Last year Norton showed three tentative designs for scramblers to house its planned 650cc parallel twin engine and surveyed potential customers to find their favourite. Now the firm has unveiled a more definitive drawing showing the bike that will be released at Motorcycle Live at the NEC in Birmingham in November.

It’s also revealed the machine’s name: Atlas.

To recap, the planned Norton 650cc parallel twin is effectively the front two cylinders from the upcoming 1200cc V4 superbike. It’s being designed, like the V4, with help from engineering experts Ricardo, and Norton has already done a multi-million pound deal to allow Chinese firm Zongshen to licence-build a version of the motor for its own future machines.

The twin will have a longer-stroke crank than the V4, accounting for the extra 25cc capacity per cylinder. Norton hopes that the engine will make something in the region of 100hp, positioning it a league above similarly-sized parallel twins from the likes of Kawasaki and CFMoto, and instead putting it closer to the larger, 799cc twin used in KTM’s 790 Duke and upcoming 790 Adventure.

Norton has already said it plans to use the engine to compete in the Lightweight race at the IoM TT, with hopes to debut in 2019, although it clearly won’t be in the scrambler-style Atlas chassis.

Eventually, Norton also intends to introduce a 170hp supercharged version of the parallel twin housed in a sports bike that will sit below the range-topping V4.
