I've been saving up the empties and picking up pennies where I can for the last couple of seasons in the hopes of one day buying a turbo'd 4 stroke. All of the guys I ride with think I'm nuts, but I started riding sleds in order to access ski terrain and kite-skiing terrain, so I looked at the sport from a different perspective. And above all else I hate burning oil. But now I love sledding for sledding, and the skis get left behind more then they are taken. Who the hell cares what we are on, as long as we are sledding. Snowboarders and skiers get along, hell we even learn from each other... kitesurfers and windsurfers do as well, now if only the 4 stroke guys and 2 stroke guys could too.
Last month we were out in some very deep, very light pow, with 3 XP's and a couple of 07 Doo's, with me on my lowly 03 RMK 700. The Doo's were all trying to highmark each other, riding in each other's lines and getting 10 maybe 20 feet higher each time, cheering and high-5ing after each higher mark. The whole time this old fat dude was sitting on this old RX-1, quiet as hell. After everyone gave up, saying that we weren't going to get higher. He actually asked if he could give it a shot. We said yes, off he goes, slowly, goggles still around his neck, half way up the first incline, he even slowed to allow a guy who was side hilling to pass above him, then off he goes, in his own line, through untouched pow the whole way... he blew by the highest mark by 500+', and he turned back when he wanted, not when he had to... it turns out it was his first sled, and he bought the whole setup, RX1+Alpine turbo for under $6000 plus the labour to build it.
Now all the guys want one, and we sat down and figured out the cost of building a Nytro and operating one, for a 2000 mile season... used Nytro (hey it's just getting broken in at 500miles) $8000 (from the US), track, rear suspension, tunnel, shocks, seat, light weight goodies, we'll drop close to 100 pounds and it'll cost about $6500, now we are up to $14500, with goodies, and we are right at the wet weight of an XP (wet weight to wet weight) the Nytro is far more reliable then the XP (on average, of course on a case by case basis it might differ). Annual operating costs for 2000 miles = $600 in gas, $50 oil change, $65 belt (just to be safe) $250 annual tune up... totals $865.
For an XP, I wouldnt touch a used one, cuz I want the warranty. So now we are talking new... the price is right around $12000 right now, out the door (in Canada. It might even be more, but I'm trying to be generous). Pipe, vent kits, clutch kit, re-gear, that is another $1,500+, So lets say the whole setup was $13,500. Annual operating costs for 2000 miles = $750 in gas, $250 in oil, belts are being replaced for free under warranty, for now, but lets say 3 belts, so that's $300, $250 annual tune up... totals $1550. This of course assumes that nothing else breaks, which so far, out of any of the XP's we ride with, this has not been the case... and most items have been non-warranty items. So the operating cost is more then 80% higher then the Nytro.
So after year one, the Nytro's total cost has been about $300 higher then the XP. This includes purchase, mods and operating costs.
After 2000miles, most of the guys here are getting rid of the Ski Doos, and trading in on something newer. They have been consistently losing about $4000 over the purchase price of the sled, this doesnt even include the mods. Now if we assume that due to the reliability of the Nytro, we'll keep it for three seasons, then if we were to repeat everything above, the Nytro's total cost over three seasons, including purchase, and still having the sled at the end, is just over $17,000. The 2 smoke owner would be sitting at over $30000 for the same 3 year period. That is almost double the cost in a three year period.
I'm not trying to pick on the XP's, I think these numbers are pretty representative of all 2 strokes.
This obviously doesnt include major engine mods.... if we were to include those, say a $7500 turbo on the Nytro, running at between 12 to 15psi so it is still very reliable, and $4000 of additional work to the 2 Stroke Engine, probably wont help it in the reliability department. Even then if we kept the Nytro for 3 years, and the 2 Stroke for 2 years, then the Nytro's total 3 year ownership cost has increased to $24000 and the 2 Strokes would stay about the same (as the costs of the depreciation is replaced by the cost of the mods...though technically the depreciation would increase in year 2, since it is now a 4000 mile stroke sled). Now there is no comparison in performance, and it is still cheaper to run.
Sorry if this kinda rambled, but anyway I've run the numbers, if you look at the total cost of ownership, I just haven't been able to find a way that the 2 stroke more economical then the 4, in the long run.
I've also had way too much time to figure this stuff out, since I've had too much down time, waiting for replacement parts for my 2 smoke.
Have Fun
