Mcoy motor shop is building a 599cc Saber tooth CR 500 motor

[Slow old Fart]

You can look him up at planet sand, he was mating a 599cc or a 580cc stroker CR 500 bottom end to a Sabertooth 500 top end using a 50mm Lectron carb.

Somedody may want to call and see how it turned out. He was shooting for 100hp ON GAS.

If it works out he will be taking orders.

why go to the trouble when the saber bolts right up to a trx250 bottom end and you have 6 gears. when they make a bolt-on after market cylinder for the cr5, then ill put in my order

[AlisoBob]

N20 is cheaper.

[100hp honda]

ya N2O is cheaper. its too bad the guy that makes all the high perforformance after market 2stroke cylinders wont make one for a cr5, i guess the demand just isnt there. but if he ever decided to, he has the machines and knowledge to make a far superior cylinder design to the OEM.

[bigjay]

so they make a big badass cylinder for trx's but not cr500's? theres more 500 guys than trx guys isnt there? you dont see trx's at the hill climbs but you see a lot of cr500's.

The TRX has a weaker bottom end and is heavier + a CR 5 does not need a complete new crank assembly.

theres a million more cr5 out there. BUT only a couple of those cr5 riders would want a badass cylinder, most dudes are trail/weekend riders, they cry about the too much compression and too much power as it is. the dude that makes the saber cylinder could easily make a 600cc cylinder for the cr5 with a totally new and far superior port layout, but i said it already, there is no demand. how many dudes from this site would be interested in aftermarket cylinder that makes a ton of power more than a stock cylinder?? about 6 guys from this site, and about 3 guys from the other site....get my point? its a major process to design and market a cylinder. theres some pics of the process to make these cylinders on that sand site- it takes computers, cnc machines, molds, machines to heat the aluminum to boiling temperatures.

[ISBB]

would i want it hell ya... Would i be capable of using it to its full potential.. Probably not... Would i shit myself everytime i grab a handfull.. YUP!!! Gonna have to bring more than a spare set of drawers to the dunes

[sabreguy]

HELL YA it would be cool to have a CR600!!!!!!

It would be a blast in the Dunes!!!

[100hp honda]

the guy that designs, manufactures, and sells the saber, cheetah, sphinx, cub and DM cylinders, his name is calvin. i dont know him personaly but im a member on the website he is on. i could ask him how much demand it would take to have a cr5 cylinder made. he will most likely laugh at me but ill ask and see what his response will be

The TRX has a weaker bottom end and is heavier

yep and it is also putting way more load on it by driving those big dual tires, so if it will last any amout of time in the TRX it should have no issue in the 500 frame. Also to get a exrta gear I'd be happy to pay the weight penalty.

[100hp honda]

i had a dream once. unfortunatly it would take more money than i have right now. a saber motor in a aluminum frame gen2 or 3 or 4 would be the ultimate sand bike, not sure how it would do as a hillclimber though. this is a motor/chassis combo i thought of quit a while back and im sure nobody has ever done it. a good fabricator could make it all fit like a glove. theres several guys runing methanol sabers in 4wheeler chassis on the sand site and they havent mentioned any motor strength issues. the saber is quit impressive if you ask me at 100+ hp. im not endorsing this company but if i had the cash i would be on gen3 or 4 with a saber power plant. check it out yo http://saberracing.com/

That is what I am trying to build. I am not real happy with Kalvin. He told me they were going to be doing a run for CR 500's around 2 years ago,well guess what I bought a chasses especially for doing a steet legal 100 HP motard and I bouhgt the wheels carb tank and was having a pipe built and he never made it. I mean like I should have just finished a regular cr5 with a CRF 450 chasses but I wanted to build it one time with a Saber and not have to go back and make hack chages trying to get a saber cylinder to fit afterwards. I will see what Mcoy does but a 100 HP Cr5 is probably going to be around 3 grand + in mods.

You are going to have to cryo treat the whole motor under cut all the gears and buy a lock up clutch but a street legal gen 3 450 that is a 100HP is priceless!

[Slow old Fart]

N20 is cheaper.

Bob a street legal 100HP motard would be deadly and leave all the sport bikers crying in their beer!

It would shread anything on the road in performance for back street racing!!! AND I MEAN BAD.. The bike would be a legand of moto head folk lore.

+ counter balancer too.

I was looking ay TRx bottom ends and I wonder if there is any way to put CR 5 gears in it. Calvin was gointg to do a set up to where you just bolted a CR bottom to it and went with the stock crank. The TRX needs a new crank.

That is why I wanted someone else to build it so I would not have to be a Guinea pig. i was going to do it my self but I do not have the balls!

i think you lost your marbles brotha. saber is drag race only. trying to make it work in a chassis for street use is just silly.

No it is not I have talked to Neal who did the testing and Kalvin who builds the cylinders about it, just go look at the dyno curve it is broad as hell.

Kalvin said it indeed would be a mr maggo ride and deadly quick. he said it would hurt you quick and it was not the delivery but how much of it there is in a 230 pound motard.


The bike with a 150 pound rider should click of 9's with no problem running no nitrous.

The bike would be as close in alot of ways to the old milliom $ 500 cc GP 4 cylider 2 smokers in performance form 0 tyo 100 MPH.

the bike would smoke anything for around town block steet racing. it would even smoke the cost no object GP bikes for that apt.

The machine would be deadly but with a 300 pound sow on board a kid on a kick n go would probably come buzzing past me.

i would of had it built a long time ago but Kalvin never made the cylinder. If enough people ask for one he may do it but Mcok is taking it to another level but what about vibration is my ? that is why i was not willing to experiment with over 3 grand on it.

I want somebody else to work it out before I buy.


I got tired of waiting so I just bought a road riper 150 RWHP street bike mad max special and I can already see a saber motard would be just to much fun!!!!!!!!!!

[100hp honda]

better talk to some owners of the saber first. people have lied to you if they said it would be well suited for street use. 6k-8k rpm it goes from 60hp to 100hp....you call that a flat power curve?????? that kind of power would hit you like a fuggin sledge hammer

[bigjay]

6k-8k rpm it goes from 60hp to 100hp....you call that a flat power curve?????? that kind of power would hit you like a fuggin sledge hammer

that bastard would toss all 340lbs of me around like a rag doll, all in a matter of a half of a second. i didnt realize these were drag specific combos, i see where the demand from current 500 owners wouldnt be high. Your right, alot of guys tone their 500's down as it is ( fly wheel weights, sprockets etc) trying to get rid of the hit and keep the power maneagable, if the power made from one of these badass cylinder combos was "steetable" meaning useable on the dunes or track or just for all around riding, i think the demand would likley be higher .. hell i wouldnt mind having 30% more power on tap, then the 140lb guys on 250's wouldnt be able to hang with me or ide be able to run with smaller guys on stock-ish 500's.

The CR 500 is the same way, 2 smokes are like that that is why alot of us like them. It can be done just gear it down. The biggest problem I see is how much power will you loose with the carb kicked to the side?

I am talking about for a street application,you put a big tire on back and gear it tall and it will slow it down. look the pro's were running 200 HP 4 cylinder 2 smokes with no problem. no it is not for off road riding. I would never attempt to use that for a dirt bike unless it was drags and hill shooting.

The guy who built one that was 175 HP turboed on the dyno told me it was manageable if you new how to ride ( which I don't ). He lead me to believe if you new what you were doing it would be about the hottest thing on the street.

I don't know if you have ridden a supermoto 500 but let me tell you my 2000 with a 87 warmed over is all you want. Any one can ride a megga powered bike down a 1/4 mile stripe but the minute you put paved corners into the mix it is a whole differant story. they are very hard to dial through a corner. unless you are a Kevin Shwantz and can light the wheel up and go sideway no matter what the corner is, they just ain't that great, so to think that a 100 plus HP supermoto is going to be a realistic ride just ain't gonna happen. you would be so slow dealing with enterance and exit that you would look like a joke. A 100 hp supermoto would be just like the guy's with Nos/turbo'ed 400 plus HP Busa's. Monsters in a straight line, useless for anything else.

You are right and you are wrong, I said I may have problems getting it to work because I do not know what I am doing. But the bike will work fine, like I said the GP bikes made this look like a toy.

I have street legal CR 5's already and I find them too be a joke. REAL SLOWWWWWWWWW! My 1200 cc street bike which is a mid 9sec bike is no problem to ride fast and push. I can just imagine how almost that kind of excelleration in a chasses 1/2 that size n weight is going to rip.

You are probably a small guy saying a CR 500 is alot,you tie 330 + pounds to one and you are trying to figure out when it is going to go.

Do you use a steelie or a Aluma Tub? a alumatub is designed for high speed street use to start with with proper set up. An aluma tub for this is great and should be no problem but a steelie would have serious limitations like what you are talking about. In high speed corners a steelie would be trying to tie itself in nots not enough support up front.

[ou812]

Mine is steel with a 16.5 front and I can kick butt on the 2 local AF 500's because unlike a roadrace bike, a SM needs a certian amount of give (flex) The AF's are less forgiving, that why most stay with spokes not mags. Second almost all SM riding is done at low corner speeds 5 to 50 mph. I think if you got out on a track set up for SM you will find power ain't the issue, even if you are blinding fast the pack will kill you on most of the course. like any road racing the key is drive and this is were the 500 is very weak, 450's are on the gas at the apex with the peg on the ground, even with a bone stock 500 trying to drive at the apex will spit you off faster then you can say "Oh Shit". What your talking about would only make that condition worse.

Also the 500 has no engine braking ,again this puts you in a worse position the a 4 banger which can set up for the corner in a vastly better fashion by what is known to most as "backing it in".

On the topic of 500 GP bikes that does not trans late to a SM 500 single. GP 500 bikes were multi cylinders with a way wider spread of power and vastly better ability to tune for each track it ran on, also in the modern era GP 500's were changed to "Big Bang" engines at a cost to HP but while having less HP they picked up better drive which in turn produced faster lap time. The lesson leanered better drive is faster then big HP numbers. Lastly the skill need to make a 500 GP bike go fast was incerdible, it took almost super human skill to ride one at a competitive lap time. Case in point, The best 2 or 3 riders that wrote for mags Mat Oxaly and others and tested true GP bikes were faster on lap times on 250's then they were on the 500's they would test at the end of each season.

But what you appear to want is fine as a great shits and gigles bike.
