Cobra RMC-90 S



· Cobra standard bullet proof 6 speed bottom end with several ‘new for 2012’ shifting refinements common to the ‘yet to be released’ Cobra CX65 PV

· Direct – acting solenoid operated exhaust power valve integrated to the RM cylinder

o Reliable small solenoid used for years in the medical and farming industries is integrated into the PVL digital ignition system to open at a precise engine speed

o Opens quickly (30ms) for smooth power delivery under all conditions

o Handy inspection cover which allows one to easily confirm proper operation in the pits.

EVERYONE - Hurry - go out and buy the newest, latest, greatest part out there! I hate the "off season"! People come out with new products and we all run out and buy them before we know if they are superior in performance or really worth the expense.
I'm sure that if Paul is building this, it will perform, however, will it be SO much better that it's worth the expense?
What class will this engine be ran in?
Production? Hmmm, I challenge that NO Cobra is "production" legal........ People cannot go out and buy a COMPLETE Cobra so a Cobra is not a production machine that people can buy off the showroom floor. If I were to buy a Yamaha YZF450 chassis and put a Yamaha 250f engine into it, Do you think I could enter it in the Schoolboy Jr. class? Yamaha into a Yamaha........Cobra into Cobra......Same.....
Food for thought...

Engine builders spend a lot of time and money doing research and development so that they can provide the racers with the best possible machines to win races. This motor may be used in both 90 mod and 90 production. If you don't want to race against it then remember there is now a 90 stock class. I personally feel Wiley has something here that is going to help a lot of racers because this motor has the ability to be fine tuned to the riders style and is more forgiving if they happen to be in the wrong gear , KUDOS to Paul Marra!!!!!!;) ;)

It seems to me that a lot of time and effort from a lot of people went into building this powerplant.

We got to test a prototype a couple of years back and found it to be faster than our cr 85 mod and virtually bulletproof. ( i just couldnt afford it at the time, I know that Szymborski and Horton and Gennusa pretty much dominated with the first version. And it cant cost any more than what people pay to get a Two fast motor i wouldnt think?) I remember a few years ago i asked a top cvt builder what a motor would cost and he said " How fast you want it to go is directly linked to the amount of cash in your wallet".
I sold the cvt and bought a shifter.....And still spent the money afterall..... SPEED EQUALS DOLLARS, AND QUALITY SPEED COSTS EVEN MORE.

Kudos to the builders for putting their time and efforts into this project. ( im sure Cobra finally stepped up to help also).

I wish Cobra would put forth the support to the Quads that they give to the bikes. If they ever decide to do that it would ROCK OUR WORLD......

Nice job guys..... Cant wait til BAMA......

To be clear, with a little bit of welding and some machining this ECX90S is made by modifying the homologated ECX70 cases that have been in production since 2009. Each year since then the ECX70 cases have received improvements (crank bearing fit, shifting components, etc…) that the bike engine (CX65) received and this year is no different, although the shifting improvements huge.



ECX70 engines from 2005- early 2008 are not compatible with this 90 kit upgrade.



This kit is available from Wiley Mods exclusively using Cobra production parts, Suzuki parts, and a bunch of hard work.

Hey Paul, perhaps you can clarify a couple of questions regarding cobras. Does cobra only make 1 chassis for the different models ? Could someone order 10 cobras and get them right away or do you have to wait for them for months to be built.What is the reason cobra does not sell quads with engine installed ?

pmarra
12-01-2011, 05:39 PM
Don Cobra makes 1 frame for all models.if you order 10 cobers i will get them to you in 40 days. the goverment will not let them sel a quad with out head lights an brake lights.so to get around that they sel the quad with no engine in complete.

chunky0071
12-02-2011, 11:58 AM
It's not the light and brake lights that keep them from selling them. Trx90 and the Suzuki don't have lights and you can buy them.

pmarra
12-02-2011, 02:39 PM
Chunky0071 i appologize. I had to do some homework but heres the reason, cobras are not sold complete because you need a flag holder with a stop switch, roll over shut off switch, it can only run a maximum speed of 22 miles per hour, you need a nuetral start switch, a parking brake and also a few more things but i can remember, that is why cobras are sold complete.

Too much regulation !!!! Cobras are for race only sold by race shops only .Government should worry about more important things like the economy instead of safety crap on race quads that would have to be removed to race !! Cobra>the only quad made in USA and the government is going to bust there balls ! AMA should be thankful to have an American quad instead of all these Chinese yard quads.

In Reference to this whole "Production" rule, Don't be surprised if we start seeing JB's, Roberts, Lonestar, ect in the other production classes.
It's my understanding that due to the current state of the economy, the AMA has lowered its standards for the homogalization requirements. I've been told that the lowered the "availible" machines from 100 down to 25.....
IF this is true, a company like the ones mentioned above could easily show they have 25 availible.
Watch the Schoolboy class Dad's freak out on this one! OR when team CanAm gets smoked by a Lonestar Honda with the CRF450 powerplant. I know that if I owned Lonestar (as an example), I'd be putting together 25 ready for sale asap for all the classes....

Apparently you haven't raced much! Racing=money, and if you want to win at the national level you will need lots of it! I Thought by goin with a shifted mod, the expensive motors were over......guess not.

I hear ya Tim, but with that being said, I've got under $1600 in either one of my mod motors. One stroked to a 90 and the other is a modified 105.
With that being said, After watching one of these engines roll off the line at Muddy Creek, they ARE as good as advertised and IF your needing to stay in the production class - this is the only way a Cobra is going to keep up in the 90 Prodution class. The stock Cobra engine will have to be modified similar to Wiley's or the one the Collard boy (#180) is running - it took the holeshot - to run with the Honda 4stroke or the STROKED Honda/Apex CR90's (I guess they can run an RM if they so choose also!).
But IF your only going to run in the 90 modified type class, paying this kind of money is just crazy when you can build a regular dirtbike engine for much less that will run as strong as one of these. Just my opinion......

Well said, unfortunately no matter what class you race in atvs it is very expensive.

The guys that win consistantly have the high dollar stuff as not only does it perform but it usually holds up better.

Like my dad says IF YOU CANT STAND THE HEAT DONT GO INTO THE KITCHEN.

I do know that the amount of labor it takes to build that motor Paul is not getting rich. H

H [U] not true at all ive raced my blaster stock cyl 230,port polish, cr500 carb etc and use to beat the 275 cheaters and 240 bigbore kids all the time and my blaster was not a high dollar quad just saying 80% rider 20% quad. dont let your kids think its all about$$$

Im not trying to insult anyone but these top national riders have got their stuff dialed in.

im not saying its the only way but currently the top riders in the 90 production and girls classes are on top of their game and if you want to win consistantly it will cost you BIG BUCKS AND BIG TIME TESTING.

My son is a top national rider and i still am behind a few of these guys. ( i just cant get there..... its not for a lack of trying. these guys are just good and their riders are top notch also.)

thats why we do this , for the challenge........

This engine is production legal. After watching Maci roll with it, it is just as strong as the cr's or rm's or KTM's especially in the light Cobra chassis.

04-26-2012, 05:43 PM
The new rmc is expensive ,but not much more than a 2fast or R/T cvt. I do not think a stock dirt bike motor makes the HP of the RMC but a good rider may make it seem like they are equal,but a dyno will show the RMC makes more power.Most kids (like mine)do not use all the power,but when they are ready it will be there.

Right on Rocky!!!! Its getting out of hand. We get bashed at the local tracks for running a four stroke, and in a Pitster to boot. Then when Adam holeshots them or runs right with them and doesnt DNF they dont have much to say.
Adams 8 and has the shifting and manual clutch down pat. All three of his quads are manual clutches. He even pulls my Raptor in and out of the trailer.
When is it going to stop. Im content competing not winning every moto. Now maybe when he is 13 and is still running minis winning may be more important. But right now being 8 and running the 4 banger against mods and 2Fast quads we are happy competing.

I remember a few years ago, we all sat down at a cracker barrell after a local race and you were questioning me about running Nats. How much do you reckon youve spent since then? LOL

I wouldnt trade this time for anything. Even though it costs an arm and a leg, its worth every penny. Losey has it right, these memories are priceless. Heck, we have as much fun on the adventures to and from the track as we do at the track.

I do think that some people in the industry take advantage of us because they know we will spend (and can afford to) whatever it takes for little billy to beat little johnny. But thats how it goes....I reckon everybody has to make a dollar here and there.

Thats all you get in any youth sport, win a state championship and you get a plaque, a jacket or ring...We didnt do it for that back in school and I dont think there are many doing it for that reason here in our sport.

I do it for the time with the family, I do it to watch my boys hit the track with some of the fastest kids in the country, I do it because I like competition and it's a part of life in everything we do and I want them to experience that and see what it takes to be good at something, I do it for the memories-both mine and theirs, I do it for the videos, I do it so that I have something to talk about with my wife when they get to old to come and see us anymore....Mostly I do it because they love it.
