Stark gets Guinness altitude record

One place where battery bikes will always outperform ICE machines is on high mountain passes. While petrol bikes struggle to run with reduced oxygen, the lithium-ion machines go even quicker thanks to thin air and cool temperatures. Electric dirtbike maker VARG took advantage of this at the end of last year, running a standard unmodified VARG EX to 6721m on the Ojos del Salado mountain in Chile. The achievement has earned the firm and Swiss rider Jiri Zak a Guinness World Record for the highest altitude ever achieved by a motorcycle.
