The 500cc class era was the former pinnacle of motorcycle world championship racing. Two stroke technology producing the most powerful and exciting engines ever seen!

At this time, the top class of GP racing allowed 500 cc displacement with a maximum of four cylinders, regardless of whether the engine was a two-stroke or four-stroke. Consequently, all machines were two-strokes, due to the greater power output for a given engine capacity. This ended in 2002 when the 990ccm four stroke class was introduced.

Today many fans hugely miss these brutal machines as they have a special place in our hearts. The nostalgia conjured up from just thinking about the sights, smell and sound of the brutal two-stroke bikes is immense.

Suter Racing Technology (SRT) has a long motorcycle racing history, starting in the mid 90.s During the racing activities in the 250cc and the 500cc world championship, Suter Racing designed and developed various engine components, such as cylinders, crankshafts, carburetors, exhausts systems and various chassis components. Suter Racing was also deeply involved in the development of the Swissauto 500 / MuZ. This GP500 machine achieved 1999 two pole positions and many top ten results competing against all the big Japanese factory machinery.

Since then Suter Racing has been involved in many different motorcycle racing classes, developing the engine of the Petronas FP1 Superbike, the rolling chassis of the Ilmor SRT X3 and the Kawasaki Ninja ZX-RR MotoGP machines, resp. in the recent years designing its own Suter-MMX product line of racing motorcycles, wining several world championship constructor titles.

We felt however, it is time to revive the two-stroke bikes from the Golden Era …
