Suter MMX 500 – Reviving the 500cc Two-Stroke…Again

Google+ Pinterest LinkedIn Tumblr

Suter Racing’s 500cc V4 two-stroke track bike project is back, in case you didn’t hear. Now called the Suter MMX 500, the ~200hp / 284 lbs motorcycle is set to debut again, as the Swiss firm gears up for the World GP Bike Legends event.

Presumably, not too much has changed on the GP-inspired machine, though we can expect to see an updated set of bodywork, suspension, and other farkles. At the core will remain that beautiful pre-mix consuming engine, in its V4 configuration.

We say presumably, because Suter is staying tight-lipped on this project, simply teasing the Suter MMX 500 with a dedicated website and with dyno-run soundtrack. So…stay tuned.

In the meantime, we have seriously just copy-and-pasted the same photos and information that was available four years. At least we’re honest.
