2022 new Multi Cylinder World Altitude Record - 6,157m

Top Spanish trials rider Pol Tarres, has been heavily promoting the Yamaha T700 adventure bike this year, even riding one in the Africa Eco Race, a rally that follows the original route to Dakar, had earlier in 2022 become the first rider to take a twin cylinder bike above 6,000 metres on Cerro Mercedario in the Argentine Andes, ultimately reaching 6,157.5m (20,202 ft) to update the multi cylinder bike world mark and take it from the Africa Twin mark from 2017. Pol looks like he was using oxygen to assist acclimatization.

A video of the attempt is also below - he literally rode up the side of the mountain from about 3500 metres up.  I have no doubt, that if he had attempted this at Ojos del Salado and if he knew the correct route to take there, he would have an world record for all motorcycles.

2020 World Moto Altitude Record - 6546m

As part of Urs Pedraita's Grizzly Race Team, Swiss rider Jiri Zak on a Yamaha reached 6,546m (21,476 ft) again on the slopes of Ojos del Salado in Chile in February 2020, overtaking the 6,472m (21,233 ft) outright motorcycle mark previous held by Chileno Gianfranco Bianchi.  The Guinness World Records folks have verified and confirmed the record.

Zak's effort peaked about 70 metres (200 feet) higher than the previous mark set in 2015 by Chilean Gianfranco Bianchi, who was himself about 80 metres higher than we achieved in 2012 (6361m).

[just my personal opinion but having been to the mountain, ridden up it, and knowing the possible vehicle routes and contours, it seems to me that 6690 / 6700 metres is definitely possible at Ojos del Salado. That means there are more records to come from that location and this will not be the last. The main factors are preparation and acclimatization - then once fully prepared and acclimatized you have basically one shot at the record as your body weakens from the altitude before you need to go back down to near sea level to recover.  If Graham Jarvis wants a world record, its there for the taking]
