Downloaded the owners manual from Norway and was browsing through it last night. Noticed that it said for cold tires, inflate to 33psi (up to max weight capacity).
However, on the tire itself, it shows 41psi.
Is that variance based on the tire (I have Avons)? Or is under-inflating recommended for a particular reason?

Lower tire pressures on these beasts we drive result in cupping and premature wear. The exception is if your are running rear D/S. On a D/S application pressures in the mid 30 P S I ranges seem to work better. On my I/S front tire P S I is 42 to 43 P S I. Your results could need adjustments for your sweetspot.  Hope this helps some. DO NOT forget to ask about what oil to use.   RIDE SAFE. |

Avon used to state lower than this, but there's an Avon web site somewhere I've seen that shows that Avon is on board with the above range for Valkyries and their Cobras. -Mike |

Since a tire can be used on multiple vehicles, the max inflation pressure on the tire is just that...max pressure recommended by the manufacturer for that tire. The pressure recommended in the manual, or on the stickers on the door jambs in your car, are what the vehicle manufacturer recommends for that vehicle.
The pressure you run is up to you, but what Joevalk (and probably others by now) posted about lower tire pressure and cupping is pretty well known by most Valk pilots. There's also a ton of tire pressure info (arguments? opinions?) available by using the search function on the board(s).

Thank you Tony! I don't know how many times I have typed those same(almost)words on this forum, but the info just doesn't seem to "stick".

I have Avon Cobras (my 2nd set). I've run 42F and 46R. The current rear has 19+k miles and I can't wear it out yet. Still has tread. I drive mostly freeways at 70+ MPH.

Honda recommends 33 psi but I believe they do that for a softer more comfortable ride rather than mileage. Go with what the experienced members have posted, no lower than 38, more is probably better. Mine rides like a lumber wagon at the higher pressures but if it provides more miles, I can stand the ride.

Here's an Avon web page that specifies a suggested pressure for Valkyries... it is a giant PDF... you can use the PDF search tool (not your browser's search tool) to go right to the Valkyrie info... http://www.avonmoto.com/download/Avon_mc_databook_2012.pdfThey say 40 psi for both. I remember once, on a chilly day, checking my air pressure before I left home, and then again 40 minutes later... they'd gained 5 or 7 psi after heating up... -Mike |

Since I am a solo rider most of the time, and a light weight, I use the recommended pressure. More weight, more pressure, simple. Just like adjusting your truck tire pressure for whatever you are hauling. Hoser |

Recommended tire pressures are listed for "Cold"(ambient temp) tires. After a tire warms up, it should increase 10 - 11%. You may have to experiment with the starting psi to get the correct number that gives you that 10 - 11% increase for your load, speed, and riding style. |
