Royal Enfield Spain have just unveiled a new stunner in their line-up, courtesy Jesus de Juan. The custom bike, a Classic 500 is named as Green Fly, which Juan made taking inspiration from Dirty Duck. In June 2016, Dirty Duck had showcased a custom off-road inspired Continental GT model.
For the Green Fly, Juan customised a Royal Enfield Classic 500 making it into an off-road motorcycle on a Continental GT frame. 
The Green Fly gets a new pair of suspension system with mono shock on the rear in place of dual springs and upside down forks in the front. 
Moreover, the Green Fly gets off road knobby tyres which measures 140mm for the front tyre and 150mm for the rear tyre. The tyres are placed on a pair of green alloy wheels. 
However, the engine specs are not revealed, but it seems, that the Green Fly will come with tuned-up performance, which makes it more torquier and overall increase in power output.
