Bryants' Moto-Skis


Updated 3/23/24






Since there is often misidentification and confusion about 1970 Cadets, I have written a guide which can be viewed HERE.

I have compiled a quick tutorial on the differences between 1971 and 1972 Capri 292/295/295-M sleds and it can be viewed HERE


I recently purchased a pile of Moto-Ski technical bulletins from 1970 to 1979 and have been working on getting them scanned and made available for everyone to view.  I will be posting a new one every few weeks and compiling them in the technical section as they add up over time.  There is some very interesting information and some real insight into the day to day operation as Moto-Ski worked to maintain a quality product.

Technical Bulletin 71-24 dated November 23, 1971.  '72 Driven clutch spring tension.





1972 Moto-Ski MS-18 400 (398ccm JLO)
This was my second moto-ski and has been with us for quite a few years now.  It is my favorite to trail ride because
rarely does it ever give any trouble and, believe it or not, it is one of the most maneuverable machines I have.  With just
the right throttle and weight shift you can get it to pivot at mid-track cutting tight corners but at the same time there
is not a hill or drift that will stop it.

1976 Moto-Ski Nuvik 340 (Type 343 Rotax)
I received it in trade for work on a trail bike and another snowmobile.  The engine runs great and the sliders are like new. 
The seat is in perfect condition but the original cowling had some close encounters with a solid object so it has been changed
to a nice '77 hood since this picture was taken (the '77 decals look similar). 

1973 Moto-Ski Capri 440 (436ccm BSE )
A special thanks to Dale Bechtel for adding this machine to our collection.  This is the cleanest and most original '73 Moto-Ski I have seen
and am thrilled to put it in the company of our others.  It has the factory optional backrest, original 2 piece cover and tool kit.  The 440 runs
great and the machines rides like new which is good since no matter how nice a sled is it should still be ridden.

1973 F440

1973 Moto-Ski F-440 (436ccm BSE)
This F-440 has the factory electric start option that works well.  Its a decent original machine that runs good
and retains its original seat and gas tank cover.

1972 Moto-Ski Grand Prix 340 (336ccm BSE SS)

I just finished a full bolt by bolt restoration of this sled and fired it up on the grass for the first time.  The 340SS BSE makes this
a surprisingly quick combination and the 94c comet clutch helps.  This is a bogie wheel suspension model with a drum brake
and fully enclosed steel chain case.  A special thanks to Steve Dahlberg for giving us the opportunity to add this rather rare moto-ski to our collection.

1971 Moto-Ski Grand Prix 634 (634ccm Hirth)
We did a complete restoration on this machine including a NOS hood but decided to keep the original windshield even with a few scratches.
What a handful on the snow! 

292 Capris

 1971 Moto-Ski Capri 292 #1 (L295 JLO) 
(Top left)
The early 292 Capris came through with L295 JLO engines instead of the more common 292 Hirth.  They featured
all black seats, black front bumpers (not chrome like the later ones), and '69 style running board mats.  Even though the 292
was moto-ski's full size economy model, this one has proved to be a spiteful machine with plenty of power for one rider.
Both machines were featured in the November 2011 Sno-Goer timeline article.

1971 Moto-Ski Capri 292 #2 (193R Hirth)
(Top right)

This is the model twin to the one pictured above but is the later version with the Hirth engine and chrome bumper.  
It still has its original air box, rubber gas tank strap (hard to find not brittle and broken), and factory plastic warranty
information card.  It has had the seat recovered to the original all black (yes the 292's had black seats not black and
orange like the more expensive models).  There was enough of the original cover left to pull the staples,
 cut the seams, and lay out for an exact copy on new material.

1971 Moto-Ski Capri 493 (220R Hirth)

Well here is the progress so far on the '71 Capri 493 project. This is a sweet running little machine with a great rumble and lots of torque. 
Paired to 14/30 gearing it will really cruise. The plan is still to make up some "Capri 493" decals and recover the seat to a more factory style.










   1971 Moto-Ski Grand Prix 338 (440T BSE)  
I have had this 338 Grand Prix for quite a few years and ran the factory JLO quite a bit but decided to upgrade power to a 440T BSE
with twin HR Tillotsons that I built up.  It runs super and recently completed a 22 mile vintage ride flawlessly.  I am still running the
rather low 12/30 factory gearing which hurts top end but allows the engine rpms to stay up on tight trails and makes it a blast to ride.

Mini Sno

Moto-Ski Mini Snos
(#1 1970 223ccm JLO top)(#2 1971 223ccm JLO left)(#3 1971 338ccm Hirth right)


The acquisition of this '70 mini-sno to our collection completes all three year/engine combinations made.
It differs from '71 in quite a few ways but most notably the entire belly pan is fiberglass and uses an aluminum
bumper.  It has a peg clutch like the '68 and back machines and an engine guard that is all white instead of black.
This little machine has a good running engine and is a solid start to a restoration.

We purchased this sled from the son of the original owners only about 15 miles from where it was purchased new.
The funny part is that my father test drove this exact one back in 1971 at the local dealership before it was bought
and remembers when the buyers came and picked it up. The little sled has been stored indoors for most of its life
and so has been preserved fairly well. Even though it was marketed as a children's sled don't be fooled.
My first ride on it revealed that mini-snos are super tippy buggers and the 10hp is more than enough power
to lift the skis off the ground (right over backwards if you were sitting wrong) and carry them a long ways.

We recently found this original R-code 338 mini-sno complete minus the seat.  I cant wait to restore this sled
and get it on the snow to see just how crazy 28hp can be on a chassis that can barely handle 10hp. 


6 - 1970 Moto-Skis

#1 (pictured above)
This one is a Zephyr with a 375 JLO single.  I consider it to be a real time capsule that was
spared much of the abuse and neglect that so many sleds were subjected to.  It has a low serial number
for the model (C5J-70-17 ) and features some interesting early 1970 characteristics like a '69
body (subtle differences from '70), a '69 backrest compartment and tail light, and a '69 dash.  Also
note that the sides of the headlights were never drilled for engine size badges.  It is
a nice original sled that goes well with our other ones.  A special thanks to the AnteDomenico
family for giving us the opportunity to have it in our collection, it will always have a good home.

#2 (above left)
The second is a 338 Hirth Zephyr that was restored by my father in law to its current nice condition.  We have run it
on every vintage ride we have been on in the past five years and it has never let us down.
#3 (above right)
The third is a MS-18 with a 500 Hirth.  The cosmetics are quite good and even better since it now has an original
pattern blue and white seat. Luckily the two front and two rear track sprockets are in great condition
(rare for a '68-'70 MS-18). I got to enter it in a radar run at the Naples, Maine, Winterfest 2010 and reached 47 mph in 1/8
mile.  Not bad for such a big machine.  Behind in the photo is our '70 ski-mo cutter purchased new with a '70 MS-18.
#4 (not pictured)
Next is an MS-18 that had a 372 JLO electric start when we got it but the engine turned out to have fatal
internal issues.  I considered taking the time to rebuild another 372 I have access to but decided not to after looking
at a newly rebuilt 634 Hirth we had sitting in the corner waiting to go on something.  So long story short the machine is
now a 634 MS-18 with electric start (its so nice not to have to crank it over).  We have had the opportunity to drive it
around quite a bit and were and still are impressed at how smooth and powerful the combination is.
#5 (below)
This 317 Hirth Zephyr was restored with the intention of making it a nice rider.  The 192R 317 is a great motor with
lots of power for a single yet very reliable.  I hope to put some miles on this one this winter.

#6 (below)
Of all of our moto-skis, this is the most original and perhaps the nicest one of the bunch.  Last registered in 1973
it only has 406 miles and sat under its original cover in heated storage for most of its years.  This Grand Prix has the
SA340SS Sachs engine option which is the only non racing Moto-Ski to offer Sachs power.  A special thanks to the Clarks
first of all for taking such good care of it over the years and second for the chance to add it to our collection.

1969 Moto-Ski Zephyr 500
(493ccm Hirth)
While this sled started its life out as a 300 single, it now has a 500 twin to liven it up plus a deluxe dash to give it a
more model correct look.  Before you write this off as an imaginative custom job, however, I am not convinced that Moto-Ski
did not make a 500 Zephyr in 1969.  The biggest reason for this is that I have seen photos and decoded the numbers
of an original 1969 500 Capri plus heard from a few dealers back in the day that they did in fact sell a very limited
number of them.  From there it is not a very far stretch to assume that if a 500 Capri was made then a Zephyr would
 not be far behind.  Anyone out there have, had, or know of an original 500 Zephyr?  The model number would be "34".
I would love to hear from anyone with any input on the subject.

1969 Moto-Ski Capri 760 JLO
I knew squeezing a giant 760 JLO fan motor onto a small 300 Capri chassis would be a challenge but that was something of an understatement.  The
entire driven clutch and supports had to be offset to the left like the large engine '69-'70 super modified machines.  I was lucky enough to have an
extended front shaft and aluminum bearing block from a 634 Grand Prix to match the offset and get the elephant engine to set centered on the tunnel.

Heavy duty bogie springs, 2 extra leaf springs in each ski, and arched ski extenders set the suspension up to handle the extra weight and power.  The
motor breathes through a combination of dual HD carbs and twin megaphones that sound great in an open field and are plain lethal in a closed garage.
This sled is a handful during regular operation and a white knuckle joy at full throttle.  The next steps are a short windshield and a blue and white seat
 in the style of the '69 super modifides.


1968 Moto-Ski Zephyrs  
(297ccm JLO top, 300ccm Hirth bottom)
I see no clear winner between the JLO and Hirth as both are good reliable power.  The tow behind is a 1970
Aurele Marois 'Alouet' sold by many Moto-Ski dealers. 

1965 Moto-Ski Model 200
 (300ccm Hirth)

We recently added this 1965 Model 200 to our collection.  It is a very solid machine with a clean gas tank and a nice running 300 Hirth
The original track is still there with no broken steel cleats but I did put on two 1968 skis as it only had one correct '65 ski when I got it.


1965 Moto-Ski Model 100
 (247ccm JLO)
We totally stripped, sandblasted, primed and painted this machine for my uncle in the summer of 2001 (The paint
on the cowling is original).  It was a lot of work but as you can see it was well worth the time.  This picture were taken at
the first annual 1 Lunger 100 held in Turner, Maine.  Since then he has acquired a Moto-Ski for every year from 1965-1972 and
plans to restore 1 a year.  His sleds include '65-'67 Capris, a '68 Zephyr 300, '68 MS-18 297, '69 MS-18 300, '69 MS-18 500,
'70 MS-18 500, '70 MS-18 634, '70 375 Capri, '71 634 Grand Prix, '71 399 Capri, '71 Mini-Sno 223 and a '72 292 Capri.

others that started snowmobiling for this family in late 1969 .



    1973 Suzuki XR-440  
(432ccm Suzuki Twin)

My father bought this Suzuki brand new and has run it very minimal considering it is only on its second set of
spark plugs.  Since it has never set outside other than to run it, it is in great shape.  The only thing it needed was a
rear sprocket which it got (replaced front and rear).  This was a top of the line 85mph+
machine when new, not to shabby for a stock snowmobile in 1973


Skee Horse
    1968 Johnson Skee-Horse Wide-Trac 20    

(362cc OMC opposed twin)
This machine was used for a short time hauling a sled to carry wood and then placed up into a dry barn until we
brought it home.  It came to us with the owners manual and dealer brochure given out when the sled was new and still has
the original OMC drive belt under the seat as a spare.   The opposed twin runs great, the reverse is a blast, and a
new windshield makes it look pretty decent for an original sled.
