Got the 650 Ninja engine kit here.

it is longer,,taller,,,wider by a bit more than I had hoped.

If put in the same position as the 450 it would sit way too tall.

doing some design / engineering on this. Not 100% sure if I will put it in this chassis,,,,,,looking at some different ideas on this,,,we will see

Here are a few pics of the installation I did on the Raptor when I built it. Maybe it will give you an idea or two. One thing I did is flip the throttle body around so I could route the intake to the original airbox on the atv. The gas tank is a custom aluminum tank made to accept the stock fuel pump.

nice job on the install. Looks clean and like it was meant to be.

all the limiting factors are different from a quad install vs this chassis though.
I can fit it in but there are compromises I do not like


to make it work, I may need custom headers, custom airbox, and design and build a custom oil pan, maybe a dry sump system.
It's just to tall as is

all adds to the cost which then pushes it out of the budget box I am trying to stay in.

Best way for this motor would be back to our engine cradle dual A arm design to get the bigger motor low.
This adds weight & cost back in

If I do that,,,,,,I come full circle and might as well put a 600cc 103hp engine in it. Those are less $$ than the ninja motor and more power.

still working on some things for this motor though

I realize the 450 with built in reverse is the perfect fit for this buggy and rear suspension design

Thanks for the comments on the Ninja install. It was an interesting balancing act to say the least.

I understand the challenges you have on your hands. The footprint is an issue as well as well as keeping reverse. I am hoping there is a way to make a buggy the size of the 450, but with more power. The Oregon dunes out here have a lot of trails and fun places to ride, but if the buggy is too big, you miss out on some fun spots. I have seen a few small buggies, but they are well underpowered and don't have the fun factor. I will give it some thought, check your previous pictures of the 450 and see if an idea comes to mind. Blueridge performance may have some of the parts you would need, allbeit more $$.

Hey Protodie,

Not that I have as clear a picture on the challenges of the 650 install, but looking at the pictures of the 450 installed (p. 21 of this thread), it looks like you could move the cross beam frame piece (just above the air inlet) to the rear a bit and allow for the top of the engine to stick up between the rear of the seat and the cross beam. Ofcourse, I am many miles away so I could be way off on this. I don't know how much that impacts the CG of the engine by raising it up so that the bottom clears the rest of the chassis....or for that fact mates up with an FNR transmission...........

The header pipe that comes with the Ninja can be cut and rewelded, allowing reuse of the pipes and collector, that's how I got away from using a custom pipe for the ATV.

cross bar is a for sure change and we did not even install that ,,,knowing it would need to change
oil pan is as low,,,or lower than the exhaust, so both would have to be done to drop the motor.

with no changes the engine would stick up above the back hoops by 10-12"

no good.

I will continue on with it, but need to put it aside for a week or so & wrap up some other projects

Hey Protodie, any updates on the buggy? How are things coming along?

ProtoDie
06-05-2012, 03:45 PM
decided to put R&D hold for the 650 engine right now.
Putting a 450R in for customer order.

Motor & engine stand are in my office , but may be a month before I can get back to that one.

Did some final changes tweaking and testing on the 3 point rear over the past few weeks.

so not much to tell for now.
few weeks I should probably have some new stuff on this

I decided to not put the 650 engine in this chassis for now.
The 450 with reverse built in is just a perfect fit and great power

The 650 will fit and can be done and will be a good power plant but I feel the size, power , and cost will push it out of the price range goals.
it is just too close to our 600cc buggies we already offer

Plus, at 70hp, size and weight,,, I feel you almost might as well put a 600cc engine (100hp)in,,,,,which would bring me full circle to our 600cc buggies anyways.

If any one is interested, I have a nice 2008 Ninja 650 motor kit and reverse unit available


The next design / build will be the next generation -new & improved version of our MXT buggy
Maybe 4 weeks before we get to this though

50" Wide
95" Long
65" Wheel Base
400lbs Weight (approx.)
.083 x 1" Dia. Tubing
Coil over Shocks
Approx. 12" Travel
350-400 motor with reverse (quad engine)
5 pt. Racing Harness
dual A arm front
3 point straight axle rear, just like the XK450 buggy

Are you planning to use the KFX450 motor in this or something different? Seems like that powerplant worked well for you in the other rig and had a reasonable footprint.

ProtoDie
06-13-2012, 12:33 PM
2 seater, eventually... same suspension and mechanics on a different frame.
It is all designed up.

I have a customer who is interested and if they want to go froward, then we will build it.

The KFX450 motor would be great in this next one too.

We put a air cooled Yamaha warrior 350 in one (MXT) and that flys.
lap times smoke our MXT a built 13hp engine

the 350's and 400's are cheaper than the KFX450r and have reverse so there are many to choose from.
They have been making the warrior 350 for 20 years

May go with one of those because there are more available....we will see

by this fall will have 9 MXT buggies racing together and probably by next year all converted to 350-400 engines.

2 will be my kids and 1 for me to race with them.:D
going to be some good racing[smilie=mhihi.gif]

this is our same single A arm and 3 point swing arm MXT
with 6" of travel

6' tall adults fit in this , no problem

geared for 65 mph top speed

Sweet! Any cooling issues or special mods needed to get the air cooled warrior motor to work like that? Those 350 motor should be a great price..:)

ProtoDie
06-13-2012, 06:40 PM
no crazy mods.

so far no cooling issues. testing has been pretty much pinned to the floor on our track for 15 minute intervals with out issue.

he did add an electric fan in front of the motor, since it is blocked from natural air flow

Looks cool Protodie. If your new design is running at 400lbs, that is close to the typical ATV weight and it should perform ok in the dunes. How much difference in cost if the KFX 450 vs a 400 engine? I remember years ago when I had a 350 warrior ATV, it was underpowered for the dunes and had a transmission problem. Under load up a dune, it would pop out of second gear and go straight into neutral. Not a good thing when you are working up a 200 ft sand dune. The dealer could never fix it, ended up trading it in. I am sure it has been fixed, but it left a bad taste with me.

ProtoDie
06-14-2012, 01:59 PM
KFX450 price is about double of the 350

400's are abit closer,,,,,,I am leaning towards the 400's

350 is a bigger , heavier motor.....so if there is room for that, then the 400-450s will easily fit.

it will be abit before I get to this. Customers 1st,,then the next design/ build

That kfx motor moves really well. Just curious, do you sell the motors by themselves or do you have a source you are willing to share? I was out this weekend at the dunes riding my TRX450 and my wife has an LTR450..such great motors but the kfx is the onky 450 with reverse and you don't see much of them around here short of a like new complete quad now and then. I can source a used Raptor motor with reverse much easier but I like the power in the 450 motors better.

I have a sneaking suspicion I will be looking for motor upgrade options on my build this winter and I like to keep it compact with reverse and four stroke and light weight. Not many options fitting those goals.

Also any thoughts on a raptor 700 motor vs these 450s? I have ridden a couple of stock to slightly modified carbed 660s, but never was as impressed as I am with the 450s.

ProtoDie
07-30-2012, 04:03 PM
nope, I sometimes buy the whole quad or bike and part them out after I get what I need.
no special sources right now

I like the raptor, but it is quite a bit heavier and I think it may take up a bit more space.
Other than that I think it would be a great motor.

you are right & the KFX 450s are a touch harder to come by.

Also,,,,,,The polaris outlaw has a 450 with reverse and the engine is KTM


you could always go 400 as there are tons of them. Then maybe put a big bore kit on it and get similar power as the 450,,,,,,yet light weight and reverse

Azeriksis
07-30-2012, 05:56 PM
Another good moter is the outlaw 525. Its a ktm engine with very good torqe also has built in reverse. Another option is the trx700xx im not sure if it has built in reverse but it is a more compact design then the raptor 660 or 700 and a lot of power to boot.

Do you have the room to fit a 700xx in the next version of the MXT buggy? Based on the specs below, it would have a good power to weight ratio.

Predator had a 500 but no reverse in the early years of production. Can't remember when it got it though. Anyhoo, the 500 is like a bigger 400 or smaller 660. Just not the SNAP of the 450's.
But something to consider, not a bad motor.

I have ridden the 525 as well, its not bad, but its not something to get excited about. One of the ATV's we have is the Z400 and it does pretty good on the dunes for a sport vehicle and it has reverse.

Very nice looking, although I am having a hard time locating the supercharger[smilie=shocked.gif]

On another note regarding the 450XK, can you compare it to an ATV or DXT1000 setups in terms of stability through rough terrain? In other words, what do you notice that is different between the three given your riding experience? Have you had a chance to test the 450XK through a set of whoops in the sand or dirt, or maybe something that the 4x4 jeeps and such dig up in the trails? The reason I ask is that an ATV swingarm setup will beat the crap out of you on whoop trails, even worse when the holes are offset and one side of the quad find the hole, then the other. Heck, the only ATV I have that eats it up is the old 250R Honda....

Drain,,the plastic ones would hold up to the forklift.
so I added these to the brake rotor laser order :D

ride is excellent. ATVs have 7" of travel?

this has 17" front and 15" rear with 6" articulation in the rear straight axle.

the articulating axle smooths out some of the rough un-even terrain. testing was on a couple of different tracks, jumps,,and trails.

more pics next week,,,, time for electrical, radiator, linkages and cables.
alot of work not really worth pics

Are those the 7 1/2 rotors. And do you have a pic of the wheels from above while mounter on the spindles (or from the front) I guess I want to know how far the wheel sits from the base of the spindle.
The spindle by it self looks wide (awesome though ) just wanted to know how close the wheel is to the brake rotor (and it's because the dust cap is longer I guess. That's what make it look longer)


I love this car and wish I could buy one

in the last pic you can see,,,,what I think your asking?
they are packed right in to a 10" wheel

front wheel kits are the same we run on our bigger buggies.

actually the lower front A arm is the same as our SS1000 2 seat buggies.

12" wheels you could run bigger offsets on the front

got it back from Extreme Graffix, the place I get all my stickers done at.

also got the fuel cell and air box & filters in

Front tires look borderline small and measure 19",,,,supposed to be 20"
rears are supposed to be 20" and are 21"

so we will put some 22" on the front ,,,,,figuring they may be 21"

yup,,,,,,,,,,,,,,,,,you guys will fit :-)

only one at a time though:eek:

I decided to stretch the interior 2" longer.
I am 6' 200ish and fit in the 1st prototype, but thought the extra 2" makes it really a good fit for adults too

Glad you like the air set up. Easy to check and change filters if needed and can run many different common filters and sizes

Yes, we have been running the other car (1st prototype)and testing for a few months now.
motor is perfect for this.

trophy carts run 450's and I think they weigh more,,,,especially when the plastic bodies are packed with mud


I did switch the aluminum axle to steel.
center sprocket keyway was starting to give a little.
so this will be a touch heavier between that and some of the .120 wall tubing requested by the customer.

also upgraded from the quad Radiator to a civic radiator fan and shroud like our bugger ones.

I will scale it out later this week

Hey Protodie,

I did some checking around on various ATV engines while I was at the dunes this week. From what I hear, the Raptor 700 (not that it fits) is not a good for acceleration (it does not wind up quick. The KTM 525 engine that is in Polaris ATV's works well and has reverse, but if it breaks, watch out it will nail your wallet hard.

Given that, I was thinking that if you had the room, you could install one of those inline reverser units in place of the jack shaft setup. I know it adds to the price, but if one wanted to use a different engine that did not have reverse in it, this might solve that issue.

By the way, what is the seat height above ground for this sandrail? I am curious to know if the rider CG is lower than that of an ATV, which would make it less prone to tipping when crossing a steep dune sideways. ATV riders are always shifting their weight to adjust the overall CG to match the terrain.

ProtoDie
08-16-2012, 06:21 AM
depending on ride height the seat is approx 15"

so it is way lower than atvs

Yes, the inline reverse unit is what we were planning on using with the 650 engine and any other that do not have reverse.

or, there are many 400s with reverse. one could also put a big bore kit on a 400 which opens up many engines

I think you have picked the best engine that has reverse for the new MXT rail. All things considered, its well balanced, and for a small kid and some adults, it will do fine with that HP/Weight ratio.

What size kid can it fit? Does it come with an adjustable seat to allow someone to grow into it? My son is 9 years old and is growing beyond his LT80, I might have another year on that at best before he dwarf's it. What size/age are your kids and do they fit in it?

By the way, I did get to see the DXT1000 you built today, very nice job. Your customer is quite happy!:cool:

Cool , glad you got to me Morgan. Very nice guy

My kids are now 9 , 12, 14

the 12 and 14 year olds started racing 5 years ago.

depending on size and ability I would say 10-12 on the low side all the way up to adults.
Plan is to build some new ones for the kids and one for me, to rub tires with them on the track.
Need to get caught up on everything else 1st, so this may not happen until fall now. we will see

Martin was very informative and happy with the DXT1000. Might hook up on a dune trip down the road as well.

My son is just turning 9, weighs 76 lbs and is 56 inches tall. Were your kids that size when they started driving the MXT buggy?

no they were smaller when they started racing.
this is the 1st version and were originally 2 seaters for kids.
the next level of MXT is a little bigger than these.
then the next 350-400 version will be very similar to to the current MXT

Yes, 2 seat is pretty much designed and will have all the same suspension and drive train as the single seat,,,,just a different frame.
This may not be built until I get an order for one.
I have a customer in Qatar who is real interested int he 2 seat.
we will see how soon that comes to life


Yes, just about every buggy we build can be bought as a frame or rolling chassis.

Azeriksis
08-21-2012, 02:58 PM
Well if the two seat comes to life in the next 4 5 months i would be very interested in just the frame and probably front end. I may try to set it up with double a arm and install a larger power plant. Im not sure about that one yet. How big a engine you think this thing can handle?

Very nice to say the least!

Looking at the picture of the rear where the chains are shown, do you see any need for a chain guard/roller or tensioner? I am guessing with the side to side articulation, that may be a challenge for the lower chain, but maybe there is no need for it. Just curious if that was an issue....

no challenge,,,,,chain has no issues, plenty of testing on it and noted previously in this thread


this one is a customers,,,,,,so I probably will not be getting any big air time in it off test hill

weight: this one came in at 680lbs.
per customers request the main roll cage tubes are .120 wall on this one which bumps it up over 650lbs


yes I like the ambush tires. 1st set I had on the front was a touch small so I went the next size or 2 up.
these are 22" on the front now

Maybe I'm using wrong terminology, where the 2 chains come together on the shaft, Is that a jack shaft? I'm building the same basic car with a 660 Raptor and need that shaft, bearings, sprockets, mounts and such. I don't need the stiff arm, I'm using the Raptor swing arm. Are those dirt bike sprockets, and if not, can they be?
Let me know what all the parts are and how much $$. You can p.m. me or reply to my email from last week from Cozycampers. I did not understand the reply.

hey Richard,
here is what I sent last week,

we use a sprocket extension shaft we designed

sprocket extension (http://www.protodie.com/Sprocket-Extension_p_195.html)

then run it forward to a jack shaft set up, then back to an articulating straight axle.
These parts can be seen in our XK450 photo gallery, but we do not have them listed separate on our website yet.
If you want the complete rear axle, jack shaft set up, let me know .
this complete rear runs $1400.
if interested, email me direct and I will send some cad design pics showing what is included with the kit email is protodie@protodie.com

Thanks,
Jody / Protodie



I can not tell you how to build yours or what parts you want if you are doing something different in your build and using the quad swing arm.
you will have to tell me what parts you want to use.

don't know if I made this is any clearer,,,, I hope so :D

I have the Raptor swingarm installed and need a jack shaft setup w/ pillow blocks, bearings, what all to install. I'd love to get it from you if it works out. I have the following questions...

*Will the shaft hold up to a Raptor 700?
*Can I use Raptor primary sprockets on the shaft? Gearing options are good.
*Can I adjust the spread of the sprockets?
*Will you sell me the jack separately? W/o the swingarm.
*Sprocket extender.. Will it fit on a Raptor?
*Will it take a Raptor sprocket?
*Can I get it in a custom length?

I'm ready to order these parts as early as yesterday, so maybe we can work something out.

sprocket extension is machined to fit 520 14T sprockets, so should fit that sprocket on a Raptor
