What's the highest you've seen on speedo with a 1,25 track?

205 km/h on speedo, on spring ice, +12 degrees Celsius jetted for -20. On gps, hard packed trail on a 10 degree day, 113 mph, again jetted for -20.
Today I got 118 mph on speedo with that 1,25 track.
-2c.

ok guys i run sleds for years how can you read a speedo going 118
Run it on the river. It's usually quite smooth. Find a nice loooong stretch.

if I didn't blow my track on the SRX I would be wrapping the needle around on the River right now... 
But in 2008 on a nice smooth River..basically Ice..I was reading 118 on my speedo..easy to watch actually when there is no bouncing going on and my head tucked to the dash.

X2 - I can expand the display to about a 1" digit on my Garmin III and still have to wait 'til I stop to read recorded max speed. On a flat bay at least two miles long.
Plus the speedo is useless for actual speed beyond 30-40 mph... according to my GPS. At those speeds I can read the difference.
Admittedly I'd be considered an old man these days but I don't remember being able to read the speedo much above 60/70 mph without guessing. Once I started using a GPS and found how far off the speedo is I just never bothered looking anymore.
All those years I thought my 500 Indy could do 90... LOL.

I know my speedo was 4 mph off at 100mph with my radar gun..still at 120 mph on speedo would give me around 112 actual...fast enough

120mph on the DM, actual speed was 113 on gps, that was on a 2000' run on a logging road.

there you go..see..!! I know there is a way to modify the gear for the speedo to get the speed pretty dead on...does anyone know the process for that off hand.

i only know how to do it on my rx1
I have no problem reading the speedo up over the century mark[maybe its a Canadian thing! LOL!!!] but as has been stated, the actual speed only counts on GPS or Radar. The dreamo meters just vary way to much to be counted in real speed discussions.

Very true my vmax4 speedo reads 118 when gps says 106

Must be all that fresh air up there... God's country ya know, eh? LOL.
Aside from the speedo calibration, I'd guess track spin plays a role... Except maybe on asphalt.

What surface are you guys on when you get these speeds? I could only squeeze out 160 km/h from my 02 srx on hardpack snow. I must have some serious problems with it, hope I didn't buy a dud.
