Ok, it's whish-o-meter indicated but still impressive, look at the RPMs it's pulling. I assume it's got a PB80.

My 2015 grand touring would do 120kmh which is 75mph. Hard packed icy road. On the packed trail with a bit of loose it would do 110...almost 70mph. So on a short track with a clutch, I could see it happening. Take a long stretch, they are quick to 50 and after that it climbs slowly.

Safari:  Getting much the same top end speed on my two sleds with 600 Ace engines.  

 

My 2016 MXZ with the 600 Ace tops out around 70 to 75 on a long, flat, semi groomed trail.  

My 2014 Skandic with a 2018 600 Ace Engine and 2018 Clutches tops around 60 in the same conditions.  

Both have 6.9 Pilots with 6" Doolies and Rub Rails. 

The MXZ is fully studded with Woody's and has around ~1.2" high lugs.  

The Skandic has ~1.2" high lugs with automotive studs. 

 

I could probably get another 5 MPH by playing with the clutch, but why.  60 MPH in a Skandic is way beyond my comfort zone in all but a few situations.  When I ride with others with guys with Turbo's, they mainly spin and slide launching when the turbo kicks in, and rip up the trail.  They have a crazy top end but pay for it with a jerky ride at the bottom end.  

 

Love these 600 Ace sleds.  :- )

Great power plant and have ridden several times for 100+ mile rides. Not enough juice no matter what clutch kit in a 600 ACE to reach that speed stock! Top speed max 70/75 MPH on a good day. They are fun to ride and have plenty of punch for trail riding and utility use. Doo has another hit out of the park with this power plant.

IDK, maybe the guy is lying and the sled has more done to it than just the Cudney clutch set-up but if my eyes don't deceive me it sure looks like the speedometer hits 85 in the video??? My bone stock 600 ACE did around 72 mph with my 240 lb fat butt and the sled only had 2-3 hundred miles on it at the time / wasn't even broke in yet. Stock shift out is supposed to be 7200 rpm. In that video it looks to be tickling the rev limiter at 7,800 rpm. With a lighter rider and an extra 600 rpm I could see another 10 mph or so ???

These comparisons are as good as the amount of accurate data provided by the snake oil salesmen.

 

When you ask them for the real data to back up their claims, they either go silent and ignore you, or get angry and try to belittle you.

 

They take a sled with many miles on it, worn springs and clutch components, and compare that one to another one with brand new clutches or clutch components and go LOOK EVERYONE! This one with my kit is SO much faster!!!  :headbang

I don't think the video was posted by Cudney Racing.

Watching the video the speedo run appears to be on an icy road. I have seen 135kmh/85mph on the speedo on ice with a non studded track. Back off the throttle just a hair and it jumps down to 120km/75mph but doesn't feel any slower. As mentioned, great tight trail sled when speeds are under 60mph the majority of the time and deceptively quick to 50mph. I was always able to hang with much more powerful machines whenever straightaways were short.

I've owned several Ace 600's...120's and Renegades. Most have ran in the lower 70's to possibly 75 mph on a good day. However, I did have a 2012 Sport with TNT ramps that was faster than the others by a good 5 mph. It would haul my 6'8"/300lb body to nearly 80 mph on normal packed trail conditions. My wife said she had it "over 80" out on the lake, so I do believe that some run exceptionally well.

My Expedition Sport 600 ACE tops out around 65 mph.  The 154 track and low gearing probably slows it down a bit.

I saw 80 mph once on the speedo on my gade. It was cold, super hard trail conditions. No studs.
