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.

YAMAHA RD 500 V4 REVIVAL

Our Yamaha RD 500 V4 has been hibernating for new modifications in the last year. Major differences: - Reed valve system from Two Stroke Shop (4 x RD 350) - Kart fuel pump - GSX-R 750 radiator refrigeration system is now working well - Corrections to compression ratio of all 4 cylinders At the moment, the 500 will have a gearbox piece from Suzuki LTZ 400 (quad), this way we can put neutral easier. Soon we'll make new videos.

SUZUKI RG 500 UPDATES

WORLD GP 500 LIBRARY

We've created a new interesting content on the STUDIES section, it's the World GP 500 Library where we'll put all the specs of the former WGP 500 2-Stroke bikes. At the moment, it only contains the Yamaha YZR 500 OW23 1975, the Suzuki XR-14 RG 500 1976 and the Yamaha YZR 500 OW35K 1978. We'll update this section often, be in touch with the news section to know the updates.
