tip his hand to the 40 or so other teams. And though Evo has some performance benchmarks it is shooting for, Simpson won't share them. Without knowing what kind of batteries they'll use, Simpson says, it's impossible to say what the bike will weigh. The motors are from Green Motorsport, but Simpson's keeping mum on the specs and won't say why he's using two of them. "It makes a lot of sense."Įvo hasn't picked a battery supplier yet and won't offer any details on what might appear on the EV-0 RR except to say it will use lithium chemistry. Simpson says the design provides greater rigidity and stability under braking. Imme, a German manufacturer, used a similar design from 1949 to 1951. The forkless front suspension is a double wishbone design based on that of the GTS1000 that Yamaha produced from 19. It weighs about 44 pounds, but Simpson says the technology used to build it has advanced and he's confident the race-ready chassis will weigh considerably less. Honda used a monocoque on the on the 1979 NR500 race bike, and the current Ninja ZX-14 features an aluminum monocoque.Ī prototype of the EV-0 RR uses a monocoque manufactured a few years ago. Spanish motorcycle company Ossa produced the first monocoque motorcycle in 1967, and Peter Williams won the 1973 Isle of Man TT motorcycle race on the monocoque Norton pictured below. A traditional frame limits the placement of the battery pack and motors, so Evo opted for a monocoque that encloses the drivetrain like a shell. One of the biggest challenges is getting all the electric bits to fit and packaging them so the weight doesn't throw the handling off.
"We've really gotten a chance to get our hands dirty," Simpson said. The aesthetics came from motorcycle design house Xenophya, but almost everything else about it - beyond the motors and battery - are being designed and built in-house. Still, the EV-0 RR (Electric Vehicle, zero emissions, Road Race) is the first project the six-year-old firm has done on its own. The iconic British motorcycle company Triumph is among its biggest customers, and its five employees have worked on "everything from submarines to glass bottles," Simpson said. Like Mission Motors, Evo Design stands out for the depth of its experience.
"There are electric motorcycles, but no true electric sports motorcycles."
"It's a challenge to design something that doesn't yet exist," he said. Simpson, an avid motorcyclist and co-director of the automotive and motorcycle engineering firm Evo Design Solutions, said he was drawn to the race because of the engineering opportunity it presents. It plans to compete in the TTXGP and says the bike will be on sale next year. A San Francisco firm led by former Tesla Motors engineer Forrest North says its electric motorcycle can do 150 mph. He will showcase it at the TTXGP he's hosting June 12 on the Isle of Man, although it is not slated to compete in the event. British entrepreneur Azhar Hussein has an electric sport bike capable of zero to 60 in 3.8 seconds.
