brian r Posted January 20, 2004 Report Share Posted January 20, 2004 Does anyone know where to find the engine specs? Bore, Stroke, valves, cam profile, flywheel weight? Quote Link to comment Share on other sites More sharing options...
astrolounger Posted January 20, 2004 Report Share Posted January 20, 2004 I would try the Yamaha page.Can't see how the specs would differ much from the TTR. Quote Link to comment Share on other sites More sharing options...

exmxer Posted January 31, 2004 Report Share Posted January 31, 2004 Does the Scorpa use the Yamaha TTR motor? How does it work for trials? I would think that it would be a fun bike to ride. exmxer Quote Link to comment Share on other sites More sharing options...
