I just lifted a rear end of Rx-1, and it was heavier than any *rear end without snow in it I ever lifted. The front could not be dreamt of being lifted by the puny bumper, as it would disintegrate, so had to resort to grabbing suspension. It was as heavy as any sled I ever lifted. The color I saw was red, but I think the blue is sharper. Under the hood you could only see the tops of carbs, and barely see chain case oil dipstick. Your gonna have huge expense if you tag anything on the front end with one of these. *I hope the performance makes up for the congestive under hood area and weight. http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/nervous.gif

What is the dry weight on one of those ? I looked at the yami site and couldn't find anything about wieght. I bet it is still lighter than the tank I drive at 586 lbs. dry.

Uhmn, Sharkey, are you saying you dont like it?

sharky where did you see this. I thought onle limited racers had received theirs and I wouldn't think they would be racing a er model. Are you sure it was a production model?

I saw it at Sheehan's Yamaha in Watertown S. Dakota. I heard an ad on radio Saturday, saying come see the Yamaha RX-I, instead of RX-1. I knew the announcer had screwed up. So there it was parked a long ways in front of the dealers shop. It had been driven. Around 590 pounds with no gas, but antifreeze in it. It had a couple gallons in it when I lifted it. It would not be like a Doo for breaking in, as we ride 4 hours at around 200 miles to break in, and are restricted only a few percent on horsepower, you can't hardly feel the difference. On this Yamaha you run at 8000 rpm for 20 hours instead of 10200 rpm. It would not work for me. My first trip is high elevation deep snow riding. I would leave it home. 3/4 throttle and the weight would piss me off and get me plenty stuck.

ill stick up for sharky i saw one yesterday too at the columbia county fair at a dealers booth * it was red and yes it was heavy!! i like the looks though

The biggest pigs are.................
Yamaha RX-1 = unknown wieght
Ski Doo Legend Sport V-1000 = 562#
Arctic Cat 4 Stroke trail = 561#
Ski Doo Mach Z = 559#
Polaris XCR 800 = 555#
Acrtic Cat ZL 800 EFI esr = 547#
Polaris Frontier Classic = 541#

Fatest of *all sleds *= Acrtic Cat Bearcat 695# * http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/wow.gif *LOL
It has a 15 gallon tank and a range of 300plus miles with the 660 triple 4 Stroke.Just imagine 2 - 200# riders,a full tank of gas and oil,well,you do the math.

There you have it,I was bored *http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/wink.gif

I did not forget the T-cat. These are weights of 2003 models. If Cat still made a T-cat I&#39;m sure it would have been on the list.

Wonder what size track that is! http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/wow.gif LOL

I didnt find the back end on the RX-1 any heavier then my mach. *But the front is unbudgeable. *My guess for the sled is over 600lb.

mxz7, I know you listed 2003 models, but my in-laws 1000 pantera is listed I think at 570+ lbs and like 11&#39; long. *Man, I thought that was a tank, if that RX-1 is over that, I pitty the fool that has to dig it out. *I&#39;ve dug his out several times on uphill slopes *in 2-3&#39; of powder and man was it an ordeal. *The first thing you did was get undressed, because you had some work ahead of you. *The difference was at 174 hp, it would lift the ski&#39;s right off the ground. *The jury is still out on the RX-1

That DanR is one crazy dude.

No way man!! *That cannot be a real sled now can it???

What would you call it, a snowmobus?? *http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/wow.gif

If it is real, who made it?

The pic that DanR posted is Rocketmans sled. *http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/tounge.gif *He is like 7&#39;3" he needs all that leg room. *http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/nervous.gif

You forgot the T-cat.

that&#39;s the limo the Swedish Bikini Team used to ride!

I was referring to 2003 sleds. Yamaha will have to sign up for weights of sleds for grass drags. Just as the other brands will have to register. http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/wink.gif

I dont understand why yamaha is not relasing the weight and are putting a junk front bumper on it that cant even handle the weight. *

What the H3LL are they hiding. *And whats with the bumper. *I would be very suspisious. *Now there putting a 8000rpm revlimiter for the first 20hours. *What kind of engine takes 20hours to brake in. *Maybe 10 but more likly 5. *

Engines today especially motorcycle engines like the R1 are build in ways that reduce brake in. *They bore the cylinders with a plate on the top of the block simulating that the heads are on and toruqed so as there is a more exact piston fit. *New greases and bearings are around as well as syntetic oils. *

Say what you want but 20H breaking is also very suspisious. *My opinion and yes im gonna say it is that i dont belive that yamaha can get there bike engine to run under snowmobile conditions at 10500rpm like claimed. *In a bike they may do 10000 rpm for only a few secs but in a sled it might hold that for the whole lake or drag.

For all of you hoping for a longer living engine over 2 strokes. *Well good luck with a engine turing 10500rpm. *Yamaha is very weird over this one.

Skidoo with the Rev have not held anything back. *THey proved what it could do and showed us how the machine would look when we take delivery, *Arctic cat is simular with the firecat. *But yamaha wont even show you the real front bumber, Maybe its gonna be a boat fender. *I would be very learing of buying this one the first year. *

Any of you ever notice how easy it is to get ahold of bombardier. *They got contact us on there website, They got numbers to call, Customer reps like claire and carlos. *But when you try to complain or ask questions to yamaha its hard as h3ll to get a address or number and then they never return your call or email. *

Hope you know what your getting into. Oh wait you dont none of us do.

I hope this stirs the pot and gets some action going on this site. http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/biggrin.gif

They don&#39;t get stuck. *My stepdad has an old Alpine (70s?). *You cannot get that thing stuck, even with the bogey wheels and .25-inch lugs; it just floats too much with the two tracks. *Problem is it doesn&#39;t steer. *He used it up until a couple years ago to pull a groomer. *Now he bought a Bearcat WT to pull with.

Machzzz1, I know I&#39;m going off the posted topic, but I have to find out why people say the R1 motor won&#39;t work and it can&#39;t hold the RPM&#39;s. *I asked about using a sport bike motor a few years ago on this site and everyone said it couldn&#39;t be done, now they did it, and you still you can&#39;t believe it. *I have a Kawisaki ZX6R, 600 cc with a redline of 14,500 rpm. *I&#39;ve taken it on the highway and held it at 80 mph and 8000 rpm for 30 min. *It was a warm day, probably 85-90 deg F. *I don&#39;t know if the cold would have an effect or not. *As long as it can get oil then it should be o.k. *Now, I&#39;m a Cat man , but I think the RX1 is a good idea, but I still wouldn&#39;t trust it the first year, but I think it will work. *More than likely a few bugs to work out.

The only reason im sceptical is that a 4 stroke has many more moving parts then a 2 stroke. *All these parts must work at the exact time with presision or else the whole engine blows up. *In the winter time you have a engine that sees hot and 2 min later cold then hot again. *This cant be good for any engine. *

Sustaining a 10500 rpm during a lake run on a 4 stroke will be somthing to see. *IMO its to fast to spin a engine and it will only cause imediate problems or problems down the road.

I think it will work. *I watch AMA superbike and WSB races on the speed channel all the time. *WSB is 1000cc V-twin machines. *In AMA there is more of the Jap 1000cc four cylinder bikes and they never have any problems during a 26 lap race. *If there would be a problem it would occur their. *Those bikes don&#39;t get wussed around and the are probably on the edge performance wise.

At least the Rx-1 pistons are only 250cc not 400 a piece to spin at high rpm&#39;s.

There is no rev limiter on the RX1, bad rumour that I&#39;m sure *started on the cat forum. As far as the motor holding together at 10500 rpm that won&#39;t be a problem. May of todays race rocket street bikes scream alot higher than that with no problems. Come on guys were talking about a yamaha not a bombardier!!! LMAO

ya most crotch rockets rev up to like 13.5 to 15k before redline. I hope it starts good in the cold.

Hauler. Yamaha is probably japanesse for Atom bomb. *Go look at the rotax cart engines that spin up to 18000rpm and smoke yamahas year after year. *ROTAX knows RPM. *

Crotch rockets are much lighter and easier to turn. *Almost no work for the engine. *Put them in a sled where the oil and everything else is below zero. *Let the puishment begin.

Isn&#39;t there too many difference between a bike engine and a snowmobile engine to really have this discussion? *LIke, isn&#39;t the oil distribution drastically different because a bike engine always has net force on the oil toward the bottom of the engine (because you lean to turn) whereas a snowmobile will see more sloshing because the engine stays flat (unless you whoops it).
