2015 SHERCO OFF-ROAD BIKES ANNOUNCED

Sherco just announced its line of 2015 motorcycles at a press event near Toulouse, France.  Here in the U.S., Sherco is mostly known for its line of trials bikes, which are produced in Spain. But on the world scene, the company’s line of French off-road bikes is earning more attention. In Great Britain, David Knight and in Italy, the CH Racing team have been showing off the capabilities of the whole line, which includes four-strokes and two-strokes. We couldn’t make it to Toulouse to ride the bikes, but U.S. Sherco importer Clay Stucky is planning public demo rides in the upcoming year. Go to shercooffroad.com for more information. Here are some of the details we received from France.

FOUR-STROKES

250 4T:– Synerject injection system for outstanding throttle response and perfect engine braking management- A pressure sensor is located in the injector body to adjust the gas/air mixture to compensate for air filter contamination- Injection system mapping optimized for flexibility and a more linear power delivery-The cylinder head intake valve is 30mm to optimize the engine performance- Redesigned camshaft for wider operating range – Camshaft timing revised for a wider range of use at low speed and a more linear high speed power delivery

300 4T: – Redesigned camshaft for wider operating range

– Injection system mapping optimized for flexibility and a more linear power delivery- Camshaft timing revised for a wider range of use at low speed and a more linear high speed power delivery

Evolutions that are common 4T:

Engine:

– Selector segment teeth which permits cylindric gear shaft unstead of conical shaft – The gear selector lever has been strengthened and reinforced, it is made out of anodized alege aluminum

Chassis: – Rear frame reinforced – The foot rests have been reinforced with Chrome Molybdenum steel- Swing arm needle bearing area has been reinforced

450 4T:Engine: – New more compact engine design

– Synerject injection system for outstanding throttle response and perfect engine braking management- Engine is equipped with a dual overhead camshaft OHV- Distribution key- Semi PERIMETER specific steel flush welded framework that has been optimized, the wheelbase has been made 18mm longer for better stability at high speeds- Morse / Hyvo Distribution chain for noise reduction of the mechanical moving parts- A pressure sensor is located in the injector body to adjust the gas/air mixture to compensate for air filter contamination

–
Châssis:

– Rear subframe reinforced- The foot rests have been reinforced with Chrome Molybdenum steel- Swing arm needle bearing area has been reinforced

TWO-STROKES

250/300 2T: Engine:

– New timing curve developed for the Kokusan ignition system to provide more power at low speeds and greater throttle responsive – New valve springs that increase engine response in the low and midrange

– Lightweight electric starting system that is located low on the engine (ideal position to maintain a low center of gravity) – The exhaust valve management system has evolved in order to provide improved calibration

– Improved exhaust valve sealing for more power at low revs – Field Validation: optimized the valve adjustment and the ignition timing- ALS7 Alloy Cylinder for high temperature stability and improved cylinder life expectancy- A redesign of the three fixing plates on the crankshaft – The cables for opening and closing the exhaust valve are adjustable- New reinforced gear selector star drum
Chassis:

– Utilizes a design similar to that used on the 4T to provide optimal front wheel grip – Optimized the design of the fork legs and yokes, in order to provide more flexibility and comfort but more torsional rigidity for traction – Rear frame reinforced – Footrest support reinforced – FMF original exhaust system on the 250 2T to improve power in low speed and more high RPM – Framework changed to include more robust mounting bracket bolts- Rear subframe reinforced- The foot rests have been reinforced with Chrome Molybdenum steel- Swing arm needle bearing area has been reinforced
