Are these bikes going to be California street legal? If they are, that's badass.

Are both the 450 engine and the 550 engine the same price? $3700 is a boatload of cash, but I guess what can you expect from Aprilia? http://fsae.com/groupee_common/emoticons/icon_rolleyes.gif What all is included in that price? Throttle bodies? Exhaust? ECU? Hoses?

-Kirk

[Dan Deussen @ Weber Motor]

Another great benefit is that this engine is originally equipped with a Walbro ECU (Model ECUC) which is freely programmable. It is the same ECU I use at work for the Weber MPE750. If there is interest from teams to use this engine, I would strongly suggest to also use the original ECU designed for this engine. It does not have any internal data logging capabilities like a MOTEC, but there is an agreement with AIM Dataloggers to have an external logger to get all the ECU channels through the serial connection into the logger. Please all teams that are seriously interested in using this engine with the OEM ECU, contact me an I will talk with the guys from Walbro, if you can get the software to recalibrate the maps.

[Mechanicaldan]

[JagLite]

Sounds fantastic to me!
I just wish we were in that price range.
Someday.....

[Vanny]

Just taken receipt of a complete Aprilia RXV 550 Enduro motorbike for Liverpool University, it is quite honestly an absolute beast of a bike and sounds AMAZING.

Biggest problem i'm having here in the UK is being able to find the software to access the ECU and start getting to grips with it! For the time being the bike is complete and being driven to run the engine in, a week today see's me starting to take the bike to pieces!

It worked out that if we bought just the engine, then the ECu, wiring, ancillaries etc it would have worked out at over £6000, and we bought the whole bike for a little over £5000 so quite a good saving and we can sell the rest of the components that we don't use on eBay.

Any tips on where to start with this ECU?

[HANSEN PERFORMANCE]

I just ran across this web site and have been looking for guys that have put this motor in carts.. I have bought the crate engine for a atv and need the electrical etc, and would appreciate if any of you have any way to contact sombody that has been down this route. Thnaks in advance Brindley

[JR @ CFS]

How does this figure into costs? I mean, if one of these is advertised around $3-3500, is that not a large amount to be slapping onto your cost report? I mean, you could say that you took the cost of the bike, sold everything else off and took the amount you made, subtracted it from the cost of the bike this is how much it cost you in reality. Just wanted to know what you had planned?

RTFR ;-)

I haven't checked the 2007 rules yet but engines are costed to a displacement/performance formula AFAIK.

BTW your sig might be slightly deformed.

[Mechanicaldan]

As of 10-27-06 you cannot adjust the stock ECU. I've contacted Power Commander, and they are working on a unit, but it's not available either yet.

You're cheapest and best service quality option right now is:

Brian Lewis
Performance Electronics, Ltd.
www.pe-ltd.com (http://www.pe-ltd.com)
"Complete Engine Management Systems for $798"

[Vanny]

You CAN adjust the stock ECU! ANd there isn't a lot to it either!

The standard ECU is a Welbro ECU-C unit and is fully reprogramable, and there are already a number of options for adjusting maps and TPS calibration.
1) By the official Aprilia tool, the AXONE 2000, however these are made by Texa and can be bought from Texa distributors in the UK for around £2000 if you shop around. The AXONE has everything in the one unit you could possibly need, from Osciloscope to DMM, but the cost is huge, you then need the cable (£46), the software updates (£299 a year) and the original maps. Its also a little restrictive as far as adjustments are concerned as it is a small hand held unit!

2) Albeit a Welbro ECU, Aprilia have played with the connection settings so you would have to rewrite a section of the Welbro tools software, or buy the Welbro stock ECU and connection tools (again seems a little bit expensive at around £800 for the ECU and £300 for the software).

3) Best option, TuneBoy software and cables;
http://www.tuneboy.com.au/
software including cable is £229, which has a USB plugin connection to any windows laptop (95 onwards) can log from the laptop and has full control over every aspect of the ECU. Maps are free and downloadable from there website, and software updates come free as best i know. Its also compatible with most of the engine being used in FSAE including the Honda CBR 600 and Daytona Triumph.

Trick to the Tuneboy is that they don't yet advertise that they have the software for the Aprilia XV engines as its in testing as i type and should be available within the next two weeks.


Im very much against anything like power comander on this ECU as it is so good as stock and fully customisable when you hook up using a PC, the added weight and complication of the Power Comander and the restriction of what can be done with the power comander makes it a no brainer for me. I know the trouble we had last year trying to slap a piggy back unit onto a Triumph Daytona engine and it really made the car suffer!

Have a look on the Aprilia XV forums and theres a lot of activity around the subject!

[Chris Boyden]

Damn, that is a sweet little motor.

only 60 lbs? yikes.

[Mechanicaldan]

Thanks for the update Vanny. 229 pounds is what? $450 US + shipping?

[Vanny]

I make it to be about $435 and i think the price includes the shipping! Biggest bonus for us is that the same software works for last years car and adding in the triumph cable and second license key is only like another $60!

you can also pay via paypal which given its an international purchase gives some additional security! Most of the people that have discussed the Tune Boy with me have been from the US so i wonder if there is a dealer out there? Would shave a lot of time off the delivery!

I'll be ordering a copy this week and will let you know (in a new topic) when it arrives!

[Arturo Mendieta J]

Hi Mechanicaldan:

I would like to know how do we can get this motor and the shipping costs to México (of couse the time of delivery) here is my email: mendieta.arturo@hotmail.com, our team (UAEMEX RACING) is interested in a complete quotation (incluiding discount program if it is available and th complete list of accesories for the motor (competition kits etc)) thanks a lot

Regards

[e46mthree]

greetings

just as an fyi, there is a good forum specifically for the Aprilia SXV/RXV motorcycles - the bikes that use this motor. lots of good experience and expertise

http://www.apriliaforum.com/forums/forumdisplay.php?f=50

regards

[Mechanicaldan]

Some more motors to came in!!! Enjoy the pictures, and don't drool too much on your keyboard. The 3 pictured are RXV 550s. The minor difference is lower gearing. See the ratios listed above.

Cheers,

Dan

[Big Bird]

Dan,

Big ups for your efforts in sourcing these engines for FSAE use. It's not easy sourcing crate engines, especially when you are going into bat for other teams as well. Good stuff.

I can't wait to see these cars on track. It would please me no end to see competitive twins, fours and singles all dicing it out for the honours.

Cheers

[Vanny]

Tuneboy has this week been released for the RXV/SXV engines, it can be found on there website at £220 (more expensive than there others because you get a genuine Aprilia cable with it, and the cable alone costs some £135!!!) they will ship globally and it's worth speaking to them about Educational discount!

www.tuneboy.com.au (http://www.tuneboy.com.au)
www.tuneboy.co.uk (http://www.tuneboy.co.uk)

I've also been speaking directly to Putolinea (people that make the recommended oil) and they seem very keen to deal, perhaps if enough people where interested in the states you could buy bulk! And if your getting engines through this thread then you should be able to find others to go in with bulk purchases?

I'll look to a new thread regarding the ECU once i have it in my hands http://fsae.com/groupee_common/emoticons/icon_biggrin.gif


Mechanicaldan, any ideas on shipping costs to the UK? I think we will be needing another engine next year, it will be the MXV with any luck, but if we can get another RXV without buying a whole bike i'd much rather go with that! Only thing we would need is the ECU and loom (or a plug!)

[Mechanicaldan]

For shipping cost estimates, go to www.ups.com (http://www.ups.com) The crates will be shipped from zip code 70503. My best guess for shipping weight of crate and motor is 100 lbs.

[Kirk Feldkamp]

They're talking about you guys over on ekartingnews.com too. Sounds like there are a bunch of superkart guys that are looking to pick up these engines.

Vanny,
I don't see where on the website TuneBoy is compatible with the CBR600? Is there something you know that is not posted on the website?

[Wesmo]

Hi, We just brought a SVX550 aprilia engine and looking for a CAD model of it. Any body have it on file or know where we can get one????

[Vanny]

Wesmo, PM me with an email address and i should be able to sort something out! Where are you based.

Wizard, seems your right, i could well be mistaken as i can't find it either, but somone does off the shelf solution for the CBR i think!

[Mechanicaldan]

I just added the dealer contact to the original post. You can now contact the dealer directly.

[rgv500]

Hi All,

I have been researching these motors for a few days and came across this site.

I am very interested in the 550 motor for a motorcycle conversion. Check out this link of David Howard's bike that he built for a customer. Project RSXV550 (http://www.spagforth.com/rsxv550_project_log.htm) I have been speaking with Dave and he has offered his help. So back to my point, I would like to purchase the 550 motor, SXV or RXV , I still have to check the ratios. Also on a side note, check out my site and my own conversion. rgv-500.com (http://www.rgv-500.com)

Can anyone confirm the price or the motor and everything needed to run it, such as programmable ECU and wiring harness.

Any information would be very appreciated.

Con

[Hammock]

Can anybody accurately assign a value to engine weight or transmission weight?

[448171]

i would like to ask the physical size(height,width and length) of the SXV 550 engine.Becase i want to know the dimension to design a chassis for racing car
THanks

[Aaron@Kaist]

does anyone know if these motors are still available? and how I could get one?
