Speedway Workshop
The Rotrax MK2



With George Greenwood now in charge of producing the JAP Speedway Engine, the final development came about with the introduction of the 84V Four Valve DOHC engine designed by former rider Mike Erskine.

It should be noted that the Rotrax Mk2 was also available with the JAP 84S short stroke motor fitted.
