RacingSM was created by 2 brothers, the older one, Ricardo and the younger one Pedro.
Our main purpose was and still is, to share the 2-Stroke information and passion all over the World, in order to remain the "2-Stroke flame" alive.

The first version of this website was online in 2002 when Pedro decided to create a "virtual place" to expose our ex-Kawasaki KDX 200 Supermoto and Honda CRM 50 modifications & engine tuning.
The years have passed, and new bikes arrived such as our father's Polaris Scrambler 400 in 2003, the mythic Yamaha YFZ 350 Banshee in 2005, the legendary Yamaha RD 500 V4 also in 2005, the 2-Stroke GP 500 replica and our recently aquisition in 2007, the exclusive Honda RS 250 for Trackdays, a GP machine.

We also have two 4-Strokes, since 2006 a KTM 520 EXC for dual purpose (Supermoto & Woods & Desert) and since 2007 a Japanese imported Honda CBR 250RR 1991' model, the ultimate Screamer with its 20 000rpm and 45bhp.

We hope you enjoy our website, not only about our bikes/projects, but also about the Trips/Chronicles, Friends Projects and some Studies .

Thank you very much for passing by.

We took our HONDA CBR 250RR 1991' to the dyno. The temperature was around 30º, the dyno didn't have wind fan, 2 runs were made, the first one in 4th gear and the second one in 6th gear. The power figures were 47.1 crank HP and 43.2 RWHP, impressive values for a 19 year old engine/bike with already 45 600 km made. Feel free to check out the dyno video @ HONDA CBR 250RR section

SUPERMOTO TRIP TO ALGARVE

On the weekend of 28, 29, 30 March we've decided to make a supermoto trip to Algarve in our KTM 520 EXC Supermoto and the recent aquisition Husaberg FS 650e Supermoto. We went to the new AIA (International Portimão Circuit) and then to the twisty roads of the Monchique mountain. Pedro made 2 onboard movies of the twisty roads on the KTM, the videos are now available in the KTM 520 section.

DOMA SILENCER HUSABERG FS 650e

After searching for exhausts for our Husaberg FS 650e, the best compromise between price, sound level and performance ended in buying a DOMA silencer. From the dynos we've saw, the DOMA silencer is the on of the best to obtain peak HP (less 1-2 hp than the Akrapovic), but it offers way more grunt in low and mid-revs, which is the rpm's we wanted to improve. After installing the new pipe, the differences are astonishing, the Berg response is instant since low-revs and makes power wheelies much easier even in 4th gear with 16 - 38.
