Calculate GP / ROAD / Off-Road 2-Stroke exhausts for optimal performance based on the legendary portuguese tuner LuFo Racing.
It will have in account your gearbox ratios if provided and alerts if Exhaust Port width is too large with piston ring failure.
This module also provides results for BMEP, Max EGT, Exhaust Port Width % of Bore, New Exhaust Port Width, Cylinder Exhaust Port Diameter
New feature of RacingSM Software, the 2-Stroke Exhaust Segment Splitter.
Split your calculated 2-Stroke exhaust up to 42 sections with regular length or even more with irregular lengths.
Great tool for those who are building exquisite format exhausts, one of the largest benefits of this module is that it can be used with any Exhaust formula results ( LuFo, Blair etc )
One of the most important features of RacingSM Software is the BIKE DYNAMICS module.
Here you’ll be able to compare 2 bikes with different specifications in order to analyse the results and possible differences obtained.
This simulator is specific for straight line acceleration on drag strip or road, there are a lot of input data
which must be accurate in order to obtain also accurate results.
You can compare 2-Stroke and 4-Stroke bikes.
This module allows the study of gearboxes and know how a gear ratio change can affect the bike performance.
This is particularly useful for those who GP race, because depending of the Circuit, the modification of secondary transmission might not be enough and it would be considered the change of some gear ratios.
Without a tool to immediately know how a change affects, it's very difficult for a tuner / mechanic to know how the bike will run.
Another very useful feature is the ability to fill with your Dyno Curve values, your current secondary transmission, rear wheel dimensions, the CdA aerodynamic coefficient and the module will calculate real speeds and necessary rear wheel horsepower on 5th and 6th gear and compare with your Dyno Values.
If you have enough rear wheel horsepower at a certain real speed, a green cell will appear, if the value is almost there, an orange cell will appear, if it simply doesn't have the necessary horsepower, a red cell will show.
You can calculate the gaps between gears, understand if it's GP, Close-Ratio, Street, Wide gearbox and how it affects on real life performance with calculated real speeds given a certain transmission, RPM, Aerodynamic, weight coeficients.
Some of our customers feedback
I was searching for a 2-Stroke software that could help me on my Drag project in 2015.
After using some of their programs such as the Bike Dynamics simulator and the Cylinder Head Design, I've improved my Drag times.
Bought their EXHAUST Package.
Already built one BLAIR exhaust and it works fine, now I'm trying the LuFo one to compare.
Since I saw RacingSM promoting their software on their Facebook page, I've decided to order the FULL Package.
Overall had helped me a lot on my 2-Stroke hobby as an enthusiast.
I've discovered RacingSM Software on their Facebook.
Ordered their FULL Package and I've been making some progress on my personal racing 250 project.
I'm an old-school guy who has a 2-Stroke collection and I love the mechanics.
Found their software on a Forum, ordered it to see if it would help.
Already made pipes for my RD 400 and they're loud and crisp, good power!
I have adapted a programmable ignition on my 135cc engine and then ordered RacingSM Software.
The Ignition Timing program helped me creating a custom map with success.
Helped me a lot on my little 80cc project, specially the LUFO Exhaust Calculator.
My engine now revs freely up to 14 000rpm !
I ride on high altitude with my KTM 250 Enduro and sometimes the jetting wasn't fine.
Discovered RacingSM Software and noticed they had the Carburetor Tuning program and decided to give it a try.
Until now I'm satisfied.
I was looking on the Internet for some software that could help me on the gear ratios quest for my little Yamaha TZ 125.
Just found out that RacingSM had the Gearbox Analysis and their Bike Dynamics, which has been very useful up until now.
I know RacingSM for a while from their Facebook page.
After they've promoted their software, I've decided to give it a try and ordered their EXHAUST Package since I wanted to build exhausts for my big-bore 100cc.
I was searching for a software that allowed me to calculate racing 2-stroke exhausts.
Ordered the EXHAUST Package and already tried their dimensions with some degree of success.
I think it's a good price for its value.
The 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.
Send us an email to email@example.com and we will talk about a special price for multiple license acquisition.
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.
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.
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
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 with LuFo Racing philosophy, know how to change gear ratios depending on racetrack, simulate real-world performance with our Bike Dynamics Simulator.
Most of RacingSM Software modules have the SAVE option where you are able to save your data in files which can be opened later.
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"
Due to high complexity of the different RacingSM modules which envolves a big UI (User Interface), it's not possible to contain all data/results on the actual Smartphones / Tablets display.
This will be a Windows Software only version.
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.
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 .
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 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.
We believe that using this software will help your 2-Stroke development or racing results on different types of competition.
At the moment, we have a special 2-Stroke bike collection:
