Welcome!
We are RacingSM.
2-Stroke enthusiasts & tuners from PORTUGAL

We are 2 portuguese brothers, Pedro and Ricardo, we love and are 2-Stroke enthusiasts. In 2002 we've created RacingSM to promote our personal 2-Stroke projects and also to help others on their bike & engines development.

Developed by Pedro, with more than 20 000 lines of code, all the know-how applied to software comes from us and also a lot from the legendary Portuguese 2-Stroke tuner LUFO Racing, this software is directed for all 2-Stroke: Enthusiasts, Tuners, Mechanics, GP, Drag Racing, MX, Enduro.
There is no 2-Stroke displacement limit for our Software, for example you can have a 125, 250, 500, 700 single-cylinder and our modules will work flawlessly. From a 49cc Racing engine, to a GP 125 engine, or a 1500 Mercurial Triple engine, or a 250 Kart engine, RacingSM Software suits all. We believe that using this software will help your 2-Stroke development or racing results on different types of competition.
Bellow is our 2-Stroke collection ( for more info of our projects please check @ www.racingsm.org ):

    No.
    The WINDOWS RacingSM Software is sold per license, you can only install it on 1 computer / Hard-Disk.
    If you install it on different hard-disks, it will only work on the one which the Activation was made, so choose wisely on which computer you will install.
  • 02. I want to install WINDOWS RacingSM Software in more than 1 computer, what can I do ?
    Send us an email to racingsmsoftware@gmail.com and we will talk about a special price for multiple license acquisition.
  • 03. What is your refund policy?
    Windows FULL Package: only before activation, after activation there is no refund as there is no guarantee that you have deleted the software, so make sure you want it before ordering.
    Mobile SaaS Package: no refund.
  • 04. Are these the best prices for the Software Packages?
    Well, this has always a subjective answer.
    If you analyse the competition, not only they offer a lot less features, but their prices are similar than this complete Software with independent 27 modules/programs ( WINDOWS ) and the SaaS Package with 19 modules/programs
    RacingSM Software has features for many different areas ( 2-Stroke Exhausts Development, Drag Racing Features, Simulators, Carburetor Tuning, Connecting-Rod Analysis etc )
    With all this Know-How along with LuFo Racing heritage, we believe this is a very fair price.
  • 05. I am just a simple 2-Stroke enthusiast, will this Software help me?
    Of course!
    Check out all our modules, each one of them can help you develop your 2-Stroke bike/engine in order to improve performance along with good reliability.
  • 06. I build engines for racing [Drag-GP-MX-Enduro], will this Software help me on my development?
    Of course!
    RacingSM Software has some specific modules that can help tuners/builders on their race engines/bikes in order to improve performance and reduce lap times.
    Build 2-Stroke exhausts, know how to change gear ratios depending on racetrack, simulate real-world performance with our Bike Dynamics Simulator.
  • 07. Can I save the calculations/simulations I have made on the modules?
    Most of RacingSM Software modules have the SAVE option where you are able to save your data in files which can be opened later.
  • 08. I have installed WINDOWS RacingSM Software, but it won't run!
    First check our Minimal Requirements, if your computer has all the requirements:
    Try install the .NET Framework 4.0 , which is provided on your package with the filename " dotNetFx40_Full_setup.exe "
    For SaaS Package, check out if your device and browser is compatible.
  • 09. I have some questions about certain modules of RacingSM Software, can you help me?
    Sure.
    But before sending us an email or Facebook message, please read carefully our User Manual that is provided on the package or here on our website.
    Probably your questions will be answered after reading the User Manual.
  • 10. Are the results obtained from RacingSM Software modules reliable ?
    The best answer is:

    GIGO stands for “ Garbage In Garbage Out ”.

    What this means is that we can’t expect to get better quality results than the quality of the data that we input. Having said that it is true that some parameters only have a small influence on the performance and so the accuracy of those parameters is not critical.
    Some of the required input data is easy to come by but other data may be difficult. Internet, magazine road tests and manufacturer’s manuals are a good source of some data. The following will consider each piece of data individually and discuss its importance and availability .
