SUZUKI ANNOUNCES BRAND NEW 2018 RM250


Suzuki is planning to bring back two-strokes with a clean-burning, fuel-injected, all-new screamer engine.
The internet rumour machine is in full swing over the whisper Suzuki may be returning to the smoker stable for its future off-road weapons.

The Suzuki RM250 was a venerable racing machine, although long in the tooth by the time Suzuki discontinued production of the RM250 at the end of 2007. It’s never good news hearing about a bike going through the wood chipper, because it means the end of a generation. Manufacturers pour millions of dollars into research and development for a single model. Let that sink in for a minute. Those manufacturers expect a return on their investment, and when they think the well has run dry, they either reinvest funds or move along. Suzuki took the latter route with the RM250. That’s still sad to think about.



On the drawing above, tagged with the numbers 71, 70 and 74 can be seen a fuel injection system. The unit is mounted low-down in the cylinder and angled upwards – this is so that the fuel ‘cone’ that is sprayed into the chamber as an atomised mist is launched over the second scavenger port in the cylinder.

Because the fuel is sprayed so finely and can be directed into the chamber so accurately, plus be timed so expertly, the burn is very clean and efficient meaning that emissions are very low indeed. The fuel is used as a cooling element inside the cylinder to further increase overall engine efficiency.
Compared to the old two-stroke feed technology this is light-years ahead and clearly Suzuki is confident that is can build a modern, light and powerful two-stroke motor that will be compliant with various legislation around the world.
Here Suzuki are introducing the BRAND NEW 250 2 Stroke!
