Arc-VectorAnnounced at last November’s EICMA show in Milan, the £90,000 neo-café racer will enter full production at the end of 2020 with 399 units to be built to order in the first 18 months.
This revolutionary electric motorcycle boasts Human Interface Technology, state-of-the-art carbon monocoque and swing arm, ground-breaking hub-centre steering, power-dense battery cells, bespoke brakes and suspension, and race-inspired wheels.
Founder & CEO Mark Truman, the visionary engineer behind Arc, has undertaken the lion’s share of track testing himself at circuits and airfields around the Midlands, fettling the finer points of the Vector’s geometry and handling. A notable design direction has been hub-centre steering. For the Vector, we’ve created a system that has all the benefits of HCS but which feels like a set of forks. The advantage is stiffness which allows for a steep rake angle and a chassis that enables fast changes of direction with stability at high-speed. What we’ve devised is the best of both worlds with none of the negatives.”
The philosophy when it comes to handling is to balance performance with control. It’s an agile motorcycle with plenty of power, but it’s designed to be user friendly and fun to ride both in town and on the open road. It’s a bike designed for life more than racing.
Another rarity that Mark’s team has embraced is the belt drive, which guarantees low weight and low maintenance. It’s also quieter and smoother than a chain drive, and owners will never get oily hands.
Arc’s technical partners represent the best of breed. The Vector’s brake discs are Brembo and the calipers are their Stylemas, but bespoke in black oxide. The Ohlins suspension is entirely customisable, and the unique BST wheels are as light and strong as a pro race bike’s. Anti-lock brakes have been provided by Continental, Pirelli have made the tyres, the battery package is by Delta Motorsport.
In addition to handling, a lot of development has been done on the powertrain with battery cell suppliers Samsung and on the dyno and the track in order to coax out every last drop of performance. The cutting-edge Samsung 21-700 batteries, of which the Vector packs a vast 960, are some of the most energy dense and reliable cells on the planet and the Arc Vector is the first motorcycle to use them.
With a 399-volt electric motor producing 133bhp and a weight of 220kg, the Arc Vector will have the best power-to-weight ratio of any electric two-wheeler – 650bhp per tonne. Combined range will be around 270 miles. Zero to 60mph will arrive in three seconds and the top speed will be 125mph. No clutch, no gears, just you and the open road. Massive torque, traction control, ABS brakes, variable dynamic modes and ingenious Heads-Up Display and haptic alert systems make the Vector riding experience unique, safe and utterly euphoric.
Having prototyped the Vector in Coventry, Arc is targeting expansion to a 65,000 square feet HQ in St Athan, South Wales, in 2020.
