1977 Rupp Nitro 440

[@RJSerp]

Wow! Hearing that brought back memories of my Dad's Rupp snowmobiles in the 70s! Nice resto, beautiful sled!

Owned a '73 Rupp Magnum.. mint condition. Took it to shows. Super fast sled. Had temp guages for both cylinders..free air.

Had a Rupp Nitro 440 for a number of years. Fast and good handling sled for it's day.

😊 nice-looking Rupp. They were fast sleds and surprisingly reliable and consistent running too. Outside temperature conditions never affected the way they ran much which was quite unusual for a high performance sled of that era. i restored one in 2005 and rode it for several years in vintage derbies. I sold it to the Supertrax sled museum in Yorkton, SK about 6 yrs ago and now regret doing so. It does look beautiful sitting on a shelf on display. But i know that deep inside, that Xenoah 440 mill yearns to be fired up and ridden.

Had the Rupp Rally 440. Great memories. Love the engine sound 🐭👍

[@davidforsythe3037]

When I was a kid, my neighbor had one. Crazy loud. Real fast

[@DetroitMicroSound]

We had the 340, and 440, when I was a kid. Great sleds for their time.

I hand (2) brand new ones. 1972 Rupp Roug 295/ 25 H. P. and a brand New 1974 Nitro II 440/ 55 H.P. Loved Them Both they never broke down back like the old yellow dogs did. I raced many sleds free air you name it. The Nitro 440 was fast. My son later in life bought a good used 1975 Nitro II/ 44O that one to was bad ass/fast.

Where's the speedometer and windshield?

[@frankold2526]

Way ahead of all others of thier time Right off dealer floor these machines were insanely fast

[@mikeyd5969]

Those things were rippers back when they were new . Fast sleds for their day .

[@VonSpud]

I remember a girlfriend back when I was in my teens, her Dad had a couple of Rupp machines, one was the Nitro. I wanted one of those so bad back then... Couldn't afford it at the time of course Now in my later years I've ordered my first new sled due this September. BC XRS 850 154" x 2"

[@edwardcleveringa6842]

I had the same one!

[@SuperBigdanno]

Very nice!

[@dubiousf00d]

I have a period correct Rupp snow suit that would go great with this machine.

[@ianhotson6057]

You said in your video, that it's not perfect oh, well now sir you're wrong LOL it is perfect!!

[@funtyes1970]

very sweet sled i wish you open hood to see motor

[@Harpazoed]

My first sled was a Rupp American. A 400 about 25 to 30 Hp. After that All Cat’s.

[@RyanBenbow]

I had the American 650 hirth it was nice.

[@Harpazoed]

@@RyanBenbow I don’t remember a 650 American. Was it considered a Nitro or a Magnum? My 634 Puma had a Hirth in it also. I drag raced from 1976 to 81. I tell you what ( those were the days).

[@RyanBenbow]

@@Harpazoed that is cool. I have a garden tractor with two snowmobile engines. I use it for pulling. I have use Ear plugs

[@Harpazoed]

@@RyanBenbow lol 😂 wow. I bet you do. I had a 25 Hp JLO in my mini cycle (it’s a cross between a motorcycle and a minibike) that thing could go 80 mph in 1 second. I’m serious it was so quick. Great talking to someone who has been there too. ✋

[@RyanBenbow]

@@Harpazoed yup I sold all the triples I had. Winter ain't what it use to be in Michigan. And everything that went with Them.
