Is anyone else following Soviet Steeds on Facebook, where Mike M. Paull posted about the failed piston in the 2022 press bike on their tour in Argentina? I wonder if this is going to be a problem that Ural are going to need to address on the new bikes with regards to the higher compression they are now running. I can see an off-road map coming!

Yes following the same. He post also on Ural owners page. So, 2 sets of comments to review. I have made comment to him on both sites asking for more info. This is not the first time either. The first was before release here or the US and was attributed to low grade fuel. Ural then advised they had altered the map to prevent a reoccurance. So, if this is the "press bike" it may be one of those early ones. He said he didn't know why, but is returning the holed piston to Ural for analysis. Watch for other developments.

Occurred because too hot or too lean, could be too hot because too lean, or pinging also because too lean / too much timing.
Ural will act on it and release a fuel map / timing update if need be. It’s been done before.

As I mentioned. It has occurred before on the 2022. They did a remap prior to release here and the US.

Assuming this bike had the new map - as you expect if it’s their own press bike - Maybe they need to do some tweaking and release another one! :-)

These are the operating conditions reported by the author in previous posts. They are on Route 40 in South America. Temperature are around high 90F ie 35C. Elevation is up to 14000' or 4200+ metres. They speak of holding 60mph 90kph when possible. In the mountains mostly 2nd and 3rd gear. The authors 2021 GEO (lower compression) is coping well. I'm betting the fuel is sub standard and the 2022 suffered. Just my 2c. I did ask the author to reply with an idea of what fuel they were using. I don't expect a reply cos they would give Ural the best opportunity to remedy matters.

More info from the author. In response to fuel type " whatever we can get and its not unusual to be waiting 20 minutes to fuel up" To be fair, this is a guess. So let's not get too carried away. To put this into context. A fair while back, when Adventure Biking began, BMW released its first 1150cc ADVENTURER. I had one for many years. NO kickstarter and demanded minimum octane of 95Ron and 98 if you can get it. You could buy a plug in module to take crappier fuel. I used octane booster. Good old "Wynns" So,what we are seeing here is not new. Only new customers paying a price for being unprepared. Mine was 2001/2 I think. First GS ADV Series in Australia. What is NEW, is ever tightening EPA rules around emissions and sound. To meet Euro5 required significant changes. One was leaner fuel mixtures It's what we're dealing with now.

My 2022 would occasionally ping early in the piece, mostly could be heard on the LHS rattling up from the sidecar. solution was change down and climb hills slower, lower speeds at bottom of hills [run in] did not help. Certainly my riding methods had to be modified to account for high vehicle weight and modest available power but I am certain any tendency to ping is diminishing as mileage increases, I can now ride consistently at 90 to 100k on open back roads pretty much much without changing down for hills. I run 98 RON, bought a half litre of Nulon octane booster ex Sparesbox for $19.00, Nulon claims "up to" 7 points RON improvement, independent testing indicates 3 to 3.5 which would still help if forced to use standard unleaded. Half litre bottle will treat 60 litres if used as recommended.

Ural really needs to address this requirement and provide an option for reducing the timing or richening the mixture a la ‘Offroad map’ in years past. Carrying litres of Octane booster into the outback really doesn’t cut it.
It’s the least of their problems at the moment though! It is eerily quiet on social media, and this forum….anyone else notice?
