2018-20 RMK 800 x 155 compared to SKS 800 x 146

So I'm busy looking at hold over sleds and comparing a Pro RMK 155 listed at 408 pounds and an SKS 146 listed at 460 pounds.
Wow, what a difference! Has anyone had both of these sleds together and done a side by side weight comparison to measure the "true" weight of each?
I've looked at them and studied the changes that are obvious but 52 pounds??? Can see 25-30 lbs but not 52.
Thanks for any input

Additional bulkhead cooler, chaincase with steel gears, steel drive shaft, torsion rod skid and larger fuel tank will definitely add up.

For some reason I think the 146 SKS is listed with electric start that is why

The 146 is based off an switchback and not rmk...

wish they would of shortened a 155 to build it. And give it a snowcheck option for a little more lug to make it comparable to the doo....

I shortened a 2014 Pro RMK to a 146 with Ice Age rails and got a 2.4" Polaris track.
Was actually a pretty easy project, I think I cut 6" off of the tunnel & coolers.
Toughest part was welding the cooler cross over pipe at the end of the tunnel. Would be even easier if I did it again.
I guess if I want a lightweight 146 this is the way to go!
