Information

 
Anxiously awaited, the exciting new Scorpa SY250F 4-Stroke was previewed at the French World Round in June 2005.  A number of innovative features stand out, including the dual under seat exhaust, new perimeter frame design with cast aluminum pieces joined to both round and oval tubing, two piece rear fender, carbon fiber side panels, and heavy duty wrap around skid plate. The fuel petcock is easily accessible on the right side of the gas tank, and a choke lever is mounted on the bars above the clutch lever.

Based on the liquid cooled, double overhead cam, 5 titanium valve, Yamaha YZ-250F engine, the SY-250F has been heavily modified for trials.  Modifications include trials specific transmission, camshafts, flywheel, clutch, ignition, etc.  Using Aerospace and Formula 1 technology, the frame uses chrome molybdenum tubing linked to a forged billet aluminum sub-frame.   The new, 700 gram lighter,  swingarm uses extruded honeycomb billet aluminum linked to a new Paoli rear shock.  The brakes are of a new design, with a 182 mm diameter floating disc up front, and 150 mm non-floating disc on the rear.  The two new discs have been increased to a 3 mm thickness to improve braking performance and reduce noise.

For rider comfort, the handlebar mounts and footpeg mounts include variable positioning, allowing them to be moved forward and backward, as desired.  The entirely new air box and filter shifts from the traditional foam design, and instead uses a cotton air filter element borrowed from Formula 1 racing.  Without a doubt, the aluminum dual exhaust draws your attention.  The unique design feature utilizes the exhaust as the rear sub-frame, to add strength and save weight.

Just as with the SY-250 2-Stroke, Scorpa is offering the Long Ride tank/seat combo as an aftermarket

Just in case you can't decide between the SY-250F Racing, and the SY-250F Long Ride, Scorpa has taken care of that dilemma for you, by making the Long Ride tank/seat unit available as an accessory unit.  You can easily switch back and forth between Racing & Long Ride configuration, and have the best of both worlds!
