This year there was the zero emissions TT race - the TTXGP race on the 37.73 miles Mountain course on the Isle Man.
Now there are plans in Denmark to run the first-ever, environmentally-friendly, electric-powered off-road enduro during the period of the United Nations Climate Change Conference in Copenhagen in December.
The International Eco Enduro will be based on the type of long distance off-races we know as enduros and will run over a series of races between December 8-13.
The races are organized by the Danish Motor Union ( a member of the FIM) and last weekend, Danish motocrosser Brian Jorgensen (a former British motocross championship regular), did the first demonstration-run on a Quantya electrical MX-competition bike during the Sidecar World Championship in Slagelse, Denmark.
Jorgensen said: “It’s a strange feeling, not to hear anything, but also a good feeling to know, that it is possible to drive without disturbing anybody with noise and without any sort of exhaust gasses let out in the atmosphere.
"I believe in environmental friendly motorsport and will be happy to take part in the International Eco Enduro in December.”
